Understanding Ketones and Ketosis: Boosting Dairy Cow Health and Productivity

Wednesday, June 19th, 2024

Discover how understanding ketones and ketosis can boost your dairy cow’s health and productivity. Are ketones the key to overcoming metabolic challenges?

For dairy farmers, the importance of herd health and productivity is undeniable. Beyond the daily tasks, ketosis’s metabolic process plays a significant role in determining the cows’ well-being and the farm’s profitability. Understanding ketones and ketosis is not just theoretical knowledge; it directly influences milk production, animal health, and financial stability. Neglecting ketosis can result in lower milk yields, increased disease susceptibility, and economic loss. By grasping the practical implications of this metabolic process, you can make informed decisions to improve your herd’s health and your farm’s success.

Ketosis, a crucial metabolic disorder, indicates a cow’s struggle with energy deficits, particularly during the high-stress transition into lactation. This can lead to early herd removal and significant economic challenges. We’ll delve into the reasons behind these metabolic changes and their impact on your herd, providing practical management strategies. We aim to simplify this science and offer insights you can immediately apply to enhance your herd’s health and your farm’s success. Explore the evolving understanding of ketones and ketosis in dairy cows.

The Vital Role of Ketones in Dairy Cow Lactation

Ketones are vital organic compounds that provide an alternate energy source when glucose is scarce. As dairy cows transition into lactation, their energy needs surge to support milk production. If their carbohydrate intake falls short, their bodies begin breaking down fat stores, producing ketones as standby fuel to sustain essential functions and maintain milk output.

This metabolic process is critical during the stressful transition into lactation. When a cow’s diet doesn’t supply enough energy, the liver converts fatty acids into ketones like β-hydroxybutyrate (BHB), acetoacetate, and acetone. These ketones circulate in the bloodstream, providing energy to the body’s tissues. While this is a natural adaptive response, over-reliance on ketones can lead to ketosis, a potentially harmful condition if not properly managed. Understanding this balance is crucial for keeping dairy cows healthy and productive.

Balancing Act: Healthy Hyperketonemia vs. Pathological Ketosis in Dairy Cows

Ketosis is a common metabolic issue in dairy cows, marked by elevated levels of ketone bodies in the blood. This usually happens when cows transition into lactation and face an energy deficit. When their energy needs for milk production exceed their nutritional intake, their bodies start mobilizing fat stores, producing ketones as an alternative energy source.

It’s important to differentiate between healthy hyperketonemia and pathological ketosis. Healthy hyperketonemia occurs when increased ketone levels help maintain energy balance without causing health issues. Conversely, pathological ketosis involves excessively high ketone levels that the cow’s metabolism can’t handle, causing toxic effects and health problems.

Pathological ketosis often appears in early lactation and can cause reduced milk yield, poor reproductive performance, and a higher risk of other metabolic disorders. The unpredictable nature of these outcomes is made worse by different factors like cow management, nutrition, and genetics, complicating the direct effects of ketosis.

Grasping the delicate balance between beneficial and harmful ketone levels is a game-changer for dairy farmers. By recognizing the intricacies of ketosis, you can develop better management strategies, enhancing the health and productivity of your dairy cows. This understanding holds the promise of a more successful and sustainable future for your farm.

Ketosis and Milk Production: Unraveling the Economic and Biological Complexities

Metric	Healthy Cows	Cows with Ketosis	Economic Impact ($ per cow)
Average Daily Milk Yield (liters)	30	25	-150
Incidence of Periparturient Disease (%)	5	20	-300
Culling Rate (%)	10	25	-500
Treatment Costs ($)	50	200	-150
Total Economic Loss ($)	N/A	N/A	-1100

The interplay between ketosis and milk production is crucial for dairy farmers. Typically, ketosis has been blamed for reduced milk yield due to energy deficits in early lactation. Subclinical ketosis can result in milk losses of 3-5 pounds per cow daily, translating to $0.54 to $0.90 per cow at $0.18 per pound, leading to substantial financial strain over time.

However, emerging research brings a fresher perspective. Some studies indicate that controlled hyperketonemia, or elevated blood ketones in healthy cows, could enhance metabolic efficiency. This suggests ketones act as an alternative energy source, helping to ease the metabolic burden of high milk production.

The economic impact is crystal clear. By implementing effective management that distinguishes between harmful ketosis and beneficial hyperketonemia, you can boost milk yield and herd health, enhancing your farm’s economic sustainability. This underscores the power of your vigilance and evidence-based strategies in maximizing productivity and minimizing losses.

Unveiling the Full Spectrum of Ketosis-Related Health Risks in Dairy Herds

Ketosis, though primarily a metabolic disorder, is closely tied to numerous health issues in dairy cows, including displaced abomasum, retained placenta, metritis, mastitis, and fatty liver syndrome. These ailments can significantly affect a cow’s health, lower milk production, and require costly veterinary care.

Such health problems disrupt milk production and decrease overall herd productivity. For example, a displaced abomasum often needs surgery and lengthy recovery, lowering milk output. Metritis and mastitis cut down milk yield and affect milk quality, sometimes making it unmarketable.

Cows with ketosis-related complications are more likely to be culled early, losing future milk production and causing the expense of replacing them. Thus, economic burdens arise from treatment costs, lost income, and the need for herd replacements, threatening the profitability and sustainability of dairy farming.

Navigating the Maze of Ketosis Research: The Imperative for Controlled Studies in Dairy Cow Health

Research on ketosis in dairy cows is extensive, driven by the need to manage this common metabolic disorder during the transition into lactation. While studies highlight the economic and health impacts of ketosis, there still needs to be a gap in fully understanding its complexities due to the prevalence of observational research. Much of the literature links ketosis to reduced milk production and increased health risks. However, these associations are often inconsistent and muddied by overlapping variables.

Observational studies help identify patterns but present significant limitations. They often need to control for confounding factors, making it hard to establish transparent causal relationships. Differences in farm management practices, genetic variations among cows, and environmental factors can all influence outcomes, complicating our understanding of ketosis’s true impact.

Controlled randomized experiments are the beacon of hope in addressing these limitations. These experiments offer a more rigorous investigation by eliminating confounders and isolating ketosis’s effects on health and productivity. The future of our knowledge of ketosis depends on adopting experimental designs that offer greater precision and reliability, providing more accurate insights and actionable recommendations for dairy farmers like you.

Revolutionizing Dairy Health: The Hidden Benefits of Ketones

Emerging research is now revealing the surprising benefits of ketones in dairy cows. Once seen only as markers of metabolic disease, recent studies, like those by Zhang and Ametaj (2020), suggest they have protective effects against metabolic dysfunction and chronic ailments. Ketones are not just indicators of an energy deficit; they are crucial health-promoting metabolites.

Ketones have been found to act as potent signaling molecules that reduce oxidative stress and inflammation, significant contributors to dairy cows’ metabolic diseases. These anti-inflammatory properties can significantly lower the risks of disorders during the transition period, thereby boosting cow health and longevity.

Additionally, ketones serve as alternative energy sources during glucose insufficiency, offering metabolic flexibility to maintain productivity, especially in early lactation when energy demands are high. This process helps balance energy use, reduce protein breakdown for glucose production, conserve muscle mass, and promote overall metabolic health.

This fresh perspective challenges the traditional view of hyperketonemia as purely pathological. It encourages a more comprehensive understanding of the potential health benefits of ketones. Integrating these insights can lead to innovative nutritional strategies and management practices that sustainably enhance dairy cow health and productivity.

Ketoacidosis Prevention: Practical Tips for Dairy Farmers

Preventing ketoacidosis is vital for maintaining dairy cow health and productivity. Here are some practical tips for dairy farmers:

The 340 cows at Philipsen Farms dairy near Lacombe, Alta., are milked three times a day. All are registered Holsteins.

With yearly losses at a staggering $65 billion, dairy cow illnesses are not just a local concern but a global economic crisis. The impact is felt in every corner of the world, from India to the United States to China and beyond. These losses disrupt milk production, lower fertility, and directly affect the livelihoods of countless farmers. This is not just a statistic but a pressing issue that demands immediate attention.

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.

Unlocking Holstein Fertility: How Genomic Daughter Pregnancy Rate Affects Postpartum Estrous

Monday, June 3rd, 2024

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.

GDPR and Estrous Activity: A Promising Connection for Dairy Herds

Parameter	High GDPR Cows	Low GDPR Cows	P-Value
Resumption of Estrous Expression (%)	62.0%	45.0%
First Insemination Pregnancy Rate (%)	48.0%	35.0%	<0.05
Pregnancy Rate for All Inseminations (%)	60.0%	50.5%	<0.05
Estrous Intensity (units)	3.2	2.8	<0.05
Estrous Duration (hours)	18.5	15.0	<0.01

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.

Integrating GDPR and Automated Activity Monitoring Systems: A Revolution in Dairy Management

Parameter	Cows with Greater GDPR	Cows with Lower GDPR
Intensity of Estrus	Higher	Lower
Duration of Estrus	Longer	Shorter
Resumption of Estrous Expression	Greater Proportion	Lower Proportion
Pregnancy per A.I. at First Insemination	Increased	Reduced
Incidence of Ketosis	Lower	Higher
Proportion Expressing Estrus Postpartum with Ketosis	Higher	Lower

Integrating GDPR and automated activity monitoring can revolutionize dairy management. Using the predictive power of genomic daughter pregnancy rate (GDPR) with activity monitors, farmers can significantly boost reproductive performance.

One key benefit is pinpointing cows with higher fertility potential. The study shows that cows with more excellent GDPR resume estrous activity in the early postpartum stage. This early detection enables timely insemination, shortening the interval between calving and conception. Automated systems enhance accuracy and reduce labor, ensuring insemination at optimal times.

Better reproductive performance means improved herd management. Higher pregnancy rates per A.I. and reduced pregnancy loss allow for more predictable calving intervals, aiding planning and stabilizing milk production.

Moreover, real-time health monitoring is another advantage. Cows with disorders like ketosis are quickly identified and managed, ensuring minimal impact on reproduction. Collected data informs nutritional and management adjustments during the transition period.

Combining GDPR and automated activity systems optimizes herd practices. By focusing on superior genetic and reproductive traits, farmers can enhance their herds’ genetic pool, leading to long-term productivity and profitability gains.

Ultimately, these technologies improve individual cow performance and offer a comprehensive herd management strategy, empowering data-driven decisions and enhancing operational sustainability.

The Bottom Line

The findings of this study show the crucial role of GDPR in improving reproductive outcomes in Holstein cattle. Higher GDPR is strongly linked to increased intensity and longer Duration of estrous activity in the early postpartum stage. This makes GDPR a reliable fertility predictor. By combining genomic data with automated activity monitoring systems, the dairy industry has an exciting opportunity to enhance herd management. Using these tools can boost fertility, improve health, and increase profitability. Adopting such technologies is vital for advancing reproductive management in dairy herds, ensuring the industry’s success and sustainability.

Key Takeaways:

The transition period in lactating dairy cows is critical, with 75% of diseases occurring within the first three weeks postpartum.

CNVs are vital in animal breeding and genetics, influencing traits from growth and milk production to disease resistance and reproduction. Understanding CNVs enables researchers to identify genetic markers for selecting animals with desirable characteristics, improving cattle health and productivity. Thus, CNVs offer a valuable toolkit for animal breeding, paving the way for more efficient and sustainable cattle farming.

Decoding the Genomic Puzzles of Holstein Cattle: A Deep Dive into CNVs and Their Impact on Vital Traits

The study embarked on a fascinating journey into the genetic complexities of Canadian Holstein cattle, with a specific focus on the impact of Copy Number Variants (CNVs) on reproduction and disease traits. The research team meticulously analyzed extensive genomic data, using a substantial sample size of 13,730 cattle genotyped with a 95K SNP panel and 8,467 cattle genotyped with a 50K SNP panel. To ensure accuracy, genome sequence data from 126 animals was also incorporated, leading to the identification and validation of CNVs. This concerted effort mapped 870 high-confidence CNV regions across 12,131 cattle, providing a comprehensive basis for linking CNVRs to critical reproductive and disease traits.

Advanced genomic techniques were employed to detect and confirm CNVs in Holstein cattle. Intensity signal files with Log R ratio (LRR) and B allele frequency (BAF) data were analyzed. LRR indicates duplications or deletions in the genome. At the same time, BAF distinguishes between heterozygous and homozygous states, which is essential for accurate CNV detection.

CNV regions frequent in at least 1% of the population were meticulously selected, ensuring only significant CNVs were included. This stringent process led to identifying 870 high-confidence CNVRs, paving the way for associating these CNVs with critical reproduction and disease traits.

Foresight and Hindsight. Don’t Blindside Your Fresh Cow Focus

· Comments (0)

Tuesday, April 8th, 2014

Foresight and hindsight are terms that are most often applied to strategic planning. When it comes to post calving transition, let’s consider them in the absolute sense meaning the “sight” your cows present post calving.

In this third part of our series on Transition Management, we are looking at the final stage. You are to be commended if you are already thinking, “The most important decisions I make for my fresh cows happen long before she calves out” or even before that when we set up our transition management program.” (Read more: Are Your Cows Ready For Their Close Up? and Dairy Cattle Management: LOST in Transition) That is so true but there are critical steps that must be acted upon to fulfil the post calving needs of your fresh cow too. Until cows and walls and stalls talk, your information must come from observation.

Observation doesn’t simply mean a quick check from across the barn, pen or pasture. What is needed is a full 360 degree close-up otherwise something important may be overlooked. Whatever you miss at this time could make the crucial difference between a successful lactation or it could mean culling the cow or, in the worst case scenario, death. The goal is to take what you see and apply it to a transition program that will make sure that fresh cows eat well and enter their lactation without health or metabolic issues such as metritis, mastitis, milk fever, ketosis or fatty liver. This is a situation where you can be assured that what you don’t see will definitely hurt you.

Setting Your Sightlines

Because the calving pen is an area of elevated stress and high turnover, it is important to set goals and corresponding benchmarks, in order to achieve the best outcomes. If benchmarks do not exist, set reasonable goals.

The first goal is to have nothing in the calving pen for longer than 24 hours. Longer stays result in dramatic increases in problems.
Milk Fever: 1%. Mature cows 2%. Seek help if over 3%.
Displaced abomasums. Less than 1% of all calvings. Seek help if 12%.
Retained placenta. Less than 8% of all calvings. Seek help if 10% or more.
Body Condition. During the first 30 days in milk, cows should not lose more than ¼ point body condition (120 lbs. body weight). This can have a huge effect on first service conception rate (50%).
Culling: Aim for less than 5% culling during the first 60 days in milk (DIM).

Improving your herd results on even one of these areas, could have a positive impact on the health of your cattle and your bottom line, while improving the day to day effectiveness of our cow care.

Fresh Cow Protocols Need the Right People and Protocols

Everyone who assists with calving should have training and possess the confidence to handle all pre and post calving protocols. Differences in how these protocols are carried out may cause problems. Even small details can have a positive or negative effect on your fresh cow program. Make sure that none of the following are overlooked: access to fresh water; immediate and plentiful access to high quality forage; attention to calving hygiene; follow-up if there has been calving trauma; consistently calm handling and dry, clean bedding at all times.

CSI: Cow Scene Investigations

You can’t fix what you don’t know is wrong. Every single dairy worker that interacts with the cattle must be trained to identify potentially sick cows. However, identifying them is only the beginning. The observations must be recorded. This enables a list of cows to examine or a system that flags which cows need an action. Recording of calving date, difficulties, disease findings and other relevant information needs to be maintained and accessible for decision making. Early identification and prompt treatment has a positive impact on the health and welfare of the fresh cow and also on culling and loss of production.

Note the Obvious First

There are obvious events in fresh cow transition management that must trigger immediate action.

Down cow
Difficult calving
Twins
Extremely fat cows at calving
Obvious discomfort of difficulty moving.

Foresight: It’s What’s Up Front that Counts

Having dealt with the obvious or emergency symptoms it’s time to look closer at the following areas:

Appetite: Note if cows are not eating, sorting or are not interested in feed at all. Check for undisturbed feed remaining in front of the cow at lock up. Before releasing cows from lockups, check for cows that have eaten less than their neighbors.
Attitude: Healthy animals are aware of their surroundings. Their ears are moving and they show curiosity. Sick animals tend to have their heads down, droopy ears, dull eyes and are too tired to groom their noses. Cows that are depressed react slowly to stimulus.
Eyes: Cows whose eyes appear sunken, dull or crusty may be dehydrated, or in pain, or both. Note if there are visible eye lesions, pink eye or trauma.
Ears: Sick animals have ears that are droopy. This could indicate that she is depressed, in pain or has a fever. Cold ears indicate decreased blood flow to the periphery which could be related to milk fever, acidosis or sever toxicity.
Nose: Abnormal discharge (white, green, yellow or bloody)may indicate pneumonia or acidosis. When sick cows don’t clean their noses and will have feed particles and nasal discharge sticking to their noses. It is also important to check if the nostrils appear dry, as this may indicate fever.
Cough ; Cows who are coughing repeatedly should be noted for observation.

Hindsight: Don’t Be Blindsided by the Backside

Abnormal Udder: Excessive udder swelling strongly suggests the need for revision of the dry cow feed program and perhaps that cows are not getting enough exercise.
Diarrhea: Diarrhea can be a symptom of improperly balanced dry cow ration or moldy feed.
Lameness: Lameness usually indicates that feet need cared for or that cows are having to walk and stand in wet manure.
Manure: Check the floor, vulva and tail for abnormal manure: too loose to form a pile; almost black in color and or foul smelling. These indicate cows may be suffering from acidosis, digestive upsets, toxic disease or enteritis.
Retained Fetal membranes: Retained fetal membranes are not a health problem per se, but increase the risk for metritis. If you find retained fetal membranes, you should also look for abnormal vaginal discharge.
Vaginal discharge: It is normal to find vaginal discharge for up to two weeks after calving. However, dark red and foul smelling vaginal discharges are found in cases of uterine infection.
Abnormal abdomen: Cows with their left flank tucked in have poor rumen fill because of anorexia. If the abdomen is distended, cows may be bloated due to rumen gas accumulation.
Breathing rate: The basal respiration rate is 12 to 36 breaths per minute. Note if the animal has abnormal respiration rate or if inspiration and/or expiration require additional efforts, pneumonia, bloat and toxic diseases may be causing the difficulty breathing.

Take ACTION. Fix the PROBLEM. Avoid causing New Ones.

After thorough observation, all is lost if the appropriate action is not taken. Quiet handling of fresh cows is the first step in moving them into a healthy lactation. If a fresh cow is on the identified list, the appropriate action must be taken. For those without specific health needs, all quarters should be milk out using good technique and consistent protocols. Poor methods here could cause problems. Here too is the place to make sure that correct diet has been formulated post calving. The grain feeding rate of each freshly calved cow is ramped up gradually over the first 5-7 days post calving. Many dairy operations are considering or have installed individual cow ID feeding systems. A fresh cow requires many nutritional components. Consulting with veterinary or nutritional consultants can take into consideration many variables including fresh feed availability, facilities, stocking density and handling expertise to name a few.

The Benefits of a Well-Conceived Transition Program.

There are two main facts to keep in mind. Fresh cows have the greatest production potential in a dairy. Having said that, fresh cows are very susceptible to diseases. Therefore, losses associated with illness, lameness or injuries are expensive. It is worth noting that 15% to 25% of all cullings take place during the first 60 DIM. If these losses can be reduced or eliminated, there are distinct financial rewards. Every step in transition is important but don’t let down at the end.

The Bullvine Bottom Line

By applying foresight, hindsight and attention to detail regarding all aspects of fresh cow management, the dairy manger will, at worst, end up with a list of shortcomings or, at best, find an incisive way of making proactive decisions. Either way the new insights are well worth it. Foresight? Hindsight? It’s time you looked at cows from all sides now! Set your sights on success!
