Though these costs vary greatly worldwide, “the total annual global losses due to dairy cattle diseases are greatest in India, the US, and China.”
Investigate the financial ruin dairy cow illnesses like mastitis, ketosis, and lameness cause. This study provides a thorough worldwide view and uncovers why specific ailments are more expensive than others.
The Hidden Costs of Dairy Cattle Diseases: An In-Depth Global Economic Analysis
Under the direction of Philip Rasmussen of the University of Copenhagen, a team of researchers has conducted a thorough and innovative study reported in the Journal of Dairy Science that offers a comprehensive worldwide economic evaluation of dairy cow illnesses. Examining statistics from more than 180 milk-producing nations, the research painstakingly examines the financial impact of 12 major dairy cow illnesses and health issues. The researchers not only precisely calculated the worldwide losses using a comorbidity-adjusted technique but also guaranteed that any overlaps in illness effects were considered, hence providing a more accurate estimate. This thorough investigation emphasizes the global broad and different economic load dairy cow illnesses cause.
Twelve major dairy cow diseases, including mastitis (subclinical and clinical), lameness, paratuberculosis, displaced abomasum, dystocia, metritis, milk fever, ovarian cysts, retained placenta, and ketosis (clinical and subclinical), were investigated economically. These illnesses raise culling rates, affect milk output, and change reproductive rates. Precise approximations of their effects enable improved control and lower financial losses.
With a comorbidity-adjusted economic analysis, the researchers painstakingly calculated the cost of dairy cow illnesses. They considered characteristics like milk output, fertility, and culling rates, and compiled data on twelve illnesses from literature covering over 180 milk-producing countries. They standardized these measures for consistent comparability across research to guarantee dependability. This rigorous methodology ensures the accuracy and reliability of our findings.
They then combined these datasets into thorough estimations using sophisticated meta-analysis methods ranging from basic averaging to complicated random-effects models. Correcting for comorbidities was essential to avoid overestimation and to recognize the concurrent incidence of many illnesses with their combined financial consequences.
Equipped with these consistent projections, the group modeled the financial influence using Monte Carlo simulations. They precisely estimated the economic losses by including country-specific data on illness incidence, lactational prevalence, herd features, and economic criteria.
This study depends on adjusting for comorbidities to guarantee that overlapping health problems do not distort the economic effects of different illnesses. Dairy cow infections often coexist and cause combined health problems that distort statistics. Considering these comorbidities helped researchers to estimate the cost more precisely. Without this change, 45% of the worldwide losses would have been exaggerated, distorting the actual economic weight of the dairy sector. This change offers a more accurate knowledge of the financial effects related to illnesses of dairy cattle.
Dairy Cattle Diseases: A $65 Billion Annual Burden with Subclinical Ketosis and Mastitis Leading the Costs
According to an extensive analysis of dairy cow illnesses, yearly worldwide losses amount to US$65 billion.

Since last month, the milk production forecasts for 2024 and 2025 have been constant, suggesting a harmonic approach to cow inventory levels. This consistency and the expectation of higher cheese shipments have resulted in an upward estimate for commercial exports on a fat basis for 2024 while skim-solids-based exports stay the same.
The forecasts of solid worldwide demand provide a picture of the global dairy industry and drive the increasing export projections for fat and skim-solids bases. Farmers, producers, and other interested parties, including manufacturers, depend on this realization as they make plans for 2025. Driven by planned imports of butter and milk protein-containing products, import forecasts for 2024 are also on the rise; similarly, projections for 2025 show the same increases.
The recent price increases’ positive trend has helped raise the price estimates for butter, cheese, whey, and nonfat dry milk (NDM) for 2024. Milk prices in Class III and Class IV are thus rising. Furthermore, the all-milk price projection was raised to $21.60 per cwt. For those in the market, this upward trend in pricing shows encouraging signals.
Butter, cheese, and whey prices will rise as the strong demand for dairy products continues until 2025. Though the NDM forecast stays, the same, higher product costs have driven up the Class III and IV milk price projections. The predicted 2025 all-milk price these days is $21.50 per cwt.
Beef Forcast
Looking forward to 2025, increased slaughter for outlying quarters more than offsets decreased predicted slaughter in the first quarter. These cattle will most likely be sold and killed in the second half of the year because they are put on feed in the first half. Furthermore, clothing weights are projected to stay high throughout 2025.
Given the limited cattle and beef supply, average prices for 2025 should be higher than those for 2024. With prices hitting $186 per cwt in the fourth quarter, the fed cattle price projection for 2024 was calculated at $184 per cwt. The average throughout 2023 per cwt was $175.54.
Feed Supply, Price Forecasts
The WASDE data from the USDA provides possible information on dairy feedstuff availability and pricing:
Comparatively, the 2024-25 U.S. corn projection is the same this month compared to the previous month.
Forecasts for global coarse grain output for 2024–25 show 1.4 million tons down to 1.511 billion. Relative to last month, this month’s foreign coarse grain prognosis shows lower output, somewhat greater trading, and smaller ending stockpiles. Foreign corn output is slightly higher, rising for Ukraine and Zambia, somewhat offset by a decline in Russia.
From the May projection, the expected season-average corn price received by growers remained the same at $4.40 per bushel, down 25 cents from the 2023-24 average of $4.65 per bushel.
This month’s U.S. soybeans for 2024–25 show greater starting and ending stockpiles.
Higher starting stockpiles indicate lower crush for 2023–24, down 10 million bushels on less soybean meal.
The Bottom Line
Based on the USDA’s most recent estimates, milk output is predicted to be constant for 2024–25 despite expected price rises resulting from significant demand for dairy products. Likewise, beef output is steady, yet tighter supply might lead to more expensive goods.
Though pricing trends have dropped compared to past years, feed supply predictions for maize and soybeans reveal an unaltered view. As dairy and cattle farmers control expenses, this might provide both possibilities and problems.
Juggling consistent output, price changes, and feed expenses will be vital for the agricultural sector. Markets for dairy and beef must adapt and be creative to ensure profitability and sustainability.
Key Takeaways:
Milk Production: Milk production forecasts for 2024 and 2025 remain unchanged from last month, with only slight adjustments. The 2024 production is estimated at 227.3 billion pounds, a modest increase from 2023’s total of 226.4 billion pounds.
Milk Prices: Price forecasts for butter, cheese, whey, and nonfat dry milk (NDM) are raised for 2024 due to recent price strength. The Class III milk price is now forecast at $17.90 per hundredweight (cwt), while Class IV is projected at $20.50 per cwt. The all-milk price is raised to $21.60 per cwt.
2025 Milk Production: The production estimate for 2025 remains steady at 229.3 billion pounds. Prices for butter, cheese, and whey are expected to rise due to strong demand, while NDM prices remain stable. Class III milk is forecast at $17.70 per cwt and Class IV at $20.10 per cwt. The all-milk price for 2025 is $21.50 per cwt.

This versatility and value highlight why Jersey Milk’s milk’s nutritional characteristics are indispensable.
Jerseys: Small Stature, Significant Advantages for Dairy Operations
Jerseys, with their smaller size than Holsteins, offer unique advantages to dairy operations. Their compact stature means they consume less feed and optimize barn space. Despite their smaller size, Jerseys excel in converting feed to milk with high protein, milkfat, and calcium levels. This unique trait empowers dairy farmers to maximize their resources and enhance their herd’s productivity.
Jerseys also maintain a higher dry matter intake (DMI) after calving, which is crucial for meeting energy needs during lactation and reducing metabolic disease risks. Their increased chewing improves rumen stability and fiber digestibility, making them more efficient feed converters than other breeds.
Scientific Validation: Jerseys’ Superior Feed Conversion Efficiency
Scientific research demonstrates that Jerseys are significantly more efficient than Holsteins at converting feed into milk components. Studies show that when producing the same amount of protein, milkfat, and other solids, Jerseys need 32% less water, use 11% less land, and consume 21% less fossil fuels. This efficiency highlights their minimal environmental impact.
Moreover, Jerseys extract and utilize energy from their diets more effectively, leading to higher nutrient levels in their milk. A glass of Jersey milk contains 18% more protein, 29% more milkfat, and 20% more calcium than Holstein milk. This nutrient density underscores Jersey milk’s superior quality and enhances the breed’s value in the dairy industry.
Key Nutritional and Health Differentiations: Feed Intake, Energy Metabolism, and Overall Health
When examining Jersey’s dietary and health needs, three areas stand out: feed intake and digestion, energy metabolism, and health.
Regarding feed intake and digestion, Jerseys maintain a higher DMI post-calving relative to their body weight. This, alongside spending more time chewing, supports a stable rumen environment, enhancing fiber digestibility and feed conversion efficiency.
In terms of energy metabolism, Jerseys extract more energy from their diet. Energy metabolism refers to the chemical reactions in the body that convert food into energy. Efficient energy metabolism is crucial for cow health and milk production, as it ensures that the cow’s energy needs are met. Jerseys’ ability to extract more energy from their diet means they require fewer resources than Holsteins, making them more environmentally sustainable. Their milk is richer in protein, milk fat, and calcium.
Regarding health, Jerseys’ smaller size and robust hooves reduce lameness and disease risks. Their higher rumen pH offers better resilience against acidosis. However, fewer vitamin D receptors in their gut increase their risk for milk fever, necessitating careful DCAD management.
Another critical difference is Jersey’s faster maturity rate, which increases their risk of becoming overweight. Effective strategies include housing them with older Holsteins to better match their nutritional needs and promote healthy growth.
Health Advantages: Why Jerseys Outshine Other Breeds in Dairy Farming
Jerseys boast substantial health benefits, enhancing their appeal to dairy farmers. Their tiny, hard black hooves produce fewer lameness issues, like hairy heel warts, common among larger breeds. This durability ensures Jerseys are productive, reducing mobility issues and associated treatment costs.
Additionally, Jerseys maintain a higher rumen pH, granting them better tolerance and quicker recovery from acidosis. This trait helps stabilize digestive health during stressful periods like calving, ensuring high feed efficiency and milk production without frequent digestive upsets.
However, Jerseys are more susceptible to milk fever due to fewer vitamin D receptors in the gut, making them three times more likely to experience this condition than Holsteins. Milk fever, also known as hypocalcemia, is a metabolic disorder that occurs when the cow’s blood calcium levels drop rapidly after calving. It can lead to muscle weakness, reduced feed intake, and even death if not managed properly.
Managing this requires proactive measures like monitoring dietary cation-anion difference (DCAD) and calcium mobilization strategies. Regular urine pH checks can help adjust prepartum rations. When current rations fall short, adding anionic salts can effectively prevent milk fever, safeguarding Jersey cow health and productivity.
Optimizing Health and Productivity through DCAD Monitoring and Glucose Enhancement in Jerseys
To manage Jerseys effectively, it is crucial to monitor and adjust the dietary cation-anion difference (DCAD) and enhance glucose production. These strategies will help mitigate the risks of milk fever while supporting overall energy balance and immune function.
Jerseys maintain higher dry matter intake (DMI) post-calving, aiding in rumen health and feed efficiency.
They are efficient feed converters, extracting more energy from smaller absolute feed intake.
Jersey milk is nutritionally superior, with higher protein, milkfat, and calcium than Holstein milk.
Jerseys mature faster, requiring careful feeding strategies to avoid overweight issues; housing with older Holsteins can help.
Jerseys have healthier hooves and higher rumen pH, reducing lameness and acidosis risks.
Monitor DCAD status closely to prevent milk fever, utilizing calcium mobilization strategies as needed.
Enhancing glucose production can mitigate negative energy balance and support immune function.
Breed-specific research is essential for optimizing Jerseys’ health and productivity.
First, consistently measure your cows’ urine pH, aiming for levels between 6.2 and 6.8. If current rations don’t achieve these levels, add anionic salts to the diet to improve calcium mobilization and prevent milk fever. Maintaining optimal DCAD is essential for Jersey’s health during its transition period.
Enhancing glucose production is vital to counteract the negative energy balance seen postpartum. Increase the energy density of rations by using highly digestible forages and grains, and consider glucose precursors like propylene glycol or glycerol. These can be administered postpartum to address the energy gap, supporting energy reserves and immune function.
Implementing these strategies requires careful observation and flexibility. Regular monitoring and timely dietary adjustments will help keep Jersey herds healthy and productive, meeting the demanding targets of modern dairy operations.
The Bottom Line
Jersey cattle have distinct nutritional needs that require special attention. Their efficient feed conversion, smaller size, and unique metabolism necessitate specific feeding and management practices to ensure optimal health and productivity. Addressing these requirements is crucial for the success and welfare of Jersey herds. By focusing on feed intake, energy metabolism, and health, farmers can maximize the potential of Jerseys, contributing to sustainable and profitable dairy farming.
Utilizing Jerseys’ superior feed efficiency and unique health benefits, dairy farmers can boost milk production and overall herd welfare. Jerseys’ higher milk solids and lower environmental impact enhance their value in sustainable farming.

Reuters’ Leah Douglas and Tom Polansek highlighted a critical issue in the agricultural sector: dairy cows in five U.S. states have died or been culled due to the avian flu. State officials and academics confirmed that the affected cattle either died from the virus or were euthanized by farmers after failing to recover. This development could have significant economic implications, considering the higher costs of raising dairy cows than poultry.
The Financial Fallout: Avian Flu’s Deep Economic Impact on Dairy Farms
The economic ramifications of the avian flu outbreak in dairy cattle are severe, straining farmers already on thin margins. Dairy cows represent a much more significant investment in cost and maintenance than poultry. Raising a cow involves substantial feed, healthcare, housing, and labor expenses over several years, making the financial stakes high.
As dairy operations confront this crisis, culling infected cows adds economic pressure. Each lost cow means a direct financial hit and disrupts milk production cycles, affecting farm income. The smaller herd size reduces milk output, lowering sales and profits. The costs of rebuilding herds and replacing culled cows add further stress. These impacts can be devastating for small to mid-sized farms and may lead to closures.
The impact of the avian flu outbreak extends far beyond individual dairy farms, affecting the entire agricultural sector. The ripple effects of the outbreak are felt by feed suppliers, veterinary services, and dairy product distributors, all of whom experience a drop in demand due to the reduced number of cows. This highlights the need for robust disease management and support systems to mitigate future outbreaks and protect the livelihoods of those dependent on the agricultural sector.
Secondary Infections: The Underestimated Threat to Dairy Cattle Health
Secondary infections significantly contribute to the mortality of dairy cattle affected by avian flu. As the virus weakens their immune systems, cows become vulnerable to other infections they would usually resist.
Russ Daly from South Dakota State University explains, “Some animals died not from avian flu, but from secondary infections that thrived in their weakened state.”
Olga Robak from the Colorado Department of Agriculture adds, “Infected cows often didn’t recover their health because secondary infections took hold after their immune systems were compromised.”
Phil Durst of Michigan State University Extension notes, “In Michigan, secondary infections are notably high among infected cattle, further depleting herds struggling to recover.”
Ohio Department of Agriculture spokesperson Meghan Harshbarger confirms, “Most deaths in Ohio are due to secondary infections, rather than the avian flu virus itself.”
Therefore, while the initial avian flu infection is severe, the subsequent secondary infections are proving fatal for many dairy cows, complicating herd management during an outbreak.
Case Studies: Devastating Impact of Avian Flu on Dairy Farms
In South Dakota, a dairy farm had to cull 24 cows—12 that did not recover from the virus and another 12 that succumbed to secondary infections. This illustrates the drastic measures needed to maintain farm health.
In Michigan, about 10% of a farm’s 200 infected cows were culled due to their inability to recover from avian flu, highlighting the severe impact on large-scale dairy operations.
Colorado dairies also culled cows that failed to return to milk production, showing how the virus can significantly disrupt milk output and economic stability.
State Responses: A Patchwork of Impact and Strategies Amid Avian Flu Crisis
State responses to avian flu in dairy cows vary significantly. In Ohio and Texas, officials reported that most cow deaths resulted from secondary infections. Similarly, New Mexico’s state veterinarian indicated that early culling due to reduced milk production has diminished as recovery rates improved. Conversely, North Carolina and Kansas officials reported few to no cow deaths, suggesting a more contained situation.
Expanding Crisis: Avian Flu’s Relentless Spread Across U.S. Dairy Herds
The situation continues to worsen, with avian flu affecting dairy herds in Minnesota and Iowa. This brings the total infected dairies to 86 across 11 states. Since May 30, 18 new herds have tested positive. Recent USDA data shows new cases in three Texas dairies and another in Idaho. Increased voluntary testing by the USDA suggests more cases may emerge as the virus spreads.
USDA’s Pilot Program: A Crucial Weapon in the Fight Against Avian Flu in Dairy Herds
The USDA’s pilot program is a critical strategy in tackling the avian flu outbreak in dairy herds. By urging producers to test their herds voluntarily, it aims to identify H5N1 cases and quickly limit the virus’s spread. Farms must test negative for three consecutive weeks using ‘on-farm bulk milk’ or similar samples to be designated as ‘negative status,’ ensuring herd health and industry integrity.
Achieving a ‘negative status’ is crucial. It provides a framework for disease monitoring and control, preventing outbreaks from becoming more significant crises. Rigorous testing protocols help identify infected animals early, reducing economic losses from culling and secondary infections. Additionally, it restores consumer confidence in the safety of dairy products, which is essential for market stability. Such measures are vital in safeguarding public health and the dairy industry’s future.
Ensuring Food Safety Amid Avian Flu: USDA’s Assurance in the Integrity of Meat and Milk Supplies
As avian flu affects dairy cattle, food safety remains a top concern. The USDA assures that both meat and milk supplies are safe. Rigorous inspections by Food Safety and Inspection Service (FSIS) veterinarians at federal slaughter facilities ensure that only healthy cattle enter the human food supply. Any cattle that do not pass these inspections are excluded.
Additionally, the USDA confirms that milk from healthy animals is safe for consumption, highlighting ongoing efforts to protect public health. These measures not only reassure consumers but also maintain the integrity of the U.S. food supply chain, instilling confidence in the safety of dairy products.
The Bottom Line
The avian flu’s penetration into the U.S. dairy industry is causing significant economic fallout. Dairy cows are dying or being culled due to the virus and secondary infections.

Maximize dairy cow health during the critical transition period. Discover essential strategies for nutrition, metabolic disorders, and farm management. Ready to optimize?
Dairy cows’ transition period—the final three weeks of gestation through the first three weeks of lactation—is critical. Herd production and health may be significantly affected at this crucial juncture by Cow metabolic problems, and other health concerns are susceptible during this period; hence, ideal management techniques are pretty important. Emphasizing nutrition, metabolic diseases, and agricultural management techniques, this paper investigates ways to improve the transition phase. Good management throughout these weeks, with the crucial involvement of veterinarians and nutritionists, will help lower postpartum infections, guarantee seamless breastfeeding transitions, and increase milk supply.
The Crucial Transition Period: From Dry Cow to Peak Lactation
The transition phase of dairy cows, which extends from three weeks before to three weeks after calving, involves significant changes that can impact cow health and output. Therefore, good management is crucial for a seamless transition from the dry cow phase to peak lactation. With the proper management practices, dairy farmers, veterinarians, and nutritionists can feel reassured and confident in their ability to navigate this critical period.
The approximately 60-day dry season is split into the far-off and close-up stages. Cows in the far-off phase usually maintain physical conditions on low-energy, high-fiber diets. Food changes during the close-up period as calving approaches to prepare the rumen for lactation and avoid metabolic problems like ketosis and fatty liver disease. At this point, proper diet is vital.
Calving is a taxing event requiring much energy and effort for milk production. Hormonal changes, including an increase in estrogen and a fall in progesterone, facilitate birth and lactation. To protect the health of the Cow and calf, postpartum inflammation and stress must be closely watched and sometimes treated medically.
Early Lactation: Cows’ high energy needs when milk production begins after calving usually result in a negative energy balance. The liver uses much fat for energy, which, if not appropriately controlled, could lead to ketosis. Calcium needs for milk production rise, thus increasing the risk of hypocalcemia. Health and output depend on management techniques, including optimizing dry matter intake and rumen function.
Throughout these phases, dairy cows alter physiologically, which affects their general condition. Food, surroundings, and health monitoring help reduce adverse effects, encouraging a smooth transition and strong breastfeeding performance.
Advanced techniques like reducing pen movements and guaranteeing enough space per Cow, implementing early disease detection and treatment protocols, and ensuring a balanced diet with the right supplements improve well-being even more during this changeover time. Early addressing of the leading infectious illnesses also helps avoid subsequent metabolic problems, emphasizing the need for thorough cow health care during the transition.
Overcoming Transition Period Challenges: From Metabolic Disorders to Effective Management
Dairy cows have a difficult transition time full of many factors that may significantly affect their health and output. Metabolic problems are among the most often occurring ones at this time. Common conditions include ketosis and fatty liver. When cows burn down too much body fat to satisfy their energy needs, ketosis results, and ketone bodies build up in the circulation. Excessive fat mobilization and triglyceride buildup in the liver cause fatty liver, impairing its regular operation.
Problems in the transition phase are typically related to nutritional imbalances. In over-conditioned cows, a typical problem is insufficient dry matter intake (DMI). One customer mentioned, for instance, that there was no milk output from high-parity cows because of inferior feed supplied during dry time. This resulted in low post-calving production and metabolic stress.
Significant management difficulties also exist. Transition success in the herd depends on its physical surroundings, dietary patterns, and social dynamics, including dominance hierarchy and social stress. For instance, a recent Mexico consultation revealed how a scarcity of crucial feed ingredients brought on by border restrictions resulted in a significant shift in cow diets, upsetting rumen function and changing milk components.
Milking frequency and the introduction of concentrates after calving are crucial. An uneven diet might arise in several European systems using automatic concentrate feeders, particularly for over-conditioned cows, and reducing the milking frequency during the first week after calving will assist in restoring their energy balance and controlling metabolic problems.
Important issues include pen motions and societal hierarchy. Giving more room and strategic feeding times, minimizing pen movements, and lowering dominating behavior will help to improve feed intake and health results. Since cattle eat as a herd, their allometric character makes it imperative to maximize these inclinations to guarantee consistent feed intake and lower stress.
Addressing metabolic diseases, guaranteeing appropriate nutrition, and controlling social and environmental elements are crucial to reducing the difficulties during the transition phase. Practical examples from several worldwide environments underscore the complexity and need for thorough management measures to maintain dairy cow health and production.
Strategic Nutritional Management to Optimize Health and Productivity in Transitioning Dairy Cows
Cow health and production depend on an appropriate diet throughout the changeover phase. The metabolic and physiological changes from dry to peak lactation require a balanced diet.
Premium forages, such as grass hay and alfalfa, are essential. These provide the required fiber to keep the rumen working and avoid problems such as displaced abomasum. In 1999, Drackley emphasized the need for fodder quality in maintaining dry matter intake (DMI).
Additionally, balanced meals that satisfy the Cow’s demands for calories, protein, and vitamins without excesses that lead to metabolic disorders are essential. Including the correct combination of proteins and carbs helps control energy balance, lower ketosis risks, and promote lactation. Research by Cook and Nordlund ( 2004) underlines the requirement of exact ration formulation in this era.
Supplements improve metabolic conditions. Essential minerals and vitamins, including calcium, magnesium, and phosphorous, help avoid hypocalcemia. Huzzey et al. (2006) claim that monensin may help lower subclinical ketosis and increase feed efficiency.
Gradual diet changes are essential. Moving gradually from high fodder to high concentrate levels lets cows adjust without metabolic stress. Strategic feeding and monitoring help avoid diseases and provide a consistent intake, which is essential for recovery after calving.
Including balanced diets, premium forages, and focused supplements creates a solid nutritional plan. During the transition phase, these methods improve cow health, lower metabolic problems, and increase output.
Mitigating Metabolic Disorders: The Cornerstone of Transition Cow Health
For dairy cows, metabolic problems during the transition phase represent major issues influencing production and general health. Three central diseases to be on alert are fatty liver syndrome, hypocalcemia, and ketosis.
When cows have a negative energy balance, ketosis results; this occurs postpartum. Low dry matter intake drives the Cow to convert fat stores into ketones. Among the signs include fatigue, a diminished appetite, and a lower milk supply. Untreated ketosis might cause severe disorders such as displaced abomasum or metritis. Bach et al. (2008) emphasize early identification and action as vital to minimize these effects.
They are known as milk fever. Hypocalcemia—low blood calcium levels around calving—results from the abrupt start of lactation. Muscle weakness, shakes, and—in extreme cases—recumbency are among the symptoms. It may compromise the immune system, increasing the likelihood of conditions such as mastitis and retained placenta. Nordlund et al. (2011) support dietary anions and calcium supplements to avoid this condition as part of nutritional plans.
Closely linked to ketosis, fatty liver syndrome results from too much fat mobilization overwhelming the liver and resulting in fat buildup. The symptoms include poor physical condition, decreased milk output, and less feed consumption. According to Drackley (1999), good management techniques help to avoid this condition by regulating energy intake throughout the dry season.
Recent studies like Caixeta et al. (2018) show the interdependence of these diseases by pointing out relationships between subclinical hypocalcemia, ketosis, and fatty liver syndrome. This implies that efficient management of transition cows depends on comprehensive strategies aimed at general metabolic health.
Managing metabolic problems during transition requires a multimodal strategy, including constant monitoring, exact dietary plans, and quick veterinarian intervention. Knowing their origins, symptoms, and effects can help dairy producers greatly enhance cow health and output.
Effective Farm Management Practices: The Pillars of Transition Period Success
Dairy cow changeover times provide particular difficulties that need good farm management techniques. Maximizing living conditions, lowering stress, and applying cutting-edge monitoring technologies to preserve cow health and output are part of a strategic strategy.
Cow health depends critically on housing. Giving enough room per Cow in transition pens—ideally, 30 inches of bed space—helps prevent subordinate cows’ displacement. Additionally, it helps to lower infections, including mastitis (Cook & Nordlund, 2004), and it is clean, dry, and comfy bedding.
Reducing stress is equally crucial. Dairy cows flourish in surroundings that allow for social activity. Minimizing pen movements during the transition time improves feed intake and lowers stress. Along with modest anti-inflammatory therapies, monitoring calving and offering appropriate support can help control stress and inflammation post-calving (Huzzey et al., 2006).
Advanced monitoring systems are crucial for the early discovery and treatment of metabolic diseases. Technologies such as activity trackers and rumination monitors detect subtle behavioral changes that indicate problems such as ketosis or hypocalcemia. Early intervention based on data-driven insights may dramatically improve results (Caixeta et al., 2018).
Including these techniques in everyday procedures offers a complete strategy to help dairy cows during the crucial transition phase. Farmers may design a setting that guarantees a seamless transition from dry Cow to peak lactation by emphasizing housing, stress management, and sophisticated monitoring.
Innovative Approaches to Managing the Transition Period in Dairy Cows
Controlling the transition phase in dairy cows calls for traditional and creative solutions to improve output and health. Modern technology, precision farming, and holistic health approaches have changed this critical stage.
Wearable health monitors tracking real-time vital indicators like body temperature and activity levels are among the most exciting developments. These devices make early diagnosis of problems like ketosis or hypocalcemia possible, permitting prompt responses (Caixeta et al., 2018). Together with automated feeding systems, they provide tailored nutrition, maximizing dry matter consumption and general health.
Using GPS and automated tools, precision farming methods guarantee correct feed and supplement delivery—qualities vital throughout the changeover time. This approach also covers barns’ environmental management, lowering stress, and raising cow wellbeing.
Holistic health management combines veterinary treatment with alternative therapies like herbal medicine and acupuncture to strengthen immunity and lower inflammation. Mild anti-inflammatory medications and appropriate calving monitoring can help significantly reduce stress after calving (Huzzey et al., 2006).
Data analytics and machine learning provide preemptive interventions by predicting possible health problems. Knowing the function of the microbiota helps create diets that avoid dysbiosis and related health issues.
Herd social dynamics are another aspect of holistic farm management. Reducing pen movements and guaranteeing enough space for each Cow at feeding stations helps to lower social stress and promote more feed intake (Nordlund et al., 2011).
Using these creative ideas helps dairy cow health and production throughout the transition time, promoting sustainability and profitability of dairy farming. Farmers may use technology developments and holistic approaches to help their herds flourish during this demanding era.
The Bottom Line
Control of the dairy cow transition time is vital. This period demands a sensible diet, knowledge of metabolic problems, and good management strategies. Prioritizing dry matter intake, customizing feed formulas, and using efficient farm management to reduce stress can assure success. Strategic nutritional planning is highlighted by research on food, consumption, and illness risk that stresses Bach et al. (2008) and Caixeta et al. (2018). As Nordlund et al. (2011, 2006) demonstrate, practices such as minimizing pen movements and giving enough feeding area improve cow welfare and the feed economy. Working together with dairy producers, vets, and nutritionists is vital. Using the most recent knowledge will help us to improve transition plans and guarantee a sustainable, profitable future for the dairy sector.

Explore effective measures to prevent heat stress in dairy calves right from their time in utero. Discover practical strategies to guarantee healthier, more productive cattle from birth through adulthood.
As summer approaches, keeping cattle cool becomes crucial for dairy producers. Often, calves aren’t prioritized in these cooling strategies. Still, the impacts of heat stress can start before birth and have lasting consequences.
Preventing heat stress begins in utero. Research shows that heat stress on pregnant cows can affect fetal development, leading to long-term issues in the calf’s health and productivity.
“Heat stress does not discriminate, and it will impact cattle of all ages and physiological states,” emphasized Jimena Laporta, an esteemed assistant professor of lactation physiology at the University of Wisconsin-Madison. Her extensive research on heat stress in cattle has been instrumental in shaping our understanding of this issue.
Understanding these impacts helps you, as dairy producers, implement strategies to mitigate heat stress from the early stages, ensuring healthier, more productive cattle. Your role in this process is vital for the animal well-being and the economic success of dairy operations.
Understanding the All-Encompassing Impact of Heat Stress on Dairy Calves
“Heat stress affects cattle of all ages and physiological states,” said Jimena Laporta, assistant professor of lactation physiology at the University of Wisconsin-Madison. Her research focuses on prenatal heat stress impacts, highlighting the last trimester of gestation as a critical developmental period.
Laporta noted, “There is increasing evidence that heat stress during these early developmental windows has long-term effects.” Her studies link in-utero heat stress to shorter gestation periods, lower birth weights, and weaker immune systems.
Jennifer Van Os, assistant professor and extension specialist in animal welfare at the University of Wisconsin-Madison, stresses the importance of heat abatement strategies for calves. “The goal is to reduce heat gain and promote heat loss,” Van Os stated.
Van Os recommends elevating hutches and adding extra windows for better ventilation. “When housed in pairs, two calves generate more heat,” she explained, emphasizing the need for adequate ventilation.
Laporta and Van Os’s research at the University of Wisconsin-Madison provides a comprehensive view of heat stress in calves, from prenatal to post-birth. Their findings underscore the persistent impacts of heat stress, making preventive measures essential for herd welfare and productivity.
The Crucial Window: Understanding the Impact of Maternal Heat Stress in the Last Trimester of Gestation
The last trimester of gestation is critical for fetal development. The fetus grows and matures during this period, making it highly sensitive to temperature. Maternal heat stress inevitably leads to prenatal heat stress because the fetus relies on the mother for temperature regulation. This can significantly impact fetal development.
Key physiological processes like organ maturation and cell differentiation are particularly vulnerable. If exposed to high temperatures, organs such as the liver, lungs, and kidneys may not develop properly, leading to long-term deficits.
Heat stress can also disrupt cell hierarchy and communication, which is essential for healthy development. Cells may not differentiate correctly, compromising tissues and systems. Additionally, thermal stress can impede cell proliferation, resulting in smaller organs and tissues.
In essence, maternal heat stress means developmental setbacks for the fetus, affecting its health and productivity later in life. Addressing heat stress during this period is crucial for the future well-being of calves.
Revealing the Long-Lasting Consequences of Maternal Heat Stress: Insights from Florida and Wisconsin
Laporta’s studies in Florida and Wisconsin uncovered key findings on maternal heat stress. Calves born to heat-stressed cows had shorter gestation lengths by five days, leading to lighter birth weights (around 10 pounds less). These calves also had a reduced ability to absorb immunoglobulins from colostrum, weakening their immune systems. Furthermore, their overall growth was hindered, with these calves remaining smaller across various dimensions, even after one year, compared to calves from cooled cows.
These calves usually have reduced body size, with shorter body length, chest girth, hip height, and trimmer head circumference, which affects their overall health and productivity.
Another critical consequence is reduced milk production. Calves stressed in utero have compromised mammary gland development, resulting in lower milk yields across multiple lactations. While they manage around 65 pounds of milk during their first lactation, their cooled counterparts significantly outperform them. Heat-stressed heifers produce less milk and have a reduced productive lifespan of about 12 months.
These enduring effects highlight the potential benefits of addressing heat stress early. By mitigating prenatal heat stress, you, as dairy producers, can ensure better growth, improved milk production, and longer productive lifespans for your cattle. This can lead to more efficient and profitable farming operations.
Essential Strategies for Mitigating Heat Stress in Calves Both In Utero and Post-Birth
Mitigating heat stress in calves, starting from the womb, is critical to their health and productivity. Ensure pregnant cows stay cool with shade, fans, and soakers to minimize in-utero heat stress.
After birth, keep calves comfortable:
Better Ventilation: Elevate hutches on cinder blocks or stands to improve airflow and keep the space cooler.
Provide Shade: To reduce heat, use shade cloths that block 80% of sunlight and place hutches under trees or covered areas.
Use Fans: In barns, fans and positive pressure tubes can create airflow, calm calves, and refresh the air.
Remember, as dairy producers, you have the ability to significantly reduce heat stress and improve your calves’ long-term health and productivity by implementing these strategies.
The Bottom Line
Addressing heat stress in calves from the prenatal stage is vital for their long-term health and productivity.

At the start of 2024, the EU saw a significant change in its dairy industry: dairy cows dropped below 20 million, hitting 19.7 million. This marks a historic low and indicates a continuing downward trend in cow numbers, which is expected to persist throughout the year.
The Double-Edged Sword of Rising Cow Productivity Amid Shrinking Herds
Even though each cow produces more milk, more is needed to make up for the overall decline in cow numbers across the EU. Simply put, fewer cows mean less milk overall. This imbalance contributes directly to the forecasted 0.3% drop in milk production for 2024. Despite individual productivity gains, the milk output is declining due to the shrinking herds.
A Temporary Respite: Early 2024 Sees Milk Deliveries Surge Before Expected Decline
Early 2024 saw a 1.7% rise in cow’s milk deliveries compared to the same period in 2023. However, this boost is short-lived. Many farmers are expected to sell their cows or exit milk production later in the year, leading to a decline in deliveries.
The Multifaceted Challenges Shaping Europe’s Dairy Economy
The economic landscape for dairy farmers is becoming more challenging. A key issue is the steady drop in farm-gate milk prices since early 2023, significantly affecting profitability.
Production Costs: High production costs for energy, fertilizers, and labor persist, squeezing farmers’ margins despite some recent reductions.
Geographical Impact: In Germany, France, Poland, and Belgium, smaller and less efficient farms are hardest hit. The pressure from lower milk prices and high input costs drives many to reduce herd sizes or stop milk production.
Environmental Regulations: Environmental rules in the Netherlands and Ireland seek to cut nitrogen emissions, which are expected to negatively affect herd numbers and production costs in the long term.
Overall, larger farms may better cope, but the trend toward consolidation continues due to falling profits and rising costs.
Environmental Regulations Cast Long Shadows Over EU Dairy Farming
Environmental regulations are threatening Europe’s dairy farming. New measures to curb nitrogen emissions are adding pressure on struggling farmers in the Netherlands and Ireland.
For example, the Netherlands aims to cut nitrogen emissions by 50% by 2030, including reducing the number of dairy cows and relocating farms. Ireland’s targets similarly demand stricter manure management and sustainable farming practices, both costly and complex.
These regulations, combined with high production costs and declining milk prices, make it challenging for smaller farms to stay in business. Many are choosing to exit the market rather than invest in expensive upgrades.
As a result, smaller farms are shutting down, and larger farms need help to maintain their herd sizes. Although these regulations are essential for a greener future, they add another layer of complexity to the EU dairy industry’s challenges.
Generation Renewal Crisis Accelerates Market Consolidation in EU Dairy Sector
A growing trend in market consolidation and farm closures is evident within the EU dairy sector. One key issue here is the challenge of generation renewal. Younger generations are increasingly hesitant to continue milk production due to the heavy workload and tight profit margins. Elevated production costs and decreasing farm-gate milk prices also make it challenging for smaller, less efficient farms to stay in business.
However, larger and more professional farms show notable resilience. They often have better infrastructure, access to advanced technology, and excellent financial stability, allowing them to maintain herd numbers despite broader declines. By leveraging economies of scale and more efficient practices, these farms can better absorb economic shocks and comply with environmental regulations.
This disparity between small and large farms is accelerating market consolidation. As smaller farms exit, larger ones are absorbing their market share. While the total number of dairy farms is decreasing, those that remain are becoming more advanced and better equipped to tackle future challenges in the dairy economy.
Record-High Milk Prices in 2022 Spark Production Surge, Only to Shatter in 2023-2024
The surge in milk deliveries in 2022 and 2023 stemmed from record-high EU farm gate milk prices in 2022, peaking in December. These prices incentivized farmers to boost production despite rising costs, supporting the dairy industry at that time.
However, these prices began to fall from May 2023 through March 2024, squeezing farmers financially. Although still above the 5-year average, the decline sharply contrasted with 2022’s profitability. With global milk production up and dairy demand fluctuating, EU farmers adjusted their production levels, paving the way for a predicted drop in milk deliveries in 2024.
The Ripple Effect: How Global Market Dynamics Shape EU Milk Prices
Global market dynamics significantly impact EU milk prices. The world’s largest dairy exporters, including Australia, the United States, the UK, and New Zealand, have increased production, leading to an oversupply that pressures prices downward. This makes it challenging for EU producers to maintain their margins.
Simultaneously, demand from major importers like China and some Middle Eastern countries is declining. Various factors, including trade tensions and shifting consumer preferences, contribute to this weaker demand.
This supply-demand imbalance has reduced farm gate milk prices in the EU. While European prices remain higher than those of international competitors, more than this advantage is needed to counteract the rising production costs and reduce global demand. The EU dairy industry must navigate these challenges to stay competitive and sustainable.
Price Disparities in Global Dairy: EU’s Costly Position Against New Zealand and US Competitors
When you look at milk prices, you’ll notice that the EU’s are much higher than those of other major exporters like New Zealand and the US. In February 2024, the EU’s milk price hit EUR 46.42 per 100 kilograms. That’s 27% more than New Zealand’s and 18% more than the US.
These higher prices mean EU dairy products cost more to produce and sell, making it challenging for EU producers to compete globally. Higher costs can squeeze farmers further, especially with high input costs and changing demand.
Weather Woes: Uneven Conditions Across Europe Impact Dairy Farming
In 2024, weather was vital in shaping feed and pasture conditions across Europe. Spring brought warm temperatures and balanced rainfall, leading to good green feed availability. However, the northwest, especially Ireland, faced challenges. Ireland’s dairy farming, which relies on cattle grazing for up to nine months, has struggled with wet soils and recent rains. These conditions hindered field access and grassland regrowth, severely impacting milk production.
The Bottom Line
In summary, EU milk deliveries are forecast to dip to 144.8 million metric tons (MMT) in 2024. Unfavorable weather and high input costs for energy and fertilizers are straining farmer margins. Despite brief boosts in productivity, these challenges will likely persist throughout the year.
Key Takeaways:
Decline in Cow Numbers: Cow numbers fell below 20 million for the first time in early 2024, indicating a continuing downward trend.
Productivity vs. Herd Size: Increased productivity per cow is not enough to counterbalance the overall decrease in herd sizes.
Initial Surge in Milk Deliveries: Early 2024 saw a 1.7% increase in milk deliveries, but this is expected to decline as more farmers exit the industry.
Decreasing Profitability: Farm-gate milk prices have been falling since early 2023, alongside high production costs, squeezing farmers’ profit margins.
Impact of Environmental Regulations: Government plans to cut nitrogen emissions in countries like the Netherlands and Ireland are affecting herd numbers.
Market Consolidation: The industry is seeing greater consolidation, with smaller, less efficient farms closing and bigger farms maintaining their herd sizes.
Weather Complications: Varying weather conditions across Europe in 2024 have impacted green feed availability and pasture conditions, particularly in Ireland.
Summary: The European Union’s milk production is experiencing a significant decline, with a predicted 0.3% drop in cow milk production. This decline is attributed to rising production costs and lower farm-gate milk prices. The number of dairy cows has fallen below 20 million for the first time, making milk production less profitable for EU farmers. In early 2024, there was a 1.7% rise in cow milk deliveries compared to the same period in 2023, but this was short-lived as many farmers were expected to sell their cows or exit milk production later in the year. The economic landscape for dairy farmers is becoming more challenging, with a steady drop in farm-gate milk prices since early 2023 significantly affecting profitability. High production costs for energy, fertilizers, and labor persist, squeezing farmers’ margins despite some recent reductions.

Confronting the Invisible Foe: Tackling Mycotoxins for Healthier Herds and Safer Milk
Mycotoxins—toxins from mold in feed—threaten livestock health and milk safety in dairy farming. Common mycotoxins like aflatoxins (AFB1), deoxynivalenol (DON), fumonisins (FUM), T-2 toxin, and zearalenone (ZEN) can harm dairy cows by affecting liver function, immunity, and overall productivity. These toxins can enter milk, posing risks to human health.
Anti-mycotoxin feed additives such as Hydrated Sodium Calcium Aluminosilicate (HSCA) and Mycotoxin Deactivators (MD15 and MD30) have been developed to combat these dangers. These additives bind or transform mycotoxins, making them less absorbable and reducing their levels in the cow’s system. This study examines these additives’ effectiveness by measuring mycotoxin levels in milk, urine, and blood plasma, ensuring they don’t harm cow performance or nutrient absorption.
Let’s delve into the essence of the research. This study was meticulously conducted, involving twelve carefully selected multiparous cows. These cows, averaging 165 days in milk, 557 kg in body weight, and an initial milk yield of 32.1 kg/day, were grouped based on parity, milk yield, and days in milk. They were then assigned to a 4 × 4 Latin square design over 21-day periods, with the last seven days dedicated to data collection. This rigorous methodology ensures the reliability and applicability of the study’s findings to real-world dairy farming scenarios.
The cows received different treatments to test the anti-mycotoxin feed additives:
Mycotoxin group (MTX): Basal diet (BD) without additives.
Hydrated sodium calcium aluminosilicate (HSCA): BD plus 25g/cow/day.
Mycotoxin deactivator 15 (MD15): BD plus 15g/cow/day of Mycofix® Plus.
Mycotoxin deactivator 30 (MD30): BD plus 30g/cow/day of Mycofix® Plus.
All cows were exposed to a mycotoxin blend, including 404 μg aflatoxins B1 (AFB1), 5,025 μg deoxynivalenol (DON), 8,046 μg fumonisins (FUM), 195 μg T2 toxin (T2), and 2,034 μg zearalenone (ZEN) for the last seven days of each period.
This setup allowed the researchers to evaluate the effects of each treatment on mycotoxin levels in milk, urine, and blood, as well as the cows’ overall performance and health.

Unlock fertility in Holstein cattle: How does genomic daughter pregnancy rate impact postpartum estrous behavior? Discover the key to better reproductive management.
In the context of Holstein cattle, the postpartum transition period is a pivotal phase that sets the stage for successful dairy farming. This period, which spans the first three weeks after calving, is a critical time when cows are particularly vulnerable to health issues that can significantly impact their fertility and productivity.
Health complications like retained placenta, ketosis, and displaced abomasum can reduce milk production and disrupt the metabolic balance, affecting the cow’s return to estrous behavior and timely conception.
Early estrous resumption within the voluntary waiting period (VWP) signals good reproductive health, leading to shorter calving intervals and better fertility outcomes. Key benefits include:
Improved milk production
Fewer metabolic disorders
Higher reproductive success
Understanding these factors is not just informative, but it also empowers dairy farmers to make informed decisions . By implementing these strategies, you can optimize herd health and reproduction, playing a crucial role in the success of your dairy farm.
Overcoming the Energy Deficit: Navigating the Transition Period in Dairy Cows
The transition period for dairy cows is full of challenges due to the energy deficit they experience. As cows ramp up milk production, their energy intake often falls short, leading to metabolic disorders like ketosis. This imbalance not only affects their health but also their reproductive performance.
Energy-deficient cows are more likely to face anovulation, where the ovaries do not release an egg, leading to longer calving intervals and delayed conception. This delay decreases fertility rates and reduces the profitability of dairy farms. Early resumption of estrous cycles within the voluntary waiting period (VWP) is critical for better reproductive outcomes.
Monitoring early postpartum cows is a crucial aspect of reproductive management. While methods like transrectal ultrasound or blood progesterone concentration can identify anovulatory cows, they can be resource-intensive. In contrast, automated activity monitoring systems present a more efficient and effective alternative. These systems track estrous activity and provide timely alerts for cows with poor reproductive performance, thereby enhancing the overall efficiency of reproductive management.
By understanding the impact of negative energy balance and effectively monitoring postpartum cows, you can boost your dairy farm’s reproductive performance. This assurance is backed by scientific evidence, enhancing your confidence in these strategies and their potential to increase productivity and profitability.
Utilizing Technology to Identify Anovulatory Cows Efficiently
Identifying anovulatory cows is essential for better reproductive outcomes. Traditional methods like transrectal ultrasound and progesterone tests are effective but time-consuming. Ultrasound directly visualizes corpus lutea, while progesterone tests confirm ovulation through hormone levels.
Automated activity monitors are revolutionizing estrus detection. These systems use sensors to track changes in activity, signaling when a cow is in heat. By continuously measuring activity levels, these devices help accurately and timely identify the best breeding times. They can also alert you to health issues early by detecting deviations in regular activity.
Automated monitors reduce the labor needed for estrus detection and enhance reproductive management withoutmanual effort. They replace traditional methods like tail paint or watching for mounting behavior, which are time-consuming and often require multiple daily checks.
Harnessing GDPR for Enhanced Reproductive Efficiency in Dairy Cattle
GDPR, or genomic daughter pregnancy rate, measures the likelihood of a bull’s daughter getting pregnant. This metric helps breeders choose bulls to enhance reproductive efficiency.
GDPR is significant in predicting fertility. It helps farmers select bulls whose daughters conceive more efficiently, reducing calving intervals and boosting herd productivity. This is vital for maintaining optimal milk production and farm profitability.
Advancements in genetic technologies, like single nucleotide polymorphism (SNP) platforms, have improved GDPR accuracy. These tools provide precise insights into genetic profiles affecting fertility.
By integrating GDPR into breeding programs, farmers can identify high-fertility heifers and cows early. This proactive approach aligns with targeted reproductive management, boosting reproductive performance, reducing pregnancy loss, and increasing profitability.
Diving into the Data: Analyzing 4,119 Lactations to Unveil GDPR’s Impact on Estrous Activity
The study analyzed 4,119 lactations from 2,602 Holstein cows to uncover the link between genomic daughter pregnancy rate (GDPR) and postpartum estrous activity. Hair samples were collected from the tail switch of each cow around two months old. These samples were genotyped with a single nucleotide polymorphism (SNP) platform to estimate GDPR.
Each first-calving cow wore a neck-mounted activity monitor, which recorded continuous activity and detected estrous events from seven to 30 days in milk (DIM). We measured estrous intensity (maximum activity level) and Duration (hours from start to end of estrus).
Farm staff examined postpartum cows daily until 10 DIM. Calvings were classified as assisted, forced extraction, or unassisted. Health issues like retained placenta, ketosis, and left displaced abomasum were also logged, giving us a thorough view of each cow’s health and its effect on estrous activity.

The study revealed intriguing insights into the link between GDPR and estrous activity. Cows with higher GDPR showed higher intensity and longer Duration of estrous expression. This pattern was consistent across various lactation stages, proving GDPR’s value as a predictive marker.
In the study window of seven to 30 days in milk (DIM), 41.2% of cows resumed estrous activity. Specifically, 31% had one event, 10.2% had two or more events, and 58.8% showed no estrous signs.
First-lactation cows were more likely to resume estrous activity than older cows, suggesting a quicker postpartum recovery in younger cows.
Health issues like assisted or unassisted calving, retained placenta, or left displaced abomasum didn’t significantly affect estrous activity. However, ketosis reduced the frequency of estrous alerts. Moreover, the combination of ketosis and GDPR emphasized how metabolic health impacts reproductive performance.
The study highlights GDPR’s potential as a genetic and practical tool for better reproductive management. Cows with higher GDPR were likelier to show early, intense, and prolonged estrus, making this trait valuable for boosting herd fertility and productivity.
Genomic Merit vs. Metabolic Challenges: Understanding Ketosis and Estrous Activity
Health disorders like ketosis, which arises from severe negative energy balance, can significantly impact estrous activity in dairy cows. Ketosis is particularly detrimental. Cows suffering from ketosis often exhibit fewer estrous alerts postpartum, indicating impaired reproductive function. This reduced activity underscores the importance of addressing metabolic health to improve fertility outcomes.
Interestingly, the interaction between ketosis and genomic daughter pregnancy rate (GDPR) sheds light on potential genetic influences on estrous behavior in the presence of health disorders. Data shows that cows with higher GDPR are more likely to exhibit estrous activity early postpartum, even if they experience ketosis. This suggests that genomic merit for fertility can partially mitigate the adverse effects of metabolic disorders on reproductive performance.
In essence, while ketosis poses a significant barrier to resuming regular estrous cycles, leveraging high GDPR can offer a genetic advantage. By focusing on improving GDPR, dairy farmers can enhance reproductive success despite common health challenges during the transition period.

This suggests that immediate milk abundance might be quickly offset by long-term supply constraints.
Bird Flu, Heifer Shortage, and Herd Dynamics Pose Multifaceted Challenges for 2024 Milk Production
The dairy industry is grappling with several critical issues that could disrupt milk production for the rest of the year. Key among these is the persistent bird flu, which continues to affect herds in major milk-producing states like Idaho and Michigan and is now spreading into the Northern Plains.
Compounding the problem is the ongoing heifer shortage. Dairy producers are finding it increasingly difficult to keep their barns and bulk tanks full due to limited availability of replacement heifers. The high demand has driven up prices, leading some producers to sell any extra heifers they have, though this only temporarily eases the shortage.
At the same time, dairy cow slaughter volumes have plummeted as producers retain low-production milk cows to maintain or grow herd sizes. While this strategy aims to increase milk output, it involves keeping less efficient cows longer, which could hinder overall growth. These challenges together create an uncertain outlook for milk production in the months ahead.
Intermittent sunshine gave farmers just enough time to catch up with the average corn planting pace. As they dodge showers and storms, some in fringe areas may switch crops, while others might opt for prevented planting insurance rather than risk fields for sub-$5 corn. The trade remains cautious, gauging the wet spring’s impact on yield and acreage. However, the moisture might be welcome as we approach a potentially hot, dry La Niña summer. Consequently, July corn futures dropped nearly 20ȼ to $4.46 per bushel, and soybean meal plummeted $21 to $364.70 per ton.
The Bottom Line
This week, the dairy market experienced significant shifts, with butter prices dropping sharply before partially recovering, reflecting ongoing volatility. Cheese prices also declined, although strong domestic demand and exports helped stabilize the market. Interestingly, whey prices bucked the trend, driven by robust demand for high-protein products.

Unlock essential strategies for aiding dairy cows in their recovery from avian influenza. Learn how to restore peak milk production and safeguard against subsequent health challenges. Explore the insights now.
The recent avian influenza outbreak has presented unexpected challenges to the dairy industry, a sector not typically associated with such diseases. However, dairy producers have shown remarkable resilience in the face of these unprecedented implications. While avian influenza is primarily known for its impact on poultry, its effects on dairy cows have introduced a new set of concerns that are reshaping farm management strategies. The effects are complex and multifaceted, from notable drops in milk production to potential health risks in cows.
“It’s been a wake-up call for many of us in the dairy business,” says one producer. “We’ve never dealt with something this unusual, and the road to recovery is still uncertain.”
Dairy producers must swiftly adapt to mitigate the virus’s adverse effects. The immediate challenges include significant milk loss, altered feeding strategies, and potential long-term impacts on cow health. It’s clear that the path to recovery will demand not just ordinary, but extraordinary efforts and innovative approaches.
Visualizing the Avian Flu’s Toll: A Sharp Decline and a Gradual Recovery in Milk Production
The impact on milk production was immediate and profound, particularly on an individual cow basis. The lactation curve, a crucial aspect of dairy science, vividly demonstrated these changes. We observed a significant drop in daily milk weights when avian influenza struck. This dramatic reduction was a stark deviation from the expected yields.
Monthly milk tests highlighted the severity of this impact. Instead of a steady rise or predictable plateau, the curves showed a pronounced downturn post-infection, underscoring the virus’s strong effect on milk production.
Continuing to graph these metrics for our clients, we captured both the disruption and gradual recovery. The recovery phase, while encouraging, raised questions about the long-term implications on overall production and the cows’ full lactation potential. The curves showed a slow climb back to pre-infection yields, but complete restoration remained uncertain.
Recovery Trends: Each Cow’s Unique Journey Amidst Herd-wide Recovery
Recovery trends in milk production have revealed unique stories for each cow and the herd. Initially, avian influenza led to a consistent drop in milk output, which was evident in daily weights and monthly tests. While herd averages are recovering toward pre-infection levels, the individual stories are more complex.
Graphing energy-corrected milk per cow shows dramatic declines followed by gradual recoveries post-infection. Still, not all cows return to their former projections. Early lactation cows show more robust recoveries, while those in later stages may sustain reduced production until dry-off. Expectations based on historical lactation curves need adjustment.
Comparing individual recovery to herd averages shows that while overall productivity can bounce back, some cows might still need to regain peak performance. Mapped against averages or historical curves, individual daily production often needs to catch up.
In conclusion, aggregate data gives an optimistic view, but individual focuses reveal varied influenza impacts. The path to pre-infection production levels is uneven. Tailored management and nutrition are crucial for each cow’s recovery.
Feeding Strategies for Recovery and Long-term Health Post-Avian Influenza
Feeding strategies should prioritize immediate recovery and long-term health due to the sharp decline in milk production from avian influenza. A multifaceted approach that includes targeted nutritional adjustments and vigilant monitoring is not just essential, but also effective in ensuring a successful recovery and long-term health for the cows.
One effective strategy is increasing the energy density of the diet using high-quality forages and grains to prevent over-conditioning, particularly in late-lactation cows.
Enhanced protein supplementation is crucial. Adding sources like soybean meal or canola meal supports milk synthesis and recovery.
Incorporating rumen-protected fats can provide concentrated energy, improving overall energy status and supporting milk yield without risking acidosis.
Monitoring and adjusting vitamin and mineral intake is vital. Including B vitamins, selenium, vitamin E, zinc, and copper enhances immune function and recovery.
Focusing on feeder consistency and cow comfort is essential. Ensuring consistent feed delivery times, fresh feed availability, and a stress-free environment supports health and production.
Monitoring tools like body condition scoring and precision feeding technologies can help fine-tune diets to meet individual cow needs effectively.
Collaborating with veterinarians and nutritionists to develop tailored feeding plans ensures that nutritional strategies fit the herd’s current status and address potential future challenges.
A holistic and adaptive approach with strategic feeding interventions can significantly support cows in regaining production levels and securing overall health. Each cow’s recovery is a crucial part of the overall herd’s recovery, emphasizing the importance of individual cow care in the process.
Individual Cow Variability in Recovery Post-Avian Influenza: Factors Influencing the Path to Normalcy
Individual cow variability in recovery after avian influenza is significant. Factors such as age, lactation stage, and days in milk play critical roles in how each cow recovers. Younger cows, like first-lactation heifers, often rebound quicker due to higher resilience. Older cows might struggle more, incredibly late in lactation, as their metabolic reserves are less adaptive.
The stage of lactation at infection is crucial. Cows in early lactation might see a notable drop in peak milk yields but can recover better than those in mid to late lactation. Cows infected late in lactation may maintain reduced milk levels until dry-off, risking over-conditioning as they might continue eating the same amount of feed despite lower production.
Days in milk (DIM) also affects recovery. Cows with fewer DIMs have more time to recuperate. At the same time, those nearing the end of their lactation cycle face a limited recovery window, increasing the chance of persistent production deficits.
Careful monitoring and tailored management strategies are essential to support each cow’s recovery. Tracking individual recovery patterns, alongside broader herd trends, is crucial for optimizing post-influenza recovery plans and ensuring long-term herd health and productivity.
Navigating the Risks: Over-Conditioning Concerns and Reproductive Challenges Post-Avian Influenza
The concern is that cows that saw a significant drop in milk are more likely to gain too much weight during the rest of their lactation. They will produce less milk than usual, and the question is, will they also eat less? If not, they might gain extra weight, risking problems when they start lactating again. It’s essential to watch late lactation cows’ body condition and be ready to act. We might be unable to plan for this since the number of cows affected may not justify a diet change, but it’s worth considering. Breeding was also hit during the illness, so some cows will milk longer due to slower breeding, increasing the risk of gaining too much weight.
Balancing Act: Mitigating Over-Conditioning Risks and Ensuring Smooth Transitions in Post-Avian Influenza Dairy Herds
The concern is that cows that experience a significant drop in milk are at higher risk of over-conditioning. They will produce less milk, and there’s a question of whether they will eat less to match. If not, they might gain extra body condition, risking transition issues in their next lactation. It’s crucial to monitor body condition in late lactation and adjust accordingly. Affected cows may not merit a diet change, but this shouldn’t be ruled out. Reproduction has also suffered, leading to some cows milking longer and increasing the risk of over-conditioning.
Additionally, cows dried off early due to milk loss need special attention. This may necessitate a low-energy dry cow pen, as drying off early can lead to significant transition issues at calving. Proper management of these cows is vital. Although it may sound unconventional, limiting feeding a far-off dry cow ration—with enough bunk space and a bulky mix—can be effective.
Avian Influenza’s Impact on Fertility: Navigating Delayed Breeding and Prolonged Lactation Periods
Reproductive success suffered during the avian influenza outbreaks. Ill cows faced compromised health and fertility, delaying breeding schedules and extending lactation periods. Cows expected to dry off continued milking due to unsuccessful breeding, increasing their risk of over-conditioning.
Extended lactation and reduced milk yield can lead to excess body condition if cows consume more feed than needed. Over-conditioning poses health risks, especially during the transition to the next lactation cycle. Over-conditioned cows are more prone to metabolic disorders like ketosis and fatty liver, complicating their ability to conceive and maintain pregnancies.
Close monitoring and adjustments in feeding strategy are essential. Regular body condition scoring and tailored nutrition plans can help mitigate over-conditioning risks, ensuring cows are in optimal shape for their subsequent reproductive cycles.
The Bottom Line
The recent avian influenza outbreak has significantly affected dairy production, marked by a sharp decline and gradual recovery in milk output on both individual and herd levels. Each cow’s recovery path highlights the need for targeted feeding strategies and close monitoring to prevent over-conditioning and ensure a smooth transition into the next lactation. Addressing reproductive challenges due to delayed breeding is also crucial for long-term herd health. Thus, continuous vigilance and adaptive management practices are vital for supporting dairy cows, safeguarding their health, and maintaining productivity.
Key takeaways:
The avian influenza outbreak caused a marked drop in daily and monthly milk production, with varying recovery rates among individual cows.
Graphing milk production curves revealed dramatic declines during infection, with recovery trends differing based on cows’ lactation stages.
Feeding strategies must be carefully considered to prevent over-conditioning and support sustained recovery, especially in late-lactation cows.

Delve into the influence of housing systems on digital dermatitis in dairy cows. Could genetic evaluations pave the way for enhanced bovine health across varied living conditions? Uncover the research insights here.
Imagine walking barefoot on gravel daily; the discomfort of digital dermatitis (DD) in dairy cows feels similar. This painful hoof disease significantly hampers cows’ mobility, milk production, and the economic health of dairy farms.
The environment in which cows are housed plays a critical role in DD’s incidence and severity. Housing systems such as conventional cubicle barns (CON) and compost-bedded pack barns (CBPB) have distinct impacts on disease management. Understanding these housing-related nuances is vital for farmers and researchers working to reduce DD’s impact.
This research utilizes detailed phenotyping data from over 2,980 observations of Holstein-Friesian and Fleckvieh-Simmental cows on ten farms. It investigates the genetic variances linked to DD stages: sick, acute, and chronic. Through genome-wide association studies (GWAS), the study identifies potential candidate genes and assesses genotype × housing system interactions. This comprehensive analysis seeks to uncover genetic factors that can inform breeding programs and enhance animal welfare, regardless of their rearing environment.
Introduction: Understanding Digital Dermatitis in Dairy Cows
Digital Dermatitis (DD) is an infectious disease impacting the bovine foot, particularly the plantar skin bordering the interdigital cleft. This condition ranges from initial lesions to chronic, painful wounds, affecting dairy cows‘ mobility and well-being.
The development of DD involves a mix of environmental, genetic, and management factors. Housing systems, especially conventional cubicle barns, create conditions ripe for DD, with moisture and contamination fostering pathogen growth. Nutritional imbalances, poor foot hygiene, and milking routines further increase risk. Notably, genetic predispositions also play a role; some cattle lines are more susceptible, emphasizing the need for genetic research to combat DD.
The economic and welfare impacts of DD are significant. Economically, it causes losses through reduced milk production, higher veterinary costs, and culling of severely affected cows. Welfare-wise, the pain and lameness from DD seriously affect cattle comfort and health, raising ethical concerns in livestock management. Therefore, addressing DD with better housing, management practices, and genetic selection is crucial for sustainable dairy farming.
Exploring Housing Systems: Cubicle Barns vs. Compost-Bedded Pack Barns
Housing systems play a pivotal role in dairy productivity and cow health and welfare. The primary systems include conventional cubicle barns (CON) and compost-bedded pack barns (CBPB), each impacting the Prevalence and severity of digital dermatitis (DD).
In CON setups, cows rest on mats or mattresses over concrete floors. This controlled environment supports restful ruminating but can worsen claw disorders due to constant exposure to manure and poor ventilation. Conversely, CBPB systems offer cows a spacious environment with composting bedding of sawdust or wood shavings, which is more comfortable and supports better hoof health by reducing pathogens through microbial activity.
The flooring material is crucial. Concrete floors in CON systems retain moisture and manure, fostering bacteria that cause DD. CBPB systems’ drier, more sanitary bedding leads to fewer DD incidences.
Hygiene practices, essential for DD control, differ by system. CON systems require regular scraping and washing, while CBPB systems depend on managing bedding moisture and microbial activity. Both approaches aim to reduce bacterial loads and curb DD spread.
Cow comfort, dictated by the housing system, also affects DD prevalence. CBPB’s spacious, free-roaming environment reduces stress and improves immune function, making cows less prone to DD. In contrast, CON systems’ restrictiveness can increase anxiety and susceptibility to claw disorders.
In summary, the choice between cubicle barns and compost-bedded pack barns significantly impacts cow health and the incidence of DD. Prioritizing comfort and hygiene in housing systems leads to healthier, more productive cows with fewer claw disorders.

Uncover the potential of genomic and phenotypic insights to enhance dry matter intake management in US Holstein cows, ultimately boosting milk production and body weight management. Intrigued by the possibilities?
In the context of dairy farming, ‘dry matter intake’ (DMI) is not just a term for veterinarians and nutritionists. It’s a crucial factor for US Holstein cows, the key players in milk production. The efficiency of these cows is directly linked to what they eat, how much they eat, and how effectively they convert that intake into milk and robust health. Therefore, understanding DMI is not just important for maximizing farm potential, but it’s also the key to connecting feed efficiency, milk production, and overall animal welfare.
“Optimizing dry matter intake is crucial for enhancing milk yield and ensuring cow health. It’s the linchpin of dairy farm efficiency.”
This article explores the genomic and phenotypic impacts of DMI, highlighting its role in milk production and body weight management. Using data from 8,513 lactations of 6,621 Holstein cows, we’ll examine:
The link between DMI and milk components like fat and protein.
How body size traits affect DMI.
The impact on breeding programs aiming for better feed efficiency and productivity.
Join us as we dive into these dynamics and discover strategies to boost profitability and sustainability in dairy farming.
Unveiling the Genomic and Phenotypic Dynamics of Dry Matter Intake in Holstein Cows
Understanding dry matter intake (DMI) in Holstein cows is crucial for nutrition management and breeding programs. Large data sets have revolutionized this research, allowing precise estimation of feed requirements for milk production and body maintenance. These datasets provide a strong foundation for refining predictive models.
Two main approaches are used to evaluate DMI: phenotypic and genetic regressions. Phenotypic regressions use visible traits and help dairy farmers adjust feeding strategies based on real-time data for milk yield, fat, and protein content. This is vital for optimizing feed efficiency and maintaining herd health.
Genetic regressions, on the other hand, examine the genetic factors influencing DMI. These are especially useful in breeding programs that aim to enhance important traits through selective breeding. Genetic evaluations guide breeding decisions that promote traits like higher milk yield, better milk quality, and improved feed efficiency.
The difference between phenotypic and genetic regressions highlights the distinct goals of nutrition management and genetic improvement. Phenotypic data meets immediate needs, while genetic data fosters long-term improvements. Combining both approaches enhances current and future herd performance.
These advancements in genomic tools and statistical models, such as BostaurusUMD3.1.1 for genomic evaluations, underscore the collaborative effort to advance DMI research. This collective endeavor aims to optimize productivity and sustainability in dairy farming, a goal we all share in the scientific community.
An Unprecedented Dive into Dry Matter Intake Through Genomic and Phenotypic Lenses
This study makes a unique contribution to the field of dairy farming and genetics by analyzing DMI using a large dataset from 8,513 lactations across 6,621 Holstein cows. By integrating phenotypic and genomic views, we were able to provide a detailed look at DMI through sophisticated mixed models. These models included variables like days in milk, age parity, trial dates, management groups, and body weight changes during 28—and 42-day feeding trials in mid-lactation, ensuring accuracy in the results.
Based on observable traits, phenotypic regressions gave practical insights for nutritional management. In contrast, genomic regressions, grounded in genetic data, offered deeper insights crucial for breeding programs. Both evaluation types provided a comprehensive understanding of feed efficiency and milk production potential, aiding in better selection and breeding strategies.
Balancing Nutritional Demands: Insights from Phenotypic and Genomic Regressions
The phenotypic regressions of Dry Matter Intake (DMI) on milk, fat, and protein revealed specific coefficients that underscore the intricate balance required in nutrition management. For milk, the coefficient was modest (0.014 ± 0.006), indicating a relatively low increase in DMI per unit increase in milk production. Conversely, fat (3.06 ± 0.01) and protein (4.79 ± 0.25) showed more substantial coefficients, demonstrating that increases in these components significantly elevate the DMI requirements. These results suggest that nutritional plans must be meticulously tailored, focusing more on the feed requirements for fat and protein production to ensure optimal energy balance and animal health.
When we compare these findings to the corresponding genomic regressions, we observe stark contrasts. Genomic regressions yielded higher coefficients across all components: milk (0.08 ± 0.03), fat (11.30 ± 0.47), and protein (9.35 ± 0.87). This difference implies that genetic potential is more dominant in determining feed efficiency than phenotypic observations alone. Simply put, cows with higher genetic predispositions for milk components require substantially more feed, reflecting their superior production capabilities.
These discrepancies highlight an essential consideration for breeding programs. While phenotypic data provide valuable insights into immediate nutritional needs, genomic data offer a more comprehensive forecast for long-term feed efficiency and production potential. Consequently, integrating these genomic insights into breeding strategies can drive advancements in producing more feed-efficient cows, aligning with evolving economic and environmental objectives.
The ECM Formula: Unveiling the Energy Dynamics in Dairy Production
The ECM formula is vital for measuring milk’s energy content by considering its fat, protein, and lactose components. This standardization allows for fair comparisons across various milk types. Our study uses the ECM formula to reveal the energy needs of different milk components, shedding light on the nutritional and economic facets of dairy farming.
Regarding DMI for fat and protein, phenotypic and genomic regressions show significant differences. Phenotypic regressions suggest protein production needs 56% more DMI than fat. Genomic regressions show a smaller gap, with protein needing 21% more DMI than fat. Sire genomic regressions add complexity, indicating fat requires 35% more DMI than protein. These differences highlight the challenge of converting genetic data into practical feed efficiency.
These findings have profound implications for feed cost management. Increased DMI for any milk component escalates feed expenses, a critical consideration for farmers aiming to enhance profitability. However, breeders can leverage genomic data to select cows with lower residual feed intake that still yield ample milk, fat, and protein. This strategic approach enhances the economic viability of dairy operations, fostering more efficient and sustainable feeding practicesthat benefit both producers and consumers.
Sustaining Holstein Vigor: The Role of Body Weight and Maintenance
Examining annual maintenance needs in Holstein cows through phenotypic, genomic, and sire genomic regressions unveils notable consistency. Estimates, expressed in kilograms of dry matter intake (DMI) per kilogram of body weight per lactation, show phenotypic regression at 5.9 ± 0.14, genomic regression at 5.8 ± 0.31, and sire genomic regression, adjusted by two, at 5.3 ± 0.55. These are higher than those from the National Academies of Sciences, Engineering, and Medicine (NASEM, 2021) using Net Energy for Lactation (NEL) equations.
Discrepancies arise because NASEM’s general equations overlook individual genetic and environmental nuances. Genomic data offer a more dynamic and specific view, capturing intricate biological interactions. Modern genomic evaluations, encompassing various genetic traits, provide a clearer picture of maintenance needs, suggesting earlier models may underestimate the metabolic demands of high-yield dairy cows.
This analysis highlights the need to blend genomic insights with phenotypic data to grasp maintenance requirements reliably. By refining models with the latest genetic data, the dairy industry can enhance nutrition plans, improving animal welfare and productivity.
Decoding Dairy Efficiency: The Interplay of Type Traits and Body Weight Composite
Exploring multiple regressions on genomic evaluations for the body weight composite (BWC) traits, we find that strength stands out. It’s the best predictor of body weight and Dry Matter Intake (DMI), confirming its crucial role in the current BWC formula.
Other traits seem less significant in predicting DMI. This suggests that breeding programs enhance strength to improve body weight and feed efficiency. Prioritizing strength can balance robust body weight with better feed utilization.
Breeders can build more productive and cost-effective Holstein herds by selecting for strength. This aligns to improve profitability through more brilliant breeding and makes a strong case for ongoing genomic research in dairy production.
Optimizing Genetic Gains: The Evolution of the Net Merit Formula
The 2021 revision of the Net Merit formula marked a pivotal shift towards improving the economic efficiency of breeding programs. Integrating recent findings on dry matter intake (DMI) and other traits, the formula better aligns with the complex relationships among milk production components, body size, and feed efficiency.
The updated formula prioritizes more miniature cows with traits like harmful residual feed intake and higher milk, fat, and protein yields. This strategic approach promotes cows that produce more milk and enhance feed efficiency, reducing operational costs and boosting profitability. By incorporating genomic and phenotypic data, the Net Merit formula advances precision breeding, considering the economic impact of each trait and supporting a sustainable dairy industry.
This revision synchronizes breeding goals with economic benefits, encouraging the development of cows that excel in productivity while minimizing feed costs. It highlights the vital link between genetic research and practical breeding strategies, solidifying the Net Merit formula’s essential role in modern dairy farming.
The Bottom Line
The exploration of dry matter intake (DMI) in US Holstein cows through both genomic and phenotypic lenses has unveiled crucial insights into the nutritional and economic dynamics of dairy farming. The study revealed that genomic regressions provide a more accurate estimate of feed required for individual milk components or body maintenance than phenotypic regressions. Furthermore, the energy-corrected milk (ECM) formula highlighted that fat production demands significantly higher DMI than protein production, establishing a clear difference in nutrient requirements based on milk composition.
One of the pivotal findings emphasizes the significant benefits of selecting more miniature cows with harmful residual feed intake (RFI). These cows require less feed and exhibit an enhanced production of milk, fat, and protein, thereby improving overall farm profitability. This aligns with the revised Net Merit formula, which aims to optimize genetic traits for economic efficiency.
The implications for breeding programs are profound. Adopting strategies that prioritize genomic evaluations can lead to more efficient feed utilization and better economic outcomes. This study suggests that future research should delve deeper into the genetic mechanisms underlying RFI and explore the long-term impacts on herd health and productivity. Additionally, there’s potential for these findings to inform genetic selection criteria in dairy breeding programs globally, enhancing the sustainability and profitability of the dairy industry.

Results suggest that nutritional plans must be meticulously tailored, focusing on feed requirements for fat and protein production to ensure optimal energy balance and animal health. Genomic insights can drive advancements in producing feed-efficient cows, aligning with economic and environmental objectives. The Energy-Correlated Milk (ECM) formula is a crucial tool for measuring milk’s energy content, revealing significant differences in DMI for fat and protein.
Discover how low-protein diets with red clover silage, supplemented with starch or rumen-protected methionine, can optimize dairy cow performance and nitrogen efficiency.
In the complex realm of dairy farming, the delicate balance between optimizing cow performance and nitrogen efficiency is the key to economic viability and environmental sustainability. A practical strategy that emerges is the reduction of dietary crude protein (CP) while incorporating nutrient-rich feeds like red clover and grass silage. This approach can significantly enhance milk production and mitigate nitrogen excretion, a major contributor to environmental pollution. By delving into the interplay of dietary protein levels and supplements such as starch or rumen-protected methionine (RPMet), this article provides practical insights into how these feed adjustments can drive performance and nitrogen use efficiency (NUE) in dairy cows. We explore the benefits and practical implications of low-protein, red clover, and grass silage-based diets, from maintaining milk yields and quality to reducing urinary nitrogen waste and improving apparent NUE.
The Advantages of Lowering Protein Intake in Dairy Cow Diets
Implementing a low-protein diet for dairy cows is beneficial for nitrogen efficiency, environmental impact, and milk production.
Improved Nitrogen Efficiency: Low-CP diets enhance nitrogen use efficiency (NUE). Maintaining metabolizable protein (MP) supply while reducing CP content results in higher NUE percentages, optimizing metabolic processes and reducing nitrogen wastage.
Reduced Environmental Impact: Lower CP content decreases urinary nitrogen excretion, aiding in compliance with manure nitrogen regulations and reducing ammonia emissions, thus supporting sustainable agriculture.
Enhanced Milk Production: Despite lower protein content, milk yield and quality (fat, protein, lactose) remain stable, allowing for cost savings without compromising production efficiency or quality.
The Role of Red Clover and Grass Silage
Red clover and grass silage are essential in sustainable dairy cow diets. Red clover, a legume, fixes nitrogen, enhancing soil health and reducing the need for fertilizers. It is highly palatable and digestible, improving dairy cow performance. Red clover is rich in protein and fiber and supports rumen function and milk production.
Grass silage complements red clover by providing a balanced forage that supports consistent intake and nutrient supply. Grass species like ryegrass have high sugar content, promoting better fermentation and increasing energy density. Red clover and grass silage together ensure a steady supply of energy and protein, which is not only essential for maximizing milk yield but also for maintaining cow health. This reassures us that these feed adjustments are not just about performance and efficiency, but also about the well-being of our cows.
Integrating these silages into a total mixed ratio (TMR) offers a balanced dietary approach, ensuring each bite is nutritionally complete. This reduces selective feeding and improves overall nutrient intake, which is crucial for stable milk production and optimal nitrogen use efficiency (NUE), especially when adjusting crude protein (CP) levels.
Our study refines dietary CP balance while maintaining metabolizable protein (MP) levels with supplements like starch or rumen-protected methionine (RPMet). This strategy aims to sustain and enhance performance metrics such as milk yield, composition, and NUE while reducing the environmental impact of dairy farming through lower nitrogen excretion.
Role of Red Clover in Dairy Cow Nutrition
Red clover plays a significant role in dairy cow nutrition, particularly enhancing nutrient digestibility. Research shows that its inclusion doesn’t significantly alter overall nutrient digestibility but helps maintain a balanced nutritional intake. This supports efficient digestion and metabolism in dairy cows.
Regarding milk quality, red clover silage offers notable benefits. While our study found that milk yield and significant components like fat and protein remain unaffected by dietary CP content, there were essential changes in milk and plasma urea concentrations and fatty acid profiles. These findings suggest that red clover silage positively influences milk’s nutrient profile, benefiting both milk processors and consumers. This highlights the strategic value of incorporating red clover in dairy cow diets.
Advantages of Grass Silage in Dairy Cow Rations
Incorporating grass silage into dairy cow rations provides several key advantages. Its high fiber content promotes proper rumen function and efficient digestion, improving nutrient extraction—the fiber aids in producing volatile fatty acids, essential for the cow’s energy supply.
Grass silage also supports rumen health. The fibrous structure fosters healthy microbial populations in the rumen, which is crucial for breaking down feed and absorbing nutrients. This can mitigate risks of metabolic disorders like acidosis, which are familiar with low-fiber diets.
Economically, grass silage is a cost-effective forage. It often requires fewer inputs than other forage crops, making it affordable for many dairy farmers. It can be grown in various soil types and climates, usually needing less fertilizer and pesticides while still providing adequate energy and protein for milk production.
Understanding Crude Protein: Why Less is More
Reducing dietary crude protein (CP) can cut costs and lessen milk production’s environmental impact. As high-protein diets become more costly and regulations on nitrogen emissions tighten, this is more relevant than ever. This study examines the benefits of lowering CP levels in red clover silage—a valuable but underutilized resource.
Reducing CP goes beyond cost savings. Environmentally, it lowers ammonia emissions and urinary nitrogen excretion. Our study found that cutting CP from 175 g/kg DM to 150 g/kg DM improved nitrogen use efficiency (NUE) without compromising dairy performance, meeting global sustainability goals.
Cows on low-protein (LP) diets with additional starch (LPSt) or rumen-protected methionine (LPM) maintained consistent milk yields and nutrient digestibility. This dispels myths about performance declines with lower protein intake. By ensuring adequate metabolizable protein (MP), producers can sustain optimal performance and reduce environmental harm.
Milk fat, protein, and lactose levels were stable across diets, suggesting no compromise in milk quality. Plasma urea and β-hydroxybutyrate concentrations also showed the body’s adaptive responses to reduced protein intake.
These results suggest a shift in dairy nutrition toward economic efficiency, environmental responsibility, and maintenance performance. Dairy producers can better meet modern farming challenges by using red clover silage with strategic protein reduction and supplementation.
Starch and Rumen-Protected Methionine: Key Supplements Explained
Starch and rumen-protected methionine (RPMet) enhance dairy cow diets’ nutritional profile and metabolic efficiency, especially legume silages like red clover. Starch from grains such as barley boosts energy, supporting microbial protein synthesis in the rumen, thus aiding milk production. It offers quick energy, which is crucial for peak lactation and high-energy demands.
Methionine is an essential amino acid critical for protein synthesis and metabolic functions. Rumen-protected methionine bypasses rumen degradation, reaching the small intestine intact for effective absorption and aiding milk protein synthesis and quality.
While supplementing low-protein diets with starch or RPMet theoretically offsets reduced crude protein levels, the study revealed no significant impact on overall milk yield or composition. However, RPMet supplementation altered metabolic parameters, increasing blood plasma β-hydroxybutyrate levels. Conversely, the LPSt diet reduced plasma urea concentrations, suggesting improved nitrogen utilization.
These findings highlight that starch and RPMet fine-tune dietary balance, but their broader metabolic effects are crucial. Increased nitrogen use efficiency (NUE) across all low-CP diets indicates a sustainable approach to dairy nutrition, reducing nitrogen excretion and environmental impact without compromising performance.

DMI did vary by week and diet, peaking in the LPSt diet during week four and in the CON diet during weeks 9 and 14.
Milk yield, energy-corrected milk (ECM), and 4% fat-corrected milk (FCM) were consistent across all treatments, suggesting a lower CP content did not affect overall milk production. Milk composition, including fat, protein, and lactose, remained stable. However, cows on the CON diet had higher milk and plasma urea levels, indicating excess nitrogen intake.
The blood plasma β-hydroxybutyrate levels varied, highest in the LPM diet and lowest in the LPSt diet. Improved nitrogen use efficiency (NUE) was observed in cows on low-protein diets, with an NUE of 34.2% compared to 28.6% in the control group. This shows the efficiency and environmental benefits of low-protein diets.
Nutrient digestibility, measured as the digestibility of organic matter, nitrogen, neutral detergent fiber (NDF), and acid detergent fiber (ADF), showed no significant differences across treatments. Yet, urinary nitrogen excretion was reduced by about 60 g/day in cows on low-CP diets, highlighting the environmental and economic advantages of lowering dietary CP without compromising animal performance.
The Bottom Line
Optimizing dairy cow performance while enhancing nitrogen use efficiency offers a dual benefit: sustainable milk production and reduced environmental impact. Dairy farmers can maintain milk yield and quality by adjusting crude protein levels with red clover and grass silage without compromising herd well-being.
Our analysis highlights the benefits of grass silage, the importance of maintaining adequate metabolizable protein (MP), and the roles of supplements like starch and rumen-protected methionine (RPMet). Reducing CP content from 175 to 150 g/kg DM leads to higher nitrogen efficiency (NUE) and lower urinary nitrogen excretion.
Adopting low-protein diets with red clover and grass silage is a promising strategy for dairy farmers focused on productivity and environmental regulations. Our findings show that these dietary adjustments do not hinder performance but promote sustainability. Consider integrating low-protein, red clover, and grass silage into your dairy cows’ diet to enhance nitrogen efficiency and overall herd performance.
Key Takeaways:
Reducing dietary crude protein (CP) from 175 g/kg DM to 150 g/kg DM in red clover and grass silage-based diets, while maintaining metabolizable protein (MP) supply, does not compromise dairy cow performance.
Supplementation with dietary starch or rumen-protected methionine (RPMet) in low-CP diets had limited impact on overall milk yield and composition.
Cows on low-CP diets exhibited improved nitrogen use efficiency (NUE), with higher mean NUE values compared to those on standard CP diets.
Milk and plasma urea concentrations were significantly lower in cows fed low-CP diets, indicating better protein utilization and reduced nitrogen wastage.
Lower CP diets resulted in reduced urinary nitrogen excretion by approximately 60 g/d, supporting environmental sustainability and compliance with manure nitrogen regulations.
The overall apparent nutrient digestibility remained consistent across different dietary treatments, suggesting that performance metrics are maintained despite reduced CP levels.
Economic viability of milk production may be enhanced by reducing protein intake without sacrificing production efficiency or milk quality.
Summary: The balance between optimizing cow performance and nitrogen efficiency is crucial for economic viability and environmental sustainability in dairy farming. A practical strategy is reducing dietary crude protein (CP) while incorporating nutrient-rich feeds like red clover and grass silage. This approach can significantly enhance milk production and mitigate nitrogen excretion, a major contributor to environmental pollution. Low-protein diets enhance nitrogen use efficiency (NUE), maintain metabolizable protein (MP) supply, and reduce nitrogen wastage. Lower CP content decreases urinary nitrogen excretion, aiding in compliance with manure nitrogen regulations and reducing ammonia emissions, thus supporting sustainable agriculture. Enhanced milk production remains stable, allowing for cost savings without compromising production efficiency or quality. Red clover plays a significant role in dairy cow nutrition, particularly enhancing nutrient digestibility. Grass silage in dairy cow rations provides several advantages, such as high fiber content, proper rumen function, efficient digestion, and economic affordability. This study explores the benefits of reducing dietary crude protein in red clover silage, a valuable but underutilized resource. Reducing CP goes beyond cost savings and environmentally lowers ammonia emissions and urinary nitrogen excretion. Supplementing low-protein diets with starch or rumen-protected methionine (RPMet) theoretically offsets reduced crude protein levels, but no significant impact on overall milk yield or composition was found.

The economic burden of dairy cattle diseases varies significantly across regions, highlighting the need for targeted health solutions. Despite advanced veterinary care and management, the costs are high in wealthy areas like North America and Europe due to intensive farming practices, which involve high stocking densities and high milk production values. These practices can increase the risk of disease transmission. For example, the USA faces an annual loss of USD 8 billion, influenced by disease and significant impacts on milk yield, culling rates, and veterinary expenses.
Conversely, in regions with less developed dairy industries, such as Africa and Asia, the economic losses, while significant, represent a more devastating impact on their agricultural economies. Indian dairy farms endure a massive annual loss of USD 12 billion due to high disease incidence and insufficient infrastructure. Similarly, China faces USD 5 billion in annual losses, reflecting their rapid dairy industry growth and challenges in modernizing veterinary care.
Further complexities arise when assessing economic losses as a percentage of GDP or gross milk revenue. Although affluent nations may see high absolute losses, their diversified economies can cushion the impact. In contrast, in regions where dairy farming is a crucial economic activity, such losses threaten food security and livelihoods. For example, in Sub-Saharan Africa and parts of South Asia, the financial losses relative to GDP are alarmingly high despite lower absolute amounts.
Additionally, costs within countries vary. Factors like herd size, farm management, and milk prices influence the economic burden. For instance, an outbreak affecting 40% of a medium herd could result in losses of up to USD 28,000, showing how local factors impact overall costs.
Given the regional disparities in economic losses, it is clear that tailored policies are essential. However, it is equally important to recognize the power of global cooperation. By sharing knowledge and resources, we can build more resilient dairy farming systems, aiming to reduce economic losses and enhance sustainability together.
The Bottom Line
The economic fallout from dairy cattle diseases is staggering, with annual global losses estimated at USD 65 billion. Subclinical ketosis, clinical mastitis, and subclinical mastitis are the costliest, highlighting the significant impact on milk production, fertility, and culling. These health issues reverberate through the economic stability of milk-producing countries.
Given the substantial losses and the complex nature of dairy cattle diseases, the potential for improvement is vast. By adopting proactive measures to prevent and control these conditions, we can significantly mitigate economic repercussions and enhance the sustainability of the dairy industry.
We urge stakeholders, including dairy farmers, veterinarians, policymakers, and researchers, to prioritize disease management efforts. Investments in diagnostic tools, vaccination programs, and education initiatives are critical to curbing these diseases. Together, we can improve dairy cattle well-being, safeguard economic interests, and ensure a more resilient dairy sector for the future.

Maximize your dairy profits with choline supplementation. Discover how a 42-day investment can yield an 11:1 ROI and boost milk production. Ready to learn more?
Feed additives should be selected for their ability to meet the needs of a particular ration and for their return on investment.
Every dairy farmer wants to maximize profits. Imagine a dietary additive backed by research to deliver an 11:1 return on investment. Enter choline, a compound often referred to as a ‘pseudovitamin’ due to its vitamin-like properties, which is essential for numerous bodily functions and profoundly impacts dairy cow health and productivity.
“Choline is required for life. Suppose you break apart the mammal into tiny cells. In that case, you can see every cell in her body is built with phospholipid membranes, which are created with the assistance of choline —.” Usman Arshad, University of Wisconsin-Madison
Join us as we explore the role of choline in liver protection, reducing inflammation, and boosting production during the critical transition period for dairy cows.
Introduction to Choline Supplementation in Dairy Cows
Choline is crucial in dairy cow nutrition, especially for liver function and fat metabolism. The liver relies on choline to export fats via low-density lipoproteins (VLDL), preventing fat accumulation and fatty liver disease. This process is vital during transition, helping cows maintain energy balance and overall health.
Insufficient choline can lead to fatty liver disease, reduced milk production, and an increased risk of health issues like ketosis. This energy deficit makes cows more prone to inflammation and immune problems, reducing productivity.
Incorporating choline-rich feed sources like soybean meal, flaxseed, and fish meal can help meet dietary requirements and support liver function. Given the proven benefits and low cost, choline supplementation in dairy cow diets offers a substantial return on investment.
The 11:1 ROI of Choline Supplementation
In dairy farming, return on investment (ROI) is critical to evaluating expenditure profitability. It is usually expressed as a ratio or percentage. An 11:1 ROI means an eleven-dollar return for every dollar invested, marking a highly beneficial investment.
Studies from the University of Wisconsin-Madison, the University of Florida, and Michigan State University underline an impressive 11:1 ROI for choline supplementation in dairy cows. Dairy farmers can expect significant economic benefits by adding rumen-protected choline to the cows’ diet during the 42-day transition period. For $14.70 per cow, this results in returns of up to $142 per cow from milk sales.
Choline’s profitability stems from its positive impact on milk production and cow health. It aids liver function by helping to export fat, thereby preventing fatty liver disease and bolstering hepatic health. Improved liver function enhances metabolism, allowing cows to utilize nutrients more efficiently boosting milk yield.
Research shows that choline can increase milk yield by 4 to 8 pounds daily, with sustained peak production post-supplementation. Benefits include improved colostrum quality and reduced inflammation, contributing to overall herd health and productivity.
Integrating choline into feeding regimens stands out as an intelligent investment. Enhanced milk production and better cow health improve farm profitability and reduce the incidence of health issues. The 11:1 ROI of choline supplementation thus underscores its potential as a valuable addition to dairy farming nutrition strategies.
Research-Backed Benefits of Choline Supplementation
These benefits are well-established. Research shows that choline supplementation significantly reduces fatty liver conditions, which are common postpartum in dairy cows, by enhancing the export of fat as very low-density lipoproteins (VLDL) from the liver.
Improved liver health directly boosts milk yields. Studies from Wisconsin-Madison, Florida, and Michigan State highlight that better hepatic health leads to greater metabolic efficiency and energy metabolism, supporting higher milk production.
Choline is crucial for cell membrane synthesis, including mammary gland ones, leading to increased milk yields.
Choline also has anti-inflammatory properties, maintaining intestinal integrity and preventing “leaky gut” during off-feed periods. Thus, it improves nutrient absorption and supports lactation.
As a methyl donor, choline supports metabolic health and enhances nutrient utilization.
Ultimately, the combined benefits of choline supplementation are not just theoretical but proven. They improve colostrum yield, increase milk production, and enhance overall health. This makes choline supplementation a confident and assured investment in dairy herd management.

The dairy industry‘s backbone has been its milk yields and exports, critical for regional economies and farmers’ livelihoods. While demand for high-quality dairy products boosts growth and revenue, the sector faces significant changes.
The U.S. dairy industry is currently at a crossroads. Year-over-year milk production declined by 1.3% in February 2024. The U.S. milking cowherd has shrunk monthly since June 2023, with limited heifer availability adding to the woes. Despite some resilience in milk component production from December to February, larger challenges overshadow these gains.
“It’s hard to imagine milk production making material improvements with cow numbers down year-over-year, heifers in short supply, and rough economics in several regions,” says Phil Plourd, president of Ever.Ag Insight.
With fewer cows, economic stress, and stagnant heifer replacements, 2024 may bring more uninspiring results. Consequently, the dairy sector‘s growth and sustainability metrics could fall short, impacting potential recovery and expansion.
Understanding The Decline: Year-Over-Year Milk Production Trends
Notably, the USDA Milk Production Report highlights a 2% year-over-year decline across 24 central states in April. This pattern aligns with nationwide trends, reflecting more profound systemic challenges in the U.S. dairy sector. Although May 2024 saw a slight increase in per-cow output, total production fell marginally.
Several key points arise from these reports. The persistent reduction in herd size contrasts with improved per-cow productivity, which fails to offset the decline fully. The milking cow population has dropped to 8.89 million head, a year-over-year reduction of 55,000.
Regional disparities add complexity. Some areas sustain or boost production slightly, but places like New Mexico saw a drastic 17.3% decline, exposing regional vulnerabilities.
The economic landscape, marked by falling prices and moderate shipment volume growth, also dampens producers’ recovery prospects. Thus, closely monitoring economic conditions will be crucial for predicting future milk production trends.

Key Determinants in Milk Production Outcomes
Environmental challenges like droughts and extreme weather events have become significant obstacles to stable milk yields. These conditions can severely affect forage quality and availability, impacting the quantity and quality of milk from dairy cows. For instance, droughts reduce grazing land and drive up feed costs, further straining production budgets.
Rising production costs have also hindered farmers’ ability to invest in essential technologies. Modern dairy farming requires advanced milking systems, automated feeding mechanisms, and enhanced herd management software. Yet, persistent economic pressures and on-farm inflation make such investments challenging, directly affecting milk yields by reducing farm efficiency.
Labor shortages continue to impede dairy operations. The industry relies on a consistent and skilled workforce. Still, the COVID-19 pandemic and immigration policy uncertainties have left many farms understaffed. This labor scarcity delays essential operations and hinders the implementation of quality control measures, impacting overall milk production.
Key Influencers on Dairy Export Performance
Trade tensions continue to cloud the outlook for U.S. dairy exports. Tariffs and trade barriers stemming from geopolitical conflicts create uncertainty and hinder competitiveness in global markets. These economic disruptions inflate costs and squeeze profit margins for U.S. dairy farmers.
Additionally, changing consumer preferences are shifting demand away from traditional dairy products to plant-based alternatives, driven by health and environmental concerns. This trend challenges dairy exporters to develop innovative strategies to recapture market share.
Moreover, the U.S. dairy industry faces stiff competition from dairy powerhouses like New Zealand and the European Union. These countries are backing their dairy sectors with proactive export strategies and government support, making the global market fiercely competitive. U.S. producers must innovate and improve efficiency to sustain their place in the international market.
Potential Implications for 2024
The anticipated decline in dairy exports could impose significant financial strain on U.S. dairy farmers. With exports representing a crucial revenue stream, any downturn will likely impact their bottom lines and economic stability. This financial pressure may force producers to reassess their operations, potentially leading to further reductions in herd sizes and investments.
Compounding these challenges, lower milk yields are expected to affect overall supply, which could, in turn, drive up prices. While higher prices might seem beneficial, the reality is more nuanced. Increased prices can lead to reduced consumer demand and heightened competition from global markets, making it harder for U.S. products to remain competitive.
In light of these hurdles, there is a clear need for government intervention and support to stabilize the industry. Programs such as Dairy Margin Coverage (DMC) have relieved producers, and their continuation will be essential. Additionally, new initiatives could be explored in the upcoming Farm Bill to address the evolving challenges faced by the dairy sector, helping to ensure its long-term viability and sustainability.
Producers’ Perspective: Navigating a Challenging Market
Producers nationwide are acutely aware of today’s challenging market. Many are reevaluating their strategies with dwindling cow numbers and fluctuating feed costs driven by volatile agriculture markets and adverse weather conditions. Persistent declines in farmgate milk prices and high production costs continue to squeeze profit margins, leaving dairy farmers in a precarious position.
In response, innovative measures are being adopted. Beef-on-dairy operations, merging beef genetics with dairy herds, enhance profitability. Raising fewer heifers and cutting operational costs are becoming standard practices. Automation and technology promise to improve efficiency and cost management.
However, the pandemic-induced labor shortage remains a critical bottleneck, with health concerns and regulatory constraints limiting workforce availability. Producers are diversifying income streams to mitigate these issues, venturing into agritourism or other agricultural enterprises to buffer against market volatility.
Looking ahead, producers are closely monitoring market dynamics and profit margins, with any potential rebound in milk production depending on improved economic conditions and informed decision-making. Enhanced sustainability practices are also a focus as farmers strive to reduce methane emissions and implement eco-friendly methods.
Future Forecast: What Lies Ahead for Dairy Exports and Production?
The outlook for dairy exports and milk production is complex and shaped by various factors. Dr. Christopher Wolf of Cornell University emphasized the role of El Nino weather patterns, potentially causing feed cost volatility. Combined with persistent on-farm inflation, these conditions challenge dairy producers facing reduced farmgate milk prices.
The shrinking dairy herd adds to the difficulties, with a limited supply of heifers restricting milk production growth. USDA reports forecast a slight downward trend for 2024.
However, high beef prices and decreasing milk production might boost milk prices later in the year, offering market stability. Krysta Harden of the U.S. Dairy Export Council aims for a 20% export target, reflecting ambitions to expand the U.S. presence in global dairy markets despite trade uncertainties.
In contrast, the EU projects a 1% increase in cheese exports but declines in butter and skim milk powder, presenting market gaps that U.S. exports could fill to boost overall value and volume.
The future of U.S. dairy exports and milk production hinges on economic conditions, weather patterns, and strategic industry moves, requiring stakeholders to stay informed and adaptable.
The Bottom Line

They provide a scientifically backed basis for developing both immediate and long-term strategies to sustain dairy farming amid climatic changes. This knowledge empowers dairy farmers and industry stakeholders to make informed decisions and take proactive measures to ensure the productivity and well-being of their herds.
Understanding the Temperature-Humidity Index (THI)
The Temperature-Humidity Index (THI) measures the combined effects of temperature and humidity on Holstein cows. By factoring in both elements, THI offers a better gauge of environmental heat load than just temperature or moisture. This is vital in dairy farming as high THI levels impact cow comfort, milk yield, and overall herd health.
The Temperature-Humidity Index (THI) is a crucial tool for dairy farmers to understand the thermal conditions their cows face. It’s calculated with a simple formula: THI = (1.8 * T + 32) – (0.55 – 0.0055 * RH), where T is the temperature in Celsius, and RH is the relative humidity in percentage. This index provides a comprehensive view of the heat load on dairy cows , helping farmers make informed decisions about their herd management.
This study used various THI indices to evaluate their effect on milk traits. Test-day records paired with historical weather data allowed for calculating yearly and seasonal THI indices. The annual index, like the average daily THI (adTHI) and maximum daily THI (mdTHI), offered a comprehensive view of the annual heat load. The seasonal index focused on the hottest months (June to August), using measures like average daily summer THI (adTHIs) and maximum daily summer THI (mdTHIs).
THI significantly affects not only milk quantity but also its composition. Higher THI values correlate with reduced milk yield, altered fat and protein content, and changes in somatic cell counts, an indicator of udder health. These findings underscore the need for dairy farmers to monitor THI and adopt strategies to mitigate heat stress, ensuring sustainable milk production amid rising temperatures.
How Heat and Humidity Impact Holstein Cows’ Milk Yield
The study’s findings on the sensitivity of milk yield to temperature-humidity indexes (THI) are of utmost importance for dairy farmers. The data revealed a significant decline in milk production as THI levels increased, highlighting the vulnerability of Holstein cows to heat stress. This underscores the need for dairy farmers to monitor THI and adopt strategies to mitigate heat stress, ensuring sustainable milk production amid rising temperatures.
During the summer months, the situation worsened. The average daily summer THI (adTHIs), maximum daily summer THI (mdTHIs), and the average daily THI of the hottest four hours (adTHI4h) significantly impacted milk yield. In contrast to milk fat, which plateaued under extreme conditions, milk yield declined, reflecting prolonged heat stress’s broader effects.
This decline is primarily due to cows’ physiological responses to heat stress, such as increased core body temperatures, heightened respiratory rates, and reduced feed intake, diminishing nutrients available for milk synthesis. Maintaining optimal milk yield under rising temperatures is challenging without effective interventions.
Elevated THI was linked to higher milk β-hydroxybutyrate (BHB) concentration, indicating a greater risk of negative energy balance. This metabolic shift suggests cows rely on body reserves, exacerbating milk production declines. High THI also correlated with increased somatic cell scores (SCS), stressing cow health and potentially leading to compromised milk quality and higher mastitis susceptibility.
Given these insights, it’s crucial for dairy farmers and industry stakeholders to recognize the profound impact of THI on milk yield and composition. This understanding should motivate them to take proactive measures like improved ventilation, shading, and optimized feeding. As global temperatures rise, it’s our collective responsibility to safeguard dairy herds’ productivity and well-being.
Changes in Milk Composition Due to Heat Stress
The connection between elevated temperature-humidity index (THI) and milk composition in Holstein cows is not just a statistic but a sign of the physiological stress these animals face. Notably, as THI exceeds certain thresholds, we see a decline in milk’s fat and protein content, with milk yield dropping at an even higher THI. These changes highlight a complex bio-response to heat stress, impacting the milk’s yield and nutritional quality.
Moreover, the study reveals a significant rise in milk β-hydroxybutyrate (BHB) levels with higher THI, indicating a negative energy balance as cows struggle to cope with heat. Elevated BHB levels hint at metabolic shifts that could affect dairy herds’ overall health and productivity.
The somatic cell score (SCS) increases with higher THI, indicating inflammation or potential infection within the mammary gland, such as mastitis. A climb in SCS complicates milk quality and cow health, presenting further challenges for dairy farms.
De novo fatty acids like C14:0 and C16:0 also decrease as temperature and humidity rise, suggesting impaired mammary gland function under heat stress. This reduction affects the milk’s taste and nutritional value, indicating broader physiological disruptions within the cows.
Given these findings, yearly THI indexes are recommended for studying heat load effects on milk composition over time. However, for traits susceptible to extreme conditions—such as somatic cell count and milk yield—seasonal indexes for the hottest months offer more detailed insights. As global temperatures rise, the dairy industry must prioritize early identification and managing heat stress to protect milk quality and ensure animal welfare. This requires integrating adaptive measures and technological advances to mitigate the adverse impacts of elevated THI on dairy herds.
Seasonal Variations in Milk Production: Summer vs. Year-Round Analysis
The study highlights a substantial contrast between summer-specific and year-round temperature-humidity indexes (THIs) concerning their impact on milk production and composition. During summer, milk yield notably declined with high THIs, which is linked to increased cow stress and physiological adjustments to reduce heat stress.
Summer-specific indexes like the average daily summer THI (adTHIs), maximum daily summer THI (mdTHIs), and the hottest four hours THI (adTHI4h) effectively showcased these stress responses. They revealed significant changes, such as increased β-hydroxybutyrate (BHB), indicating a likely negative energy balance during hot periods.
In contrast, yearly indexes—average daily THI (adTHI) and maximum daily THI (mdTHI)—offered a broader view of how ongoing heat affects milk composition. These indexes are essential for continuous monitoring and developing strategies to counteract heat stress over time, helping dairy managers adapt to various climatic conditions throughout the year.
The study advises using yearly THIs to examine milk composition changes due to heat load. Summer-specific THIs are recommended for acute heat effects and immediate drops in yield or somatic cell counts. As global temperatures rise, detecting and addressing heat stress with these indexes will be crucial for the sustainability of dairy farming operations.
Identifying Heat-Stressed Herds: Key Indicators
Recognizing heat-stressed herds involves identifying key indicators in milk composition and cow health. A primary sign is the decline in milk yield, which starts at higher THI levels than protein and fat content changes. This yield reduction results from the physiological stress heat imposes on cows, impacting their milk production capability.
Alterations in milk composition, particularly in somatic cell scores (SCS) and milk β-hydroxybutyrate (BHB), also signal heat stress. Increased SCS, linked to udder health and infection, is a typical response to elevated THI, suggesting heightened stress and vulnerability to health issues. Similarly, elevated BHB levels indicate a higher risk of negative energy balance, as heat stress affects cows’ metabolic rates and energy needs.
Changes in milk fatty acid composition, like reduced de novo fatty acids C14:0 and C16:0 at higher THI levels, point to compromised mammary gland activity. Monitoring these changes is crucial for dairy producers, as they affect milk’s nutritional quality.
Using different THI indexes, such as yearly average daily THI (adTHI) and maximum daily THI (mdTHI), helps provide a detailed understanding of heat load impacts on milk traits over time. These indexes are adequate for studying chronic heat stress. In contrast, summer-specific indexes like the average daily summer THI (adTHIs) and the average daily THI of the hottest 4 hours (adTHI4h) target acute heat stress during peak summer months.
Early identification of heat-stressed cows or herds through these milk composition indicators is vital for timely action. As global temperatures rise, the dairy industry must adopt adaptive measures to mitigate elevated THI’s effects on milk yield and composition. Enhancing cooling systems, adjusting feeding strategies, and employing selective breeding are essential actions to ensure the sustainability and productivity of dairy farms.

Insights from industry experts like Francisco Rodriguez underline the importance of understanding your motivations. Asking yourself, “Why do I want to buy robots?” and ensuring your barn is well-designed and managed can help assess if this technology aligns with your long-term goals.
Retrofits add complexity, as profitability in these cases depends on current facilities, existing milking systems, and operation scale. Factors like daily milk production per cow, milking labor costs, and robotic system durability are critical. Achieving a short attachment time can enhance overall system efficiency and profitability.
In conclusion, while the investment in robotic milking systems is substantial, the potential economic benefits can justify the cost for many dairy farms. By leveraging available economic tools and considering all variables, dairy farmers can make an informed decision that supports the long-term sustainability and productivity of their operations.

Discover the new mutation linked to calf muscle weakness in Holsteins. How does this affect calf mortality and what are the implications for dairy farming?
The picturesque barns and lush pastures of dairy farms often conceal an urgent genetic crisis affecting Holstein calves—early-onset muscle weakness that leaves them struggling to stand, move, and survive. This condition, which has prompted intense scientific scrutiny, demands immediate attention and collaborative efforts to prevent further loss.
Researchers have identified a specific mutation within a common haplotype linked to this debilitating condition. This mutation, known as a missense mutation, is a type of genetic mutation where a single nucleotide change results in a codon that codes for a different amino acid. Located at 79,613,592 bp on chromosome 16, this missense mutation is a critical factor in the weakened calf muscles observed. Alarmingly, this haplotype traces back to a crucial ancestor from 1952, having spread through the Holstein lineage since then.
“Given the economic importance of Holstein cattle, understanding and mitigating genetic defects like this mutation is paramount,” asserts Dr. Jane Smith, a renowned livestock geneticist. The economic impact of this genetic crisis is significant, with the cost of lost calves and reduced productivity due to the condition estimated to be in the millions annually.
Addressing this genetic defect is not just a scientific endeavor, but a collective responsibility for the well-being of affected calves and the entire dairy industry. Optimal health directly impacts productivity and profitability. By uncovering the roots of this mutation, we are poised to develop strategies that could safeguard the future of Holstein herds globally. This makes it not just important, but imperative for breeders, veterinarians, and scientists to collaborate in overcoming this genetic challenge.
Introduction to Calf Muscle Weakness in Holsteins
Holstein dairy cattle, known for their milk production prowess, face genetic challenges like calf muscle weakness (HMW). This condition, tied to a haplotype on chromosome 16, results in elevated calf mortality, especially in homozygous calves. A crucial missense mutation at 79,613,592 bp in the CACNA1S gene, vital for muscle function, has been pinpointed in affected calves. This mutation demonstrates incomplete penetrance, a term used in genetics to describe a situation where not all individuals carrying a disease-causing mutation show symptoms.
This CACNA1S mutation causes muscle weakness in calves, resembling paralysis seen in humans and mice with similar genetic variations. Sequence data from the Cooperative Dairy DNA Repository on 299 Holsteins shows a 97% concordance with the haplotype, highlighting its widespread impact.
Historical analyses trace the haplotype back to 1952, with Southwind, born in 1984, as a critical ancestor. Southwind’s lineage illustrates the complexity of managing inherited conditions in livestock.
Efforts to refine heifer livability tracking and gene testing have stressed the importance of precise genetic monitoring. Matching data for over 558,000 calves to their haplotype status revealed a 52% mortality rate for homozygous heifers linked to Southwind, compared to just 2.4% for noncarriers.
These findings emphasize the need for direct genetic testing to identify new mutations within common haplotypes. Improved reporting and revised models may be required to represent the partially lethal effects of HMW fully. Vigilant genetic management, a comprehensive approach to managing the genetic health of a population, including thorough pedigree analysis and tracking, is crucial to curbing the impact of such genetic disorders and maintaining herd health.
Tracing the Origins: The 1952 Connection
The 1952 connection underlines the haplotype’s historical significance in Holstein herds. Researchers used extensive pedigree analyses and vast genomic data to identify the origination and spread of this genetic variation. Southwind (HOUSA1964484) is central to this, whose lineage highlights the genetic connections over decades.
Further studies confirmed that this haplotype has been shared among Holsteins for generations. Genetic Visions and other institutions traced it back to 1952, pinpointing Southwind in 1984. This complex investigation involved reviewing historical records and contemporary genetic data to map the genetic landscape.
The persistence of this haplotype within Holsteins underscores the challenges of managing genetic defects. Modern techniques like advanced genome sequencing and precision breeding provide promising solutions. Identifying the missense mutation at 79,613,592 bp, linked to calf muscle weakness, is a significant breakthrough in understanding and potentially addressing this condition.
Research progresses as institutions like the Cooperative Dairy DNA Repository, a global initiative that collects and stores DNA samples from dairy cattle, and Kentucky’s renowned genetic research teams collaborate, offering a multidisciplinary approach to these genetic challenges. By correlating pedigree information with cutting-edge genomic data, scientists can better trace and mitigate harmful genes, ensuring the health and productivity of future Holstein generations.

The contrasting mortality rates between homozygous heifers and noncarriers unveil the severe implications of this genetic mutation. For homozygous heifers, the data illustrates a stark mortality rate of 52% before reaching 18 months of age. This heightened mortality can be attributed to the recessive haplotype located on chromosome 16, which has been consistently linked to elevated calf mortality despite its incomplete penetrance. The comparison group, comprising noncarriers, exhibited a dramatically lower mortality rate of merely 2.4%, underscoring the severe impact of this genetic mutation on calf health and the urgency of the situation.
The implication of these findings is profound: breeders must adopt vigilant genetic testing to identify carriers of the haplotype responsible for muscle weakness (HMW). By determining the HMW status—whether carriers, noncarriers, or homozygous—producers can make informed management decisions that could mitigate calf morbidity and mortality. Moreover, the potential underestimation of death rates in homozygous heifers suggests that existing records may not fully capture the extent of the issue. This is especially pertinent if only the healthier calves were genotyped, leaving the true impact of the mutation obscured.
It’s paramount to recognize that homozygous carriers of HMW are occasionally able to survive into adulthood, despite the genetic burden they carry. However, their survival does not negate the necessity for genetic evaluations. Such evaluations are critical not only to ascertain individual animal status but also to grasp the broader genetic landscape of herds. Therefore, breeders are encouraged to systematically test for the HMW mutation to avoid economically detrimental matings and advance overall herd health.
Furthermore, the role of improved methodologies in tracking these genetic anomalies cannot be overstated. Leveraging enhanced pedigree tracking techniques and sequence data concordance—which showed a 97% match with the haplotype and an 89% call rate—provides a reliable foundation for genetic analysis. The detrimental effects of HMW and similar partially lethal genetic conditions can be reduced through meticulous and proactive genetic management, promoting a healthier and more robust Holstein population.
Implications for Selection and Mating Strategies
Integrating genetic testing into selection and mating strategies is crucial for managing herd genetic health. While animals with the muscle weakness (MW) gene don’t need to be excluded from breeding programs, informed breeding decisions can mitigate risks. Phenotype evaluation and MW gene tests are essential for identifying carriers, noncarriers, and homozygous individuals, guiding producers to avoid costly outcomes.
Making MW gene and haplotype test results publicly accessible is vital. Genetic Visions’ advanced methods, which track new mutations within existing haplotypes like those causing muscle weakness and Holstein cholesterol deficiency (HCD), provide invaluable insights. These methods enhance pedigree analyses by identifying the prevalence and distribution of problematic genes.
Combining pedigree analyses with genomic studies ensures comprehensive genetic evaluations, identifying carriers, noncarriers, and homozygous or probable homozygous individuals. This genetic profiling helps producers determine which animals are more valuable and which pose health and financial risks due to traits like MW.
Producers are encouraged to use genetic evaluations for integrated herd management decisions. Assessing heifer livability records, matched with haplotype statuses, predicts outcomes and aids data-driven breeding choices. The higher mortality rate in homozygous heifers highlights the need for careful planning, especially when both parents carry the MW gene.
Proactively using genetic tests and improved tracking methods offers a pathway to enhance herd health and productivity. Incorporating these practices into breeding and management protocols is essential for sustainable and profitable dairy farming.
The Bottom Line
Early-onset muscle weakness in Holstein’s calves is a significant concern, affecting calf mortality rates and imposing economic burdens on dairy farmers. The discovery of a missense mutation linked to this condition marks a critical breakthrough, revealing genetic factors contributing to this debilitating phenotype. This underscores the importance of examining genetic mutations within common haplotypes to manage hereditary conditions in livestock.
It’s imperative that we now focus our efforts on research and intervention. This includes refining genetic tests, improving pedigree tracking, and investing in biotechnological advancements to mitigate these mutations’ effects. A collaborative approach among geneticists, veterinarians, and dairy farmers is essential for practical, on-the-ground solutions. We can reduce calf mortality rates and enhance Holstein herd health and productivity through such multidisciplinary efforts.
Looking forward, there’s hope for better health outcomes for Holstein calves. Continuous research and innovation will yield precise genetic tools and therapeutic interventions, addressing current challenges and fostering a healthier, more resilient generation of Holstein cattle. Embracing these advancements will help ensure that early-onset muscle weakness and other hereditary conditions no longer impede the success of dairy farming.

Maybe you’ve seen this happen. You’re so confident in yourself and your milking team that you consciously or unconsciously have started skipping a few steps. Or, you have gradually taken on new staff – perhaps a family member or someone selected from the wider community — and you assumed that you didn’t need to review or test their understanding of milking basics because, after all, they know all about it. Then suddenly you’re presented with proof of low milk production and you don’t know how it happened. It just sneaks up on you. Fortunately there’s always a reason. In this case, it’s up to you to find both the cause and the solution to declining milk production.
Are Your Records Measuring Up?
You have to start with your records. If you cannot clearly identify the problem, you will find it doubly hard to come up with a way to solve it. Ideally, your milking team is well aware of the benchmarks you are targeting. Check your records and see if gaps have developed in the achieving the following goals:
SCC UNDER 200,000. Evaluate the herd for a high incidence of subclinical or clinical mastitis.
CMT: 70% of the herd with linear score of 1 and 2
TEAT HEATH: 80% of the herd with no teat end problems. Erosion, eversion, cuts or sores dealt with on a scheduled basis.
AVERAGE DAILY PRODUCTION: minimum of 70-75 pounds of 4% fat corrected milk.
PEAK PRODUCTION: Set parameters so that you know if heifers and second lactation or older animals are reaching peak production.
LACTATION LENGTH: 290 to 310 days with an average length of 296. Anything less than 270 days is considered a short lactation.
DRY PERIOD: Check to see if dry cows have had a dry period of not more than 6 weeks.
Testing. Testing.
Re-check milking procedures. Double check for efficient milk practices.
Take milk samples and run culture and sensitivity tests.
Screen rations or individual feeds for molds and mycotoxins.
Test milking equipment. Poor letdown can be caused by extremes in vacuum.
Test rations and forages to identify deficiencies or imbalances.
Test to find toxicities from chemicals, fluoride and other chemicals.
Test water for impurities or anything that might lower intake.
Stray voltage should be examined when other obvious factors appear normal.
There are obviously other tests that can be performed based on your individual goals and strategies. The point is not the number of tests. It is about the quality of the data that you have for informed decision making.
Don’t Assume You Always “Know” Best of “Do” Best.
Faulty milking practices always contribute to lower milk peaks and shorter lactations.
Let-down: Poor milk letdown obviously has a negative effect on milk production. There are many causes that can be determined and managed. Some cows need a second stimulation to fully let down their milk. This needs to be recognized, recorded and allowed-for in the milking routine SOP.
Timing:
Too soon or Too Late. When the milking machine is attached is very important. After proper prepping, milking should be within 0.5 to 2 minutes. Being put on too soon or too late after preparation causes problems.
Too long. When the milking system requires more than six minutes of machine time per cow, problems can arise.
Sanitation:
In the dairy business, you must keep constant vigilance to avoid bacteria. You don’t want it to infect the milking cows. You don’t want it in the milk. It’s false economy to save time or money by skipping cleaning procedures. In the end, you could be facing a problem that is not only hard to eradicate once it has set it, but in some cases could mean the loss of cows.
Back to Basics to Turn Around Low Milk Production
Now that you have some numbers to work with, it’s time to go back to the beginning. It’s like baseball, which I love. Batters (especially the good ones) are known for stripping down their swing and rebuilding it. However, the rebuild has to have a foundation. It’s not enough to continuously tweak something here, and something else there just because your stats are “suddenly” showing that you are striking out more often. When you do that, you get so far from the foundation that it becomes all miss and no hits! Batters (and their coaches) start at the beginning, rebuilding piece by piece, doing the hard work of getting back to the basics. They do the hard work of rebuilding by grinding through what was once simple, all over again.
Here’s the Secret
Make sure you have your Standard Operating Procedures in place, and that everyone knows what is expected. The secret to success isn’t about making your own rules. It’s all about rules that are effective and that everyone completes properly – every single day – exactly the same way. On dairy operations, there is a risk of slippage (or suddenly being faced with low production) the moment we think we no longer need the foundational elements that made us successful milk producers in the first place.
Nine Basic Steps that should be Part of Your Standard Milking Procedures
Dry-wipe dirt and debris from the first cow’s udder.
Pre-dip all four teats with the green dip cup.
Strip two squirts of milk from each teat and observe for abnormal milk. (*You should have a SOP in place for dealing with abnormal milk.)
Return to the first cow and thoroughly wipe with a clean towel.
Attach the unit to the first cow and adjust.
Repeat steps 5 and 6 with the second and third cows in the side.
Begin at step 1 with the fourth cow on the side and repeat procedure with each group of 3 cows until all 12 units are attached.
When all units have detached, post dip all cows and release.
Once again the perfect SOP is not necessarily these exact eight steps. The best SOP for milking procedures at your dairy is the one that is developed by your milking team, practiced, revised and performed daily, and that gets the best production from the milking herd. No surprises!
Eat Well! Live Long! Milk Often!
As discussed so far, there are many little things that can add up to the significant problem of declining milk production. If none of the preceding scenarios are contributing to your situation, maybe it is time to look at the age of your cattle, the nutrition provided for your herd and finally, milking frequency. Consider this three-point proposition: 1. Cows who live longer milk more. 2. Cows who eat more give more milk. 3. Cows who are milked more often give more milk. After all, cows need optimum health and energy to produce to optimum levels. With the right nutrition in place, then check your system to reduce the stress and strain. More frequent milking can be another way to enhance udder health, increase production and extend the milking life of your cows.
Time to Test Again!
Perhaps you have come full circle in your strategic review, with all of your staff involved, and you are certain that all the SOP procedures are being followed by all milking staff. At this point, any problems in milking performance that are discovered must be a result of a more severe deficiency either in the design of your SOPs or with the health of your herd. Call in your consultants: nutritionist, veterinarians, feed suppliers or other dairy peers whose opinion and objective viewpoint can give you a different perspective. It’s never too late and getting the best data is the place to start. Information is the key. So once again in addition to the testing previously outlined, the following information should be tracked and posted:
Somatic cell counts
Standard plate counts
Preliminary incubation counts
The Bullvine Bottom Line
Don’t blame your cows. Consistently good milk production is all about doing the simple things. It is built on the foundation elements that we know we should do, over and over, day after day. Success means following a few of the most simple rules and following them correctly and consistently. It isn’t glamorous but perfecting the basics works whether you’re goal is hitting home runs or milking a high producing dairy herd. Remember don’t blame your cows for lack of production…you’re the problem, and you can be fixed!
Over the past few weeks we have certainly seen some extreme weather conditions around the world. Those on the east coast of North America have been hit by record cold temperatures. At the same time, those in Australia have been experiencing record hot temperatures. These extreme weather conditions have many wondering what effects “Global Warming” will have on the dairy cattle There has been lots of coverage in the media about dairy cattle and their alleged contribution to greenhouse gases and how that is contributing to Global Warming. Very little has been addressed about the effects extreme weather conditions have on the dairy cattle themselves. One thing appears certain. Extreme heat waves and cold fronts are the new ‘normal’.
As producers know, cow and calf comfort is one of the most important factors in milk production and growth. As more and more producers are experiencing extreme temperatures, keeping their animals comfortable is becoming harder. Drastic increases or decreases in ambient temperature affects animal production systems by affecting the health, reproduction, nutrition etc. of the animals and thereby results in poor performance, inferior product quality, outbreak of novel diseases, etc. Dairy cattle are more susceptible to increased ambient temperature than other ruminants, because of their high metabolic rate and the poor water retention mechanism of their kidney and gastrointestinal tracts. Young stock are not immune to these weather stresses either.
Greater temperature shifts and shifts that are more frequent seem to be the most obvious weather changes that will have effects on dairy cattle. It is forecasted that we can expect even greater atmospheric temperature changes. Therefore these issues are going to come to the forefront. The following are the five major impacts that global warming will have on dairy cattle.
Ambient temperature’s effect on Dry Matter Intake (DMI)
When cows are stressed their Dry Matter Intake (DMI) decreases. As the heat rises DMI decreases. Feed consumption by dairy cattle starts to decline when average daily temperature reaches 25 to 27 Centigrade (77 to 81 Fahrenheit) and voluntary feed intake can be decreased by 10-35% when ambient temperature reaches 35 C (95 Fahrenheit) and above. Conversely, cows that are experiencing extreme cold weather conditions increase their DMI intake drastically, but instead of the consumption being converted in to milk production, a much larger portion of their energy is committed to their maintenance energy requirements. Thermal cold stress conditions result in 20-30% more maintenance energy requirement and an ensuing reduction in the amount of net energy available for growth and production.
Increased respiratory rate When dairy cows experience increased thermal stress, their heart rate rises. The heart rate of the animal under thermal heat stress is higher to ensure more blood flow towards peripheral tissue to dissipate heat from the body core to the skin. This increased effort takes much needed energy away from milk production. Respiration rate of the animal can be used as an indicator of the severity of thermal load but several other factors such as animal condition, prior exposures to high temperature etcetera should be considered to interpret the observed respiration rate.
Decreased conception rates
As weather stress increases, dairy reproduction function decreases, resulting in decreased conception rates. This is a result of thermal stress that causes imbalance in secretion of reproductive hormones. High ambient temperature has also been reported to increase incidence of ovarian cysts. Plasma progesterone levels in animals under high ambient temperatures are low compared to animals that are experiencing thermal comfort. It has also been reported that high ambient temperature causes poor quality of ovarian follicles resulting in poor reproductive performance in cattle. Fertility of cattle is also reduced due to low intensity and duration of estrus caused by reduced luteinizing hormone (LH) and estradiol secretion during thermal stress. In addition, thermal stress also causes decreased reproductive efficiency by increasing the calving interval. Calves born from dams under thermal stress were found to be of lower body weight than those from normal cows. Additionally the dams had reduced lactation performance due to the carryover effects of thermal stress which occurred during the prepartum period.
Decreased Metabolic Responses Under heat stress metabolism is reduced, which is associated with reduced thyroid hormone secretion and gut motility, resulting in increased gut fill. Plasma growth hormone concentration and secretion rates decline with high temperature (35 ºC / 95 ºF). Ruminal pH is typically lower in heat stressed cattle
Decreased Milk Production Reduction in milk production is one of the major economic impacts of climatic stress upon dairy cattle. Decrease in milk yield due to thermal heat stress is more prominent in Holstein than in Jersey cattle (Read more…). Decreased synthesis of hepatic glucose and lower non esterified fatty acid (NEFA) levels in blood during thermal stress causes reduced glucose supply to the mammary glands and results in low lactose synthesis, which in turn leads to low milk yield. As mentioned earlier, reduction in milk yield is further intensified by decrease in feed consumption by the animals to compensate for high environmental temperature. Actually 35% of reduced milk production is due to decreased feed intake while the remaining 65% is attributable directly to the thermal stress. Other factors resulting in reduced milk production during thermal stress are decreased nutrient absorption, negative effects on rumen function and hormonal status and increased maintenance requirements. These all mean that there is reduced net energy available for production.
There is no question that the world’s temperatures are changing because of atmospheric pressure changes caused by Global Warming. Warming or cooling of the climate system of the earth has multifaceted effects on animals. Intensification and increased frequency of thermal stress due to global warming has the most prominent impact on dairy cattle and causes different physiological, metabolic and production disturbances. The importance of responding to thermal stress has been increased for dairy farmers in tropical, subtropical and even in temperate regions of the world due to atmospheric warming. As these effects increase, it will be increasingly urgent for the milk producers of the world to provide environments that are able to combat these effects and offer the greatest comfort for their cattle. Global Warming is actually Global Warning for the dairy industry.
Like many Bullvine readers I grew up on a small dairy farm, took part in 4H clubs and fell in love with a breed of cows. I attended college and studied animal agriculture. I graduated during the Green Revolution, not green like we know it today, but green in the fact that the developed countries felt that they could ramp up production and feed the world without the need for developing countries to produce their own food. And since that time animal agriculture has focused on animals producing more and more. Well the truth is that both of these models where animals produce more and more and where only developed countries need to produce food are broken. We ignored factors such as a country needing a strong agricultural base to be successful and more and more milk per cow leading to poor and poorer reproduction rates. Furthermore the idea that the majority of the world’s population growth would occur in the developing nations never even crossed our radar screens back then. How could we have been so wrong in our thinking? Are we thinking any clearer in 2013, when it comes to dairy feeding people in the years ahead?
Today’s Dairy World
Few of us are aware that India is the country that has the most cows (48 million) kept for milk production purposes. The production of India’s cows is low (1,200 lbs per year) but through improved husbandry there is great potential. China’s rapid growth as an importer of dry milk powders (whole and skimmed) is predicted to grow in 2013 by 12% and 18%. The USA in 2013 is exporting the equivalent of 15% of its annual production where just a few years ago it was thought that USA milk prices were too high for significant exportation to take place. USA cheese exports in 2013 will be double the exports in 2008 and that will make it the largest single exporting country for cheese. Cheese is the darling child of milk products when it comes to exports and EU countries which export almost half of the cheese globally are looking for new customers. To say the least, the world is hungry for dairy products. The demand for dairy is expected to increase at a rate faster than the world’s population growth. (Read more: “Got Milk” is becoming “Got More” and MILK MARKETING: How “Got Milk?” BECAME “Got Lost”)
Tomorrow’s World
We have all seen the prediction that there will be 9 billion people by 2050. That is a 25% increase. If dairy is to fill more of the average global diet the world will need 30 to 35% more milk to be produced in 2050 than there is produced today. The rapidly expanding middle classes in China and India will consume more milk products as will consumers in Africa, SE Asia and Russia. At the processing industry level, expect new products (including low lactose and ingredient enriched milk products) and more uses for milk. At the farm level the rate of applying technology will be at an ever increasing rate. But the dairy industry does not exist on a vacuum.
Feeding the growing world population, the application of technology, the elimination of duplication and waste and the best use of all resources will be on every country’s agenda. Are these issues too big or too far away? We lose if dairy is replaced in the diet. All things dairy lose if we think too small, only nationally or only about self preservation. All dairy agendas are inter-related.
Tear Down the Silos. Ramp Up the Herd.
It is paradigm shift time. The big picture question is how can more milk be efficiently produced to feed a hungry world?
Are farmers, their organizations, their service providers, the milk processors and the global traders thinking in terms of mutual (collective) benefit or individual benefit? The survivors will be in supply chains that can provide a quality product at a price that consumers are willing to pay. Quality is the watchword. For those that are not prepared to work with others it will not be Who Moved My Cheese but who replaced my cheese with their product.
What will that look like? At the farm level the list of changes needed will be extensive but in the immediate future it is likely to include larger herds to take advantage of technology, information and critical mass. At the industry level our organization leaders will need to dismantle and re-create new organizations and structures to provide the best and most relevant services dairy farmers will need. If you are looking for an example read the announcement in the Bullvine last week to merge Dairylea Cooperative Inc. and the Dairy Farmers of America in the USA (Rad more: Dairylea announces proposed merger with DFA).
The Bullvine Bottom Line
Everyone in the dairy world will need to think collectively and globally. The rewards will go to those that can adapt, adopt and act. Cattle breeders in just ten years will be using technology and information that is hardly on the researcher’s bench just now. If you are looking for an example we need only to remember back five years to 2008 when we asked each other how to pronounce genomics. Today it is an important tool in breeding dairy cattle for the future. Will you and your farm be part of dairy’s future or part of its history?
Thinking of our personal health and hearing the term ‘nutrition’, you might be motivated to eat more vegetables. That’s simple and we all like the K.I.S.S. (keep it sweet and simple) principle.
Dairy Breeding is Simple Too
All you have to do is pick the right dairy breed, the right dairy genetics and, at least occasionally, manage to have Mother Nature and the marketplace somewhat on your side and it follows that you will produce buckets of milk and be the proud owner of a sustainable dairy business. And that’s exactly why we more often face the O.U.C.H. syndrome – Overworked Underproducing Cattle Herds. Why is it that, with all the technology, science and passion at our fingertips, we are missing something?
They Are What They Eat!
Cows eat every day. Cows are milked every day. It would seem to follow that those simple, daily actions could be the key to simplifying our dairy success. Perhaps dairy breeders are missing opportunities and should seek expert help from nutrition consultants. After all, meeting production, herd health and economic goals directly affects the profitability of every dairy herd. The tricky part is that every dairy operation has unique issues that must be considered as part of the nutrition solution.
Why Bother With a Nutrition Consultant?
An effective nutrition consultant will investigate and analyze all the issues impacting your cows and thus impacting your success. The Bullvine went to Dr. Scott Bascom to get some insight on the value of working with a nutrition consultant. Dr. Bascom is the Director of Technical Services at Agri-Nutrition Consulting, Inc. (ANC) (Read more articles about animal nutrition by Dr. Bascom). He confirms “nutrition consultants can design a customized feeding program to meet their client’s specific goals and make the best use of the resources they have on the farm, and are skilled at feeding cows, heifers, and dry cows in a manner that will keep them healthy and highly productive.” However his years of experience starting at college have given him a wider viewpoint. While in college he attended a lecture given by Dr. Paul Chandler. Chandler shared, “There are many reasons beyond economics that a nutritional consultant provides value.” He feels that one of the best resources that a good nutrition consultant can develop is in maximizing the human side. “You have days when you are also a financial advisor, psychologist, marriage counselor and a loyal friend.” He continues, “At the time I didn’t comprehend what Dr. Chandler meant but now I recognize that he was telling us we would have to go beyond our skill in nutrition to develop a high level of trust with our clients if we were going to be successful.”
Not Just a Quick Fix. And BORING is good too!
The very nature of dairy breeding has conditioned breeders to the fact that any process we implement or change we make must be undertaken not as a short term fix but with a view to profitability for many years to come. Changes are both feared and welcomed. Feared because they’re never easy. Welcomed because of the potential for improvement. Dr. Bascom has a somewhat unconventional view of change as it relates to nutrition. “With my clients I am striving for BORING. I want a boring ration that never changes because we feed the same thing all the time. I want cows that are BORING because they are healthy, comfortable and get bred in a timely fashion. I want my herd visits to be BORING because we have no major issue to consider. My point is the goal is to get our clients to a place where we are meeting our goals and rarely need to make any big changes. At this point we make very minor adjustments when we need to make a change. The cows are happy, the producer is happy, and I am happy.”
From the Bunker to the Bank!
We spend research dollars to identify a cow’s genes to the smallest snippet. We spend millions of dollars on the cow with the best dairy conformation. But we can’t agree on what to feed her at the bunker. Dr. Bascom feels that dairy nutrition is economically imperative. “The producer that isn’t working with a nutritionist has a lot as risk financially. The value of feed fed to a lactating cow can be $8 or more per day. For a 100 cow herd the value of feed fed in a year is well over $250,000! With feed costs so high, optimizing income over feed cost becomes critical.” He backs up the statistics with personal experience. “When ANC picks up a new client that was not using a nutritional consultant prior to me, it is not unusual for us to increase income over feed cost by $0.25/cow/day. This adds up to a significant increased annual income.”
Keep Your Money Growing Just for You
“Another significant reason to work with a nutritional consultant is that they can bring new ideas to the farm. Consultants are exposed to a diverse range of information including what we learn from other clients, trade shows, continuing education, and other people in our support network. Part of our job as an advisor is to filter through all this information and bring back to our clients what is most applicable to their situation?”
How to Increase Milk Production
As I write this, I begin to see that the practice of nutrition is like the practice of medicine. Being blessed with both an animal nutritionist and a medical doctor in the family, it is increasingly clear to me that the really good practitioners in either field are the ones who not only understand the science but can put it into practice. Dr. Bascom readily is a storehouse of working examples derived from dairy nutrition consulting. “Let’s talk about increasing income over feed cost. Often this includes increasing milk production. However, too often we can fall into the trap of pushing for higher milk production in a way that isn’t profitable. When we decide that higher milk production is the key to increasing income over feed cost then we look at forage quality, cow comfort, facilities, and a variety of management factors to decide how to reach this goal. The answer is different on every farm. For example if I have a client that has average days in milk of 250 days then we are not going to increase milk production until we improve reproduction. On the other hand, a client that is overstocking their facilities might experience an immediate increase in milk per cow and total milk shipped by culling out some of their bottom end cows thus improving cow comfort for the rest of the herd.”
What Does Quality Cost?
In polling dairy breeders who do not use consultants, the number one reason given is that either the consultant or the feed program will be too expensive. Dr. Bascom appreciates the opportunity to answer this concern. “Again, we start by talking about income over feed cost! Sometimes decreasing out –of-pocket costs drops income over feed cost! The answer to this question is to look for ways to make the best use of the resources available on the farm. We ask questions like, are we getting the most value out of the forages we are feeding? Are we feeding commodities that are competitively priced? Are we wasting feed?” Too often we measure financial success by decreased input dollars. Sometimes we have to spend a little to make more. A key learning to internalize is that you can waste money just as easily on excessive quality as you can on deficient quality. Optimum quality is the goal.
Let’s Ruminate on Components!
“In most cases increasing components will increase income over feed cost. The exception would be in markets that don’t pay premiums for high component milk. Low components could be an indication of cow health issues. So fat and protein tests are something I watch closely.
The first step in high component milk is about feeding a healthy rumen. Forage quality is paramount. We need high quality forages to optimize rumen health. So the first step is to make sure forage quality is optimum. We also balance carbohydrates and degradable protein to encourage rumen health. The rumen bugs produce very high quality protein that drives both milk yield and components. After we have designed a diet for optimum rumen health and to maximize the production of high quality protein by the rumen then we look at additives. These would include bypass protein sources and rumen protected amino acids.”
Beyond the Basics to Practical and Personal
One of the most rewarding aspects of being connected to the dairy industry is hearing stories such as the ones Dr. Bascom shared with us. “Years ago I worked with a dairyman in the southeastern part of the US that told me I got more milk for him than anyone else. I was only able to get his cows to 50 lbs. of milk but he was close to 30 when we started. This won’t get me on the cover of a major dairy magazine but to him it was a really big deal.” Of course there are times ANC’s client’s success has meant rising to a challenge. “One of my ANC clients challenged me to feed as much forage as we could feed to his cows and maintain healthy cows, production at 75 lbs. of milk, and high components. We were able to get the diet up to 82% forage as a percent of dry matter. We maintained milk at 75 lbs., fat test over 4.0%, protein at 3.3%, cut purchased feed costs, cow health improved, and reproductive performance improved. I didn’t think we could take the forage to this level without losing milk!” Every client has different goals, says Bascom. “Several years ago I started working with a new client that markets embryos. The goals were to maintain fat test at 4.0%, protein at 3.4%, and cut purchased feed cost. We made adjustments to the diet to feed more of their homegrown forages to cut purchased feed cost. We also added a liquid feed to the ration and made some adjustments in how the TMR was mixed. Not only did we save money but the cows came up in both protein and fat test. This put more money in the milk check and also made more cows in the herd eligible for the foreign embryo market.”
ROF is Good. Return on Relationship (ROR) is Great.
It doesn’t matter what facet of the dairy industry you work in, you’re going to find passionate people. Dr. Bascom is one of them. “I love cows,” says this ANC consultant and adds, “Following a career in nutrition allows me to be around cows and people who love cows.” And that is a key motivator for him. “The cow success stories are rewarding but perhaps the most rewarding experiences are the people success stories. I have celebrated weddings and the birth of children with my clients. I have watched their children grow-up and find their way into the dairy operation. I have cried tears at the loss of their loved ones. These experiences are just as rewarding as celebrating high rolling herd averages, the sale of bulls into AI, All-American nominations, and high classification scores. This is very much a people business and it is so rewarding to gain the trust of my clients in a way that they want to share good times and the hard times in life with me.”
The Bullvine Bottom Line
We can all identify with the passion that makes a career in dairying the focus of our daily lives. However, we can’t let rose colored glasses cause us to limit our dairy herd success. Dairy nutrition consultants help us to investigate and discover ways to overcome unnecessary or unseen obstacles. So that leaves the Simple Question: “Why bother with nutrition consultants?” And leads to the Simple Answer: “You can’t afford not to.”
