Calf health and slow-release milk replacers

The rearing of healthy calves is essential for the long-term productivity of dairy farms. One critical aspect of calf rearing is nutrition, with milk replacers playing a vital role in providing essential nutrients to young calves. Traditionally, milk replacers have been fed in multiple daily feedings, mimicking the natural nursing behavior of calves. However, there is growing interest in exploring alternative feeding methods, such as slow-release milk replacers, to potentially improve calf health and overall farm efficiency. This article delves into the effects of slow-release milk replacer feeding on calf health.

Traditional Calf Feeding

Traditionally, calves are fed milk replacers in several daily feedings, usually two or three times a day. This method attempts to replicate natural nursing patterns, where calves nurse from their dams multiple times throughout the day. While this approach can be effective, it demands a significant amount of labor and management resources. Additionally, abrupt changes in feeding times can cause stress to the calves, potentially impacting their health and growth.

Slow-Release Milk Replacers

Slow-release milk replacers are designed to provide a more constant and consistent supply of nutrition to the calf. These formulations are engineered to gradually release nutrients over an extended period, typically 8-12 hours. This method aims to mimic the slower nutrient absorption rate calves experience when nursing from their mothers, potentially reducing stress and promoting healthier calf development.

Effects on Calf Health

  1. Improved Digestive Health: Slow-release milk replacers can promote better digestive health in calves. The gradual release of nutrients may reduce the risk of digestive upsets, such as diarrhea, which can be common in young calves.
  2. Reduced Stress: Calves can experience stress when they anticipate feeding times or when subjected to abrupt changes in feeding schedules. Slow-release milk replacers can help reduce this stress, contributing to improved overall calf health.
  3. Enhanced Growth: While more research is needed to confirm this effect, some studies suggest that calves fed with slow-release milk replacers may experience more consistent growth rates. This could result from improved nutrient absorption and reduced stress.
  4. Efficient Resource Utilization: Farm efficiency is another crucial factor to consider. Slow-release milk replacers require fewer labor-intensive feedings, potentially reducing labor costs and enabling better resource allocation on the farm.

Challenges and Considerations

While slow-release milk replacers show promise in improving calf health, several factors should be considered:

  1. Cost: Slow-release milk replacers may be more expensive than traditional milk replacers. Farmers should evaluate the cost-effectiveness of adopting this feeding method.
  2. Management: Proper management and monitoring are essential when implementing slow-release milk replacers to ensure that calves are receiving adequate nutrition.
  3. Research Gaps: More research is needed to fully understand the long-term effects of slow-release milk replacers on calf health, growth, and production.

Slow-release milk replacers offer a novel approach to calf feeding that has the potential to improve calf health and farm efficiency. By providing a more consistent nutrient supply and reducing stress, these formulations may contribute to healthier calves and more robust dairy operations. However, it is essential for farmers to carefully assess the cost-effectiveness and suitability of slow-release milk replacers for their specific circumstances and to stay informed about the latest research and best practices in calf nutrition.

Are you raising your dairy heifers to their full potential?

Most dairy farmers want to operate their farms profitably, and we know that one of the pillars of dairy farm profitability is getting as much milk output from each cow as feasible. One of the most important aspects in that trip is how heifers are cared for, and if they calf before the age of two, they are more likely to have a large lifetime productivity.

Large lifetime output does not come easily, and achieving that aim for the herd is a significant task.

We’ve seen far too frequently that heifers aren’t the farmer’s priority, at least not until they give birth and develop into cows. This error is probably more widespread than many people realize. But we also know that if a heifer is not properly raised, the chances of her developing into a highly productive and long-lasting cow are slim.

I often tell farmers that they should treat their heifers like the money-making machines they can be in the future, particularly during the initial months of her life. Here, we construct the farm’s future cow.

Holstein’s full potential

A suitable Holstein heifer with a normal genetic background has the DNA necessary to produce a high-yielding cow. When she is born, her DNA is set for high production, but you might say that after that, our main task is to try to make sure she can get full usage of that potential. Small errors in rearing will be seen in the yield, thus it is critical to concentrate on the heifer and her well-being.

Of course, there are several methods for raising heifers, as well as numerous methods for monitoring their progress. Farmers may use a variety of KPIs to monitor how things are going, but one KPI in particular provides a wealth of information for me: daily weight growth.

Cow weight growth on a daily basis

What the daily gain should be varies per farm and, of course, depends on the dairy breed, but for Holstein heifers, any daily increase less than 850 grammes per day should give the farmer cause to reconsider management. The essential point here is that the farmer sets a daily development goal and follows through on it. Without a doubt, any mistakes in the heifer’s rearing will have an impact on daily development. Slow average development right initially indicates certain management concerns, such as a poor environment, sickness, improper nutrition, and so on. As a result, frequent weighing will rapidly disclose whether anything is wrong with heifer management.

I’m not advocating that all heifers be weighed all the time, but recording daily growth will provide valuable information. It is simplest to weigh the calves upon birth, and there are various basic methods for doing so; any simple industrial scale will suffice. Then, when the heifer is old enough, I always urge farmers weigh it again at weaning and provide the correct quantity of concentrate or TMR. With these two measures, it is simple to compute her daily growth in the first few months of life. This time represents the cow’s future; if she has made solid and strong leaps forward with correct development, she is already more likely to become a nice cow at this point.After the calf has been weaned

After weaning, there is a sensitive time in which growth frequently decreases. This is most usually caused by improper weaning, in which the milk was not appropriately supplemented with excellent concentrate or TMR. Weighing heifers at 4 months is a difficult chore, particularly if there are a lot of them, therefore I would not encourage it. However, keeping note of the height is a simple approach to keep track of the development here. This may be accomplished by painting a stripe on the inventory so that it is simple to tell how high they are while eating. Of course, if it is feasible, it is ideal to weigh them and monitor their development until they are hefty enough to be inseminated in time to give birth before they are two years old.

The most important factor, though, is that the farmer concentrates on growth and correctly monitors and measures it. It is up to each farmer how they do this, but I can guarantee that everyone who does so will be on the way to higher dairy farm outcomes.

Coccidiostats as a tool for preventing coccidiosis in calves

Coccidiosis is a common and potentially devastating parasitic disease that affects young calves in the cattle industry. Caused by protozoan parasites of the genus Eimeria, coccidiosis can lead to severe intestinal damage, weight loss, and even death if left untreated. To combat this threat and ensure the health and well-being of young calves, farmers and veterinarians often turn to coccidiostats. In this article, we will explore the importance of coccidiostats in controlling calf coccidiosis and how they work.

Understanding Calf Coccidiosis:

Coccidiosis primarily affects young calves during the first few months of life. The disease is highly contagious and is often spread through contact with infected feces or contaminated environments. Once ingested, the Eimeria parasites multiply within the calf’s intestines, leading to symptoms such as diarrhea, dehydration, lethargy, and a decrease in weight gain. Left untreated, coccidiosis can result in significant economic losses for cattle farmers.

The Role of Coccidiostats:

Coccidiostats are chemical compounds specifically designed to control and prevent coccidiosis in cattle. They play a crucial role in managing the disease, especially in intensively managed calf rearing systems. Coccidiostats work by inhibiting the growth and reproduction of Eimeria parasites in the calf’s gastrointestinal tract.

Key Advantages of Coccidiostats:

  1. Disease Prevention: Coccidiostats are effective at preventing coccidiosis outbreaks in susceptible calf populations. When used prophylactically, these compounds help maintain the overall health and productivity of the herd.
  2. Improved Growth Rates: By controlling coccidiosis, coccidiostats promote better weight gain and feed efficiency in calves. This results in faster growth and reduced economic losses for farmers.
  3. Reduced Environmental Contamination: Coccidiosis is transmitted through feces, and infected calves can contaminate their surroundings. Coccidiostats help reduce environmental contamination, decreasing the likelihood of future infections.
  4. Minimized Treatment Costs: Treating coccidiosis in affected calves can be expensive and often less effective than preventive measures. Coccidiostats offer a cost-effective approach to disease control.

Types of Coccidiostats:

There are two main types of coccidiostats used in calf management:

  1. Ionophores: Ionophore coccidiostats, such as monensin and lasalocid, alter the permeability of the parasites’ cell membranes, disrupting their ability to maintain proper ionic balance. This interference hinders the reproduction of Eimeria, reducing their impact on the calf.
  2. Chemical Coccidiostats: Chemical coccidiostats, like amprolium, work by inhibiting the metabolism of Eimeria parasites. They disrupt the energy production process within the parasite, limiting their growth and reproduction.

Calf coccidiosis remains a significant concern in the cattle industry, particularly in intensive calf rearing operations. Coccidiostats, whether ionophores or chemical compounds, play a pivotal role in preventing and controlling this parasitic disease. By incorporating these coccidiosis control measures into calf management practices, farmers can improve the health and growth rates of their young calves while minimizing economic losses associated with coccidiosis outbreaks. It is essential for cattle producers to work closely with veterinarians to develop effective coccidiosis prevention and treatment strategies tailored to their specific operations.

The 7 Deadly Reproduction Sins That Are Costing Your Dairy Farm

Reproductive efficiency is a critical factor in the success of any dairy farm. Efficient reproduction ensures a steady supply of replacement heifers and a productive milking herd. However, some common mistakes or “reproduction sins” can hinder the reproductive performance of your dairy farm, leading to wasted time, decreased profitability, and potential long-term problems. In this article, we will explore these reproductive sins and discuss how to address them for the benefit of your dairy operation.

  1. Inadequate Record-Keeping

    Efficient reproduction management begins with accurate record-keeping. Failing to maintain detailed records of breeding, calving, and health events can lead to confusion and missed opportunities for improvement. Ensure your records include essential information such as breeding dates, pregnancy checks, and health treatments.

    Solution: Invest in a comprehensive farm management software or hire a dedicated record-keeper to maintain up-to-date and organized records.

  2. Delayed or Inconsistent Heat Detection

    Missing signs of heat or failing to detect them consistently can result in delayed breeding and lower conception rates. Heifers that are not bred in a timely manner may require more time and resources to reach productive milking age.

    Solution: Implement a rigorous heat detection program using tools like tail chalk, electronic heat detectors, or activity monitors to identify cows in heat promptly.

  3. Improper Nutrition

    Nutrition plays a vital role in reproductive success. Inadequate or imbalanced diets can lead to poor body condition, delayed estrus cycles, and reduced fertility.

    Solution: Work with a nutritionist to formulate appropriate diets for different stages of reproduction. Monitor body condition scores regularly and adjust feeding accordingly.

  4. Neglecting Herd Health

    Disease outbreaks can wreak havoc on reproduction rates. Failing to vaccinate against common reproductive diseases or providing inadequate healthcare can result in reduced fertility and increased veterinary costs.

    Solution: Develop a comprehensive herd health program with your veterinarian, including regular vaccinations, parasite control, and disease prevention measures.

  5. Poor Transition Program

    Any health condition after calving might have an impact on a cow’s fertility; even if she recovers completely, her reproductive health is likely to be impacted.

    Solution: Transition cow management ensures that animals remain healthy throughout their calving experience so that they can support their next pregnancy. It is critical to monitor fresh cows for transition concerns in order to guarantee that they will be able to calve again in the future.Monitoring their physical condition score is a crucial part of transition cow management.

  6. Ignoring the Importance of Genetics

    The selection of breeding sires is crucial for the genetic improvement of your herd. Ignoring genetic potential can lead to stagnant or even declining milk production over time.

    Solution: Collaborate with a geneticist or breeding specialist to choose sires that align with your breeding goals. Utilize genetic testing to make informed decisions.

  7. Inadequate Training

    Inefficient reproduction management can often be traced back to inadequate training for farm personnel responsible for breeding and reproductive health.

    Solution: Invest in ongoing training and education for your farm staff, ensuring they are up-to-date with best practices and the latest advancements in dairy reproduction.

Addressing these reproduction sins on your dairy farm can significantly improve reproductive efficiency, reduce wasted time, and enhance overall profitability. Regularly review and update your reproductive management practices, invest in staff training, and prioritize herd health to ensure a robust and productive dairy operation for years to come.

How Prefresh Diets Set the Stage for Colostrum Yield

The period leading up to calving is a crucial phase in a dairy cow’s life cycle. Proper nutrition and management during this time can have a significant impact on the cow’s health, milk production, and the health of her newborn calf. One essential aspect of this phase is the “prefresh diet,” a carefully formulated diet given to cows in the weeks before calving. In this article, we will discuss the importance of prefresh diets and how they set the stage for colostrum yield, a critical component of calf health.

The Role of Prefresh Diets

Prefresh diets are designed to prepare cows for the demands of calving and lactation. They serve several essential purposes:

  1. Energy and Nutrient Replenishment: During the late stages of pregnancy, cows’ energy and nutrient requirements increase significantly. Prefresh diets provide the necessary nutrients to meet these demands, ensuring the cow maintains proper body condition and is ready for calving.
  2. Metabolic Health: Prefresh diets help prevent metabolic disorders like ketosis and fatty liver syndrome, which can occur if cows enter calving in a negative energy balance.
  3. Colostrum Quality: Proper nutrition during the prefresh period directly impacts the quality and quantity of colostrum produced by the cow immediately after calving.

Colostrum Yield and Quality

Colostrum, the first milk produced by a cow after calving, is a rich source of essential nutrients and antibodies vital for the health and immunity of the newborn calf. The prefresh diet plays a significant role in determining the quality and yield of colostrum:

  1. Volume: Adequate energy intake from the prefresh diet ensures that the cow can produce an ample amount of colostrum. A well-fed cow is more likely to have a larger colostrum yield, which is crucial for the calf’s first feedings.
  2. Nutrient Content: The prefresh diet influences the composition of colostrum. It provides the necessary nutrients, including immunoglobulins, vitamins, and minerals, which are essential for the calf’s health and development.
  3. Antibodies: Colostrum is rich in antibodies (colostral antibodies or immunoglobulins) that help the calf establish immunity. Proper nutrition during the prefresh period ensures that the colostrum contains a sufficient concentration of these antibodies.
  4. Consistency: Consistent and balanced nutrition throughout the prefresh period reduces stress on the cow and helps maintain stable hormone levels, which are essential for colostrum production.

Optimizing Prefresh Diets

To maximize colostrum yield and quality, dairy farmers should consider the following when formulating and managing prefresh diets:

  1. Consult a Nutritionist: Work with a qualified nutritionist to formulate a balanced prefresh diet tailored to the specific needs of your cows and herd.
  2. Monitor Body Condition: Regularly assess the body condition of cows during the prefresh period and adjust diets as needed to maintain optimal condition.
  3. Minimize Stress: Reduce stressors in the prefresh environment, such as overcrowding or sudden changes in diet, as stress can negatively impact colostrum production.
  4. Provide Clean Water: Ensure cows have access to clean and fresh water at all times, as water intake is essential for colostrum production.

Prefresh diets are a critical component of dairy cow management, setting the stage for successful calving, lactation, and calf health. By providing cows with the right balance of nutrients and maintaining their overall well-being during this crucial period, dairy farmers can optimize colostrum yield and quality, ultimately contributing to the long-term success of their dairy operations.

Should you raise replacement heifers yourself?

The success of a dairy operation relies heavily on the quality and health of its herd. Replacement heifers, young female cows that will eventually join the milking herd, play a crucial role in maintaining and improving the herd’s productivity. The question of who should be raising replacement heifers is a vital one for dairy farmers. This article explores the various options and considerations for raising replacement heifers effectively.

  1. On-Farm Rearing

    • Cost: Initial purchase costs can be substantial.

The decision of who should be raising replacement heifers depends on your farm’s specific circumstances, goals, and resources. Each option has its advantages and challenges. Many successful dairy operations combine strategies, using on-farm rearing for some heifers and custom rearing or purchasing for others. Regardless of the approach, the key to success is diligent management, a focus on animal health and genetics, and maintaining a long-term vision for the sustainability of your dairy operation.

Robotic Milking: Technology, farm layout, and labor flow considerations

Cows in conventional herds follow a structured routine and receive all their nutrients from a total mixed ration, while cows in herds with robotic milking systems have the opportunity to be milked more frequently and fed more precisely, but there are challenges in maintaining a consistent milking frequency and finding the right balance of feed ingredients.

  • Since the first commercial systems appeared in 1992, automatic milking systems (AMS) have been installed at an increasing rate
  • In most cases, cows obtain all their nutrients from a TMR; in herds equipped with robotic or AMS, a fraction of their nutrients is provided during milking, mainly as a means to attract cows to the milking system, whereas the remaining fraction is supplied in the feed bunk through a partial mixed ration (PMR)
  • Opportunity from AMS resides in the possibility of milking more frequently, assigning different milking frequencies to different cows, and feeding cows more precisely or closely to their nutrient needs, potentially resulting in improved feed efficiency and economic returns rendering a more profitable production system than when using a single TMR
  • From a behavioral standpoint, free traffic conditions coupled with frequent deliveries of the PMR at the feed bunk and limiting concentrate allowance in the AMS to 3 to 4 kg/d seem more beneficial for milking cows in a AMS
  • Tremblay et al (2016) found a negative association between concentrate allowance in the AMS and milk yield, the same study reported a positive association between the percentage of feed allowance that was not consumed and milk production. This emphasizes that the potential advantages of feeding cows more closely to their nutrient needs are only achieved if the precision at which these nutrients are offered is high
  • Restricting concentrate allowance to <3 to 4 kg/d is recommended to maximize economic returns and minimize variation in nutrient intake
Table 1Feeding and milking behavior and milk production and composition of cows with free traffic versus guided traffic systems (Bach et al., 2009)

Early Onset Muscle Weakness Syndrome (HMW) in Dairy Cows: Causes, Symptoms, and Management Introduction

Early Onset Muscle Weakness Syndrome (HMW) is a significant concern in dairy farming, impacting the health and productivity of dairy cows. HMW is characterized by muscle weakness and trembling, leading to decreased milk production and potentially severe welfare issues for affected cows. This article discusses the causes, symptoms, and management of HMW in dairy cows.

Causes of HMW in Dairy Cows

  1. Nutritional Imbalance: One of the primary causes of HMW in dairy cows is an imbalance in their nutritional intake. This includes deficiencies in essential minerals and vitamins, such as selenium, vitamin E, and vitamin A. Insufficient intake or poor absorption of these nutrients can lead to muscle weakness.
  2. Mycotoxins: Contamination of feed with mycotoxins, such as aflatoxins and ergot alkaloids, can contribute to the development of HMW in dairy cows. Mycotoxins can impair muscle function and cause neurological issues.
  3. Genetic Predisposition: Certain dairy cattle breeds may be genetically predisposed to HMW, making them more susceptible to this condition. Breeding practices can influence the prevalence of HMW in a herd.
  4. Management Practices: Poor management practices, such as overcrowding, inadequate ventilation, and unsanitary living conditions, can create stress and increase the risk of HMW in dairy cows.

Symptoms of HMW in Dairy Cows

  1. Muscle Weakness: The hallmark symptom of HMW is muscle weakness. Affected cows may have difficulty standing or walking, leading to a wobbly gait and trembling muscles.
  2. Reduced Milk Production: HMW significantly reduces milk production in affected cows. This decline in milk yield can have economic implications for dairy farmers.
  3. Weight Loss: Cows with HMW may lose weight due to reduced feed intake and metabolic changes associated with muscle weakness.
  4. Difficulty Rising: HMW can make it challenging for cows to rise from a lying position, increasing the risk of injury and stress.
  5. Decreased Fertility: HMW can also impact fertility in dairy cows, leading to reduced conception rates and longer calving intervals.

Management and Prevention

  1. Nutritional Management: Ensuring a well-balanced diet for dairy cows is crucial. Regularly monitor and adjust feed formulations to meet the nutritional requirements of the herd. Supplement with selenium, vitamin E, and vitamin A as needed.
  2. Mycotoxin Control: Implement measures to prevent mycotoxin contamination in feed and forage. This includes proper storage, monitoring, and the use of mycotoxin binders when necessary.
  3. Genetic Selection: Consider breeding practices that minimize the risk of HMW by selecting cows less susceptible to this condition. Consult with veterinarians and geneticists to make informed breeding decisions.
  4. Environmental Conditions: Maintain clean and well-ventilated housing for dairy cows. Adequate space, hygiene, and comfort can reduce stress and the risk of HMW.
  5. Early Detection and Treatment: Regularly observe the herd for signs of HMW and seek veterinary assistance promptly if symptoms arise. Early diagnosis and treatment can improve the chances of recovery.

Early Onset Muscle Weakness Syndrome (HMW) in dairy cows is a multifactorial condition that can have detrimental effects on milk production, animal welfare, and farm economics. Dairy farmers should prioritize proper nutrition, mycotoxin control, and good management practices to reduce the risk of HMW in their herds. Genetic selection and early detection are also essential tools in managing this condition effectively. By addressing the causes and symptoms of HMW, dairy farmers can ensure the health and productivity of their cattle while maintaining a sustainable and profitable operation.

A faster ketosis detection technique

Ketosis is a metabolic state in which the body utilizes fat for energy rather than carbs. Individuals following low-carb diets, such as the ketogenic diet, typically seek this state, and it is occasionally employed as a therapeutic method for addressing specific health concerns. Those who want to attain and sustain ketosis must be able to detect it. Traditionally, this included time-consuming and inconvenient techniques such as urine test strips or blood tests. However, technological and scientific advancements have opened the way for a more easy and effective method of identifying ketosis.

The Importance of Ketosis Detection

Before getting into the new time-saving strategy for diagnosing ketosis, it’s critical to understand why this metabolic condition is important to monitor. Ketosis has various advantages, including:

  1. Weight Loss: Ketosis may help you lose weight by pushing your body to burn stored fat for energy.
  2. Enhanced Mental Clarity: While in ketosis, several people experience increased attention and mental clarity.
  3. Blood Sugar Stability: Ketosis may help stabilize blood sugar levels, which is especially advantageous for those with type 2 diabetes.
  4. Ketosis may lower hunger and desires, making it simpler to stick to a calorie-restricted diet.
  5. Improved Physical Performance: Ketosis may assist athletes and fitness enthusiasts by increasing endurance and fat utilization during activity.

Methods for Detecting Ketosis in the Past

Historically, the following procedures were used to identify ketosis:

  1. Urine Test Strips: The color of these strips changes depending on the concentration of ketones in the urine. While they are affordable and widely accessible, they are not always reliable and may not represent current ketone levels.
  2. Blood Ketone Meters: These instruments monitor ketone levels in the blood and provide more reliable findings than urine test strips. They do, however, need regular blood draws, which may be painful and inconvenient.
  3. Breath Ketone Analyzers: These gadgets detect the presence of acetone in your breath, which corresponds with ketone production. They are non-invasive, although they may be costly.

The New Time-Saving Technique

Continuous glucose monitors (CGMs) have been developed as a time-saving way for diagnosing ketosis as a result of emerging technology and study. CGMs, which were originally meant to monitor blood glucose levels in diabetics, have expanded to incorporate ketone monitoring capabilities. This approach works as follows:

  1. A CGM is a wearable device that comprises of a tiny sensor that you connect to your skin, usually on your belly. This sensor continually monitors the levels of glucose in the interstitial fluid under your skin.
  2. Dual Monitoring: Some CGMs can now monitor glucose and ketone levels at the same time. This dual monitoring provides a complete picture of your metabolic condition.
  3. CGMs give real-time data, which may be accessed through a smartphone app or other compatible devices. This enables you to keep track of your ketone levels throughout the day without having to do manual testing.

The Benefits of CGMs for Ketosis Detection

Using CGMs to detect ketosis has various advantages:

  1. Convenience: Because CGMs enable continuous monitoring, there is no need for repeated daily tests.
  2. CGMs provide reliable and real-time ketone measurements, lowering the possibility of erroneous results.
  3. Insights: Using continuous monitoring, you can see how your food, activity, and other things impact your ketone levels.
  4. CGMs, unlike blood ketone meters, do not need you to prick your finger.

Detecting ketosis is critical for those who follow a low-carb or ketogenic diet and want to get the related health advantages. While conventional approaches such as urine test strips and blood ketone meters were previously used, the introduction of continuous glucose monitors with ketone monitoring capability marks a major development in this sector. These gadgets provide a practical, time-saving, and precise approach for monitoring ketosis, offering vital insights into one’s metabolic condition. As technology advances, the use of CGMs for ketosis monitoring is anticipated to become more accessible and user-friendly, allowing people to maximize their dietary choices and general health.

How does dairy cow temperament affect milk production?

Milk production is a critical component of the dairy industry, and farmers constantly strive to maximize yields to meet consumer demand. While factors like genetics, nutrition, and herd management are well-known determinants of milk production, another often-overlooked aspect is the temperament of dairy cows. A cow’s temperament can have a significant impact on its overall health, stress levels, and, consequently, milk production. This article explores the connection between dairy cow temperament and milk production and highlights the importance of understanding and managing cow behavior in modern dairy farming.

Understanding Dairy Cow Temperament

Dairy cow temperament refers to an individual cow’s behavioral and emotional disposition. Just like humans, cows exhibit a range of temperamental traits, and these traits can vary from one animal to another. Common traits used to assess cow temperament include docility, aggression, fearfulness, and sociability. While these traits are partly influenced by genetics, they can also be shaped by environmental factors and the way cows are handled and managed.

The Impact of Temperament on Milk Production

  1. Stress Levels: One of the most significant ways in which cow temperament affects milk production is through stress levels. Cows that are more easily stressed tend to produce less milk. High-stress levels trigger the release of stress hormones, such as cortisol, which can suppress milk production. Stress can result from various factors, including aggressive interactions with other cows, noisy environments, or uncomfortable living conditions. Therefore, cows with calmer temperaments are often better milk producers.
  1. Feeding Habits: Dairy cow temperament can also influence feeding habits. Nervous or aggressive cows may struggle to access food in a group setting, leading to uneven nutrient intake. This can negatively impact milk production and overall cow health. Docile cows, on the other hand, are more likely to eat calmly and consistently, which is crucial for optimizing milk production.
  1. Reproductive Performance: A cow’s temperament can extend its influence to reproductive performance. Highly stressed or anxious cows may experience disruptions in their estrous cycles, leading to delayed or missed pregnancies. This can result in extended dry periods and reduced overall milk production.

Managing Dairy Cow Temperament for Improved Milk Production

To maximize milk production and overall herd health, it’s essential for dairy farmers to manage and improve cow temperament. Here are some strategies to consider:

  1. Select for Calm Temperament: When choosing replacement heifers or sires for breeding, consider selecting animals with calm temperaments. This can be done by evaluating the temperament of their parents and ancestors.
  1. Proper Handling and Training: Gentle and consistent handling from birth can help develop calm and sociable cows. Avoid aggressive handling or practices that can lead to fearfulness in young calves.
  1. Comfortable Living Conditions: Provide cows with comfortable and clean living conditions. Adequate shelter, space, and ventilation can reduce stress and promote a calmer temperament.
  1. Minimize Stressors: Identify and minimize stressors in the environment. This includes reducing noise, preventing overcrowding, and ensuring access to fresh water and food.
  1. Monitor Behavior: Regularly observe cow behavior and intervene when necessary. Early detection of issues like bullying or illness can prevent prolonged stress and decreased milk production.

Dairy cow temperament plays a vital but often underestimated role in milk production. A cow’s disposition can impact stress levels, feeding habits, reproductive performance, and overall well-being. By understanding and managing cow behavior, dairy farmers can optimize milk production, improve herd health, and ultimately increase the profitability of their operations. It is essential for the dairy industry to recognize the significance of cow temperament and incorporate temperament management strategies into their farming practices for sustainable and efficient milk production.

Managing a dairy herd just got easier with the aid of DeLaval Plus Behavior Analysis – the latest farm management tool which uses data sensors to record each animal’s behavior, analyzes each cow’s data using artificial intelligence (AI) and helps dairy producers identify sick cows and cows in heat.

The new system from DeLaval, a global leader in the dairy industry, can also track cows’ localization in the barn every second of every day, making it easier to find cows that need attention. Daily updates and real-time information delivered to farmers’ smartphones help them manage their to-do lists more efficiently and effectively.

“By responding to a cow quickly and with the right action, producers can drive the performance of their farm by increasing cow productivity and welfare,” said Joaquín Azocar, Solution Manager, DeLaval Farm Management Systems. “Producers with DeLaval Plus Behavior Analysis in their farm management toolbox have total visibility and oversight of their cows.”

The system works with new DeLaval BioSensor ear tags, which automatically communicate with nodes installed throughout the barn. The data is shared with DeLaval DeepBlue, an artificial intelligence-based software which analyzes the information using  sophisticated models of cow behavior. The system provides state-of-the-art heat detection, rumination and eating behavior calculations and returns this information to farmers in the form of actionable intelligence so they can make better, faster and more accurate decisions.

The Riddells, who milk 90 cows in Ontario, Canada, installed DeLaval Plus Behavior Analysis to help them take better care of their herd. “If the cow is not feeling well, the graph on the computer will tell us before we can see it,” said Jaclyn Riddell. Her husband, Travis, also noted that the AI-component takes herd management to the next level. “It’s looking behind the scenes and can find things quicker than we can,” he said.

As many farms struggle to find and retain skilled people, DeLaval Plus Behavior Analysis promotes a better work experience for farmers and their staff by taking the guesswork out of the equation. The tool, which is available with or without cow localization, can suit multiple barn layouts and reporting requirements.

Feed efficiency in dairy sire selection

Paying greater attention to feed efficiency indices while choosing sires for dairy herds would assist compensate for today’s growing feed prices.

With this in mind, dairy producers are being asked to investigate all possibilities to help reduce these high expenses, and a more focused and effective use of genetics is a fantastic instrument for doing so.

Two Holstein cows with the same productivity level may consume quite different amounts of grain.

According to one study, the more efficient cow ingested 861 kilos less dry matter than the other cow, resulting in a 12% decrease in feed expenditures.

What exactly is a feed efficiency index?

Dairy producers may employ sires that breed cows as better feed converters by choosing genotypes with a high index for feed efficiency.

This means cows produce more milk and meat on less feed while maintaining high health, reproductive performance, and a long productive life.

This contributes to the company’s profitability and long-term viability.

The feed efficiency index measures how efficiently a cow converts grain into milk. While some cows are adept at this, others use excessive amounts of feed for upkeep and are inefficient in terms of feed utilization.

The creation of a credible index for feed efficiency requires direct and precise measurements of each cow’s feed intake in a large number of nursing cows under the predicted performance circumstances.

Cows bred by bulls with a high feed efficiency index use fewer feed resources because they transform feed more effectively and need less energy for upkeep.

This implies that resources are being utilized more effectively, and dairy producers are able to produce more milk and meat with less inputs, lowering the environmental impact.

Decoding feed efficiency indices: five crucial questions for making educated decisions

When examining feed efficiency indices, a farmer should ask his or her genetics representative five simple questions.

Is data acquired from commercial herds with varying production methods and management levels collected without interfering with cows’ natural behavior and daily farm routines?

Because herds have diverse production techniques and management levels, data should be gathered from a variety of farms to provide a more trustworthy index.

Is the feed intake data recorded on lactating cows?

Some genetic firms provide data gathered from heifers. Pryce et al. (2014) discovered a genetic association of 0.67 between heifer and first lactation cow efficiency. This suggests that heifer efficiency accounts for just 45 percent of the variance in cow efficiency. This makes the usefulness of registering heifers to forecast cow efficiency exceedingly wasteful.

Is feed intake monitored during the lactation and throughout the lifespan of the cow?

The physiology and productivity of a cow alter drastically throughout lactations. Feeding needs and performance vary depending on the stage of lactation. As a result, data from all periods of the cow’s life should be obtained.

Does the index allow for breeding for improved feed efficiency while minimizing the effect on productivity, health, and fertility?

Breeding merely to conserve feed is insufficient since output levels must be maintained to ensure farm profitability. Farmers must be cautious while breeding for more feed efficient cows and avoid favoring animals that exhaust their body reserves for milk output.

Does the feed efficiency index take metabolic efficiency into account?

Metabolic efficiency is an important component of feed efficiency since it assesses how efficiently the cow converts feed energy in her body. This is energy that is utilized to promote milk production, for example.

Advantages of the Feed Efficiency Index

Because more feed efficient cows emit less methane, breeding for increased feed efficiency helps lessen the environmental effect of the dairy and beef sectors.

It is critical to limit the environmental effect of each dairy farm. And if the farmer can do this by making relatively easy changes in the genetics used in the herd in order to minimize the quantity of feed that cows consume and waste generated while maintaining the required production level, this results in more efficient farming.

Jan Lassen, MSc., PhD, Senior Research Manager at VikingGenetics, a Nordic genetics firm owned by cattle breeders in Denmark, Sweden, and Finland, encourages farmers to examine the significance of the Saved Feed Index, which is part of the Nordic Total Merit index.

“Improving efficiency through breeding is a win-win situation.” “We increase production by selecting the most efficient animals,” Mr Lassen said.

“There are no negative effects on health, reproduction, or longevity.”

The Saved Feed Index is based on information from the Cattle Feed Intake technology (CFIT), a cutting-edge technology that uses three-dimensional cameras and artificial intelligence to recognize cows, evaluate their weight, and quantify how much they consume.

CFIT delivers real-time data for each cow’s feed intake recorded in the cow’s natural surroundings year round, backed by more than nine years of research and development.

1,300,000+ lactating cow daily intake records
12,000 or more cows with CFIT data 1,000,000 or more feed visits per day

By including the Saved Feed Index into the breeding aim, dairy producers get a valuable tool for optimizing their operations and meeting the criteria for sustainable food production.

 

You can’t turn off dairy cow stress

Stressors resource center helps shed light on its complexities

How do you save energy? That’s easy. Turn off the lights. Unfortunately, when it comes to dairy cow stress, it’s not that simple. You can’t turn off stress that easily.

Stress is caused by stressors. We recognize more than 30 different stressors that can affect the health and performance of a dairy cow. However, if you read through dairy-related articles, you may realize that the industry tends to focus only on a small handful of stressors and address each of them individually. Your reality at the farm level is that stressors interact with each other and compound, negatively impacting cow health, performance, reproduction and longevity.

Dairy cow stress is complicated. Knowing how stressors work and how they affect your cows will help you reduce their negative impact on your herd — and improve your revenue.

The concept of stress and strain

Domesticated food animals are prey species. When they perceive a threat, their instinct is to avoid a predatory attack. Things are different under modern farming conditions since cows have very little risk of being eaten by a predator. Today, a perceived threat (stressor) comes from different sources and often leads to metabolic strain. As a result, your cows will make a physiological or behavioral change to maintain balance.

A key step is to understand that each cow handles these changes differently. During the Jefo RumiNation Podcast Impacts of Stress and Strain on Reproductive Health (Series 3, Episode 6), Dr. Matt Lucy, professor at the University of Missouri, said it’s important to know the difference between stress and strain. “All cows are stressed, but the strain is how the cow responds to that stress. For example, we have a lot of cows in a herd that make 100 pounds of milk per day. The stress is the production. However, the strain is how she responds to that. We want our cows to have very little strain.”

According to Dr. Lucy, the amount of strain determines the impact stress will have on production and fertility. Genetics can help as it allows a producer to select for a more resilient cow. “We want cows that can handle these stresses,” says Dr. Lucy. “Once we have the right kind of cows, then, as a producer, you have to manage the remaining strain. You cannot fix everything with genetics — you have to be a top producer and manage the remaining strains like heat stress, nutrition, bunk space and so forth.”

The key is to identify the stressors that are having the biggest impact on you, your cows and your team, and then incorporate solutions to reduce the strain they cause.

Know stress, no stress

You know the old adage: Knowledge is power. Knowing more about stress helps eliminate the effects of stress. Jefo Nutrition has outlined five key stress categories and identified solutions to help keep cows comfortable, healthy and productive:

· Weather

· Feed Intake Issues

· Standard Operating Procedures

· Stage of Production

· Herd health

1) Weather

As temperatures climb, we hear a lot about heat stress. A dairy cow experiences stress when her heat load is greater than her capacity to remove the heat. She often will adapt by modifying her metabolism to reduce heat production.

To minimize the impact of heat stress on your herd, a whole-farm approach is essential. The goal is to maintain good health, feed intake and production levels. That approach is even more critical when the Temperature-Humidity Index (THI) reaches 68 or higher.

Producers should rely on heat abatement strategies, such as the use of fans, misters and shade. Make sure these tools are well maintained and effective – this is an area that is sometimes overlooked but needs to be well established. In addition, it’s important to increase clean water supplies and avoid overcrowding as much as possible. Other points to consider:

· deliver feed during the coolest time of the day

· increase nutrient density of the ration in anticipation of lower dry matter intake

· feed high-quality forages

· increase feeding frequency to avoid heating of the ration

During heat stress, it’s also important to adopt key precision nutrients. B vitamins are essential to supporting efficient glucose and protein production, and research shows that a blend of protected B vitamins can help cows cope with heat stress. By supplementing during known stress periods, we can overcome many of the negative outcomes of strain, which in turn will help drive your farm profitability.

Don’t forget dry cows in the heat. It’s estimated that heat-stressed dry cows account for more than $800 million in milk loss annually in the United States. Conversely, taking steps to cool dry cows was shown to add to farm profits. Studies show that supplementing a blend of protected B vitamins (choline, folic acid, B12 and riboflavin) before and after calving reduced subclinical ketosis, and lowered incidence of retained placenta and metritis. Another reason to focus on dry cows is to help the calf she is carrying. Research shows that calves born from cows who experienced heat stress in late pregnancy will have lower birth weight, reduced immunity and less milk in their first lactation.

Heat isn’t the only “weather” stressor you need to worry about. Other weather-related stressors include extreme cold, humidity, excessive rain and snow, changes in daylight, and other adverse weather events. Take home message: Any weather event that impacts dry matter intake, impacts cow performance.

2) Feed Intake Issues

During the RumiNation Podcast Impacts of Stressors on Physiology and Health of Dairy Cows (Season 3, Episode 4), Dr. Trevor DeVries, University of Guelph, said cows can suffer from nutritional stress. This can be physiological, such as how her body literally reacts to a change in diet. Or it can be perceptual as the cow simply views a diet change as different and may stop eating. Or it could be behavioral due to competition for bunk space, changing a cow’s eating time and the number of meals, which in turn will negatively impact rumen health, diet absorption and digestibility. Anything that negatively impacts intake then has a trickle-down effect on energy balance, production and overall cow health.

At this year’s American Dairy Science Association’s annual meeting, two research reports were presented about DMI and nutritional stressors. Faith Reyes and her University of Wisconsin colleagues presented research related to stocking density and how more competition at the bunk lowered intake. She concluded the following: “As stocking density increased, cows appeared to modulate their bunk visits and eating rates to adjust for greater competition and less opportunity to gain feed bunk access.”

In the second report, Francesca Mazza presented a poster on feed hygiene. The report reviewed bacteria, yeasts and molds commonly found in various feed types on farms across the United States. When ingested in high amounts, these organisms can cause negative health issues, plus lead to reduced feed intake and decreased milk production. Mazza and her colleagues surveyed 8,942 feed samples collected from farms across 35 states. The results showed that spoilage organisms and potential pathogens were more prevalent in the TMR than in the individual fermented feed components of the diet. This survey highlights the importance of proper feed management practices and reducing feed contamination as a potential stressor.

Dr. Lucy concurs. He says there is no substitution for good, quality nutrition. Dr. Lucy recommends consistency. “In a perfect world, cows get the same TMR at the same time delivered by the same person using the same tractor.” He adds that this type of balance acts like a suit of armor for cows and helps them manage the strain from potential stressors.

3) Standard Operating Procedures (SOP)

Day-to-day activities can affect cows. Your daily or weekly routine procedures may seem harmless but can add up in excessive time for cows away from feed, too much time standing out of their stalls, and negative social interacts. All of which can cause issues. Having SOPs in place can help maximize efficiency and reduce stress.

Here’s a short list of potential management-related stressors:

· human-animal interactions

· stocking density

· group changes

· bunk space

· housing issues

· herd health checks

· social stress

Dr. DeVries says social stress can have a negative impact and come from a variety of places. “Cows are social animals, and they like to be in social environments,” explains Dr. DeVries, “but there are aspects of a social environment that may have a negative effect on cows and can actually be stressful. For example, overcrowding at the feed bunk or in the parlor’s holding pen.”

Dr. DeVries also mentioned the challenges of mixed-parity groups and how mixing young animals in with older animals can cause stress, especially in the younger cows.

When it comes to reducing management-related stress, attention to cow comfort is also critical. The rule of thumb: A comfortable cow is a cash cow.

Key factors to help ensure cow comfort include:

· adequate feed and resting space

· protection from the elements

· access to high-quality feed and water

· training employees on proper animal interactions

In particular regarding this last point, cows should not fear their handlers. A fearful cow is a stressed and less productive cow. Dr. DeVries said acute stressors, such as poor handling, can have a direct impact on cow physiology and her productivity. “A clear example of that is bad handling of cows in the milking

parlor,” says Dr. DeVries. “A stress like that can cause a cortisol spike in cows which may lead to a block or reduction in oxytocin release which may limit milk let down.”

There’s a new tool called farm synchronization that can help eliminate stress and maximize feed efficiency. During the RumiNation Podcast Increase Milk Production with Farm Synchronization (Season 2, Episodes 6 and 7), David Greene of Greene Ag Solutions and Barton, Kiefer and Associates Consulting Group, discussed how this approach can help improve milk production and labor management. According to Greene, farm synchronization marries the three main management centers: 1) feeding operation, 2) milking operation and 3) herd management. “The goal is to synchronize the milking schedule and the feeding schedule with the activities of the herd management team, whether it’s breeding or herd health checks. If we can get these three areas working together, we can maximize feed efficiency,” Greene says.

According to Greene, the goal is to feed cows about two hours ahead of their time in the parlor. This promotes more frequent smaller meals, which means extra intake, more efficiency and a healthier, more productive cow. If each department can communicate and work together, Greene said producers can see an increase of 2-3 pounds of milk for the same or less feed intake. “Every movement on the farm needs to be centered around maximizing the efficiency of milk production,” adds Greene.

4) Stage of Production

Having a calf can be one of the most metabolically stressful and challenging times for a cow. It’s critical to provide a quiet, clean and comfortable maternity pen, plus reduce environmental and social stresses.

In addition, Dr. Lucy explains that stress is a big factor in getting cows pregnant. “Traditionally, we always thought about the effects of stress on ovarian function. Whether or not the cow had started cycling and come into heat. But more recently, we’re trying to understand specifically how stress affects uterine function and the preparation of the uterus for that pregnancy.”

According to Dr. Lucy, it’s important for producers to understand that reproduction starts in the dry cow pen. “Avoid the long-term drag on cows and take care of them in the transition pen.”

We know that stressors can negatively impact fertility, so it’s important to direct resources toward prevention and early detection. There are tools available to help monitor how cows are reacting to stress. For example, excessive weight loss in early lactation can be monitored via body condition scoring (BCS) and by new technology such as body weight camera imaging. Why is monitoring weight loss in early lactation important? A reduction in BCS in the first 30 days in milk can lead to decreased fertility and loss of conception. Find time to monitor weight loss in early lactation and use the data to make improvements.

5) Herd Health

Exposing a cow to unnecessary stress can increase susceptibility to diseases. Manage, prevent and treat early, said University of Manitoba animal science professor Dr. Meagan King during the RumiNation Podcast Precision Technology to Monitor and Predict Animal Health (Season 3, Episode 5). From subclinical ketosis to moderate lameness and mastitis, she recommends jumping on any problem early.

Dr. King’s research has been looking at the impact of stressors on production, whether it is from lameness, overcrowding or feed delivery. She recommends using precision technology, such as rumination or activity tracking information, to look at behavior, help identify problems promptly and make better management and nutritional decisions to treat the problem.

Research also shows that supplying essential nutrients in a form that guarantees the right level is absorbed can help support a cow’s health and metabolic well-being. For example, supplementing biotin has been

proven to improve hoof health, while protected choline and B vitamins have been used to reduce clinical and subclinical ketosis.

Climate in Canada’s prairies is ideal for raising cattle.

Despite the harsh agricultural circumstances in Alberta’s prairie state, dairy cows like the dry and chilly temperature.

In Canada, there are around 1.4 million dairy cows and 9,700 herds. The majority are situated in eastern Canada, with just a few dairy producers in the prairie provinces. There are around 500 dairy producers in Alberta, the final plains province before the huge Rocky Mountains. The average size of a herd in Canada is just approximately 100 cows. However, there are herds of 400 dairy cows in Alberta.

The dairy cows seem to flourish in Alberta’s dry and frigid environment, where summer lasts just four months and the temperature difference between summer and winter ranges from 35°C to -40°C. The province’s dairy herds produce between 10,000 and 12,000 kg of milk per cow per year on average.

Holstein cows grazing in a flat grassland

We went to one of these milk producers, which had 410 Holstein cows. The property is located approximately an hour north of Calgary on the relatively flat prairie. The farm is operated by Arie and Anita Van den Broek, who are in their 60s, and their five children, Meike, Lieke, Gijs, Teun, and Geertje.

The family immigrated from the Netherlands in 2000 and purchased the property in Olds. It was formerly a cow farm where beef cattle were bred and plants were grown. Arie and his family converted the enterprise to organic milk production a few years after the acquisition, and they acquired a certificate for this in 2009. They began with a herd of 50 cows and have now expanded to 410 cows.

“The reason we left the Netherlands was the increasingly restrictive conditions for running milk production – far too many restrictive retail rules from the EU made running a farm in the Netherlands more and more difficult.” That is why, like many other Dutch milk producers, we decided to try our luck in Canada. And we haven’t looked back since coming here,” Arie explains.

The farm comprises an additional 1,000-hectare plot of land where spring barley, peas, maize, ryegrass, and lucerne for silage are farmed in a three-year crop cycle. On the farm, all plant products are utilized to feed the cow herd. A third of the feed must be organically cultivated, according to the standards.
Son Teun van den Broek tells about the dairy farm in Canada in the cow barn. Son Teun van den Broek tells about the dairy farm in Canada in the cow barn.
Cattle bedding

The straw from the barley is utilized for bedding in the stable buildings, and the cow beds in the resting barn are covered with gravel. This implies that it is usually always dry here. Fertiliser is driven out from the farm just outside the stables twice a year, and the fertiliser demand in the fields is assessed using a computer twice a year.

“We use precision agriculture on the farm in the form of digital technologies to collect and analyze data about field conditions.” This offers us an idea of how much fertilizer the crops need, allowing us to optimize fertiliser distribution in the field, which benefits both us and the environment,” adds Teun.

He goes on to say that fertilizer, seed, and plant protection are all rated. “We use the data from the previous year’s treatments and the yield maps to determine whether we distributed our fertilizer and plant protection correctly.” We must follow specific standards as an organic farm since we have a license. “We are a member of Alberta Milk, which advises us and sets the rules for our production,” Teun explains.

Milking takes done three times a day on the farm. Milking takes done in the farm’s milking carousel, which can accommodate 28 cows at a time, and it takes 4 hours to milk all of the cows. Last year, the herd produced slightly over 4.7 million litres of milk, equal to an average of just under 11,000 kg milk per cow per year.

Payment is made per litre of milk.

“At the moment, we get approximately 1 Canadian dollar (US$0.74) per litre of milk from the dairy, and when it comes to organic milk, the price is approximately 20 cents higher per litre/kg milk,” Teun says, adding that cows are typically weaned after 6-8 calvings, with the highest yielding cows able to be weaned later.

Weaner cows are sold to a local butcher for about €1,020,00 each slaughter cow. Mastitis is uncommon in the herd because to the cold winter temperature and generally dry barns. The daily cell count is roughly 170,000, with a high of 400,000. In terms of breeding, the farm works with researchers at Olds Technical University, which is just around 20 kilometers away.

In addition to the roughly 1,200 hectares dedicated to plant breeding, the farm contains around 450 hectares of pasture on which all cows and calves over the age of 8 months graze during the summer. Milking robots are used by 16% of Canada’s milk producers, while the remainder utilize milking carousels. 45% of the milk produced is consumed by humans, while the remainder is processed into over 500 different products.

Approximately 30% of dairies in the milk business are cooperatives. The dairy industry aims to have zero CO2 emissions by 2050. Teun is in charge of field management, while Geertje is in charge of milking. In addition, there are 20 personnel, 8 of them are full-time, to oversee the field and herd. Mexico accounts for half of the workforce. “The employees from Mexico are a good and stable workforce who are knowledgeable about agriculture, which is why we hired them,” Arie explains.

Farm for visitors

“We like discussing our production. People outside of agriculture, in our view, know much too little about agriculture. That’s why we formed the East Olds Dairy Farmers organization, which is made up of numerous dairy farmers,” Arie explains.

“The goal was to invite people from the local community to come to our farms and have breakfast while we talked about where the milk comes from, how we care for our animals, and how we look after our neighbors,” he continues. Our philosophy is to open the farm gate and welcome visitors. The Southern Alberta Holstein Club and Alberta Milk helped us hold the inaugural breakfast in 2013, and 348 individuals attended. Since then, we’ve refined the idea, and each year, over 1,000 people visit the six farms engaged in the initiative for breakfast.”

Investing in Feed Efficiency Can Reduce Cattle Emissions

As the world grapples with the urgent need to address climate change, the agricultural sector faces increasing scrutiny for its contribution to greenhouse gas emissions. Livestock, particularly cattle, are a significant source of methane emissions, a potent greenhouse gas that has a much greater warming potential than carbon dioxide over a shorter time frame. However, there is a promising solution that not only reduces emissions but also improves the sustainability and profitability of the cattle industry: investing in feed efficiency.

The Emissions Challenge

Cattle are responsible for a substantial share of global greenhouse gas emissions, primarily due to enteric fermentation, the digestive process that produces methane in their stomachs. This methane is then released into the atmosphere when cattle burp. According to the Food and Agriculture Organization (FAO), enteric fermentation accounts for nearly 40% of global methane emissions. To combat climate change effectively, it is crucial to find ways to reduce these emissions while still meeting the growing global demand for meat and dairy products.

Feed Efficiency as a Solution

Feed efficiency refers to the ability of cattle to convert the feed they consume into body weight. Cattle that are more feed-efficient require fewer resources to produce the same amount of meat or milk, which has several benefits:

  1. Reduced Methane Emissions: Feed-efficient cattle produce less methane per unit of meat or milk. This reduction in methane emissions directly contributes to mitigating climate change.
  2. Lower Feed Requirements: By improving feed efficiency, cattle can produce the same amount of meat or milk while consuming less feed. This not only reduces the environmental impact but also lowers production costs for farmers.
  3. Increased Profitability: Farmers can realize significant financial benefits by investing in feed efficiency. Reduced feed costs and improved production efficiency lead to higher profit margins.
  4. Sustainable Agriculture: Embracing feed efficiency aligns with the principles of sustainable agriculture, ensuring that the cattle industry remains viable in the face of environmental challenges.

Investment Opportunities

Investing in feed efficiency involves several strategies and technologies:

  1. Genetic Selection: Breeding programs can be used to select for cattle with superior feed efficiency traits. Over time, this can lead to herds that are more environmentally friendly and economically efficient.
  2. Nutritional Management: Optimizing the diet of cattle to improve their digestive efficiency can significantly reduce methane emissions.
  3. Monitoring and Data Analytics: Implementing technology to track cattle performance and feed efficiency can help farmers make data-driven decisions to enhance their operations.
  4. Methane Reduction Technologies: Researchers are developing innovative solutions, such as feed additives and dietary supplements, that can reduce methane emissions from cattle.

Conclusion

Investing in feed efficiency is a win-win solution for the cattle industry and the environment. By reducing methane emissions from cattle, it contributes to global efforts to combat climate change while simultaneously improving the profitability and sustainability of the livestock sector. Governments, agricultural organizations, and farmers should collaborate to promote and adopt feed efficiency strategies, ensuring a more sustainable and environmentally responsible future for cattle production. This investment is not just in the cattle industry; it’s an investment in the health of our planet.

When milk prices are down, where can you make sacrifices?

The dairy industry is no stranger to price fluctuations, and when milk prices take a nosedive, dairy farmers and producers are faced with tough decisions. In such challenging times, it becomes crucial to identify areas where sacrifices can be made to weather the storm without compromising the overall quality and sustainability of the operation. This article explores some strategies and considerations for navigating low milk prices in the dairy industry.

  1. Cost Management

    One of the first areas to scrutinize when milk prices are down is your cost structure. Analyze your expenses meticulously and identify areas where cost-saving measures can be implemented without affecting the health and well-being of your herd or the quality of your dairy products. Some potential cost-saving strategies include:

    • Feed Efficiency: Review your feed program and explore ways to improve feed efficiency. This might involve adjusting the composition of the feed, sourcing more cost-effective ingredients, or optimizing feeding practices.
    • Labor Costs: Evaluate your labor costs and consider options such as cross-training employees to handle multiple tasks or adjusting work schedules to maximize efficiency.
    • Energy and Utilities: Look for ways to reduce energy consumption on the farm, whether through better insulation, energy-efficient equipment, or alternative energy sources like solar power.
  2. Herd Management

    Your cows are the heart of your dairy operation, and their health and productivity are paramount. While you may need to make some adjustments during tough times, ensure that you maintain high standards of care and management. Consider the following:

    • Healthcare: Continue to invest in the health and well-being of your herd. Cutting corners on healthcare can lead to long-term issues and decreased milk production.
    • Breeding and Genetics: Evaluate your breeding program to ensure you are producing cows that are well-suited to your operation. High-quality genetics can pay dividends in terms of milk production and longevity.
  3. Product Diversification

    When milk prices are low, consider diversifying your product offerings. Explore options such as producing artisan cheeses, yogurt, or other dairy products that can fetch higher prices in the market. While this may require additional equipment and marketing efforts, it can provide a valuable income stream.

  4. Market Analysis and Contracts

    Stay informed about market trends and pricing. Consider entering into contracts or agreements with processors or cooperatives that provide price stability or incentives during periods of low milk prices.

  5. Financial Planning

    Maintaining a robust financial plan is crucial during volatile periods. Build up cash reserves during times of prosperity to help cushion the impact of low milk prices. Additionally, consider working with financial advisors who specialize in the agricultural sector to navigate challenging financial situations.

  6. Sustainable Practices

    Embrace sustainability practices that can reduce operating costs and improve your farm’s resilience in the long run. Implementing eco-friendly measures like nutrient management plans and waste reduction can lead to cost savings and a more environmentally responsible operation.

When milk prices are down, dairy farmers face tough choices, but it’s essential to approach these challenges strategically. By carefully managing costs, prioritizing the health and well-being of your herd, diversifying products, staying informed about market trends, and maintaining financial resilience, you can navigate periods of low milk prices while positioning your dairy operation for long-term success. Adaptability and a commitment to sustainable practices will be key to enduring the cyclical nature of the dairy industry.

Dairy producers are “caught in the crossfire” as financial demands mount.

The Royal Association of British Dairy Farmers (RABDF) has warned that the difference between farmgate milk and retail pricing will continue to widen, and that high input costs would put major burden on the industry.

According to government data, the average UK gate price for milk in June was 36.48 pence per litre (ppl), a 16% decrease from the previous month. Meanwhile, the present cost of production is expected to be between 40ppl and 45ppl, rendering many dairy farms unsustainable.

According to RABDF chairman Di Wastenage, producers are caught in the crossfire, with no respite expected in the short to medium term.

“Our dairy farmers are facing enormous financial pressures,” she said. “They are caught in the crossfire, with farm gate milk prices remaining low while farm input costs remain stubbornly high, and high retail prices also have an impact on consumer demand.”

Mrs. Wastenage went on to say that UK processors are also dealing with increased energy and labor expenses, which are reflected in the pricing. Furthermore, she noted that the increased retail price of some dairy goods, such as cheese, is due to producers employing higher-cost milk earlier this year.

In terms of the next six months, she believes global markets provide little hope for UK dairy producers.

“The decline in Chinese demand for whole milk powder (WMP) and Fonterra’s forward forecasting indicate that this is going to be a difficult year.” “Unfortunately, for many people, this may be financially unsustainable,” she cautioned.

“The UK requires a dairy industry that operates efficiently and profitably from the farmgate to the supermarket shelf for all sectors along the supply chain.” Mrs Wastenage said, “We must ensure that this occurs and that the value is shared by all parties.”

3 big benefits of cow locating

Finding an individual cow or even a few cows in larger groups that need to be checked, inseminated, treated or fetched isn’t exactly like finding a needle in a haystack. But sometimes it feels that way.

Cow location technology can help reduce frustration, stress and lost time spent seeking specific animals.

Think of this technology like the “Find My Phone” app for your smartphone. It automatically locates the cows you need and accurately pinpoints their real-time position on your barn map with one click – making your team infinitely more efficient. And it positively affects milk production and cow time budgets.

Here are three reasons to stop searching and start finding the cows you need.

  1. You can focus on areas with the most need
    “One of the biggest benefits of cow location technology is that you don’t need to install it all at once,” notes Ron Dehli, Nedap technical business development manager. “You can start with a tag that accepts location and the hardware can be added later. You can begin with one location or pen and add to your system over time.”
    Facility layout and management styles play important roles in determining how cow locating fits into your dairy, but the highest priority areas should always be the cows requiring the most management.
    “The technology fits most modern dairy facilities as long as you include infrastructure to mount a beacon, such as a barn or a fully supported sunshade,” adds Dehli.
    Transition pens, breeding pens and similar areas where cows require more attention are good places to initially install location system components. Pens for mid- to late-lactation cows can be added later if not included in the introductory installation.
  2. Your team can effectively focus on needed tasks
    The ability to find specific animals quickly and accurately means your team can be more efficient with time. Instead of searching pens for an animal, they can spend their efforts on more mindful tasks like breeding and animal care. This holds true in conventional and robotic dairy facilities.
    “Cow locating technology frees up labor to do different jobs on the farm, jobs that sometimes are a higher priority than hunting down the few animals you’re trying to find,” says Tara Bohnert, Nedap business development manager. “We’ve seen dairies be able to pivot and reallocate where their labor spends time.”
    Depending on how the technology is used, cow locating has been able to free up the equivalent of a full-time person to do other tasks on the farm.
    Of course, before investing in any technology seek employee buy-in and develop a plan for implementation so employees can feel it’s a part of their success and not a threat to their role or position on the farm.
  3. You can reduce interruptions to cow routines
    Your team isn’t the only part of your farm affected by more targeted herd interactions. Cows benefit too.
    “Less disruption to daily activities is an important outcome of more efficient cow locating,” says Dehli. “The fewer interactions you have with cows throughout their day, the better. Let her do what she likes to do – eat, drink and lie down. If we can easily and remotely find a cow, we don’t have to disrupt an entire pen looking for one out of 200 herd mates. It’s critical to minimize human-cow interactions and let cows be cows.”
    While it’s difficult to assign a specific price tag to reduced herd interactions, anecdotally, dairies report increased milk production of 1-2 pounds per cow per day thanks to less time away from feed and water for the whole group, not just those that require attention.
    “It’s not just about those cows we need to find; it’s about all those other cows whose day we’ve influenced,” Bohnert says. “Pounds of milk are easy to pencil out when evaluating the return on investment for a system. The cost of a pound per cow on the size of herds we’re talking about adds up quickly.”
    Additionally, for larger dairies, especially those that have pens with 500 or 600 cows, cow locating can also help with identifying animals in the wrong pen.
    “When it’s time to seek animals, we’re not circling through a pen that a specific cow may not even be in. Location becomes a great tool for dairies to manage where their animals are,” notes Bohnert.
    “The success of cow locating comes down to the data points you’re monitoring, your farm’s progressiveness, your labor force and how you want people to interact with your herd,” concludes Dehli.

Enzymes to Improve Rumen Fermentation in Dairy Cows: A Step Towards Greater Efficiency and Long-Term Success

Dairy production is crucial to supplying worldwide demand for milk and dairy products. The effectiveness of milk production in dairy cows, on the other hand, is mostly determined by their digestive system, notably the rumen. The rumen is a sophisticated microbial fermentation chamber that converts feed into nutrients. Researchers and farmers are investigating the use of enzymes to improve rumen fermentation in order to improve dairy cow performance. This article examines the possible advantages and drawbacks of using enzymes in dairy cow diets.

The Importance of the Rumen

The rumen is the first and biggest compartment in a dairy cow’s stomach, and it is home to a varied array of microorganisms such as bacteria, fungus, and protozoa. These bacteria collaborate to break down fibrous plant material into volatile fatty acids (VFAs), which are ingested by the cow and provide energy for milk production.

Rumen Fermentation Enzymes

Enzymes are biological molecules that help to speed up chemical processes. In the case of dairy cows, enzymes may be given to their meals to improve the digestion of complex carbohydrates, proteins, and lipids, eventually enhancing milk output and cow health. Among the main enzymes found in dairy cow diets are:

  1. Cellulase and hemicellulase enzymes degrade plant fibers, making it simpler for rumen bacteria to digest cellulose and hemicellulose. This optimizes fiber use and boosts VFA generation.
  2. Proteolytic enzymes help to break down food proteins into smaller peptides and amino acids. This increases rumen microbial protein synthesis, resulting in higher milk protein output.
  3. Lipase Enzymes: Lipases are enzymes that convert dietary lipids to fatty acids, which are then digested in the rumen. This method has the potential to increase the energy content of the diet.

The Advantages of Enzyme Supplementation

  1. Improved Nutrient Utilization: Enzymes assist dairy cows in extracting more nutrients from their meal, enhancing feed conversion efficiency.
    Improved Milk Production: Enzymes may increase milk output and composition, including increased fat and protein content, by boosting rumen fermentation.
  2. Reduced Environmental Impact: Improved rumen fermentation may result in lower methane emissions, which helps the dairy sector meet its sustainability objectives.
  3. Cows that are healthier: Nutritional enhancements such as enzyme supplementation may result in healthier, more productive dairy cows.

Considerations and Obstacles

While using enzymes in dairy cow diets has various advantages, there are certain drawbacks to consider:

  1. Cost: Enzymes may be costly, thus a positive cost-benefit analysis is required for farmers to use this technology.
  2. Feed Formulation: Because the efficiency of enzymes varies depending on food composition and environmental circumstances, proper feed formulation is required.
  3. Regulatory Considerations: In many countries, the use of enzymes in animal feed is subject to regulatory permission and control.
  4. Microbial Adaptation: Over time, rumen microorganisms may adapt to enzyme supplementation, diminishing its efficiency.

Conclusion

Enzyme supplementation in dairy cow diets has the potential to revolutionize milk production by boosting milk output, improving nutrient use, and lowering environmental consequences. However, using this technology should be addressed with a thorough awareness of its merits and drawbacks. Enzymes provide a possible option for improving rumen fermentation and, eventually, dairy cow productivity as the dairy industry pursues sustainable and effective means of production. More study and practical application are required to fully realize the potential of enzymes in dairy production.

Regenerative Dairy Farming: Sustaining the Land and the Herd

Dairy farming has long been a cornerstone of agriculture, supplying people all over the globe with milk, cheese, and other dairy products. Traditional dairy farming techniques, on the other hand, have often been linked to environmental damage, such as soil erosion, water pollution, and greenhouse gas emissions. In response to these issues, a rising movement called as regenerative dairy farming is gaining traction. This strategy intends to not only preserve dairy production but also to repair and improve land health, increase animal welfare, and minimize the industry’s environmental imprint.

What precisely is Regenerative Dairy Farming?

Regenerative dairy farming is a comprehensive and long-term strategy to dairy production that aims to emulate natural ecosystems and processes in order to build a more resilient and ecologically friendly agricultural system. It lays a heavy focus on soil health, biodiversity, and herd health. Here are some significant regenerative dairy farming philosophies and practices:

  1. Improving Soil Health: Regenerative farming is built on healthy soil. Farmers emphasize the development and maintenance of nutrient-rich soil via methods like as cover cropping, decreased tillage, and the use of organic matter such as compost. Not only does healthy soil promote higher agricultural development, but it also sequesters carbon, lowering greenhouse gas emissions.
  2. Biodiversity is prioritized on regenerative dairy farms via the planting of varied cover crops, the establishment of hedgerows, and the creation of wildlife habitat. This promotes ecological equilibrium, enhances pollination, and decreases the need for chemical inputs.
  3. Rotational grazing: Rather than confining cows to a single area, regenerative dairy farms use rotational grazing systems. This gives the land a chance to rest and renew, avoiding overgrazing and soil damage. It also promotes the development of a varied range of forage plants.
  4. Reduced Chemical Inputs: These farms employ natural and organic fertilizers and insecticides instead of synthetic fertilizers and pesticides. This decreases chemical discharge into streams while also encouraging healthier ecosystems.
  5. Animal Welfare: The well-being of the herd is prioritized in regenerative dairy production. Cows are usually given greater space to graze, wander, and show natural behaviors. This results in happier cows as well as higher-quality milk.

The Advantages of Regenerative Dairy Farming

  1. Environmental Sustainability: Regenerative approaches lessen dairy farming’s environmental effect. They aid in the sequestration of carbon, the reduction of greenhouse gas emissions, and the protection of water quality by minimizing fertilizer runoff.
  2. Economic Resilience: Regenerative dairy farming may improve a farm’s economic resilience by increasing soil quality and minimizing the demand for expensive inputs. It also provides the opportunity for several revenue streams via sustainable practices.
  3. Higher-Quality Dairy Products: Cows that are healthier and happy generate higher-quality milk and dairy products. This might lead to greater market demand and higher farm prices.
  4. Climate Change Resilience: Regenerative agricultural systems are often more robust to severe weather events, making them well-suited to the difficulties presented by climate change.

Adoption and Obstacles

While regenerative dairy farming has immense potential, it is not without difficulties. Transitioning away from traditional techniques may be expensive and time-consuming. Farmers will require knowledge, training, and financial assistance to make the transition. Furthermore, regenerative approaches may need additional management and labor, which may not be possible for many farms.

Despite these obstacles, regenerative dairy farming is becoming more popular. This shift is being driven by consumers’ increased desire for sustainable and ethically produced dairy products, as well as acknowledgment of the environmental advantages. Many farmers are learning that the long-term advantages of regenerative farming approaches outweigh the early challenges.

Conclusion

Regenerative dairy farming indicates a favorable trend in the dairy sector toward more ecologically friendly and sustainable approaches. This strategy tries to balance the requirements of humans, the land, and the herd by emphasizing soil health, biodiversity, animal welfare, and decreased chemical inputs. The dairy sector has the potential to become a pioneer in sustainable agriculture as more farmers embrace regenerative techniques, contributing to a healthier world and higher-quality dairy products for customers.

Optimizing Ventilation in Dairy Calf Barns for Healthy Growth and Welfare

Proper ventilation is a critical aspect of managing dairy calf barns to ensure the health, comfort, and growth of young calves. Adequate ventilation helps regulate temperature, humidity, and air quality, creating an environment that minimizes the risk of respiratory illnesses and supports overall calf well-being. In this article, we will discuss the importance of calf barn ventilation and key strategies for achieving optimal air exchange.

Why Ventilation Matters: Dairy calves are particularly sensitive to changes in temperature and air quality. Poor ventilation can lead to the accumulation of airborne pathogens, humidity, and ammonia, all of which contribute to respiratory issues, decreased feed intake, and compromised growth. Proper ventilation addresses these challenges by maintaining a comfortable and clean environment.

Ventilation Strategies:

  1. Natural Ventilation: Natural ventilation relies on the design of the barn to facilitate the movement of air through openings such as windows, doors, and roof vents. Cross-ventilation design ensures a continuous exchange of fresh air and removal of stale air.
  2. Mechanical Ventilation: Mechanical systems, such as fans and exhaust systems, can provide controlled air exchange regardless of external weather conditions. These systems can be crucial in regions with extreme weather variations.
  3. Curtain-Sided Barns: This design combines natural ventilation with the use of adjustable curtains along the sides of the barn. Curtains can be raised or lowered to regulate airflow and temperature based on calf needs and weather conditions.

Considerations for Effective Ventilation:

  1. Airflow Rate: The appropriate airflow rate depends on factors like calf density, barn size, and environmental conditions. Adequate ventilation ensures that the air is replaced frequently, reducing the concentration of moisture and pathogens.
  2. Humidity Control: Proper ventilation helps maintain optimal humidity levels. High humidity can lead to moisture buildup, which in turn increases the risk of respiratory issues and bacterial growth.
  3. Air Quality: Effective ventilation helps remove ammonia and other pollutants that can accumulate in calf barns. This contributes to better respiratory health and overall calf comfort.
  4. Temperature Regulation: Ventilation plays a role in temperature control by preventing heat buildup in the barn during hot weather and providing ventilation during colder periods to reduce humidity and moisture.

Management and Maintenance:

  1. Regular Monitoring: Monitoring barn conditions, including temperature, humidity, and air quality, is essential. Invest in monitoring systems that provide real-time data for informed decision-making.
  2. Cleaning and Sanitization: Regularly clean and sanitize barn surfaces to prevent the buildup of pathogens that can negatively impact air quality and calf health.
  3. Proper Placement: Ensure that fans, vents, and openings are strategically placed to provide uniform airflow throughout the barn, minimizing areas of stagnant air.

Ventilation is a fundamental component of successful dairy calf management. Implementing effective ventilation strategies ensures that calves are raised in an environment that promotes respiratory health, optimal growth, and overall well-being. Dairy farmers should assess their barn layout, environmental conditions, and calf needs to determine the best ventilation approach, whether it’s through natural ventilation, mechanical systems, or a combination of both. Regular monitoring and maintenance are key to creating a calf-friendly environment that sets the stage for healthy and productive adult cows.

Protecting Your Dairy Herd from Pinkeye: Strategies and Prevention

Pinkeye, scientifically known as bovine infectious keratoconjunctivitis, is a contagious and economically detrimental eye infection that commonly affects dairy cattle. The condition is characterized by inflammation of the eye’s cornea and conjunctiva, leading to discomfort, reduced milk production, and potential long-term damage if left untreated. Implementing effective strategies for prevention and management is essential to safeguard your dairy herd’s health and productivity.

Causes and Transmission: Pinkeye is primarily caused by the bacterium Moraxella bovis. Flies, particularly face flies and house flies, play a significant role in transmitting the infection by transferring bacteria from infected to healthy animals. Factors such as UV radiation, dust, and poor nutrition can weaken the eye’s defenses, increasing the susceptibility of cattle to pinkeye.

Preventive Measures:

  1. Fly Control: Implement rigorous fly control measures to reduce the presence of disease-carrying flies. This includes using insecticides, physical barriers, and environmental modifications to minimize fly populations around the cattle.
  2. Pasture Management: Maintain clean and dry pastures to minimize dust and mud, which can irritate the eyes and provide a conducive environment for bacterial growth.
  3. Proper Nutrition: Ensure that your cattle receive a balanced diet rich in vitamins and minerals essential for immune system support. A strong immune system can better resist pinkeye infections.
  4. Shade and UV Protection: Provide adequate shade to protect the eyes from direct sunlight and UV radiation. UV exposure can contribute to eye irritation and increase the susceptibility to pinkeye.
  5. Quarantine and Biosecurity: Isolate new animals before introducing them to the herd to prevent the introduction of pinkeye and other diseases. Implement strict biosecurity measures to minimize the risk of disease spread within the herd.

Management Strategies:

  1. Early Detection: Train personnel to recognize the early signs of pinkeye, such as excessive tearing, blinking, and redness of the eye. Early detection allows for prompt treatment and prevents further spread.
  2. Isolation and Treatment: Infected animals should be isolated to prevent the spread of the infection. Consult a veterinarian for appropriate treatment options, which may include topical antibiotics and anti-inflammatory medications.
  3. Eye Protection: Consider using fly masks or face shields to protect susceptible cattle from flies and environmental irritants that can exacerbate pinkeye.

Herd Health Monitoring:

  1. Regular Checkups: Schedule regular veterinary visits to assess the overall health of the herd and identify potential cases of pinkeye early.
  2. Eye Scoring: Implement an eye scoring system to objectively evaluate the eye health of each animal. This helps track the prevalence of pinkeye within the herd and the effectiveness of prevention strategies.

Pinkeye poses a significant threat to dairy herd health and productivity. By implementing a combination of preventive measures, early detection, proper management, and consistent monitoring, dairy farmers can effectively protect their herds from pinkeye and its negative consequences. An integrated approach involving fly control, good nutrition, and veterinary care is key to ensuring the well-being of your cattle and the success of your dairy operation.

Managing Digital Dermatitis in Dairy Cows

Digital dermatitis (DD), commonly known as “hairy heel warts,” is a prevalent and economically significant hoof disease affecting dairy cattle worldwide. It is characterized by painful lesions on the skin of the digital region, primarily the rear hooves, leading to lameness and decreased milk production. Effective management strategies are crucial to minimize the impact of digital dermatitis on animal welfare and farm profitability.

Causes and Risk Factors: DD is caused by a synergistic infection of Treponema bacteria, particularly Treponema medium and Treponema vincentii. Several risk factors contribute to the development of DD, including poor hygiene, moist environments, inadequate hoof trimming, and high stocking densities. The bacteria thrive in damp and dirty conditions, making proper housing and hygiene practices critical for prevention.

Preventive Measures:

  1. Clean and Dry Environment: Regular cleaning of cow housing and dry resting areas is essential. Adequate drainage and proper ventilation can help reduce moisture levels, which inhibit bacterial growth.
  2. Hoof Trimming: Routine hoof trimming maintains proper hoof health and prevents overgrowth, reducing the risk of lesion formation. Trimming also helps identify and address early signs of DD.
  3. Footbaths: Footbaths containing various disinfectants, such as copper sulfate, formalin, or organic acids, can be effective in preventing and controlling DD. Regular footbathing schedules should be followed, and footbath solutions should be rotated to prevent bacterial resistance.
  4. Proper Nutrition: A balanced diet rich in essential nutrients supports overall cow health, including hoof health. Consult a veterinarian or nutritionist to ensure cows receive the necessary nutrients.
  5. Biosecurity Measures: Restricting the movement of infected animals and implementing biosecurity protocols for visitors and equipment can prevent the introduction and spread of DD within the herd.

Treatment Strategies:

  1. Individual Treatment: Early identification and treatment of lesions are crucial. Lesions should be cleaned, disinfected, and covered with appropriate bandages. Consult a veterinarian for guidance on suitable topical treatments.
  2. Systemic Antibiotics: In severe cases, a veterinarian may prescribe systemic antibiotics to control bacterial infection. However, this should be a last resort due to concerns about antibiotic resistance.

Herd Monitoring and Management:

  1. Regular Inspection: Routine hoof inspections are necessary to detect lesions early. Dedicated personnel should be trained to identify and treat DD.
  2. Record Keeping: Maintaining accurate records of DD cases, treatment protocols, and outcomes helps track the effectiveness of management strategies.
  3. Lameness Scoring: Implementing a lameness scoring system allows for the objective assessment of cow mobility and the management program’s effectiveness.

Digital dermatitis can significantly impact dairy cow welfare and farm economics. Implementing a comprehensive approach involving preventive measures, early treatment, and regular monitoring is essential for effectively managing DD. Collaboration between dairy managers, veterinarians, and other professionals is key to developing and maintaining successful DD management strategies.

Momentum for block calving continues for GB farmers

According to 2022 BCMS data, the share of GB farms running any type of block calving system has risen to 18.7%, while the number of farms running an all year round (AYR)* system has eased back from 2021 figures to 30.7%. If we look over a longer time period, there has been a significant trend towards farmers adopting a specific calving system. In 2016 58.5% of farms were categorised as non-defined* in their calving pattern, in 2022 this has fallen to 50.6%.

bar chart showing changes in the number of farmers following calving systems over time

With AYR calving remaining fairly steady around the 30% mark, the biggest shift has been those choosing to adopt a block calving system which has risen by 6.6 percentage points since 2016. Within this, Autumn* block calving has been the most favourable moving up 2.6 percentage points from 2016 to 5.4% of total farm numbers in 2022. The numbers of farms choosing to follow Spring block* and dual block* have moved up to 5.3% and 4.2% respectively. This movement has exaggerated the peaks and troughs in the seasonal birthing profile of the GB dairy herd.

line graph showing the monthly numbers of calf registrations from dairy coes

As a general rule, the larger farms, in terms of number of births per year, operate a more defined system. The number of larger farms has been increasing over recent years, with the largest farms (those with over 500 births per year) favouring an all year round (AYR) calving pattern (63.3%) and less than 10% falling into the non-defined category. Farms with between 200-500 births per year, see a more mixed approach to operating systems with 46.3% AYR, 10.1% Autumn block, 10.0% Spring block, however they do see a larger number in the non-defined group (25.9%). The smallest farms (those with less than 200 births per year) have been in decline in recent years, the majority (62.0%) of farms this size sit as non-defined with just over a quarter following an AYR system and the remainder (12.5%) in a block calving operation.

*Definitions for analysis

2020 was the first time we were able to see the breakdown based on calf registrations for each farm in the country. Historically, the breakdown of system in GB has been based on farmers’ self-assessment of which system they believe they operate.

The data excludes any farms where all registrations were for non-dairy calves, and also excludes farms who had less than 25 calf registrations in the year.

Our farm key performance indicators suggest block calving herds should target 85% of calvings within a 6-week window, although the “good” level is set at between 70-85%. For this analysis we have used a wider definition of 4 months and 80% of registrations as set out below:

  • Spring block: 80% of registrations occur within 4 months from 1 Feb to 31 May
  • Autumn block: 80% of registrations occur within 4 months from 1 Aug to 30 Nov or 1 Sep to 31 Dec
  • Other block: 80% of registrations occur within 4 months other than defined in spring or autumn block
  • Dual block: 90% of registrations occur within the spring block or autumn block windows defined above.
  • AYR: Registrations are spread relatively evenly throughout the year, but that can be based on a 12-month, 11-month or 10-month calving system. 12-month means each month sees 3.3%-13.3% of annual registrations. 11-month means 4.1%-14.1% of annual registrations in 11 months of the year, and 10-month means 5%-15% of annual registrations in 10 months of the year.
  • Non-defined: covers any farm not falling into one of the other categories.

5 Steps to Minimize Feed Refusals in Dairy Cattle

Feed refusals in dairy cattle can lead to reduced milk production, compromised animal health, and increased costs for farmers. Minimizing feed refusals is crucial for optimizing the productivity and profitability of dairy operations. In this article, we will explore five effective strategies that can help dairy farmers manage and minimize feed refusals, ensuring healthier and more productive dairy cattle

Step 1: Balanced Ration Formulation

Balanced ration formulation is a critical aspect of livestock management, ensuring that animals receive the necessary nutrients for optimal health and productivity. However, even with a perfectly balanced diet, feed refusal can still occur, leading to wastage and potential negative impacts on animal performance. In this article, we will explore practical strategies on how to minimize feed refusal through effective balanced ration formulation.

  1. Understand the Nutritional Requirements:
    To create a truly balanced ration, it’s essential to understand the specific nutritional requirements of the target livestock. Factors such as age, weight, breed, production stage (e.g., growth, lactation, or maintenance), and environmental conditions must be taken into account. Collaborate with a qualified animal nutritionist or use reputable software to calculate the exact nutrient needs and develop a precise ration plan.
  2. Utilize High-Quality Ingredients:
    Selecting high-quality ingredients is paramount to minimize feed refusal. Opt for fresh, clean, and uncontaminated feedstuffs that are free from mold, dust, and mycotoxins. Poor-quality ingredients not only decrease palatability but may also compromise animal health. Consistently assess the nutritional value of your feedstuffs and consider sourcing from reputable suppliers.
  3. Optimize Particle Size:
    The particle size of feed plays a crucial role in promoting feed acceptance. For ruminants like cattle, ensuring that the ration has an appropriate particle size distribution is essential for efficient rumination and digestion. Fine particles can lead to sorting and reduce effective fiber intake, while overly coarse particles can discourage feeding. Aim for an optimal particle size range to enhance palatability and prevent feed sorting.
  4. Monitor Forage Quality:
    Forage constitutes a significant portion of the diet for many livestock species. Ensuring high-quality forage is available is vital to minimize feed refusal. Regularly assess the nutritional value of forages through laboratory analysis to adjust the ration accordingly. Properly stored and well-preserved forages are more likely to be accepted by animals, contributing to increased feed efficiency.
  5. Consider Feed Additives:
    Incorporating feed additives can enhance the palatability of the ration and reduce feed refusal. Substances such as flavors, yeast-based products, and certain natural extracts can entice animals to consume the feed more readily. Moreover, feed additives like probiotics and enzymes can improve digestion and nutrient absorption, maximizing the benefits of the balanced ration.
  6. Implement Gradual Diet Changes:
    When introducing a new ration or making adjustments to the existing one, gradual transitions are key to reducing feed refusal. Abrupt diet changes can cause digestive upsets and lead to decreased feed intake. Over a period of days, slowly introduce the new ration to allow animals to adapt and avoid any potential stress associated with sudden dietary shifts.

Balanced ration formulation is fundamental to the success of livestock management, but it’s equally important to address feed refusal to ensure that the benefits of a well-formulated diet are fully realized. By understanding the nutritional requirements, utilizing high-quality ingredients, optimizing particle size, monitoring forage quality, considering feed additives, and implementing gradual diet changes, farmers can minimize feed refusal and optimize animal health and productivity. Regularly evaluate feed consumption and adjust the ration as needed to meet the ever-changing needs of the livestock and maximize performance for a thriving and profitable operation.

Step 2: Optimize Feed Presentation:

Optimizing feed presentation is a crucial aspect of dairy cattle management that directly impacts their feed intake and overall productivity. Feed refusals can result in reduced milk production, compromised health, and increased costs for dairy farmers. In this article, we will explore effective strategies to enhance feed presentation and minimize feed refusals in dairy cattle.

  1. Consistent Fresh Feed Delivery:
    Dairy cattle are more likely to consume feed that is fresh and palatable. Develop a regular feeding schedule to deliver fresh feed at the same times each day. This consistency helps regulate the cows’ feeding behavior and encourages them to eat when the feed is offered. Avoid leaving feed in the bunk for extended periods, as stale or spoiled feed is less appealing and may lead to refusals.
  2. Monitor Feed Trough Design:
    The design of the feed trough can significantly influence feed intake and minimize refusals. Ensure that the trough is suitable for the size and age of the cows. A shallow, wide trough is preferable, as it allows easy access to feed for all cows. Additionally, consider using rubber mats or comfortable flooring around the feed trough to encourage cows to eat without discomfort.
  3. Prevent Feed Contamination:
    Contaminated feed is unappetizing to dairy cattle and can lead to feed refusal. Keep the feed storage area clean and free from mold, pests, and debris. Use proper storage methods to protect feed from spoilage and contamination. Regularly inspect the feed for any signs of mold, discoloration, or foul odors, and remove any compromised feed to prevent negative effects on feed intake.

Optimizing feed presentation is a crucial factor in minimizing feed refusals and improving overall dairy cattle performance. By consistently delivering fresh and palatable feed, ensuring a properly mixed TMR, managing bunk space and order, monitoring feed trough design, preventing feed contamination, and implementing effective feed bunk management, dairy farmers can create an environment that encourages optimal feed intake. Reducing feed refusals not only benefits the health and productivity of dairy cattle but also leads to increased milk production and enhanced profitability for the dairy operation. Regular evaluation and fine-tuning of feed presentation practices will help dairy farmers achieve their production goals and ensure the well-being of their herd.

Step 3: Manage Feed Bunk Space and Order:

Managing feed bunk space and order is a critical aspect of dairy cattle management that directly impacts their feeding behavior and overall productivity. When feed bunk space is inadequate or the feeding order is mismanaged, it can lead to competition and stress among cows, resulting in feed refusals and decreased feed intake. In this article, we will explore effective strategies to optimize feed bunk space and order, thus minimizing feed refusals in dairy cattle.

  1. Evaluate Feed Bunk Space Requirements:
    The first step in managing feed bunk space is to assess the needs of the dairy herd. Consider the size, age, and number of cows in the group to determine the ideal amount of bunk space required. As a general guideline, provide at least 24 inches (60 cm) of bunk space per cow to allow them to access feed comfortably without being pushed out or interrupted during feeding.
  2. Divide the Herd into Smaller Groups:
    If the dairy herd is too large to ensure adequate bunk space for all cows, consider dividing the group into smaller, manageable subgroups. Smaller groups promote a more relaxed feeding environment, reducing competition and stress during feeding times. This division can be based on lactation stage, age, or production levels, ensuring that each cow has sufficient access to feed.
  3. Provide Equal Access to Feed:
    Ensuring equal access to feed is essential to avoid dominance-related refusals. Arrange feed bunks in a way that allows all cows to reach the feed simultaneously. Avoid long, narrow feed bunks where only a few dominant cows can access the feed, leaving others at a disadvantage. Use multiple feed bunks if needed to ensure all cows have fair and equal access to the ration.
  4. Observe Feeding Behavior:
    Regularly monitor cow behavior during feeding times to identify potential issues related to bunk space and order. Watch for signs of aggressive behavior, bullying, or dominant cows preventing others from eating. Address any problematic behaviors promptly, such as separating aggressive cows or providing additional feed troughs to accommodate all cows.
  5. Consider Feed Delivery Methods:
    The method of feed delivery can also influence feed bunk space and order. For instance, utilizing a total mixed ration (TMR) can help distribute nutrients more evenly, reducing the likelihood of selective feeding and refusals. Additionally, consider using a feed push-up system or automated feeders to ensure fresh feed is always available and prevent cows from waiting impatiently for feed, which may cause unnecessary stress.
  6. Create a Calm Feeding Environment:
    A calm and stress-free feeding environment encourages cows to eat without hesitation. Minimize loud noises, sudden movements, and other distractions around the feed bunk area. Dairy cattle are sensitive animals, and any disturbances can deter them from eating. A serene feeding environment positively influences feed intake and minimizes feed refusals.

Managing feed bunk space and order is crucial for minimizing feed refusals in dairy cattle. By providing adequate bunk space, dividing the herd into smaller groups, ensuring equal access to feed, observing feeding behavior, considering feed delivery methods, and creating a calm feeding environment, dairy farmers can optimize the feeding process and improve overall feed intake. Reduced feed refusals not only enhance cow health and productivity but also contribute to increased milk production and improved profitability for the dairy operation. Regularly assessing and fine-tuning feed bunk space and order management practices will help dairy farmers achieve their production goals and maintain a content and thriving herd.

Step 4: Regularly Clean Feed Bunks and Water Troughs:

Dirty or moldy feed bunks can deter cows from eating, leading to increased feed refusals. Regularly clean and disinfect feed troughs to maintain a hygienic feeding environment. Similarly, ensure that water troughs are regularly cleaned and filled with fresh water. Proper hydration is essential for feed intake, and cows are more likely to refuse feed if water availability is inadequate or of poor quality.

Step 5: Monitor Cow Health and Comfort:

The health and comfort of dairy cattle play a crucial role in their overall well-being and productivity. When cows are experiencing discomfort or health issues, it can lead to reduced appetite and feed refusals, negatively impacting milk production and overall herd performance.

Dairy farmers in Waikato are facing a feed shortage – with consistent rain destroying pastures.

A sharemilker in Te Poi and Waikato Federated Farmers dairy chair Matthew Zonderop said the region had not really had a decent dry spell since October.

“We’ve had strong gusts of wind which have been driving the rain, it’s very wet, the water table is extremely high and grasses are turning yellow from being saturated, so it’s pretty grim.

“There’s going to be a feed shortage. We’re using a lot of our spring supplement now to feed the cows because we can’t feed them enough grass because the growth rates are very low, so yeah we don’t have enough feed.”

Zonderop said any grass that was around was quickly trampled into the ground by the cows because the soil was so sodden.

“Because of all the rain the water table is really high, so it doesn’t take much for my paddocks to flood.

“Farmers are well versed at winters in Waikato so they can cope but we’re getting to the point where we are not coping.”

Farmers were taking more drastic measures like standing cows off on yards overnight, he said.

“It’s hard on the farmers’ mental well-being as well at the moment because we just don’t know where to go. We don’t know which way to turn anymore because our options are running out, it’s quite stressful.”

Bart van de Ven, a sharemilker in Springdale near Morrinsville, said the soil on his farm was so water-logged only 5mm of rain causes flooding.

The wet weather was causing big problems on his farm, he said.

“We had a pasture cover of 2600 around the 15th of May and we now have a pasture cover of 2100 which is kind of unusual because normally during the winter time you have dry cows and you go on a longer round and build up grass for calving but we’ve actually gone down which is the main worry for us.

“The paddocks are flooding and it takes a while for the water to drain away so we have to take the cows off a little bit more than we’re used to so there’s certainly no weight gain on the cows at the moment.”

Van de Ven said there was not enough grass around but he was lucky that he had a really good summer and made a lot of silage.

Weather Watch duty forecaster Philip Duncan said things were not going to get much better anytime soon.

“It looks as though there’s at least 60 to 100 millimetres of rain coming to the Waikato in the next four weeks, mostly due to low pressure still crossing over the South Island and some parts of the country.

“And obviously with more westerlies blowing, that does encourage that rain to go all the way up the North Island, so Auckland and Northland will also get rain but it does seem that the heaviest falls will hit Waikato southwards down towards Taranaki and the west coast of the South Island.”

Modifying genes to increase dairy cows’ resistance to heat

Average summer temperatures and the frequency of ‘severe heat days’ are rising in several regions of the globe.

Dairy animals on pasture are hence more susceptible to heat stress. Smaller cow breeds, such as the Guernsey, outperform larger ones, such as the Holstein, although coat type and colour also have a factor.

So far, there are two ways to modify the coat via gene editing to boost heat tolerance. First, consider the’slick coat,’ which consists of short, silky, and occasionally even shiny hair.
The characteristic of a slick coat

Holsteins with a smooth coat have superior heat tolerance, as seen by lower internal (vaginal) temperatures and respiration rates. Researchers from Mississippi State University and the University of Puerto Rico in Mayagüez released a report in 2020 concluding that under the hot and humid circumstances of Puerto Rico, Holstein cows with the slick gene outperform those without it in terms of reproduction.

When compared to qualities including several genes, the smooth trait involves a single dominant gene, making it ideal for gene editing. According to Dr Alison Van Eenennaam, a scientist at the University of California, Davis, gene editing entails directing enzyme’scissors’ to make a targeted, particular cut in a DNA sequence. “Depending on how that’s repaired, you can have inactivation of the gene located at that point on the strand, or a difference in how the gene functions,” she adds. “DNA from that organism, another of its species, or another species may also be introduced.” Van Eenennaam employed gene editing to make a bull calf with more than 50% male progeny.

The’slick coat gene’ was introduced into freshly fertilised eggs from cows lacking the gene by geneticists at the Roslin Institute (University of Edinburgh in Scotland). Modified embryos were implanted in surrogate mother cows, and calves with glossy coats (but no other alterations) were born.

The research believes that applying this gene change has a high potential for increasing cow herds that are better acclimated to heat stress across the globe, and that it would be particularly beneficial to small-holder farmers in tropical nations. They are currently collaborating with colleagues at Kenya’s International Livestock Research Institute on local cow breeds.

According to team member Dr. Appolinaire Djikeng, “we can do small edits in the genome that very quickly accomplish improvements that would otherwise take 20 generations.” “I am very excited about the potential application of this technology in Kenya, the United Kingdom, and other parts of the world.”
Another clever gene editing experiment

Meanwhile, a company in the United States called Recombinetics has utilised gene editing to create two beef calves with the smooth coat feature. The US Federal Drug Administration (FDA) issued its first verdict on gene-edited cattle pertaining to this gene modification in March 2022, calling it a ‘enforcement discretion determination.’ This implies that the FDA judged that the ‘risk’ connected with these calves and their gene edit was minimal, therefore they are exempt from the implementation of current US gene editing restrictions. The FDA now defines any genetic mutation to an animal by gene editing as a novel animal medication, and so US drug regulation standards apply. In the future, gene-edited animals in the United States may be governed by the US Department of Agriculture rather than the FDA, which now controls gene edits to plants that include the inactivation of a gene or any gene that may have been introduced via normal breeding.

Van Eenennaam speculates that “the FDA could consider a tiered system with risk levels.” And it will be shortly. We must keep in mind that postponing gene editing research and commercialization comes at a high cost.”

Other nations, like Brazil, Australia, and Argentina, see gene editing as regular breeding when a gene is knocked out and no new DNA is introduced.

Dr. Tad Sonstegard, President and CEO of Acceligen (owned by Recombinetics), said that the company would continue to work towards the commercialization of cows with the slick gene modification in the United States.
More heat with a black coat

Changes in coat colour are another method gene editing is being utilised to minimise heat stress in cattle. Unlike other light-colored dairy breeds such as Jersey, the Holstein cow has a black and white coat, with some of the breed having a lot of black – and dark colours absorb substantially more UV radiation than lighter.

A team of geneticists in New Zealand has previously done this with Holsteins, utilising a gene modification to eliminate the black coat hairs. The AgResearch, Ruakura Research Centre, University of Auckland, Auckland, Maurice Wilkins Centre for Molecular Biodiscovery, Massey University Manawatu, and the Livestock Improvement Corporation are all part of the team.

They explain in their research that they induced a deletion in Holsteins in “the pre-melanosomal protein 17 gene, which has been proposed as the causative variant for the semi-dominant colour dilution phenotype observed in Galloway and Highland cattle.” Calves born from cells with homozygous edits have a unique grey and white coat pattern.”

“While we have demonstrated it for a dairy breed, the strategy could easily be applied to beef breeds such as Black Angus,” they say. Overall, our research demonstrated and confirmed genome editing as a viable new strategy for rapidly adapting cattle to changing environmental circumstances.”
Other genes associated with heat

Meanwhile, experts at Agriculture Victoria in the Australian state of Victoria have found many genes highly connected with heat tolerance.

Since 2017, Dairy Australia and the country’s dairy industry have made genomic breeding values for heat tolerance accessible to dairy producers via DataGene, an independent entity administered by Dairy Australia and the dairy industry.

Milk income-maximizing feed variables

Regardless of the feeding strategy utilised, efficient herd feeding is a critical aspect affecting dairy farm profitability. According to Dairy Australia, increasing the supply of home-grown feed is critical.

Research from throughout the globe, including Australia, has consistently shown a correlation between greater amounts of home-grown feed and better profitability. This is true independent of the farm’s feeding strategy or degree of intensity.

Dairy Australia underlines that, in the great majority of circumstances, locally produced feed is less expensive than imported or purchased feed. Maximising the production and exploitation of this resource is thus crucial to the sustainability of agricultural companies. Improving the resilience and profitability of agricultural systems requires increasing the production of home-grown feed.

Dairy Australia has produced a data sheet outlining the five most frequent feeding techniques used on dairy farms in Australia. Despite the fact that farms tend to get more intense from system 1 to system 5, there is a common misconception that home-grown feed is less important in more intensive systems.

“This is incorrect,” Dairy Australia points out, “as most successful examples of system 5 – where cows are fully housed – still grow a large percentage of their feed as home-grown feed, often as high-quality conserved forage such as maize silage or similar.”
Supplements are quite lucrative.

According to Dairy Australia, no system is superior to others, and all systems may be successful. Choosing the correct system for your farm will be primarily determined by the resources available and your risk tolerance.

On Australian dairy farms, home-grown feed seldom meets all of the feed gaps, thus supplements are employed. If utilised appropriately and effectively, they may be quite rewarding.

Dairy Australia has also prepared a ‘Designing balanced milker diets’ information sheet, which details how to optimise milk revenue minus feed costs in the herd and aids in the design of high-quality, nutritionally balanced milker diets.

Dairy Australia emphasises the need of farmers calculating cows’ daily food requirements. Cows need nutrient-dense diets for maintenance, pregnancy, exercise, growth, reproduction, and milk production. Although water, calories, protein, and fibre are the most important elements to consider when designing a diet, minerals and vitamins should not be overlooked.

Dairy Australia advises dairy farmers to consider several factors when selecting feeds to use in milker diets, including nutrient specifications, price, consistency of supply and quality, expected losses during storage (shrinkage), mixing and feed-out, increased capital requirements, extra labour required to handle, and other costs.

Milk earnings minus feed costs

The nutritional properties of feeds may vary greatly. The best approach to determine a feed’s nutritional properties is to get a feed test analysis. “High forage quality is paramount when designing diets for milking dairy cows,” states Dairy Australia. “Forage quality has a significant influence on feed intake because it is defined by its percentage of neutral detergent fibre [NDF] and NDF digestibility values.” The reaction to concentrates and diets is driven by forage quality.”

When developing a diet, farmers should consider three factors:

NDF digestibility and forage NDF percentage
The digestibility of starch in the rumen
Protein content and rumen degradability

According to Dairy Australia, an excess of nutrients may harm cow health, diminish feed conversion efficiency (kg of milk per kg of feed), and reduce milk revenue minus feed cost. “On the other hand, severe underfeeding will have an impact on performance as well as cow health and fertility.” It may take many cycles to balance the major components of a diet and discover a diet that is within the cow’s hunger limit and provides the highest potential milk revenue minus feed expense.”

Milk revenue less feed costs is a valuable indicator, according to Dairy Australia, especially when there is little or no pasture available. “It tells you how much of your milk income remains after you’ve paid for feed.” This sum must include running expenses such as herd, shed, labour, and administrative expenditures, as well as your finance and capital costs, including drawings.”
Efficiency evaluation

Farmers that feed a substantial quantity of purchased feed must obtain a high daily milk output per cow in order to get a higher milk revenue minus feed expense. The greater the milk output, the lower the proportion of unproductive money, that is, money spent on cow upkeep rather than milk production and income generation.

According to Dairy Australia, the concepts of marginal vs average milk output response are particularly important to grasp when administering supplements to optimise profit. The incremental increase in milk supply produced from an additional kilogramme of supplement provided is known as marginal milk response. The increase in milk supply averaged across all kilogrammes of supplement provided is referred to as the average milk response.

Dairy Australia believes it is critical to monitor the efficiency with which feed is transformed into milk since feed costs such a substantial amount of variable and total expenses on a dairy farm. Feed conversion efficiency (FCE) is a major indicator of a dairy farm’s feeding system performance, influencing feed cost per unit of milk and milk operational profit.

FCE is another major component that influences a farm’s greenhouse gas emissions. “FCE should always be used in conjunction with other farm physical and financial performance measures such as annual milk operating profit and return on assets,” Dairy Australia advises.

FCE is defined as the quantity of milk produced per kilogramme of feed fed to the herd. FCE for the milking herd may be calculated yearly or periodically throughout each year. “FCE is a useful form of measurement for monitoring the efficiency of a feeding programme,” according to Dairy Australia. “However, it should not be associated with farm profit too closely because it does not account for the cost of feed consumed by the herd.” FCE is useful in determining the quality of feed ingested by the herd, especially the forage component of the diet, since greater FCE is linked with better quality diets.”

Using selective breeding to reduce the risk of retained placenta in dairy cows

Retained placenta is a common reproductive condition in dairy cows, described as the inability to release foetal membranes within 24 hours following parturition, which increases the risk of uterine infections and infertility.

Due to increased culling risk, poorer reproductive performance, extended calving interval, higher veterinary expenditures, and decreased milk supply, retained placenta causes an estimated financial loss of US$ 150 to US$ 386 per cow every lactation. Previously, the emphasis was mostly on production and conformation qualities, which resulted in diminishing trends in health, reproduction, and lifespan features.

Although retained placenta has a modest heritability of 0.01 to 0.10, long-term selection on this reproductive abnormality may enhance resistance and boost herd profitability.

Risk hazards unique to cows

A lack of immunological function is one of the probable risk factors for retained placenta, since cows with retained foetal membranes have decreased neutrophil activity, which may affect their capacity to evacuate the placenta following parturition. Because of a shortage of dietary carotene, retained placenta is more common in the winter than in other seasons. Furthermore, shorter gestation durations and increasing parity are linked to a greater prevalence of retained placenta.

Retained placenta resistance

The anticipated resistance of dairy cow progeny to retained placenta in a herd with typical management circumstances is represented by resistance to retained placenta predicted transmission ability. The resistance rate is calculated by subtracting the incidence rate from 100. The average resistance rate in US Holsteins is 96%. Daughters of a Holstein bull with a predicted resistance to retained placenta of +2% are expected to have an average resistance rate to retained placenta of 98%, while daughters of a Holstein bull with a predicted resistance to retained placenta of -2% are expected to have an average resistance to retained placenta of 94%.

Furthermore, daughters from the bull with a projected transmitting capacity of -2% are likely to have three times the number of instances of retained placenta as daughters from the bull with a predicted transmitting ability of +2%.

Advantages of Choosing

Because retained placenta is a frequent risk factor for later metritis, improving resistance to retained placenta enhances resistance to metritis. Furthermore, retained placenta keeps the cervix open, which acts as a physical barrier to infection in unaffected animals. Retained placenta postpones uterine involution, lochia evacuation, and endometrial regeneration, and raises the risk of ovarian cystic degeneration, chronic endometritis, and pyometra.

However, the phenotypic occurrence of retained placenta reduces the afflicted dairy cow’s future milk output, and there is an antagonistic genetic association between retained placenta features and milk yield as well. Thus, improving resistance to retained placenta not only decreases the direct and indirect expenses associated with this condition, but it also improves dairy cow health, welfare, and reproductive performance.

Other reproductive problems

The discovery of a genetic link between retained placenta and other reproductive problems simplifies breeding for enhanced resistance to retained placenta. According to a research published in 2022 by Mahnani and colleagues, the estimated genetic connections with retained placenta were -0.04 for twinning, 0.32 for stillbirth, and 0.34 for dystocia. These findings suggest that twinning reduces the likelihood of retained placenta, and that selecting against retained placenta may indirectly select against dystocia and stillbirth.

Furthermore, modest genetic associations between retained placenta and dystocia and stillbirth show that cows that are vulnerable or resistant to retained placenta are genetically more susceptible or resistant to dystocia and stillbirth. The estimated genetic associations between retained placenta and production parameters such as milk, fat, and protein yields varied from -0.12 to -0.29 in this research, indicating that cows with greater output during early lactation are less likely to acquire retained placenta. The researchers also discovered a low negative genetic link (-0.09) between retained placenta and success of first insemination, but a significant positive genetic correlation (0.25) between retained placenta and days open, days from calving to first service, and number of inseminations per conception.

These findings indicate that dairy cows with retained placentas had longer days open, days from calving to first service, a higher number of inseminations per conception, and worse first insemination success. As a result, genetic selection against retained placenta enhances reproductive features.

Genetic regulation

When combined with appropriate management practises, improving disease resistant features via direct genetic selection gives a compelling potential for dairy farmers to better reduce disease incidence and enhance profitability. A helpful on-farm management tool is genomic prediction for health features such as resistance to retained placenta gained at a young age.

Genetically better heifers and cows may be bred with sexed sperm, whereas genetically inferior animals can be sold for meat early or bred with beef sperm. It is advised to assess the accuracy of genetic calculations in predicting the performance of each dairy cow. Furthermore, information gathered from commercial dairy herds may be utilised to correctly predict resistance features in dairy cows.
Conclusion

Retained placenta is a costly condition that impacts the health, welfare, and profitability of 7.8% of US dairy cows. To enhance dairy cow health, welfare, and performance, the genetic study of retained placenta and its relationship with other reproductive diseases, fertility, and production attributes must be prioritised.

More research is needed to examine health features and their relationship to retained placenta in order to properly classify dairy cows based on herd profitability.

How to to Boost Performance and Lower Feed Costs

Feed expenses will remain the most expensive item. Dr. Mike Hutjens, retired professor of animal science at the University of Illinois-Champaign-Urbana, points out that feed expenditures are the most expensive aspect of farming.

“With feed accounting for half of total farm expenses, keeping them under control is critical,” he explains. “The only reason to raise livestock is to increase the return on crops raised on the farm.”

Gary Sipiorski, an independent farm company finance expert, believes that understanding your expenses is critical. According to him, feed prices vary from 20% to 45% of total revenue, depending on how much feed you generate yourself.

“If you buy all of your feed, your feed costs will be around 50% of your milk check,” Sipiorski explains. “Feed is the most expensive cost for a dairy, and each farm must evaluate it individually based on variables such as needs and forage quality.”

Jim Salfer, a University of Minnesota Extension dairy specialist, gives some best practises to assist farmers reduce feed expenditures. In most herds, these guidelines may be adopted with minimum impact on performance.

  1. Reduce Waste and Shrink – A 100-cow dairy may save $58,400 in one year by switching from high to low shrink. Dairies often experience 30% shrinkage on forages with bunkers and piles, and 10% shrinkage on concentrates in commodity sheds. “This is the most significant and simple way to reduce feed costs,” he adds, adding that fodder held in bunkers or heaps is an insidious cost since you don’t pay for it.
  2. Work with your nutritionist to maximise the benefit of homegrown feeds if you raise the majority of your own feeds, he advises. “If you feed purchased dry hay, consider reducing the amount and increasing the corn silage in the diet if you have an adequate supply.” “Even if purchased protein costs more, the total diet cost is likely to be lower,” Salfer notes.
  3. Optimise Bunk Refusals — “Many have successfully reduced bunk refusals to 2% or less for lactating cows with excellent bunk reading and feed management.” “In a freestall barn, feed can be fed to replacement heifers or the low group,” he explains. As the number of refusals decreases, Salfer emphasises the need of high-quality meals, regular pushups, feed-maintenance methods, and consistent feeding hours.
  4. Avoid Nutrient Overfeeding —All kinds of animals should be fed at indicated nutrient needs, but no more. Heifer diets that are much beyond national research council standards, in my view, are a waste of nutrients. “Research shows that feeding at recommended levels is adequate for excellent growth,” adds Salfer. “Review additives and determine if they are cost-effective in the diet.”

 

The dos and don’ts of ketosis for dairy cows

Ketosis is a frequent transition condition that affects 5-80% of dairy farms. Ketosis is characterised as a high concentration of ketone substances in all bodily fluids, such as acetone, acetoacetate, and beta-hydroxybutyrate. Anorexia, reduced milk supply, loss of body condition, hard, dry stools, and rarely neurologic symptoms are clinical indicators of ketosis. This article discusses the dos and don’ts of ketosis management.

Other transition cow illnesses like as metritis, retained placenta, and left displaced abomasum have been linked to ketosis. Monitoring the herd’s degree of ketosis may therefore help to avert these economically important illnesses.
Ketosis monitoring in the dairy herd

It is critical to test enough animals in the herd to monitor the fresh cow incidence of ketosis. A reasonable approach would be to test 12-15 cows. If more than 10% of the cows have ketone levels higher than the established limit of 14.4 ml/dL, the group is said to be in ketosis.
Sufficient bed space and stocking density

Negative energy balance around the time of calving causes adipose mobilisation and ketone body formation because to increased energy demand from milking production and reduced dry matter intake. As a result, it is critical to address the conditions that contribute to decreased dry matter intake, such as bunk space and stocking density.

The minimal sleeping space per head is 24 inches, while the optimum bunk space per head is about 30 inches. The recommended bedded pack area per head is between 120 and 150 square feet (11-14 square metres), while free stall stocking density must stay at one cow per stall.
Pay attention to the dry time.

The dry phase in dairy production systems lasts 60 days and includes both far-off and close-up periods. The pregnant cow is given a break from milking before to the next calving during the dry season to recover body reserves and rebuild milk-secreting tissue after months of milking.

According to research, failing to provide a dry time for a cow lowers milk production in the next lactation by 25-30% and increases the risk of metabolic disorders such as ketosis and milk fever, as well as problems such as displaced abomasum. Furthermore, appropriate dry period management requires accurate record-keeping.
Collaboration with veterinarians and dietitians is essential.

Veterinarians and nutritionists work with dairy producers to detect and manage potential causes of ketosis. Veterinary treatment and preventative procedures must be considered. Subclinical ketosis, for example, may be treated with 300 mL of propylene glycol orally once every day for 3-5 days.
Body condition evaluation

Body condition rating is a useful instrument that has a substantial influence on transition performance and ketosis prevalence. The optimal post-calving body condition score varies from 2.75 to 3 out of 5.

During the transition phase, low and high body condition scores increase the risk of ketosis and have a negative influence on reproductive performance. As a result, it is important to frequently assess the body condition score during dry-off, moving to close-up, calving, and moving out of the fresh pen.
Cows and heifers should not be mixed.

Co-mingling heifers and older cows increases heifer stress, reduces dry matter intake, and contributes to a negative energy balance. Furthermore, in dairy herds, there is a social order, and transferring a cow into a new enclosure with animals it is unfamiliar with might cause further stress. in a result, it is advised that the cows be moved in a group so that they may be with other familiar cows.
Do not overfeed dairy cows.

Each stage of dairy production necessitates a different approach to feeding. Because the cow isn’t being milked during the dry time, too much energy in diet must be avoided. Furthermore, concentrates and grains promote fat accumulation and predispose the animal to difficult births, ketosis, udder edoema, downer cow syndrome, and abomasum displacement.

Dairy cows need a sufficient supply of calories, proteins, minerals, and vitamins. Furthermore, trace minerals promote a stronger immunological response after calving and the transition period, enhancing a cow’s inflammatory response and lowering the incidence and severity of ketosis.
