Have you ever pondered over the best housing strategy for your calves? The choice between individual calf hutches and group housing is more than just a matter of preference; it can impact everything from calf health to farm productivity. In the dynamic world of dairy farming, finding the most suitable housing approach for your calves is more crucial than ever. Do you know which strategy could be a game-changer for your farm?

Why Individual Calf Housing Stands the Test of Time 

Do you ever wonder why so many dairy producers continue to use individual calf housing? Despite various innovative ways, individual calf hutches remain the most popular technique. Let’s look at the historical context and present appeal of this technique.

Individual calf hutches a method that has stood the test of time since their inception in the 1960s, have been the preferred choice. They revolutionized cattle farming by significantly reducing disease transmission. Their simplicity and effectiveness have made them popular across the United States and Canada. For many years, hutches have been considered the gold standard in calf housing.

Consider the instance of Chris, a dairy farmer in Wisconsin. He has utilized individual hutches for more than 30 years. “I’ve tried various approaches,” he admits, “but I always return to hutches. They’re just more dependable in disease control.” With all these advantages and practical examples, it’s no surprise that individual calf hutches are popular among dairy producers. However, is this the most excellent solution for your farm? Only you can make the decision.

Pros of Individual Calf Housing

  • Disease Control: Individual calf hutches reduce the transmission of illnesses such as diarrhea and pneumonia, which may be severe in group settings. Research shows that calves raised in individual housing had a decreased frequency of these disorders.
  • Flexibility: Individual housing enables calves to be readily transported, and the system may be expanded as required. This flexibility is a significant advantage for many manufacturers that value the capacity to adjust fast. Hutches provide unparalleled flexibility, particularly for increasing operations.
  • Reduced Suckling Between Calves: Individual housing prevents calves from indulging in unwanted habits like sucking on each other’s ears or navels, which may cause infections and other health problems. According to behavioral research, solitude reduces risk and improves health outcomes.

Cons of Individual Calf Housing

  • Isolation: Calves reared in separate hutches experience social isolation, which affects their general well-being. Calves are naturally sociable creatures, and peer contact promotes natural behavior and social learning. Isolating calves might lead to poor social skills and difficulty adjusting to group situations later.
  • Delayed Cognitive Development: Being reared in seclusion may impede cognitive development. When exposed to new challenges and circumstances in a social context, calves tend to adapt better and learn faster. Research shows calves raised in pairs have better cognitive performance and adaptability.
  • Exposure to Extreme Temperatures: Individual hutches may expose calves to adverse weather conditions. These hutches may get very hot in the summer and uncomfortably chilly in the winter.
    • Summer: Ventilation, such as laying bricks beneath hutches or building windows and air vents, may help reduce heat accumulation. Offering cover in outdoor places may help shield calves from direct sunlight.
    • Winter: Hutches placed inside shelters can protect calves from severe winds and extreme cold. Proper bedding and insulation may also help keep the interior temperature steady.

Why Group Calf Housing is Gaining Momentum 

More dairy farms are moving to group calf housing, and this trend shows no signs of stopping. So, why is shared housing becoming so popular?

Cattle group living has numerous advantages, including increased work efficiency, faster development, and better socialization. Feeding and maintaining calves in groups may greatly minimize labor time, particularly with automated milk-feeding systems that enable calves to feed just when necessary, providing timely nourishment.

Calves kept in groups often exhibit robust development patterns. They grow weight more effectively and flourish in a social setting, with data revealing that they gain more weight daily than individuals living alone. Early social contact prepares calves for life in the herd, lowering stress levels later in development. When calves interact with their peers from an early age, they acquire the social skills required for group life.

Pros of Group Calf Housing

  • Labor Efficiency: Grouping calves may significantly minimize the work necessary to manage individual calves. Automated feeding systems help to simplify the procedure. Labor is decreased, and calves get milk when they are most in need of it.
  • Better Socialization: Calves in group housing demonstrate better social behavior, preparing them for group living later in life. The most prominent effect is increased social engagement. The calves play together and stimulate one another.
  • Automated Feeding Systems: These systems guarantee that calves get milk when required, reducing the need for human intervention and increasing efficiency. Thanks to automated milk-feeding devices that are now well-known and widely employed in the industry, feeding calves in groups has also become more accessible.
  • Strong Growth and Health Metrics: Calves in groups frequently have higher average daily growth and weaning weights. According to a University of Wisconsin-Madison research, group-housed calves outgrew individually-housed calves by a wide margin.

Cons of Group Calf Housing

  • Increased Disease Risk: When one calf becomes unwell, the illness swiftly spreads to others. This is a significant problem in group housing environments when contact is unavoidable.
  • Ventilation Challenges: Ensuring sufficient air quality is critical since poor ventilation may quickly spread respiratory problems. Calves lack the body heat to encourage adequate airflow, resulting in a stagnant environment prone to illness.
  • Temperature Control Issues: Without sufficient ventilation, stable temperatures are impossible to maintain, which has a severe influence on calf health, particularly during extreme weather conditions.

However, there are practical solutions to mitigate these issues: 

  • Positive Pressure Tubes: Positive pressure ventilation systems may provide fresh air into the house while preventing drafts. Fans attached to tubes offer a continual flow of clean air, which improves air quality.
  • Multiple Small Buildings: Housing calves in numerous smaller, narrower buildings improves disease control. This method encourages an all-in/all-out management attitude, making it more straightforward to control breakouts and maintain proper ventilation.

Pair Housing: The Perfect Balance Between Individual Hutches and Group Pens 

Pair housing is a practical compromise between individual calf hutches and group pens. This strategy has significant advantages over completely isolated or group-based systems. Farmers may encourage positive social contact in calves early on by placing them in pairs, which aids their cognitive and emotional development. This strategy enables the calves to interact with one another, which is vital for their well-being and social development.

Furthermore, findings show that calves housed in pairs had a higher average daily growth and weaning weight than their individually housed counterparts. This form of housing helps calves to consume more and gain weight more efficiently, better preparing them for the subsequent phases of development. Pairing calves may integrate effortlessly into current systems without requiring significant resource changes, making it a viable option for farmers.

Despite its benefits, pair dwelling has yet to reach widespread appeal. Producers may need to be made aware of the advantages of encouraging social behaviors or may still be concerned about calves suckling from one another despite evidence showing this is a minor problem when nutritional demands are addressed sufficiently. Pair housing as a feasible strategy might bridge the gap between the rigorous separation of individual housing and the complete management needs of group housing, resulting in a realistic and balanced approach to calf raising.

Let’s Talk Dollars and Cents: How Does Each Housing Method Stack Up Economically? 

Let’s talk dollars and cents. How does each housing method stack up economically? 

Initial Setup Costs 

  • Individual Housing: Individual hutches often need more materials and land area, resulting in greater starting expenses. An essential calf hutch may cost between $250 and $500.
  • Group Housing: Although the initial investment in infrastructure, such as positive pressure tubes and automated feeds, may be significant, group housing systems benefit from economies of scale. A barn for group living may cost $1,000 to $3,000 per calf area. Still, it may accommodate many calves under one roof.
  • Pair Housing: Pair housing falls halfway in the middle, splitting expenditures between individual and group settings. The initial cost comprises customized pens or dual-purpose hutches priced between $400 and $700.

Ongoing Maintenance 

  • Individual Housing: Maintenance expenditures here might quickly pile up. Each hutch must be cleaned and sanitized regularly, and the bedding should be replaced often. Individual feeding and care are labor-intensive, which might result in considerable labor expenditures.
  • Group Housing: Maintenance expenditures are often cheaper per calf. Automated feeding systems decrease labor, while centralized cleaning systems improve sanitation efficiency. However, modern ventilation systems may involve continuing running costs.
  • Pair Housing: Maintenance is often manageable. While it requires customized care, similar to hutches, having just two calves per unit allows for more efficient feeding and cleaning than individual setups.

Potential Financial Benefits and Drawbacks 

  • Individual Housing: The primary economic advantage is illness control, which saves major veterinary expenditures. However, excessive labor and maintenance costs might reduce profit margins.
  • Group Housing: Group housing provides significant financial advantages, including lower labor costs and the possibility for higher growth rates owing to improved socialization. However, the potential of disease transmission might result in significant losses if not controlled appropriately.
  • Pair Housing: This strategy creates a balance by lowering labor while promoting improved calf growth and social development. While not as cost-effective as group housing, it may still provide a good return on investment by boosting overall calf health and growth rates.

The Verdict: Which Calf Housing Method Wins?

Harnessing Technology to Revolutionize Calf Housing: A Game Changer for Dairy Farmers  

Technological improvements have considerably influenced calf housing in recent years, providing remedies to some of the conventional disadvantages of solo and group housing approaches. Let’s look at some of these technologies and how they may help your business.

Automated Feeding Systems 

  • Precision and Consistency: Automated milk feeders guarantee that calves get accurate quantities of milk regularly, lowering the danger of malnutrition or overfeeding. This is particularly useful in group living, where tracking individual consumption might be problematic.
  • Labor Efficiency: Automating the feeding process may save farmers substantial time and effort, enabling them to concentrate on other vital activities. This may be a game changer for both individual and group living situations.
  • Health Monitoring: Many automatic feeders have integrated health monitoring systems that follow the calf’s eating habits and inform farmers of any discrepancies that might suggest a health problem. Early diagnosis allows for quick treatment, minimizing illness transmission in group situations.

Advanced Ventilation Solutions 

  • Positive Pressure Ventilation: Positive pressure tube systems may bring fresh air into the dwelling area without causing drafts. This technique guarantees that air is circulated effectively, eliminating impurities and lowering the danger of respiratory disorders, which is critical in both individual hutches and group pens.
  • Climate Control: Advanced ventilation systems may be used with climate control technology to maintain ideal temperatures inside housing units. This is especially beneficial for managing high temperatures, typical in individual hutches exposed to the outside.
  • Air Quality Management: These devices can continually check air quality, ensuring that dangerous gasses like ammonia are preserved at acceptable levels, benefiting the calves’ general health and development rates.

Integrating these technology innovations into your calf housing systems may result in a more efficient, healthier, and productive environment for your livestock. Whether you choose individual hutches, group pens, or a mix, these technologies provide significant advantages that may improve your operations and calf care.

Ready to Make the Switch? Here’s How to Transition Smoothly to a New Calf Housing System 

  • Evaluate Your Current System: Carefully analyze your living arrangements before adjusting. Identify your talents and shortcomings. Are sickness rates greater than you would prefer? Is labor efficiency a concern? Create a list of what works and what does not.
  • Research the New Method: Obtain extensive information regarding the new housing technique you’re considering. Watch webinars, read case studies, and talk to other farmers. The Dairyland Initiative at the University of Wisconsin-Madison provides suitable materials.
  • Plan the Layout: Consider how you will arrange pens to maximize airflow if transitioning from individual hutches to group living. Also, consider feeding stations, a water supply, and space available for each calf.
  • Start Small: Initially, test the new procedure on a smaller number of calves. This allows you to discover and address any abnormalities without jeopardizing the health of your whole herd.
  • Upgrade Your Ventilation System: Ensuring enough ventilation can prevent illness transmission in group situations. Positive pressure ventilation systems are an affordable solution.
  • Staff Training: Educate your staff about the new system. Proper handling, feeding regimens, and disease monitoring must be revised to accommodate the new housing type.

How Dairy Farmers Can Benefit from Embryo Surrogacy

Boost your income with embryo surrogacy. Could renting your cows’ uteruses be your farm’s following ample cash flow?

Summary: Embryo surrogacy offers a promising way for dairy farmers to earn extra income by using dairy cows as surrogate mothers for beef cattle embryos, solving the beef industry’s excess embryo problem and achieving higher conception rates. Farmers benefit from premium prices for these calves, potentially boosting the commercial beef herd and requiring excellent management. In Ohio, Jake Osborn and his son Wyatt partnered with a dairy farm, turning leftover embryos into six live newborns, showcasing this method as a viable extra cash source.

  • Dairy cows can be surrogate mothers for beef cattle embryos, turning a surplus problem into a profitable solution.
  • Utilizing dairy cows for embryo surrogacy can yield higher conception rates compared to traditional methods.
  • Farmers receive a premium price for embryo calves, offering a potential boost in income.
  • This practice can contribute to rebuilding the commercial beef cattle herd in the U.S.
  • Successful implementation requires excellent management and knowledge of nutrition and calf care.
  • Innovative collaborations, like the one between Jake Osborn and an Ohio dairy farm, demonstrate the viability of this method.

What if I told you that your dairy farm might make additional money by “renting out” its cows? Yes, you read it correctly. Consider your cows as surrogate moms. The current income trend for dairy farms is to get into embryo surrogacy, a relationship that offers high financial rewards. Intrigued? You should be. “Right now, there are so many more embryos sitting in tanks than sitting in cows,” said show stock photographer J. Brad Hook, host of the “Genuine JBH” podcast.

From Manure to Methane: The Creative Ways Dairy Farmers are Cashing In 

Have you ever wondered how dairy farmers generate additional money besides selling milk? They are investigating new income sources, such as making composted manure a viable commodity for gardeners and farmers. It benefits the environment as well as their pocketbook.

Then there’s the increase of beef-cross calves. Farmers are capitalizing on the increased demand for meat by mating dairy cows with beef animals. These crossbred calves are reasonably priced, offering another revenue stream.

Not to add, some farms are becoming innovative with their resources. Consider producing methane-powered energy from cow poo! These farms are decreasing waste and lowering energy costs, with some even selling excess power back to the grid.

Have You Ever Thought About Renting Out Your Cows’ 

Have you ever wondered how dairy farmers make extra money besides selling milk? They are looking at additional revenue streams, such as making composted manure a marketable item for gardeners and farmers. This helps both the environment and their wallets.

Then there’s a surge in beef-cross calves. Farmers are capitalizing on the rising demand for meat by breeding dairy cows with beef animals. These crossbred calves are affordably priced, providing another money source.

Furthermore, some farms are becoming very resource-efficient. Consider generating methane-powered energy from cow dung! These farms are reducing waste and cutting energy costs, with some even selling extra energy back into the grid.

But you might be wondering why the beef industry needs this innovation. 

But you may be asking why the meat market needs this innovation.  According to J. Brad Hook, the supply of embryos has far outpaced the availability of beef recipient animals, particularly in today’s high-dollar-value beef sector. “Recip cows are now too costly to acquire. Custom beef recipient herds are fully booked and have significantly raised their rates owing to the worth of the animals,” he said.

Jake Osborn, a club calf producer from Lynchburg, Ohio, also contributes, emphasizing the financial benefits of this relationship. “At my location, a 20-30% fertilization rate on embryos was very normal, which is not favorable to producing money,” Osborn told me.” “Currently, we’re running 55-70% conception in the dairy cows, which is way better on IVF embryos than I’ll ever do at my house.”

Furthermore, Osborn highlights the practical advantages for dairy producers. “The dairy is capable of synchronizing a huge number of recipes simultaneously. “You can get a whole string of calves from the same mating, born just a few days apart,” he stated.

Embryo surrogacy is a possible answer to some of the beef industry’s most urgent issues, particularly the high cost and scarcity of meat-recipient cows. J. Brad Hook summarized it: “Right now, there are so many more embryos sitting in tanks than in cows.” This novel strategy has the potential not only to ease those concerns but also to generate new cash for dairy producers.

Jake Osborn’s Creative Collaboration: Turning Dairy Surrogacy into a Profitable Venture 

Jake Osborn’s collaboration with an Ohio dairy farm demonstrates the possibility of embryo surrogacy to improve dairy profitability. Osborn and his son Wyatt worked with an 800-cow dairy to repurpose leftover embryos. Beginning with a small experiment of nine embryos, they produced six live newborns owing to the dairy’s synchronized breeding cycle and strict care for the cows’ health.

Osborn stressed the benefits of cooperating with the dairy farm, citing a substantially higher conception rate—55-70% vs 20-30% on his farm. The dairy’s success stems from its precision breeding procedures. The resultant calves had no difference in development or conformation from their dam-reared counterparts, demonstrating the attentive care given by the dairy workers, whom Osborn rewarded with incentives depending on the calves’ selling price.

Financially, the venture was profitable for both sides. The dairy earned a much higher price for the embryo calves than for its beef-cross calves, giving a consistent extra cash source. Meanwhile, Osborn successfully brought excellent embryos to life, providing buying families with gentler, well-handled show calves ideal for young handlers. This partnership demonstrates how innovation in agricultural operations may result in win-win situations for all parties involved.

Why Embryo Surrogacy Could Be Your Farm’s New Cash Cow 

The advantages of using embryo surrogacy for dairy producers like yourself are many and considerable. One of the key advantages is that dairy cows have more excellent conception rates than average beef recipients. You may wonder why conception rates are crucial. Higher conception rates result in more successful pregnancies, calves, and, eventually, more money.

Furthermore, you may charge higher fees for calves born from these embryos. Osborn said the dairy earns more than the already healthy $800–$900 per head for beef-cross calves. This assures a consistent and profitable revenue stream, providing a valuable financial buffer to your conventional dairy business. It’s all about maximizing each cow’s potential in your herd, increasing their value.

So, if you’re seeking a strategy to increase your farm’s profitability and efficiency, embryo surrogacy might be the creative option you’ve been looking for. It’s a win-win scenario, with more results for the same work.

The High-Quality and Family-Friendly Calves Emerging from Embryo Surrogacy

The calves born via embryo surrogacy have shown exceptional quality and demeanor. Regarding development and conformation, Osborn’s calves are indistinguishable from those raised in dams. This high level of quality is mainly due to the meticulous care given by the dairy’s outstanding caretaker, who ensures that the calves flourish and achieve high standards.

Furthermore, the temperament of these show calves has proven beneficial. Families that purchase these calves are especially impressed with their gentle attitude and willingness to lead, making them perfect for young caretakers. Osborn pointed out, “You can buy one for your 10-year-old without worrying about them getting hurt.” This temperament difference provides customers with peace of mind and distinguishes surrogate-born calves.

If You’re Wondering About the Bottom Line, Let’s Break It Down 

If you’re curious about the bottom line, let us break it down. Traditional beef-cross calves cost a reasonable $800-900 per head. However, the cost of embryo surrogacy is much higher. Consider Osborn’s business, for example. His carefully nourished embryo calves fetch prices that exceed this baseline, often at a premium to conventional procedures.

Let’s try some elementary math. The difference is startling if a typical beef-cross calf earns $850 on average and an embryo calf earns $4,000-$5,000 per head. Even at a lesser cost of $4,000, the income is over five times higher (4,000 / 850 = around 4.7). Multiply this by 150 calves, and your potential profits rise from $127,500 to an impressive $600,000. That’s before you factor in any extra expenditures.

The price per calf isn’t the only important aspect here; teamwork also results in more excellent conception rates and simplified operations. This increased efficiency and premium pricing make embryo surrogacy a feasible and perhaps transformational option for your dairy farm.

Weighing the Risks: Challenges Every Dairy Farmer Should Know About Embryo Surrogacy

Of course, every opportunity has its own set of problems and hazards. Embryo surrogacy is no exception. Let’s start with the initial investment expenses. While the rewards might be substantial, starting up may need a considerable initial investment. You will need to acquire high-quality embryos, which are not inexpensive. Not to mention the expenditures associated with hormonal synchronization and veterinary care. This may make some farmers afraid to enter this terrain.

Then, there’s the requirement for specialized expertise. If you’re considering embryo surrogacy, you should be prepared to learn new skills or employ someone who already does. The technological know-how used during embryo implantation may significantly impact the success rate. It’s not just about implanting an embryo in a cow; it’s about doing it correctly to increase your chances of a healthy pregnancy.

During the procedure, complications may emerge. Even with experienced hands at work, conception rates may be a problem. Mistakes in hormone delivery or timing might result in unsuccessful implantations. Furthermore, if the receiving cow has stress or health concerns, it may undermine the whole operation. Calves may not flourish as predicted, introducing another degree of danger. Embryo transfer is both an artistic and a scientific process.

The Sky’s the Limit: Unlocking New Horizons with Embryo Surrogacy 

Looking forward, the possibilities for embryo surrogacy business options are endless. Consider bespoke raisers that specialize in raising embryo calves from birth and developing them into high-quality show cattle. This might be game-changing for purebred cattle ranchers looking to expand their herds without the trouble of controlling pregnancies.

Another promising option is to use dairy cows to help restore the commercial beef cattle herd in the United States. Did you know the nation’s beef herd is now the lowest it has been in over 70 years? Dairy cows calving out beef embryos may provide a much-needed remedy. This methodology might increase beef output by giving a more consistent and efficient means of herd growth.

These prospects don’t simply benefit the cattle business. They’re also a lifeline for dairy farmers wanting to diversify their revenue sources in an age when every dollar matters. So, why not pursue this novel path? Your farm might be at the forefront of a whole new specialized industry in agriculture.

The Bottom Line

For dairy producers, diversifying revenue sources is more important than ever. From innovative methane-powered energy to beef-cross calves, new avenues are opening up for extra money. Embryo surrogacy, the newest game-changer, benefits the dairy and meat sectors. By taking advantage of dairy cows’ natural reproductive cycles, you may pay a premium over market prices for embryo calves. Consider how this may fit into your organization after seeing how Jake Osborn is benefiting from it. It’s not only about making additional money but also maximizing resource use and increasing the commercial beef cattle herd. Consider renting out your cows’ uteruses since this might be an untapped specialty.

Lomira, Wisconsin, is the sole place that offers precise pricing for heifer calves. New Holland, Pa., has the most fantastic range of beef-cross calves, showing strong market demand.

What’s Driving the Soaring Heifer and Calf Prices? The Triple Threat You Need to Know About

The recent spike in dairy heifer and calf prices can be attributed to three critical factors: 

Hot Weather 

Hot weather has an evident influence on dairy output. High temperatures cause cow heat stress, which drastically reduces milk output. Numerous studies support this occurrence; for example, a University of Minnesota research indicated that heat stress may reduce milk supply by up to 10-30% [University of Minnesota Extension]. Reduced milk yields reduce supply, raising prices.

Avian Influenza 

Although avian influenza predominantly affects poultry, the effects extend across the cattle industry. The viral epidemic has led to increased farm biosecurity measures, restricting the movement of livestock such as heifers. The USDA states that “stringent quarantine and containment measures can indirectly affect various livestock industries.” This reduces the availability of replacement heifers and strains market supply systems.

Scarcity of Replacement Heifers 

The lack of replacement heifers is a major cause of rising pricing. Replacement heifers are critical for ensuring ongoing milk supply; without them, existing herds would age without new animals to take their place. According to USDairy’s current statistics, replacement heifer availability has decreased by around 15% from the previous year. Scarcity and increased demand have increased market prices for available heifers and calves.

The Bottom Line

As we’ve seen, the sky-high prices for dairy heifers and calves reflect a persistent tendency in the dairy business. The market has produced possibilities and problems for farmers throughout the country owing to extreme weather conditions, an avian influenza epidemic, and a lack of replacement heifers. The pricing dynamics are altering, with Holstein springers commanding upwards of $3,000 per head and beef-cross calves selling at high prices.

The T.C. Jacoby Dairy Market Report emphasizes the importance of these issues, predicting that tighter supply and strong demand will continue to define future estimates. This is a critical time for dairy producers to examine their operations. How will these skyrocketing costs affect their bottom line? Can their farm respond to these market changes? Navigating these concerns will be critical for dairy producers’ planning for the next months.

The research discovered that 22.8% of pre-weaned calves had BRD, significantly affecting herds. This number is critical for determining the disease’s prevalence. The average BRD incidence density rate was 0.17 cases per calf-month at risk, with a 95% confidence range ranging from 0.16 to 1.74. These findings illustrate the need for good management strategies to control BRD in dairy calves. Given that roughly a quarter of the calves in the research were impacted, BRD presents a severe clinical and economic problem to dairy producers. Implementing effective health monitoring and intervention measures may lower the incidence of BRD and enhance herd health. The variety in BRD cases, which is impacted by seasons, weather, and farm operations, highlights the significance of tailoring remedies to each dairy farm. Understanding these subtleties may result in more effective illness management techniques.

Strategic Measures for Reducing BRD in Preweaned Calves: Best Practices for Dairy Farmers 

Effective management practices are crucial in reducing BRD in pre-weaned dairy calves. This study identified several key strategies that are beneficial across various dairies. 

  • Firstly, feeding protocols are vital. Calves-fed waste or saleable milk had a much lower BRD risk than those given milk replacers. Additionally, providing more than 3.8 liters of milk daily to calves under 21 days old promoted a healthier start.
  • Bedding management also proved significant. Frequently changing the bedding in maternity pens reduced BRD risk. This simple practice minimizes calves’ exposure to harmful pathogens in soiled bedding, fostering a cleaner environment.
  • Vaccination protocols were crucial, too. Administering modified live or killed BRD vaccines to dams before calving significantly lowered the likelihood of their calves developing BRD. This proactive approach ensures calves receive antibodies through colostrum shortly after birth, offering early protection. 

By implementing these targeted feeding strategies, diligent bedding maintenance, and strategic vaccination schedules, dairies can effectively reduce BRD and promote the overall health of their pre-weaned calves. This combination of practices offers a comprehensive approach to managing factors contributing to BRD, safeguarding the productivity and longevity of dairy herds.

Identifying and Mitigating Key Risk Factors Influencing BRD Incidence in Preweaned Calves 

Several main risk factors increase the prevalence of bovine respiratory disease (BRD) in pre-weaned calves, which dairy producers should be aware of. Housing conditions are critical; calves in wooden hutches with metal roofs are more vulnerable than those in all-wood hutches, emphasizing the necessity for optimal shelter construction.

Additionally, twin births raise the chance of BRD. Twin calves are more likely to experience stress and have a lower immune system. These calves need further care and monitoring.

Environmental dust levels can have a significant impact. Dust that occurs “regularly” in the calf-raising region has been linked to an increased risk of BRD. Maintaining a clean, dust-free atmosphere is critical.

Seasonal differences can influence BRD occurrence. Summer and spring provide more significant hazards than winter, implying that warmer weather increases calves’ susceptibility to respiratory infections. Dairy producers should use season-specific measures to control and minimize BRD risk during peak incidence times.

Seasonal Patterns and Their Influence on BRD Incidence in Preweaned Calves 

SeasonBRD Incidence Rate (Hazard Ratio)95% Confidence Interval (CI)
Summer1.151.01 to 1.32
Spring1.261.11 to 1.44
Winter1.00Reference

The study’s results on seasonal effect show significant connections between time of year and BRD incidence in pre-weaned calves. Spring and summer provide a higher risk than winter, with hazard ratios of 1.26 and 1.15, respectively.

Spring’s shifting temperatures and increasing humidity might produce settings favorable to respiratory infections, reducing calf immunity. Furthermore, increased calving during spring results in more immature, fragile calves, increasing the danger of BRD epidemics.

Summer brings increased temperatures and the possibility of dust, which may irritate the respiratory system and make calves more vulnerable to illness. Heat stress during this season may further weaken calves, making it difficult for them to fight respiratory infections.

In comparison, winter often provides a more stable atmosphere. The colder temperatures may not have the same negative impact as those in spring and summer. Recognizing these trends enables tailored therapy depending on seasonal obstacles, lowering BRD risks throughout the year.

Proactive Strategies for Dairy Farmers to Combat BRD in Preweaned Calves 

Bovine respiratory disease (BRD) is a significant threat to pre-weaned calves. Research provides critical steps for dairy farmers to tackle this issue: 

  • Housing Improvements: To reduce BRD risk, use all-wood hutches instead of wooden cabinets with metal roofs. Ensure proper ventilation to minimize dust, linked to a higher incidence of BRD. 
  • Feeding Practices: Feed calves more than 3.8 liters of milk daily, especially those under 21 days old, to lower BRD risk. Milk replacers should be preferred over waste or saleable milk for better calf health. 
  • Maternity Pen Management: Frequently change maternity pen bedding to create clean and dry conditions, reducing exposure to pathogens and lowering BRD transmission.
  • Vaccination Protocols: Administer modified live or killed BRD vaccines to dams before calving to boost calf immunity via colostrum, protecting against respiratory infections
  • Addressing Twin Births: Extra care is crucial for twins, who are at higher risk for BRD. Ensure they get sufficient nutrition and monitor them closely for respiratory issues.
  • Seasonal Considerations: BRD risk is higher in spring and summer. To prevent infections, enhance feeding protocols, and increase monitoring during these seasons. 

By adopting these strategies, dairy farmers can significantly reduce BRD risk, ensuring healthier calves.

The Bottom Line

Our study of BRD in pre-weaned dairy calves provides essential insights for minimizing its prevalence. By examining management techniques and risk variables, we offer a clear path for California dairy producers to improve calf health and production. Key results from the BRD 10K trial include:

The Science Behind Happy Cows: Emotional States and Personalities in Dairy Management

Discover how management practices impact the emotions and personalities of dairy animals. Can better welfare lead to higher productivity? Explore the latest research.

The dairy business depends heavily on the welfare of its dairy cows. Good animal welfare and a high quality of life influence their health, productivity, and lifetime. The adage “Happy animals are productive animals” summarizes this connection well. Positive emotional states cause cows to produce more milk, effectively procreate, and improve general farm efficiency.

This paper delves into the crucial relationship between management techniques and dairy cows’ emotional states. Understanding and measuring these states is key to tailoring strategies that create favorable surroundings, thereby enhancing the conditions for animals and the business. The focus is on minimizing negative emotional states from demanding circumstances and maximizing good moods in supportive settings.

“Investing in a farm environment and management techniques that support cows’ positive emotional states is finally an investment in long-term health and productivity.”

We will discuss techniques and scientific developments in the emotional evaluation of dairy cows. Behavioral, cognitive, and physiological markers help us grasp how on-farm settings affect these states. This understanding is crucial for improving animal welfare and building more sustainable and profitable dairy farming operations.

The Evolving Landscape of Animal Emotions and Personalities 

Advances in animal behavioral research are driving a changing awareness of animal emotions and personalities. Once mostly seen from a functional standpoint, animals are now known to have distinct personalities and complicated emotional terrain. These elements greatly influence their behavior, health, and production, so animal welfare and farm efficiency depend on identifying and encouraging pleasant emotional experiences.

Measuring these feelings, however, might provide difficulties. Researchers must depend on indirect techniques because animals cannot express their mental states. Early research concentrated on visible actions, which in context might be deceptive. To help with this, scientists have developed complex behavioral, cognitive, and physiological approaches.

Behavioral tests of emotional states include body language changes such as posture, movement, and facial expression. Cognitive bias studies reveal animal emotional valence and expectancies by showing how they link stimuli with positive or negative consequences. These experiments show that mood reflects decision-making just as human decisions are shaped by optimism or pessimism.

Calves’ anticipatory behaviors—anticipating rewards—provide information on their emotional states and environmental sensitivity. Such assessments highlight the importance of stimuli that boost good mental involvement and lower stress or dissatisfaction.

Like infrared thermography, physiological techniques track variations in body temperature linked with emotional arousal and stress. Decision-making tasks in animals, including goats and chickens, expose preferences and aversions, thus mapping their emotional terrain. These physiological signals provide objective information to complement cognitive and observational results.

Combining these approaches can enhance our understanding of animal emotions and personalities despite measurement challenges. Based on current developments, improved animal welfare and management techniques can create environments where animals can thrive emotionally and physiologically, offering a promising future for dairy farming.

Innovative Methodologies for Gauging Dairy Animal Emotions

Researchers have used creative techniques like cognitive bias tests to determine dairy cows’ emotional states. These experiments show how management decisions, including calf presence or absence, affect cow emotions (Neave et al., 2023; Neave et al., 2024). Presenting animals with conflicting cues allows researchers to deduce whether the animals are in happy or negative moods. Still under research, body language analysis also hints about cows’ emotional well-being based on tail movement and ear placement.

Anticipated behavior emphasizes the emotional reality of dairy animals. When awaiting a reward, calves in barren pens exhibit more active behavior than in wealthy settings; this contrasts with their calm reactions in the latter (Neave et al., 2021). This response emphasizes how much the surroundings affect emotional states.

Technologies have enabled techniques such as infrared thermography and decision-making challenges. In pigs (Franchi et al., 2024), infrared thermography tracks variations in body temperature connected to stress and alertness. Tasks related to decision-making, such as those investigated in goats and chickens (Garnham et al., 2022), expose animal preferences for situations that coincide with their emotional well-being.

Understanding the Profound Impact of On-Farm Management on Dairy Animal Emotional Well-Being

They enhance welfare and productivity, which hinges on comprehending how on-farm management impacts the emotions of dairy cows. Cognitive bias tests and body language studies suggest that cows and calves exhibit more pleasant feelings together, while separation induces stress, compromising their health and productivity. This underscores the crucial role of the living environment.

Improved surroundings help with emotional and physical wellness. Calves housed in enriched pens show reduced stress levels, more pleasant emotional states, and more favorable responses to incentives. Studies incorporating infrared thermography and decision-making exercises support animals’ preference for environments that maximize their comfort.

Customizing management to suit specific personalities can further enhance welfare and productivity. For instance, while scared animals might struggle in competitive situations like eating, exploratory animals might adapt well during weaning. Understanding these traits can pave the way for more personalized, efficient management plans.

These findings underscore the importance of considering dairy cows’ emotional and personality aspects. By improving welfare, we can enhance production and health. The adage’ Happy animals are productive’ continues to guide us towards ethical agricultural practices, armed with the knowledge and tools to make a difference.

Exploring the Interplay Between Animal Personality Traits and Management Practices 

Good management techniques depend on an awareness of how personality features affect animal behavior. Curiousness, anxiety, and aggressiveness greatly influence responses to various management situations. Curious dairy calves, for instance, boost their development and health by managing to wean better, adjust faster to new meals, and exhibit less stress.

Under competitive feeding, fearful dairy goats typically avoid the feed bunk, which results in inadequate nutrition. This emphasizes the requirement of stress-free feeding surroundings to provide enough nourishment for shy animals.

Bold dairy cows explore new feeds and regions, enhancing their nutrition and general health. They also graze more and produce more milk.

Understanding these behavioral patterns enables one to customize management strategies to fit personal requirements, thus optimizing comfort, stress reduction, productivity, and welfare enhancement in surroundings.

Insightful Research on Emotional Welfare and Management Strategies 

Neave et al. (2023) used cognitive bias tests to investigate how calf separation affected the emotional well-being of dairy cows. According to the results, cows housed with calves exhibited less stress, more satisfied behavior, and a more positive cognitive bias. This emphasizes the need to keep mother ties to improve the emotional well-being of dairy cows.

Neave et al. (2021) conducted another investigation into calf anticipatory behavior enhanced against barren pens. Calves raised in enriched surroundings exhibited more marked anticipatory behaviors when anticipating benefits and less irritation when such incentives were denied. Improved living arrangements help enhance mental wellness and lower stress in dairy calves.

Studies using decision-making activities and infrared thermography to grasp environmental preferences in dairy cows provided yet more insights. Garnham et al. (2022) and Franchi et al. (2024) showed the efficacy of these techniques in evaluating emotional states in pigs and hens, respectively. Changing these approaches may help optimize dairy farming methods for improved animal well-being.

Studies of personality qualities also clearly affected managerial relationships. According to Neave et al. (2018), more adventurous dairy calves did better around weaning, adjusting rapidly, and displaying faster growth rates. Understanding individual personalities may enhance managerial results.

According to Neave and Zobel (2020), less scared dairy goats were likelier to enter feeding areas under competition, influencing their nutritional intake and health. By considering individual variances, better management strategies to lower competition-related stress may be created.

These studies emphasize how enhancing well-being depends on an awareness of dairy cows’ emotional and personality aspects. Customizing farm settings to fit group and personal requirements may produce more content, better quality, and more efficient dairy herds.

Practical Applications for Dairy Farmers to Enhance Animal Well-Being 

Practical applications for dairy farmers to tailor management practices to meet the individual needs of their animals are essential. These strategies can enhance the emotional well-being of dairy animals and foster a more positive, productive farm environment: 

  • Individual Care: Develop protocols that address specific personality traits. Exploratory calves, for instance, benefit from enriched environments that stimulate curiosity and ease weaning stress.
  • Environmental Enrichment: Provide various enrichments such as different forages, toys, and brushes to promote natural behaviors and reduce boredom.
  • Consistent Rewards: Implement a predictable routine with consistent rewards to develop positive anticipatory behaviors, especially in calves housed in diverse pen types.
  • Temperature Control: Use infrared thermography to monitor and control environmental conditions, ensuring comfort and reduced stress.
  • Behavioral Monitoring: Observe and record behaviors regularly to detect emotional changes. Adjust handling practices based on whether an animal is fearful or aggressive.
  • Feeding Strategies: Adapt feeding based on animal personalities. Provide shy or less dominant goats with alternative feeding times or spaces to reduce stress.
  • Engagement and Training: Use decision-making tasks and gentle handling training to build trust and reduce fearfulness, reinforcing desirable behaviors.

By implementing these strategies, dairy farmers can create an environment that meets individual animal needs, leading to better health, reduced stress, and improved milk production. This commitment supports a thriving and sustainable dairy industry.

The Bottom Line

The paper underlines the need to know and evaluate dairy cows’ emotional states and personalities. Essential instruments to assess emotional well-being under various management settings include behavioral, cognitive, and physiological approaches, including cognitive bias tests, anticipatory behavior analysis, and infrared thermography. We also examined how curiosity, fear, and assertiveness affect production and well-being.

One should invest in knowing these emotional states and personalities. This improves long-term production, health, and animal welfare. The proverb “happy animals are productive animals” underlines the significance of good farm surroundings.

Constant research is vital. Better animal life circumstances and advantages for farmers will be guaranteed by ongoing scientific research and scientifically based solutions.

Key Takeaways:

Simplify Scours Prevention: Effective Strategies for Calf Health and Management

Simplify scours prevention with focused strategies for calf health. Discover actionable tips to counter complex scours issues and boost your calf-care program.

Imagine the scenario: your calves, the cornerstone of your livestock operation, confront scours—a disruptive condition that can derail their health and growth. Preventing scours isn’t just about averting immediate illness; it’s crucial for the long-term vitality of your herd. 

Environmental and nutritional stressors like weather changes or feeding inconsistencies can trigger scours. Pair that with pathogens such as E. coli, coronavirus, and salmonella, and the challenge intensifies. Notably, rotavirus is present in about 75% of scours cases and makes calves more vulnerable to additional infections like cryptosporidium and respiratory issues. 

“Investing in scours prevention isn’t just a protective measure; it’s a strategic move to ensure your herd’s future. By focusing on targeted antibodies and proven management practices, you can mitigate scours’ risks and impacts.” 

Through dedicated efforts, leveraging advanced antibody technologies, and strict management protocols, calf raisers can master the complexities of scours. These strategies significantly reduce scours incidents, promoting healthier and more resilient calves.

Decoding Scours: Unraveling the Multifactorial Health Crisis in Calves 

By definition, scours is a complex clinical symptom associated with multifactorial diseases that prevent the intestine from absorbing fluids and nutrients. Environmental and nutritional stressors along with a number of scours pathogens can ignite a scours event. While there are a handful of scours pathogens that play a harmful role – including E. coli, coronavirus, and salmonella – rotavirus is present in about 75% of scours cases. 

Rotavirus exacerbates the situation by increasing the likelihood of secondary infections, such as cryptosporidium, and significantly heightens the probability of requiring respiratory treatments before group pen movement. Additionally, while rotavirus symptoms in calves typically last five to seven days, the calf can continue to shed the pathogen into the environment for up to 13 days post-infection, thereby amplifying the contagion risk to other animals. 

The impact of scours on calf health and growth is profound. During the course of an infection, calves experience severe dehydration and nutrient malabsorption, which leads to stunted growth and increased vulnerability to other diseases. This can result in long-term developmental delays and a weaker overall immune system. 

Common signs and symptoms of scours in calves include watery or loose stools, dehydration, lethargy, sunken eyes, dry mouth, and a decrease in the interest of feeding. These symptoms not only affect the immediate well-being of the calves but also have lasting impacts on their overall health and productivity as they mature.

Unpacking the Scourge: Understanding the Multifaceted Threat of Calf Scours

Scours, a common affliction among calves, is fundamentally a complex clinical symptom characterized by a multifactorial disease structure that hinders the intestine from efficiently absorbing fluids and nutrients. The causative factors of scours are diverse, stemming from a combination of environmental and nutritional stressors and a variety of pathogens. Chief among these pathogens are E. coli, coronavirus, salmonella, and notably, rotavirus, which is implicated in approximately 75% of scours cases. 

The repercussions of scours on calf health and growth are profound. Calves infected with scours experience a significant depletion in their ability to absorb essential nutrients and fluids, leading to dehydration, reduced growth rates, and in severe cases, a considerable increase in morbidity and mortality rates. Specifically, calves suffering from rotavirus-associated scours are doubly susceptible to cryptosporidium infections and are 17 times more likely to necessitate respiratory treatments within the early stages of their life. Such infections not only exacerbate the immediate health decline but also contribute to long-term developmental challenges due to potential permanent damage to intestinal tissues. This damage impairs nutrient absorption, thus stunting growth and overall development. 

Identifying scours in calves hinges on recognizing its common signs and symptoms. These typically include diarrhea, which presents itself in a watery and often foul-smelling form, general signs of dehydration (such as sunken eyes and dry, pale gums), as well as lethargy and a noticeable decrease in feeding enthusiasm. Additionally, calves may exhibit signs of abdominal pain, evidenced by hunching or kicking at the belly. The duration of symptoms varies, generally lasting between five to seven days for rotavirus, though the pathogen can be shed into the environment for up to 13 days post-infection, complicating containment efforts and necessitating vigilant management practices.

Strategic Nutrition: Essential Practices for Scours Prevention

Effective strategies for preventing scours often revolve around optimized nutrition and feeding practices. Let’s delve deeper into critical nutritional aspects that contribute to scours prevention: 

Importance of Colostrum Intake for Immunity  

Colostrum is the calf’s first shield against scours, rich in antibodies that strengthen the immune system. Ensuring timely and adequate colostrum intake is crucial. High-quality colostrum fed soon after birth can significantly mitigate scours risks. 

Proper Milk Replacer Formulation and Feeding Schedule

When Does Heat Stress Impact Calves?

Discover when heat stress affects dairy calves and learn actionable strategies to protect their health and growth. Are your calves at risk? Find out now.

Contrary to a common but flawed assumption that calves can tolerate heat stress better than mature cows due to their unique physiological traits, Dr. Jimena Laporta’s extensive research has shed new light. Her findings reveal that the thermoneutral zone for calves closely mirrors that of adult cattle, ranging from 50-72°F. When ambient temperatures deviate from this optimal range, calves must expend additional energy to regulate their internal body temperature, compromising their growth and immune function. This article, grounded in Dr. Laporta’s research, will explore the factors influencing heat stress in dairy calves, such as their thermoneutral zones, age and size considerations, and the Temperature-Humidity Index (THI). We will also examine the regional variations in heat stress benchmarks between Florida and Wisconsin and propose practical strategies to alleviate heat stress and foster optimal calf growth.

Understanding Heat Stress: When Calves Are Most Vulnerable

Heat stress in dairy calves poses a significant threat not only to their immediate health but also to their long-term productivity. Contemporary research dispels the conventional belief that calves are inherently more resilient to heat stress than adult cows. 

Calves subjected to elevated temperatures face the challenge of redirecting energy from critical growth and immune functions towards thermoregulation, thereby stunting growth rates and heightening vulnerability to diseases. These early-life setbacks impair their development and adversely affect their future productivity as mature dairy cows

Multiple factors, including age, physiological status, and environmental conditions, play pivotal roles in influencing calf heat stress. Age significantly impacts thermoregulation, with younger calves lacking fully developed mechanisms. Physiological status, encompassing health and nutrition, affects heat dissipation and immune efficiency. Environmental conditions such as temperature, humidity, and wind speed exacerbate the stress, with high moisture particularly hampering cooling efforts. 

Prenatal exposure to heat stress predisposes calves to greater thermal sensitivity post-birth, underscoring the critical need for strategic management practices for dairy calves

Addressing heat stress in calves is imperative for holistic herd management, safeguarding future productivity, and ensuring sustainability. Effective strategies, elaborated in the practical tips section, include providing adequate shade, offering access to cool water, and implementing mechanical ventilation systems.

The Science Behind Calf Heat Stress: Key Thermoneutral Zones

It is a prevailing misconception that calves possess a heightened resistance to heat stress due to certain physiological traits. While they exhibit a greater surface area relative to their body mass, facilitating heat dissipation, this perceived advantage is counterbalanced by other factors. The underdevelopment of their rumens results in less metabolic heat generation, ostensibly offering an edge in heat management. However, empirical research reveals a more complex reality.  

Calves function optimally within a thermoneutral zone of 50-72°F. Deviations from this temperature range, whether towards the higher or lower spectrum, necessitate energy allocation towards thermoregulation, undermining growth and immune system efficacy.  

Grasping the repercussions of temperature fluctuations beyond this thermoneutral zone is imperative. Elevated temperatures trigger thermoregulatory responses, notably increased respiration and distinct behavioral adjustments. This redirection of energy comes at the expense of growth-critical reserves.  

The long-term implications of sustained heat stress are significant. Studies underscore discernible behavioral shifts in heat-affected calves, including alterations in standing and lying postures. These insights are instrumental in crafting effective heat mitigation strategies.  

Comprehending the specific thermoneutral requisites of calves is critical. Such awareness is pivotal in alleviating heat stress, thus nurturing healthier and more robust dairy calves. Environmental management and tailored heat reduction initiatives transcend mere operational tweaks; they are strategic investments in the enduring productivity and welfare of the herd.

Factors Influencing Calf Heat Tolerance: Age, Size, and Environment

In examining the intricate matter of calf heat tolerance, it becomes imperative to analyze the interconnected dynamics of several critical factors. Age and size hold significant sway. Younger and smaller calves frequently exhibit increased susceptibility to heat stress due to their immature thermoregulatory systems. Conversely, while older and larger calves may demonstrate enhanced resilience, they are not exempt from the challenges posed by extreme heat. 

Environmental parameters such as wind speed, ambient temperature, and relative humidity are pivotal in determining heat tolerance. Elevated wind speeds can facilitate heat dissipation, providing a cooling effect that mitigates high-temperature stress. However, ambient temperature is the primary driver of heat stress, with rising temperatures directly correlating with increased physiological strain on calves. Furthermore, high relative humidity exacerbates this issue by hindering the evaporation of sweat and respiratory moisture, thus compromising the calves’ natural cooling mechanisms. 

Integrating these factors allows for a more holistic approach to mitigating the adverse effects of heat stress on dairy calves. Recognizing the specific needs and limitations of calves across various growth stages and environmental conditions equips dairy farmers with the ability to implement more effective heat abatement strategies. This proactive approach ensures the sustained health and optimal performance of their livestock.

Temperature-Humidity Index (THI) and Its Impact on Calves

The Temperature-Humidity Index (THI) is a pivotal metric within the dairy farming sector, offering a nuanced understanding of how ambient temperature and relative humidity collectively impact livestock. Compared to ambient temperature alone, THI provides a more precise indicator of heat stress. Its relevance in dairy farming cannot be overstated, as it directly correlates with an animal’s capacity to maintain thermal homeostasis and achieve optimal physiological performance. For mature dairy cows, a THI of 68 is broadly recognized as the threshold at which heat stress begins, heralding the onset of thermoregulatory difficulties and subsequent declines in productivity. 

Nevertheless, Dr. Jimena Laporta’s extensive research elucidates that calves exhibit distinct THI thresholds. Her findings indicate that calves in Florida start showing significant respiratory changes at a THI of 65, with rectal temperature alterations appearing at a THI of 67. Conversely, calves in Wisconsin exhibit both respiratory and rectal temperature changes at a higher THI of 69. This research underscores that calves are markedly susceptible to environmental heat stress despite their supposed physiological advantages in heat dissipation. Consequently, there is a critical need to adopt tailored management practices that consider regional climatic disparities.

Regional Differences: Florida vs. Wisconsin Calf Heat Stress Benchmarks 

detailed examination of THI thresholds in Florida and Wisconsin reveals noteworthy differences in calf heat stress reactions. In Florida, calves exhibited sudden changes in respiratory rates at a THI of 65 and rectal temperatures at 67. Conversely, these indicators were noticeable in Wisconsin at a THI of 69. This data highlights the significant influence of regional climates on calf thermal tolerance.  

The broader ramifications for dairy farming are profound. Heat stress can substantially hinder calf development and their long-term performance. Heat-stressed calves often consume less milk replacer and starter grain, stunting their growth. Moreover, the research associates early-life heat stress with delayed conception and reduced milk yield in the first lactation, culminating in notable economic setbacks. As Laporta argues, addressing heat stress in calves is a strategic investment in the future productivity of the herd.  

Laporta and her team are investigating advanced methods for combating heat stress, including mechanized ventilation systems powered by solar panels for individual calf hutches. These innovations alleviate heat stress and adhere to sustainable agricultural practices. This dual advantage illustrates how contemporary technology can address traditional farming challenges.  

Dairy producers should provide sufficient shade to enhance calf well-being, ensure access to cool water, and employ cooling mechanisms such as fans and misters. Monitoring THI and adjusting practices accordingly can mitigate heat stress. It is imperative to consider regional differences to tailor strategies for specific environmental conditions.  

Investing in heat stress abatement for calves is essential for their immediate welfare and long-term herd management strategy. As Laporta emphasizes, “We are investing in our calves for life. Heat reduction should be one of those investments.” Prioritizing the thermal comfort of young dairy animals fosters robust growth, improved reproductive performance, and sustainable productivity, safeguarding operations against heat stress challenges.
