Discovering the Hidden Benefits of 25-Hydroxy D3 Supplements for Dairy Cow Health

Learn about the benefits of 25-Hydroxy D3 supplements for dairy cows. How can this improved form of vitamin D boost cow health, strengthen immunity, and improve overall performance?

Do you think vitamin D is just about sun exposure and bone health? Think again. New research suggests that 25-hydroxy D3 supplementation may significantly improve the health of dairy cows. This finding, similar to the discovery of vitamin D in the 1920s, has the potential to improve dairy cow health and output dramatically. It is critical for keeping calcium levels stable in all animals, especially dairy cows. Cows with low calcium levels may have milk fever, which may cause muscular difficulties.

But vitamin D’s effects extend beyond the bones. It helps prevent cancer and, more significantly, strengthens the immune system. Enter 25-hydroxy D3, a more straightforward vitamin D for cows to absorb, improving overall health. This new supplement enhances calcium recovery and serves as a shield, reinforcing dairy cows’ immune systems. This improvement in dairy farming promises a healthier herd.

So why should you care? Healthy cows provide better milk, resulting in safer and higher-quality dairy products. Embracing the advantages of 25-hydroxy D3 may help the dairy business and encourage sustainability.

Unveiling the Power of Vitamin D: A Century of Calcium Mastery and Dairy Health. The potential of 25-hydroxy D3 supplements to transform dairy herd management is a testament to the continuous evolution of dairy farming practices.

The potential of 25-hydroxy D3 supplements to improve dairy herd management demonstrates the ongoing development of dairy farming operations. Vitamin D was discovered in the early 1920s while researchers studied rickets, a calcium shortage condition. They noticed that sunshine exposure may prevent rickets, which led to the discovery of vitamin D’s critical function in calcium homeostasis. Maintaining adequate calcium levels is crucial for dairy cows’ health and output. Vitamin D promotes calcium absorption from the stomach. Nonetheless, without enough of it, cows risk experiencing milk fever, which inhibits muscular function owing to low blood calcium levels.

The Critical Role of Vitamin D in Dairy Cow Calcium Homeostasis 

Vitamin D is essential for maintaining calcium levels and performing normal physiological processes. It helps dairy cows absorb calcium from their food. Cows cannot absorb calcium properly if they do not have enough vitamin D, which causes shortages.

A significant issue is milk fever, caused by low blood calcium levels at calving time. This occurs when the cow requires more calcium for milk production but cannot move enough, resulting in muscular weakness and limited mobility. In extreme circumstances, it may be lethal.

Vitamin D prevents milk fever by controlling calcium levels, increasing calcium absorption from the stomach, and mobilizing calcium from bones. However, although vital, vitamin D alone is insufficient to prevent milk fever. Maintaining stable calcium levels requires a complete strategy, including dietary modifications and mineral supplementation.

The Limitations of Vitamin D3 Conversion in Dairy Cows: What You Need to Know

Though this mechanism is limited, dairy cows may convert vitamin D3 from sunshine or supplementation to 25-hydroxy D3. This conversion occurs in the liver, where enzymes convert vitamin D3 to 25-hydroxy D3, the precursor of active vitamin D. This form circulates in the circulation and promotes calcium metabolism. However, the liver can only synthesize a certain amount of 25-hydroxy D3 at a time. Once this limit is reached, excess vitamin D3 is not metabolized correctly, resulting in lower-than-optimal amounts of 25-hydroxy D3 in the blood. This constraint is critical during the prenatal and postnatal periods when dairy cows need appropriate calcium management. This knowledge of the conversion process emphasizes the need for 25-hydroxy D3 supplementation in preserving cow health.

The Journey to 25-Hydroxy D3 Supplements in Dairy Cows: Bridging Nutritional Gaps 

Introducing 25-hydroxy D3 supplements significantly advances animal nutrition, particularly for ruminants. These supplements have been utilized in poultry for over 30 years, although their usage in dairy cows is relatively recent. Europe has just recently legalized their usage. However, several nations have been using them for the previous five to ten years. So, why is there a wait for dairy cows?

Two major elements led to this. First, there needs to be more urgency. Poultry have a harder time absorbing vitamin D3; thus, 25-hydroxy D3 tablets are especially effective. Second, it was considered that ruminants could metabolize enough vitamin D3 to 25-hydroxy D3, making supplementation unnecessary.

However, a new study has indicated that ruminants cannot convert vitamin D3. This finding has increased interest in 25-hydroxy D3 supplementation for dairy cows, which may enhance calcium metabolism and general health. These supplements are helpful when cows’ vitamin D3 conversion is insufficient, such as in the prepartum period.

This comparison of poultry and dairy cows demonstrates their different dietary requirements and reactions. These supplements have been approved, allowing dairy producers to have healthier herds.

Vitamin D3 vs. 25-Hydroxy D3: The Biochemical Edge for Animal Health 

Understanding the difference between vitamin D3 and 25-hydroxy D3 is essential for animal health. Vitamin D3, or cholecalciferol, is created in the skin when exposed to sunshine, but it must be converted before it becomes physiologically active. This process begins in the liver, where vitamin D3 is converted into 25-hydroxy D3 (calcidiol) by attaching a hydroxyl group (-OH) to the 25th carbon of the vitamin D3 molecule. This change considerably increases the action of the vitamin, making it more beneficial to the cow’s health.

The procedure includes attaching a hydroxyl group (-OH) to the 25th carbon of the vitamin D3 molecule, dramatically increasing its activity. Supplementing dairy cows directly with 25-hydroxy D3 avoids the liver stage, making the vitamin instantly accessible.

This direct supplementation assists animals that cannot convert enough vitamin D3 to 25-hydroxy D3, resulting in efficient and quick absorption in the circulation and improved health results.

Maximizing Efficiency: Why 25-Hydroxy D3 Outshines Vitamin D3 in Dairy Nutrition

Regarding efficiency, 25-hydroxy D3 is better absorbed by the body than vitamin D3. Its enhanced form avoids the liver’s conversion step, making it easily accessible for metabolic functions in dairy cows.

Studies have shown that lesser dosages of 25-hydroxy D3 reach blood levels comparable to greater doses of vitamin D3. Experiments with Holstein dairy calves revealed that half the dose of 25-hydroxy D3 produced identical blood concentrations as vitamin D3. This implies improved absorption and cost-effectiveness.

Dairy cows fed with 25-hydroxy D3 may maintain good health at lower doses. In the United States, rules allow up to three milligrams during the prepartum period, but Europe allows just one milligram. Higher blood 25-hydroxy D levels improve various physiological activities, including the immune system, demonstrating the greater effectiveness of 25-hydroxy D3 supplementation.

Beyond Calcium: Unleashing the Immune-Boosting Power of 25-Hydroxy D3 in Dairy Cows

While the link between vitamin D and calcium is widely understood, the advantages of 25-hydroxy D3 extend considerably further. This metabolite is essential in the immune system because it aids in producing antimicrobial peptides and regulating inflammation, both of which are necessary for general health. Furthermore, 25-hydroxy D3 promotes quicker calcium repair in dairy cows. While it does not prevent milk fever, it may speed up the recovery of calcium levels in cows experiencing hypocalcemia, which is crucial for muscular function and general vitality. 25-hydroxy D3’s anti-inflammatory effects help dairy cows recuperate from stress and increase milk production. This makes 25-hydroxy D3 an essential supplement to dairy nutrition since it promotes bone health, a robust immune system, and quick recovery.

Pioneering Research on Maternal and Fetal Vitamin D: Unlocking Lifelong Health for Dairy Herds

Researchers are studying how maternal and fetal vitamin D metabolism, namely vitamin D3 and 25-hydroxy D3, impact fetal growth and development. They are investigating the effects on skeletal and immune system development. Studies look at how these supplements affect the fetus’s development and immunological resilience, paving the way for better health outcomes throughout the animal’s lifetime. Scientists want to understand better how these approaches improve dairy cows’ overall performance and production by monitoring their impacts throughout gestation and early life. This study suggests that early nutritional adjustments may improve the health and efficiency of dairy cows over time.

The Bottom Line

The finding of 25-hydroxy D3 supplements represents a significant advancement in dairy cow health management. These supplements are a more effective and robust alternative to typical vitamin D3, addressing conversion difficulties in dairy cows.

We’ve seen how vitamin D affects calcium control and the distinct advantages of 25-hydroxy D3. These supplements improve calcium recovery after childbirth, strengthen the immune system, and minimize inflammation. 25-hydroxy D3 may improve health outcomes at lower doses than vitamin D3.

The significance of integrating 25-hydroxy D3 into dairy nutrition is evident. Research on maternal and fetal health highlights potential advantages for dairy herd management throughout the lifetime. Embracing 25-hydroxy D3 improves dairy nutrition and promotes healthier, more productive cows.

Investing in this study and using these findings may result in larger, healthier dairy herds. Now is the moment to connect our operations with the most recent scientific advances to ensure the health of our herds.

Global Dairy Cattle Diseases Cost $65 Billion Annually: India, US, and China Hit Hardest

Learn how dairy cattle diseases cost the world $65 billion every year. Which countries suffer the most and why? Uncover the detailed findings now.

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

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

Though these costs vary greatly worldwide, “the total annual global losses due to dairy cattle diseases are greatest in India, the US, and China.”

Investigate the financial ruin dairy cow illnesses like mastitis, ketosis, and lameness cause. This study provides a thorough worldwide view and uncovers why specific ailments are more expensive than others.

The Hidden Costs of Dairy Cattle Diseases: An In-Depth Global Economic Analysis

Under the direction of Philip Rasmussen of the University of Copenhagen, a team of researchers has conducted a thorough and innovative study reported in the Journal of Dairy Science that offers a comprehensive worldwide economic evaluation of dairy cow illnesses. Examining statistics from more than 180 milk-producing nations, the research painstakingly examines the financial impact of 12 major dairy cow illnesses and health issues. The researchers not only precisely calculated the worldwide losses using a comorbidity-adjusted technique but also guaranteed that any overlaps in illness effects were considered, hence providing a more accurate estimate. This thorough investigation emphasizes the global broad and different economic load dairy cow illnesses cause.

Twelve major dairy cow diseases, including mastitis (subclinical and clinical), lameness, paratuberculosis, displaced abomasum, dystocia, metritis, milk fever, ovarian cysts, retained placenta, and ketosis (clinical and subclinical), were investigated economically. These illnesses raise culling rates, affect milk output, and change reproductive rates. Precise approximations of their effects enable improved control and lower financial losses.

With a comorbidity-adjusted economic analysis, the researchers painstakingly calculated the cost of dairy cow illnesses. They considered characteristics like milk output, fertility, and culling rates, and compiled data on twelve illnesses from literature covering over 180 milk-producing countries. They standardized these measures for consistent comparability across research to guarantee dependability. This rigorous methodology ensures the accuracy and reliability of our findings.

They then combined these datasets into thorough estimations using sophisticated meta-analysis methods ranging from basic averaging to complicated random-effects models. Correcting for comorbidities was essential to avoid overestimation and to recognize the concurrent incidence of many illnesses with their combined financial consequences.

Equipped with these consistent projections, the group modeled the financial influence using Monte Carlo simulations. They precisely estimated the economic losses by including country-specific data on illness incidence, lactational prevalence, herd features, and economic criteria.

This study depends on adjusting for comorbidities to guarantee that overlapping health problems do not distort the economic effects of different illnesses. Dairy cow infections often coexist and cause combined health problems that distort statistics. Considering these comorbidities helped researchers to estimate the cost more precisely. Without this change, 45% of the worldwide losses would have been exaggerated, distorting the actual economic weight of the dairy sector. This change offers a more accurate knowledge of the financial effects related to illnesses of dairy cattle.

Dairy Cattle Diseases: A $65 Billion Annual Burden with Subclinical Ketosis and Mastitis Leading the Costs

According to an extensive analysis of dairy cow illnesses, yearly worldwide losses amount to US$65 billion. Most importantly, subclinical ketosis, clinical mastitis, and subclinical mastitis surfaced as the most expensive causes of mean annual worldwide losses, ranging from US$18 billion to US$13 billion and US$9 billion, respectively.

In China, the United States, and India, dairy cow illnesses have a negative economic influence. With $12 billion yearly losses, India’s dairy industry’s great size emphasizes the necessity of improved disease control, and the country suffers the most. Veterinary expenses, decreased milk output, and early culling cause the United States to lose $8 billion annually. With China’s industrial-scale dairy production and rising demand for dairy products, its $5 billion losses reflect its industrial nature.

The financial burden of these losses is defined by various measures. When viewed as a proportion of GDP, India’s agricultural economy bears the brunt, highlighting the need for tailored disease control plans. Analyzing losses per capita or as a proportion of overall milk income offers another perspective. The high dairy output quantities underscore the potential for significant financial losses even with a low frequency of illness. This underscores the necessity of customized disease control plans, designed to fit the unique architecture and economic situation of each nation’s dairy sector.

The Bottom Line

This study emphasizes the important role that legislators, scientists, and dairy industry stakeholders play globally. With nearly half of these costs ascribed to subclinical ketosis, clinical mastitis, and subclinical mastitis, it exposes the shockingly high financial cost of dairy cow diseases—$65 billion yearly. The research shows how urgently policies and focused treatments are needed. Countries with the most losses—China, the US, and India—have to lead in putting sensible disease management strategies into effect. Best agricultural techniques, better veterinary care, and strong monitoring systems may help to greatly reduce these losses. All those involved must recognize and solve these financial challenges, thereby guaranteeing the viability of the worldwide dairy sector.

Key Takeaways:

  • Global dairy cattle diseases lead to annual financial losses of approximately US$65 billion, affecting milk yield, fertility, and culling rates.
  • The most significant losses are observed in India (US$12 billion), the US (US$8 billion), and China (US$5 billion).
  • Subclinical ketosis, clinical mastitis, and subclinical mastitis were identified as the costliest diseases, with annual global losses of US$18 billion, US$13 billion, and US$9 billion, respectively.
  • When adjusting for comorbidities, the overestimation of aggregate global losses is reduced by 45%, highlighting the importance of considering disease interactions.
  • Disease-specific losses include lameness (US$6 billion), metritis (US$5 billion), ovarian cysts (US$4 billion), paratuberculosis (US$4 billion), and retained placenta (US$3 billion).
  • The relative economic burden of dairy cattle diseases varies significantly across countries, dependent on metrics such as GDP, per capita losses, and gross milk revenue.
  • Effective and customized disease control plans are essential to mitigate these substantial economic impacts.

Summary: Dairy cow diseases, causing $65 billion in yearly losses, are a global economic crisis affecting milk production, fertility, and farmers’ livelihoods. The largest losses are in India, the US, and China. A study by Philip Rasmussen of the University of Copenhagen evaluated the financial impact of 12 major dairy cow diseases, including mastitis, lameness, paratuberculosis, displaced abomasum, dystocia, metritis, milk fever, ovarian cysts, retained placenta, and ketosis. These diseases increase culling rates, affect milk output, and change reproductive rates. India’s dairy industry suffers the most, with $12 billion yearly losses. The US loses $8 billion annually due to veterinary expenses, decreased milk output, and early culling. China’s industrial-scale dairy production and rising demand result in $5 billion losses.

Discover the Unique Nutritional Needs of Jersey Cows

Discover how to maximize efficiency and health in Jersey cattle. Learn about their unique nutritional needs and how to address them effectively.

Holsteins are known for high milk volume, while Jerseys shine for quality and adaptability. Their smaller size and unique traits make them valuable assets. However, they have distinct nutritional needs that require careful attention to optimize health and efficiency.  Jerseys excel in producing nutrient-rich milk and are incredibly efficient in feed conversion and land use. Addressing their specific requirements can boost milk quality , which refers to the composition and characteristics of the milk, and herd health, making them essential for sustainable and profitable dairy farming.

Jersey Milk: Nutrient-rich, Flavorful, and Versatile for Health and Culinary Applications

When it comes to dairy, the nutritional quality of milk significantly impacts consumers. Jersey milk, boasting higher protein, milkfat, and calcium than Holstein milk, is a standout choice. Its increased protein levels aid muscle maintenance and repair, crucial for active and aging individuals. A higher milkfat percentage promotes the absorption of fat-soluble vitamins essential for overall health. Additionally, elevated calcium content strengthens bones and teeth, making Jersey milk ideal for boosting family nutrition. This superior quality of Jersey milk instills confidence in dairy professionals about the value they provide to consumers. 

“The nutrient density of Jersey milk provides essential nutrients in higher quantities and enhances its culinary versatility. Chefs and home cooks prefer Jersey milk for its rich texture and flavor, which can elevate both sweet and savory dishes.”

  • Improved Nutritional Profile: More protein for muscle health and milkfat for vitamin absorption.
  • Culinary Excellence: Superior taste and texture favored by chefs.
  • Enhanced Bone Health: Increased calcium supports strong bones.

Jersey milk’s unique nutritional composition also benefits beyond essential dairy consumption. Cheese, yogurts, and other dairy products made from Jersey milk often offer exceptional taste and quality, favored by consumers and chefs alike. This versatility and value highlight why Jersey Milk’s milk’s nutritional characteristics are indispensable.

Jerseys: Small Stature, Significant Advantages for Dairy Operations 

Jerseys, with their smaller size than Holsteins, offer unique advantages to dairy operations. Their compact stature means they consume less feed and optimize barn space. Despite their smaller size, Jerseys excel in converting feed to milk with high protein, milkfat, and calcium levels. This unique trait empowers dairy farmers to maximize their resources and enhance their herd’s productivity. 

Jerseys also maintain a higher dry matter intake (DMI) after calving, which is crucial for meeting energy needs during lactation and reducing metabolic disease risks. Their increased chewing improves rumen stability and fiber digestibility, making them more efficient feed converters than other breeds.

Scientific Validation: Jerseys’ Superior Feed Conversion Efficiency 

Scientific research demonstrates that Jerseys are significantly more efficient than Holsteins at converting feed into milk components. Studies show that when producing the same amount of protein, milkfat, and other solids, Jerseys need 32% less water, use 11% less land, and consume 21% less fossil fuels. This efficiency highlights their minimal environmental impact

Moreover, Jerseys extract and utilize energy from their diets more effectively, leading to higher nutrient levels in their milk. A glass of Jersey milk contains 18% more protein, 29% more milkfat, and 20% more calcium than Holstein milk. This nutrient density underscores Jersey milk’s superior quality and enhances the breed’s value in the dairy industry.

Key Nutritional and Health Differentiations: Feed Intake, Energy Metabolism, and Overall Health 

When examining Jersey’s dietary and health needs, three areas stand out: feed intake and digestion, energy metabolism, and health. 

Regarding feed intake and digestion, Jerseys maintain a higher DMI post-calving relative to their body weight. This, alongside spending more time chewing, supports a stable rumen environment, enhancing fiber digestibility and feed conversion efficiency. 

In terms of energy metabolism, Jerseys extract more energy from their diet. Energy metabolism refers to the chemical reactions in the body that convert food into energy. Efficient energy metabolism is crucial for cow health and milk production, as it ensures that the cow’s energy needs are met. Jerseys’ ability to extract more energy from their diet means they require fewer resources than Holsteins, making them more environmentally sustainable. Their milk is richer in protein, milk fat, and calcium. 

Regarding health, Jerseys’ smaller size and robust hooves reduce lameness and disease risks. Their higher rumen pH offers better resilience against acidosis. However, fewer vitamin D receptors in their gut increase their risk for milk fever, necessitating careful DCAD management. 

Another critical difference is Jersey’s faster maturity rate, which increases their risk of becoming overweight. Effective strategies include housing them with older Holsteins to better match their nutritional needs and promote healthy growth.

Health Advantages: Why Jerseys Outshine Other Breeds in Dairy Farming 

Jerseys boast substantial health benefits, enhancing their appeal to dairy farmers. Their tiny, hard black hooves produce fewer lameness issues, like hairy heel warts, common among larger breeds. This durability ensures Jerseys are productive, reducing mobility issues and associated treatment costs. 

Additionally, Jerseys maintain a higher rumen pH, granting them better tolerance and quicker recovery from acidosis. This trait helps stabilize digestive health during stressful periods like calving, ensuring high feed efficiency and milk production without frequent digestive upsets. 

However, Jerseys are more susceptible to milk fever due to fewer vitamin D receptors in the gut, making them three times more likely to experience this condition than Holsteins. Milk fever, also known as hypocalcemia, is a metabolic disorder that occurs when the cow’s blood calcium levels drop rapidly after calving. It can lead to muscle weakness, reduced feed intake, and even death if not managed properly. 

Managing this requires proactive measures like monitoring dietary cation-anion difference (DCAD) and calcium mobilization strategies. Regular urine pH checks can help adjust prepartum rations. When current rations fall short, adding anionic salts can effectively prevent milk fever, safeguarding Jersey cow health and productivity.

Optimizing Health and Productivity through DCAD Monitoring and Glucose Enhancement in Jerseys 

To manage Jerseys effectively, it is crucial to monitor and adjust the dietary cation-anion difference (DCAD) and enhance glucose production. These strategies will help mitigate the risks of milk fever while supporting overall energy balance and immune function. 

  • Jerseys maintain higher dry matter intake (DMI) post-calving, aiding in rumen health and feed efficiency.
  • They are efficient feed converters, extracting more energy from smaller absolute feed intake.
  • Jersey milk is nutritionally superior, with higher protein, milkfat, and calcium than Holstein milk.
  • Jerseys mature faster, requiring careful feeding strategies to avoid overweight issues; housing with older Holsteins can help.
  • Jerseys have healthier hooves and higher rumen pH, reducing lameness and acidosis risks.
  • Monitor DCAD status closely to prevent milk fever, utilizing calcium mobilization strategies as needed.
  • Enhancing glucose production can mitigate negative energy balance and support immune function.
  • Breed-specific research is essential for optimizing Jerseys’ health and productivity.

First, consistently measure your cows’ urine pH, aiming for levels between 6.2 and 6.8. If current rations don’t achieve these levels, add anionic salts to the diet to improve calcium mobilization and prevent milk fever. Maintaining optimal DCAD is essential for Jersey’s health during its transition period. 

Enhancing glucose production is vital to counteract the negative energy balance seen postpartum. Increase the energy density of rations by using highly digestible forages and grains, and consider glucose precursors like propylene glycol or glycerol. These can be administered postpartum to address the energy gap, supporting energy reserves and immune function. 

Implementing these strategies requires careful observation and flexibility. Regular monitoring and timely dietary adjustments will help keep Jersey herds healthy and productive, meeting the demanding targets of modern dairy operations.

The Bottom Line

Jersey cattle have distinct nutritional needs that require special attention. Their efficient feed conversion, smaller size, and unique metabolism necessitate specific feeding and management practices to ensure optimal health and productivity. Addressing these requirements is crucial for the success and welfare of Jersey herds. By focusing on feed intake, energy metabolism, and health, farmers can maximize the potential of Jerseys, contributing to sustainable and profitable dairy farming. 

Utilizing Jerseys’ superior feed efficiency and unique health benefits, dairy farmers can boost milk production and overall herd welfare. Jerseys’ higher milk solids and lower environmental impact enhance their value in sustainable farming. Their resilience to certain health issues and energy efficiency make them an optimal choice for modern dairy operations. Adapting management practices to meet the specific needs of Jersey cattle will lead to healthier, more productive herds. 

I urge dairy farmers to integrate these tailored strategies into their operations. This will yield significant improvements in sustainability, productivity, and profitability. The future of dairy farming involves embracing the distinctive strengths of Jersey cattle, making them central to a thriving dairy industry.

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

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

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

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

Setting Your Sightlines

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

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

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

Fresh Cow Protocols Need the Right People and Protocols

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

CSI: Cow Scene Investigations

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

Note the Obvious First

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

  1. Down cow
  2. Difficult calving
  3. Twins
  4. Extremely fat cows at calving
  5. Obvious discomfort of difficulty moving.

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

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

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

Hindsight:  Don’t Be Blindsided by the Backside

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

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

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

The Benefits of a Well-Conceived Transition Program.

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

The Bullvine Bottom Line

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