Why “Crowded Cows” Are a Growing Concern: The Impact on Dairy Farm Production

Friday, July 19th, 2024

Uncover the obscured expenses associated with “crowded cows” in agriculture and animal welfare. What repercussions does this practice have on our food supply and the health of livestock?

Overcrowding in dairy production, sometimes called ‘crowded cows,’ has become a significant worry for agricultural communities. Farmers must prioritize herd care and enhance productivity to meet the increased demand for dairy products. Overcrowding harms cow health, reducing farm output and sustainability. It causes sickness, stress, inefficiencies in milk production, and greater death rates. Stress and lack of relaxation may lead to a 10% loss in milk supply, costing a farm up to $50,000 per year. However, tackling ‘packed cows’ and encouraging sustainable and humane dairy farming may help livestock and livelihoods while increasing the dairy industry’s economic sustainability.

The Consequences of Spatial Overload in Dairy Farming

Cow Density	Number of Stalls per Cow
Low (<80% stocking)	1.2
Moderate (80%-100% stocking)	1.0
High (>100% stocking)	0.8

Crowded cows occur when the number of animals exceeds the required space for their health, production, and well-being. This problem stems from a lack of bunk space, resting locations, and restricted supplies such as water and food. A dairy cow requires around one stall. For pasture operations, they need about 120 square feet per cow. Exceeding this limit has negative repercussions, including increased resource competition, reduced dry matter intake (DMI), and decreased milk production. However, farmers may dramatically increase their herds’ well-being and productivity by emphasizing cow comfort and following these geographical guidelines.

The Impact of Overcrowding on Dairy Cow Welfare: Stress, Health, and Behavioral Issues

Metric	Optimal Conditions	Overcrowded Conditions	Percentage Difference
Milk Production (liters/day)	25	18	-28%
Incidence of Mastitis (%)	10%	30%	+200%
Average Longevity (years)	6	4	-33%
Feed Conversion Efficiency	1.5	1.2	-20%

Overcrowded circumstances harm dairy cows’ welfare, causing physical pain and other issues. Competition for food and rest places leads to elevated stress levels, which may weaken immune function and increase susceptibility to illnesses like mastitis and respiratory infections. Crowded herds might lead to behavioral difficulties. Cows become more aggressive as they fight for space, inflicting injuries and disrupting herd peace. Stress and dissatisfaction may cause aberrant repeated behaviors like frequent licking and pacing, indicating significant welfare inadequacies.

Overcrowding Factor	Impact on Milk Production
Increased Competition for Food	Decreased nutrient intake, leading to lower milk yield
Elevated Stress Levels	Reduction in milk quality due to hormonal imbalances
Limited Resting Space	Reduced time for necessary rest and rumination, impacting milk production
Poor Ventilation	Higher susceptibility to respiratory diseases, adversely affecting milk yield.

The Ripple Effect: From Stress to Severe Health Complications in Dairy Cows

Overcrowding has significant health consequences beyond acute stress, including lameness, mastitis, and respiratory difficulties. These circumstances jeopardize dairy cows’ well-being and production while imposing significant economic expenses on producers. Lameness, caused by extended standing on hard surfaces and little rest owing to restricted space, hinders movement and lowers feeding, influencing nutrition and energy intake, both of which are critical for milk production. Poor mobility might lead to increased stress and decreased milk supply.

Mastitis, an inflammatory illness of the udder, is aggravated by overcrowding, significantly when hygiene standards deteriorate owing to overpopulation. This illness lowers milk quality and quantity, needing expensive veterinarian interventions and lengthy therapies. Respiratory problems are common in overcrowded barns with poor ventilation, promoting diseases that quickly spread across the herd and reduce output. Chronic respiratory difficulties often result in higher culling rates, lowering each animal’s lifetime and return on investment.

Finally, these health conditions considerably impair dairy cows’ productivity and lifetime, resulting in lower milk output, medical costs, and profitability. Overcrowding poses health risks that must be addressed to maintain a healthy dairy enterprise.

Compromised Milk Production: The Immediate Impact of Overcrowding

Overcrowding Level	Milk Production (lbs/day)	Impact on Production (%)
Optimal Conditions	70 lbs	0%
10% Overcrowded	67 lbs	-4.3%
20% Overcrowded	64 lbs	-8.6%
30% Overcrowded	60 lbs	-14.3%

Dairy overpopulation’s most immediate consequences are decreased milk output and quality. Keeping cows in confined quarters reduces their daily dry matter intake (DMI), resulting in inadequate nutritional absorption for optimum milk production. Cow rivalry intensifies with limited bunk space, prompting some to eat less feed.

Overcrowding triggers deep physiological stress reactions. Stress causes the production of cortisol, a hormone that disrupts reproductive systems and immunological responses. Chronic stress limits the release of oxytocin, which is required for milk letdown, reducing milk quantity and quality.

Furthermore, tight confinement raises the risk of physical injuries and infections such as mastitis, which directly affects milk safety and quality. Cows that lack enough room are more likely to lie in damp or filthy circumstances, increasing the risk of pathogen exposure and milk contamination.

Finally, producers must maintain an ideal group size, ensuring that cows spend less time in holding pens and have easy access to feeding places. Balancing herd size and facility capacity improves cow comfort and productivity, ensuring milk output and quality.

The Unseen Burden: Environmental Stressors Aggravating Dairy Cow Overcrowding

Environmental factors enhance the impact of overpopulation in dairy farms. Poor ventilation may quickly raise ammonia and toxic gasses, aggravating cow respiratory systems and exacerbating illnesses like pneumonia. Inadequate bedding exacerbates this problem, producing comfort issues, foot abnormalities, and increased mastitis rates owing to unsanitary surroundings. Overcrowding often results in restricted availability of food and water, affecting feeding activity and dry matter intake (DMI). Dairy cows need a balanced diet and constant water supply for maximum health and output. Due to limited bunk space, fewer cows can eat the appropriate feed, resulting in decreased DMI, poor body condition, and restricted milk output. This creates a loop in which stressed, undernourished cows are more prone to sickness, lowering herd output. Farmers must manage herd numbers so that each cow has enough room, resources, and comfort. Strategic planning and management are essential for reducing environmental stresses. Addressing these concerns is critical for animal welfare and sustainable dairy production operations.

The Economic Ramifications of Overcrowding in Dairy Farms: A Deep Dive into Profitability and Sustainability

Economic Cost	Description	Estimated Financial Impact
Veterinary Costs	Increased frequency of disease and illness due to stress and inadequate living conditions	$50 – $100 per cow annually
Feed Efficiency	Higher competition for feed leads to inefficient feeding practices and uneven weight gain	5% – 15% increase in feed costs
Milk Yield and Quality	Reduced milk production and quality, leading to lower market prices	2% – 10% drop in revenue
Infrastructure Maintenance	Accelerated wear and tear on facilities due to higher occupancy	$200 – $500 annually
Labor Costs	Increased need for labor to manage overcrowded conditions and stressed animals	Additional $10,000 – $15,000 annually per farm

Overcrowding on dairy farms substantially influences the industry’s profitability beyond just animal welfare concerns. Crowded circumstances increase veterinarian expenditures due to mastitis, lameness, and respiratory problems. These health issues raise veterinarian expenditures and result in continuous costs for chronic illnesses.

Overcrowding has a direct effect on milk output. Stressed cows consume less, resulting in reduced milk output. Studies indicate that adjusting bunk space and group sizes helps sustain milk production levels. For example, moving a herd from one to two groups may boost fat-corrected milk (FCM) by 1% to 3%. Reduced milk production immediately affects the farm’s capacity to satisfy supply obligations, perhaps resulting in financial fines or lost business.

Furthermore, overcrowding may harm a dairy farm’s image in a market where customers increasingly demand ethically produced goods. Farms notorious for poor animal care may lose their competitive advantage, resulting in lower sales and perhaps expensive marketing attempts to improve their public image.

Regulatory Frameworks and Ethical Considerations: The Backbone of Humane Dairy Farming Practices

To address overpopulation in dairy farms, it’s important to consider regulatory frameworks and ethical principles for animal care. Several jurisdictions have enacted regulations to reduce overcrowding and safeguard the health of dairy cattle. These restrictions prioritize humane procedures, including enough space, nourishment, and general animal well-being. The Animal Welfare Act in several nations ensures humane treatment by promoting natural behaviors and well-being. Guidelines frequently specify stocking density limitations to minimize overpopulation. The European Union’s farm animal welfare regulation establishes minimum space requirements and feed and water availability. Organizations like the American Dairy Science Association and the World Organization for Animal Health recommend best practices beyond legal standards, such as providing enough bunk space and reducing pen time. These criteria emphasize the ethical need to balance production and a healthy animal living environment. Noncompliance may result in penalties, license revocation, and reputational harm. Ethical farming techniques prioritize animal care and promote the sustainability and economic viability of the dairy sector.

Proactive Solutions and Best Practices to Address Overcrowding in Dairy Farms

Improved management approaches are critical for addressing dairy farm congestion. Herd size has to be carefully planned, and cow behavior and health must be monitored. Data analytics can identify ideal group sizes based on feeding activity, milk output, and space availability.

Investing in improved housing facilities with enough sleeping space and rest places decreases stress and health problems. Flexible group size, in line with parlor capacity and holding pen time, ensures efficiency and comfort.

Adherence to animal welfare standards, as set by the Animal Welfare Institute and Michigan State University, promotes a compassionate and successful agricultural environment. Meeting these requirements improves cow welfare, farm sustainability, and customer confidence in dairy products.

The Bottom Line

Overcrowding in dairy farming has profound implications that must be addressed immediately. Overcrowding increases stress, health difficulties, and behavioral problems, lowering milk supply and affecting animal welfare and economic returns.

Come along as we dispel misconceptions and provide practical guidance on choosing the best teat dip for your farm. By then, you will be ready to make decisions to safeguard your herd and boost production.

The Role of Teat Dips in Dairy Farming

To protect against infections, teat dips—liquid disinfectants—are applied to dairy cows’ teats before and after milking. These dips, which serve as the first line of defense against mastitis, an inflammatory udder condition, are crucial for dairy farming operations. Their role in reducing the bacteria count on the teat skin not only ensures the production of high-quality milk but also provides a reassuring barrier against illness.

Beyond simple contamination prevention, teat dips are essential for preserving udder health in dairy production. The correct application guarantees uniform coating, forming a barrier against external factors and lowering fissures and sores where germs may flourish. Teat dips can include emollients like glycerin or lanolin to keep the skin flexible and stop dryness and chapping.

Furthermore, teat dips may significantly avoid mastitis, one of the most expensive illnesses in dairy production. Following pre- and post-milking dipping procedures helps farmers improve milk quality while also helping to maintain a low somatic cell count in the milk—an indication of excellent udder health. This monitoring is crucial for securing quality premiums and guaranteeing economic sustainability.

Teat dips are critical for preventing mastitis and enhancing udder health. Farmers can guarantee sound milk output and protect the welfare of their herds by choosing the correct teat dip and consulting milk quality experts.

Debunking the Iodine Myth: Exploring Diverse Germicide Options for Teat Dips

Although most dairy farms believe iodine is the best teat dip germicide, current developments have provided other substitutes with either similar or better effects. For high-yield operations where udder health is critical, chlorhexidine—for example—is hailed for its broad-spectrum antibacterial qualities and long-lasting residual action and known for their efficient cleaning and mildness on teat skin, hydrogen peroxide-based dips shine, especially in challenging weather or with sensitive animals.

Furthermore, lactic and salicylic acids are well-known for their quick action and adaptability in various surroundings. These substitutes challenge iodine’s supremacy and let dairy producers choose the most suitable germicide for their situation, improving udder health and milk quality.

Eventually, the emphasis should be on knowing the many germicides accessible rather than depending only on iodine. This will help dairy producers make wise judgments that guarantee their teat dips fit their particular agricultural environment.

The Synergy Between Germicides and Emollients: Ensuring Comprehensive Teat Health

Any conscientious dairy farmer must realize that a germicide in a teat dip only counts somewhat. Although they destroy microorganisms well, germicides cannot guarantee the cow’s teats’ general protection. Emollients then become necessary.

Emollients assist in preserving and rebuilding the skin’s natural barrier. Varying weather and frequent milking may dry and split teats, increasing their infection susceptibility. Emollients improve cow comfort by keeping the teat skin smooth and less injury-prone, avoiding pathogen entry into the udder.

Formulating a teat dip requires balancing emollients and germicides to improve effectiveness. The proper proportion guarantees that the germicide kills dangerous bacteria without compromising the integrity of the skin. Specific formulas, for instance, have a vivid green hue that ensures coverage and efficacy for apparent assurance of appropriate dipping.

A premium teat dip, made under Good Manufacturing Practices (GMPs), aggregates these elements to provide complete protection. GMPs ensure that the teat dip is produced in a clean and controlled environment, free from contamination. Regular assessment of dipping techniques and full execution of dipping rules help strengthen this protection, improving udder health and producing better-quality milk.

Dispelling the One-Size-Fits-All Myth: Tailoring Teat Dip Formulas to Individual Farm Needs

Many people think that the same teat dip recipes apply everywhere. However, this needs to include the particular requirements of every dairy. Herd size, environmental factors, and specific farm needs vary substantially. A method perfect for a small farm may not work well for a large-scale business. Larger herds could require stronger germicides, whereas smaller farms might concentrate on emollients for improved skin conditions.

Another very vital factor is the weather conditions. While farms in humid climates may need moistening dips to avoid chapping, farms in brutal winters might need fast-drying dips to prevent frostbite. Customizing the teat dip to the particular situation of your farm guarantees good disinfection and enhances teat health.

Think through your farm’s particular requirements. While some might find recipes suited for all-year-round housed herds, others would benefit from colored dips for visual coverage checks. By tackling these many elements, farmers may pick the best teat dip, thus improving udder health, keeping low somatic cell counts, and guaranteeing top-notional milk output.

Strategic Teat Dip Selection: Safeguarding Herd Health and Maximizing Dairy Farm Profitability

Selecting the correct teat dip to protect your herd against mastitis is crucial. Customizing the mixture to fit your farm’s environmental demands guarantees good teat protection and sanitization. In winter, a fast-drying cream decreases chapped teats, lowering infection risk. The complete coating reduces the likelihood of bacteria entering the teat canal by dipping or spraying.

Economically, a good teat dip may result in huge savings. Reasonable mastitis control helps to lower veterinarian expenses and the necessity for culling resulting from ongoing infections. Reduced mastitis instances assist in preserving and improving milk production and quality. Udder health depends on a low somatic cell count (SCC), affecting milk quality and influencing farm profitability, which may attract premium prices. This financial benefit should motivate you to make strategic teat dip selections.

Using items based on good manufacturing standards (GMPs) guarantees consistent performance. Frequent updates to pre- and post-dip treatments support udder health all year round. A local milk quality professional may provide customized advice, achieving a balanced approach to mastitis avoidance, cost savings, and maximum milk output.

The Critical Importance of Choosing the Right Teat Dip: Science and Real-World Evidence

Dairy producers trying to preserve herd health and maintain milk quality must choose the appropriate teat dip. Mastitis may be much reduced using teat dips created based on scientific study. For instance, studies supported by data showed that teat dips significantly reduced mastitis cases and enhanced udder health, lowering somatic cell numbers.

Actual instances confirm this. Six months after changing to a scientifically validated teat dip, a Midwest dairy farm saw mastitis cases decline from 12 to three per month. This action also improved their milk quality premiums, demonstrating the sensible advantages of well-informed judgments.

Certain clinical benefits from using teat dips have been confirmed. Farmers improve herd health and structure their activities to be successful in the long term. See a local hygiene and milk quality professional to identify a proven teat dip catered to your farm’s requirements.

Mastering Dry Cow Management: Essential Strategies for Healthier Cows and Higher Milk Yields

Tuesday, July 2nd, 2024

Master dry cow management for healthier bovines and higher milk yields. Discover essential strategies to optimize udder recovery and nutritional status. Ready to improve?

Do you think the dry period is a carefree vacation for dairy cows? Think again. Dry cow management is often underestimated, yet it’s pivotal for your herd’s productivity. This phase is essential for ensuring optimal cow health and maximizing milk yields in the subsequent lactation cycle.

Underestimating the importance of dry cow management can reduce milk production, cause metabolic diseases, and result in poor fertility. It’s a misconception that dry cows require minimal attention. Strategic planning and meticulous care are crucial to prepare the udder for future milk production and stabilize the cow’s nutritional status to prevent health issues. Neglecting effective dry cow management is not an option.

Unlocking the Potential of Dry Cow Management: Objectives and Strategies

A pivotal aspect of dry cow management is recognizing the primary objectives of this period. The primary goal of the dry period is to let the udder recover from the previous lactation, which is essential for maintaining udder health and optimizing milk production in the next cycle.

Additionally, this period prepares the cow for the upcoming lactation. Ensuring optimal nutritional status is critical to supporting this transition and reducing the risk of metabolic diseases and reproductive issues post-calving.

This involves more than dietary adjustments—it requires an integrated approach. Monitoring body condition scores, managing feed space, employing strategies like trace minerals, and adjusting dietary cation-anion balance (DCAB) are all crucial. These measures aim to prevent health issues like hypocalcemia and ensure a smooth transition into the next lactation, maintaining farm productivity and animal wellbeing.

Understanding the Imperative of Drying Off: Risks and Rewards

Drying off cows poses significant challenges, primarily the risk of mastitis due to milk accumulation and udder inflammation. When milking stops abruptly, milk builds up, putting pressure on the udder and creating an entry point for bacteria, leading to discomfort and infections.

Despite these risks, drying off is essential for the cow’s well-being and productivity. Without a dry period, cows face reduced future milk production, over-conditioning, and poor fertility. Thus, the drying-off process remains crucial for the long-term health and productivity of the herd.

Strategic Planning for Seamless Transition: Optimal Dry Period Management

Effective dry period management is not just a break from milking but a critical period that influences the future health and productivity of the dairy cow. With strategic planning and proper nutrition, you have the power to ensure optimal outcomes.

A structured approach involves maintaining a dry period of 40 to 60 days. Deviating from this range can lead to issues like poor udder health, reduced milk yield, or over-conditioning, which can cause metabolic disorders such as ketosis.

Nutritional strategies are vital. Tailored diets for the early and late stages of the dry period help cows maintain optimal body condition and prepare for the demands of lactation. The far-off and close-up diets adjust energy levels to prevent problems like hypocalcemia, demonstrating the importance of focused nutritional management.

In conclusion, the dry period is a cornerstone of dairy cow health management. Diligent and informed management during this time is critical for recovery and preparation for the next lactation cycle, leading to better milk production, improved fertility, and overall herd health.

Evidence-Based Optimal Dry Period Length: Achieving the Balancing Act of Udder Health and Milk Yield

Research consistently supports a dry period length of 40-60 days for dairy cows to ensure udder recovery and preparation for the next lactation. Shorter dry periods can lead to mastitis and reduced milk yields due to insufficient time for mammary gland regeneration. Conversely, longer dry periods often result in over-conditioning, predisposing cows to metabolic disorders like ketosis and fatty liver. This condition exacerbates inflammation during the transition, harming overall cow health and performance. Adhering to the recommended dry period length is crucial for maximizing udder health and optimizing milk production in dairy herds.

Mastering Nutritional Management: Crafting Optimal Diets for the Dry Period

As we delve into nutritional management during the dry period, we recognize the significance of tailored dietary strategies, which are crucial to supporting cow health and productivity. Recommended approaches involve a bifurcated diet plan: the far-off and close-up diets.

During the first five weeks, the far-off diet features low energy density to maintain but not increase body condition. Anecdotal evidence and research suggest that managing energy intake helps prevent over-conditioning, a precursor to metabolic diseases.

In the last three weeks, the close-up diet, with moderate energy density, has sustained body condition and ensured rumen health for the upcoming lactation period. Additionally, preventing hypocalcemia by adjusting dietary minerals or adding anionic salts is crucial.

Large farms can manage two distinct diet groups, allowing precision feeding, a practice that tailors feed rations to individual cow needs, and better control over nutritional intake. Smaller farms, however, may benefit from a single diet that balances the far-off and close-up needs due to space and animal number constraints. While less specific, this method avoids logistical and labor issues for multiple feeding regimens.

Effective feed bunk management and 30 inches of bunk space per cow can alleviate space and feeding behavior challenges. Additionally, novel approaches like using late-maturing crops or planting later can help reduce feed energy content, easing the dietary balance during the dry period.

Ensuring Balance and Health: The Far-Off Diet Phase for Optimal Dry Cow Management

The far-off diet phase, covering the initial five weeks of the dry period, focuses on maintaining the cow’s body condition without excessive weight gain. This period allows the cow to rest and recover after lactation. Thus, the diet is low energy density, balancing nutritional needs and minimizing the risk of metabolic disorders like ketosis in the subsequent lactation.

This diet includes fibrous components such as hay and pasture, with minimal concentrates to avoid high starch and energy levels. Maintaining a body condition score of 3.0 to 3.5 on the 5-point scale, which assesses the cow’s fat reserves and muscle tone, is crucial for a smooth transition into the close-up period, where diet adjustments happen for calving and lactation.

Farmers manage the cow’s energy balance through a controlled, low-energy diet, supporting her health and productivity. Proper feed bunk management ensures each cow has sufficient access to feed and can eat comfortably, enhancing intake and well-being. This phase is critical for successfully transitioning to the next production cycle, highlighting the importance of strategic nutritional planning during the far-off period.

Navigating the Final Stretch: Crafting the Ideal Close-Up Diet for Dry Cows

The close-up diet is pivotal in preparing cows to shift from dry to lactating. Administered during the final three weeks, it features a moderate-energy density mix to maintain body condition and prime rumen health. Key elements include adequate fiber and a balanced grain-to-forage ratio, which prevent digestive issues and ensure consistent feed intake.

Preventing hypocalcemia (milk fever) is paramount. Strategies include manipulating Dietary cation-ion balance (DCAB) with anionic salts to mobilize calcium from bones and boost blood calcium at calving. Managing mineral intake by reducing calcium and supplying trace minerals like magnesium and phosphorus is crucial for calcium metabolism and bone health.

Optimal feed bunk management, sufficient space, and a clean, stress-free environment further ensure a smooth transition. The close-up diet is not just nutritional; it’s an integral management strategy for safeguarding cow health and maximizing future productivity.

The Bedrock of Successful Dry Cow Management: Vigilant Body Condition Score (BCS) Monitoring

One of the most critical aspects of dry cow management is vigilant body condition score (BCS) monitoring. The ideal BCS for dry cows lies between 3.0 and 3.5 on the 5-point scale. This range is crucial for cow health, smooth transitions into lactation, and enhanced reproductive performance.

Monitoring BCS during the dry period allows timely adjustments in nutritional strategies, preventing metabolic diseases and promoting high-quality milk production. Over-conditioned cows, scoring above 3.5, face higher risks for conditions like ketosis and fatty liver, which can hinder productivity and fertility.

Achieving and maintaining an ideal BCS is often complicated by high-starch feeds available in various regions. This necessitates a tailored approach to diet formulation and constant adjustments based on cow condition and feed quality.

Ultimately, effective BCS monitoring and management are vital. Maintaining an optimal BCS ensures smooth lactation transitions, higher-quality milk, and fewer calving issues, boosting farm performance and profitability.

Maintaining an Optimal Body Condition Score (BCS): A Cornerstone for Dairy Cow Health and Farm Profitability

Maintaining an optimal Body Condition Score (BCS) is crucial for dairy cow health, milk production, and reproductive performance. Research shows that cows with a BCS of 3.0 to 3.5 during the dry period produce higher-quality milk and have better reproductive efficiency, including entering estrus sooner and having higher conception rates. These cows also experience smoother calving and healthier calves.

Over-conditioned cows, however, face significant risks, such as metabolic diseases like ketosis and fatty liver, leading to systemic inflammation. This hampers milk yield and triggers health complications. Elevated BCS increases fat mobilization during early lactation, worsening metabolic disorders and leading to poorer fertility and slower recovery post-calving.

Vigilant BCS monitoring and tailored nutrition are essential. Farm managers can reduce health risks, improve reproductive outcomes, and boost profitability by maintaining an optimal BCS. Adequate diet and management during the dry period are critical to a successful lactation phase.

Targeted Care for Vulnerable Groups: Over-Conditioned, Nulliparous, and Calving Disorder Cows

High-priority cow groups include over-conditioned cows, first-calf (nulliparous) cows, and those with calving disorders such as dystocia, stillbirths, twins, and retained placenta. These cows face elevated risks due to heightened systemic inflammation during the transition period, increasing their likelihood of disease and poor performance.

Over-conditioned cows often suffer from metabolic issues like ketosis and fatty liver, affecting their health and productivity. First-calf cows, dealing with the demands of their initial lactation, are more prone to inflammation, impacting their overall health and future fertility. Similarly, cows with calving disorders face stress and inflammation from abnormal births, making them susceptible to infections and slower recoveries. Properly managing these high-priority groups is crucial to minimize risks and ensure a smooth transition to lactation.

Pioneering Anti-Inflammatory Strategies: Enhancing Health and Performance Through Innovative Dry-Off Management

Recognizing the importance of managing inflammation during the dry-off period, our research has focused on innovative strategies to enhance cow health and transition success. A promising approach under study involves applying anti-inflammatory treatments at dry-off for over-conditioned cows. This strategy aims to reduce the systemic inflammation often seen during the transition period. By curbing inflammation, we hope to ensure a smoother shift to the next lactation, lowering health risks and boosting performance. Early trial results are promising, indicating that such interventions could be crucial for maintaining cow wellbeing and farm profitability.

Integrating Holistic Management: A Multifaceted Approach to Dry Cow Care

Effective dry cow management begins well before the dry-off phase and requires a holistic approach. This strategy includes nutritional management to provide the right blend of nutrients tailored to the cows’ needs. By carefully adjusting the dry period length, we can avoid over-conditioning and related metabolic disorders, protecting both udder health and future milk yields.

Body condition score (BCS) monitoring is crucial for timely interventions to keep cows healthy. Addressing the needs of high-priority groups, like over-conditioned cows and those with calving disorders, ensures targeted care, reduces systemic inflammation, and boosts overall performance.

Innovative treatments, such as selective anti-inflammatory protocols at dry-off, can significantly reduce inflammation and stress during the transition. These strategies ensure a smooth shift from gestation to lactation, improving reproductive outcomes and milk quality.

Adopting this multifaceted approach helps dairy farmers keep their cows healthy and maximize production potential. Holistic dry cow management is essential for sustainable dairy farming, promoting animal welfare and farm profitability.

Long-Term Impact of Heat Stress on Dairy Cattle: Beyond Milk Production to Fetal Health and Farm Sustainability

Thursday, June 20th, 2024

Explore how heat stress affects dairy cattle in more ways than just reducing milk production. Understand its impact on unborn calves and the overall health of the farm. How can we reduce these risks?

Heat stress has long-term effects that are more severe as temperatures increase. Heat stress is more than just a nuisance in the dairy business; it also seriously affects other aspects of operations beyond milk production. In the United States, annual losses from heat-stressed dry cows top $1.5 billion; the broader consequences damage immunological function, reproductive health, and fetal development, jeopardizing the viability of dairy businesses.

Although heat stress affects milk output, its effect on fetal growth compromises future resilience and output. Not just financially but also ethically, reducing heat stress during the dry months guarantees the health and sustainability of successive generations of dairy cows.

The Multifaceted Economic Toll of Heat Stress in Dairy Farming

Category	Economic Impact (Annual)
Milk Production Loss	$900 million
Reproductive Health	$320 million
Fetal Development	$190 million
Immune Function	$100 million
Other Related Losses	$50 million
Total Economic Impact	$1.56 billion

Heat stress’s financial effects on the dairy sector go well beyond the acute drop in milk output. Although the startling $1.5 billion yearly loss in the United States resulting from dry cows is noteworthy, it only addresses dairy farmers’ more general financial difficulties. Heat stress reduces reproductive efficiency, which lowers conception rates and increases calving intervals, therefore lowering the herd’s total production and profitability. Furthermore, decreased fetal development produces smaller calves with reduced birth weights, which increases veterinarian expenses and raises death rates.

Furthermore, heat-stressed cows’ compromised immune systems increase their vulnerability to illnesses such as mastitis, which calls for more frequent medical visits and increases treatment expenses. These health problems cause immediate costs and shorten the afflicted animals’ lifetime and output, therefore aggravating the economic load. The reduced capacity of heat-stressed cows to realize their genetic potential results in a long-term financial load as farmers have to spend more on maintaining herd health and performance.

Moreover, heat stress’s knock-on effects might upset the whole supply chain. Reduced milk supply reduces dairy products’ availability, influencing market stability and possibly pushing up costs. The combined influence of these elements emphasizes the crucial need to implement sensible heat-reducing techniques. Farmers may protect their financial interests by prioritizing their herd’s well-being, guaranteeing their activities’ continued profitability and sustainability.

Heat Stress in Dairy Cattle: Undermining Reproductive Health and Fetal Development

Heat stress disrupts endocrine processes and compromises reproductive cycles, seriously affecting the reproductive health of dairy cows. Increased temperatures disrupt hormonal signals vital for ovulation, lowering conception rates and compromising effective fertilization and embryo implantation.

Heat stress also reduces udder growth, therefore reducing milk output and quality. Excessive heat changes blood flow and nutritional availability to udder tissues, reducing milk output and aggravating the financial losses experienced by dairy companies.

Heat stress also affects prenatal development; stressed cows often have smaller calves with compromised organ development. These long-term effects emphasize how urgently efficient heat-reducing techniques are needed to guarantee the health and survival of future generations within the herd.

Insidious Impacts of Heat Stress During Late Gestation: A Threat to Future Herd Productivity

Heat stress badly affects fetal growth in the latter trimester of pregnancy. This period is absolutely necessary for fast development and essential organ development. Reduced uteroplacental blood flow during mother heat stress causes smaller nutrition and oxygen availability, which lowers birth weights and organs. These shortcomings affect development long-term.

Less functioning and smaller immune organs, such as the thymus and spleen, increase the calf’s illness susceptibility. Besides, poor thermoregulation causes the calf to struggle with temperature fluctuations throughout its life. These problems stop the calf from realizing its full genetic potential by hindering its development and output.

Every incidence of slowed-down fetal development influences the future output of the herd. Over time, this results in lower milk output, more veterinary expenses, and higher morbidity and death rates. Therefore, farm sustainability is in jeopardy as the residual effects of heat stress progressively compromise the economic viability of dairy enterprises.

Maternal Heat Stress: A Silent Saboteur of Calf Immunity and Long-Term Viability

Maternal heat stress during pregnancy has far-reaching effects, especially on the immune system of unborn calves. Higher prenatal temperatures impair the growing immune system, increasing susceptibility throughout life. The first significant checkpoint for a newborn’s immune system is the absorption of antibodies from colostrum, the first milk post-parturition. Heat-stressed moms generate infants with a much-reduced capacity to absorb these essential antibodies, which compromises start and raises vulnerability to illnesses. Reduced functioning from the beginning and weakened immune organs like the thymus and spleen aggravate the young animal’s difficulty in building strong immunological responses. These early difficulties constantly hinder reaching full genetic potential and contribute to farm success by endangering immediate survival and interfering with long-term health and output.

A Detrimental Cascade: Heat Stress and its Consequences on Fetal Growth and Immunological Development

Heat stress seriously alters the fetal nutrition supply, which results in undeveloped organs and reduced birthweights. Restricted blood flow to the uterus and placenta reduces the fetus’s supply of nutrients and oxygen. This deficiency reduces fetal development, producing smaller babies with reduced organ function.

The effect on immunological organs such as the thymus and spleen is particularly worrying. Crucially part of the immune system, these organs are sometimes smaller in calves born from heat-stressed cows. Important for T-cell generation, the thymus, and the spleen—key for blood filtration and building immunological responses—are compromised, reducing the calf’s lifetime capacity to fight infections. This compromised immune system increases disease sensitivity and reduces long-term health and productivity.

The Vicious Cycle of Heat Stress: Impaired Thermoregulation and its Lifelong Consequences

A calf’s capacity to control its body temperature is seriously disrupted by maternal heat stress, a result of which embryonic development of the hypothalamic-pituitary-adrenal (HPA) axis suffers. Rising prenatal temperatures impede this vital mechanism, which causes lifetime thermoregulation problems. Born from heat-stressed moms, calves often suffer from chronic conditions, including overheating, poor feed intake, and slowed development rates. As these animals lose their ability to control environmental stresses, their immediate survival post-birth and long-term production is threatened, jeopardizing their general health and farm performance.

From Economic Strategy to Moral Imperative: Addressing Heat Stress During the Dry Period in Dairy Farming

Dealing with heat stress during dry times goes beyond just financial need; it is a great moral and financial need for the dairy business. Heat stress disrupts more than instantaneous milk production deficits. Among them are problems with reproductive health, poor fetal development, and decreased immune system—a whole costly load cascade. Ignoring these problems compromises not just present profitability but also sustainable dairy production.

Our obligations go beyond money. We must ensure dairy cattle are healthy, well-adjusted, and future-productive as their caregivers. During vital times like gestation and the dry phase, heat stress compromises the potential of future generations. It increases their susceptibility to ongoing health problems and lowers viability. By giving techniques to fight heat stress first priority, we protect our financial interests and maintain moral standards, thus assuring that dairy cattle flourish for the next generations.

The need—moral as much as financial—to reduce heat stress drives us to put strong plans into action. These steps may guarantee the lifetime, output, and resilience of dairy herds, thereby fostering sustainability and moral responsibility for future generations.

The Bottom Line

Deeply affecting dairy cows, heat stress affects not only milk output but also the immune system, reproductive health, and foetus development. These consequences compromise the herd’s future output and the financial feasibility of dairy farms. Reducing heat stress, particularly during the dry months, is crucial for protecting fetus health and guaranteeing the resilience of dairy farming businesses.

The long-term success of a farm depends on investments in calf health. Meeting Youngstock’s requirements will help them resist heat stress, avoid immunological problems, and increase the farm’s profitability and sustainability. Our moral and financial obligations are to give the wellbeing well-being of the next generation the first priority.

Dairy producers must implement sensible heat stress-reducing plans. These include maximizing barn conditions, guaranteeing enough water, and using technology to lower heat exposure. These actions will help us preserve our herds, increase output, and advance environmentally friendly dairy production for future generations.

Key Takeaways:

Heat stress disrupts normal udder development, impeding milk production directly.

Understanding Ketones and Ketosis: Boosting Dairy Cow Health and Productivity

Wednesday, June 19th, 2024

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

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

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

The Vital Role of Ketones in Dairy Cow Lactation

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

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

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

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

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

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

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

Ketosis and Milk Production: Unraveling the Economic and Biological Complexities

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

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

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

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

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

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

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

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

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

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

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

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

Revolutionizing Dairy Health: The Hidden Benefits of Ketones

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

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

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

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

Ketoacidosis Prevention: Practical Tips for Dairy Farmers

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

Teat Sealant Residue: What Farmers Need to Know for Healthier Udders and Smoother Milking

Monday, June 17th, 2024

Discover how teat sealant excretion post-calving impacts udder health and ease of milking. Are you optimizing your dairy cow treatment for better results?

For dairy producers, maintaining ideal udder health is vital. A healthy udder leads to higher milk outputs, excellent cow health, lower vet expenses, and constant milk quality. Still, elements like mastitis may compromise udder condition. As we strive to reduce antibiotic usage in cattle, herd management techniques are evolving. Selective dry cow treatment programs are gaining prominence, a superior alternative to blanket dry cow treatments with antibiotics. Based on the cow’s somatic cell count (SCC), these programs utilize internal teat sealants (TS) either with antibiotics or alone. This approach, in line with antibiotic stewardship guidelines, reduces antibiotic consumption and helps maintain udder health, leading to improved milk quality.

Are you seeking to improve the effectiveness of your dairy farm? Discover fresh ideas and keep ahead in environmentally friendly dairy farming.

Revolutionizing Dry Period Management: The Role of Selective Dry Cow Treatment (SDCT) in Modern Dairy Farming

Maintaining udder health throughout the dry period—when a dairy cow is not lactating—is vital in the dairy business. This time frame helps prevent diseases that can compromise the health of the herd or a cow’s output. Mastitis was historically prevented by antibiotics during drying out (DO). However, more rigid EU rules and issues with antibiotic resistance have resulted in selected dry cow treatment methods (SDCT).

SDCT uses internal teat sealants (TS) alone or with antibiotics based on individual cow infection risks:

1. High Somatic Cell Count (H-SCC) Cows: Cows with high somatic cell counts (SCC) are prone to infections and are treated with both antibiotics and TS (H-ABTS). Antibiotics treat existing infections, while TS prevents new ones.

2. Low Somatic Cell Count (L-SCC) Cows: Cows with low SCC, at lower infection risk, receive TS only (L-TS), providing a barrier against pathogens without using antibiotics.

This method guarantees that high-risk cows receive the required therapy and helps reduce antibiotic consumption. However, its success relies heavily on the vigilance of dairy producers and veterinarians in monitoring SCC levels and udder health. By emphasizing their integral role in optimizing SDCT procedures, dairy producers can feel more involved and committed to maintaining udder health.

Unveiling the Secrets of Teat Sealant Excretion: A Comparative Study of High and Low SCC Dairy Cows Post-Calving

Aiming to expose how internal teat sealants (TS) are expelled after calving and their effect on udder health and milking equipment cleanliness, the research Postpartum excretion of internal teat sealant following selected dry cow treatment of dairy cows intended compared TS excretion in low SCC cows treated alone with TS to TS in high somatic cell count (SCC) cows treated with antibiotics. It also measured how well lab staff members and farmers could find TS residues after milking and calving.

The approach was meticulously crafted for consistent understanding. The research included four German herds and 192 cows from Dutch herds three-wise. While low SCC cows (L-TS, n=99) were treated with TS alone, high SCC cows (H-ABTS, n=93) were given antibiotics and TS.

They collected 50 mL pre-milk samples from every udder quarter during the first 15–16 milkings after calving. This technique permitted a thorough study of T’s visibility, amount, and excretion patterns during the first milkings.

Decoding the Visibility of Teat Sealant Residues in Pre-Milk: Insights from Farmers and Laboratories

Milkings Post-Calving	H-ABTS TS Excretion (%)	L-TS TS Excretion (%)
First Milking	32%	45.5%
Second Milking	8.5%	4.6%
Third Milking	1.8%	0.4%

One of the most critical research results is pre-milk teat sealant (TS) residue visibility. Lab staff members and farmers reported TS residue in 72% of quarters during the first milking post-calving. This notable incidence of detection emphasizes the ubiquitous existence of TS residues in the early postpartum period. It also underscores the necessity of careful surveillance and control, making dairy producers feel responsible and proactive in maintaining udder health and milk quality.

The research initially revealed the farmers’ remarkable sensitivity in spotting teat sealant (TS) residues. In 74.5% of the instances, producers found TS remains during the first milking. However, this capacity experienced an apparent fall during the next three milkings, falling to only 8.3% by the final three milkings. This notable decline emphasizes the difficulties and possible discrepancies in identifying TS residues without expert knowledge or a laboratory environment.

The next milkings clearly showed a change in discharge patterns. Compared to cows in the L-TS group (4.6%), cows in the H-ABTS category showed a greater mean adjusted TS percentage excretion (8.5%) during the second milking. H-ABTS cows showed 1.8% TS excretion. In contrast, L-TS cows showed much lower excretion levels at a 0.4% trend until the third milking. This result implies a clear difference in the pace and persistence of TS excretion between the two groups, suggesting that treatment type and somatic cell count category play significant roles in the post-calving excretion dynamics.

The multivariable model outputs identified essential variables affecting the occurrence of teat sealant (TS) residues in the first three milkings. Especially during the first and second milkings, parity became a significant factor, indicating that multiparous cows were more prone to show TS residues. Furthermore, the research group was strongly linked to T’s presence at the second and third milkings, suggesting that the type of cows—whether treated with antibiotics + TS or TS alone—also greatly affected the appearance and excretion patterns of TS post-calving.

Fascinatingly, the univariable model looking at udder health found no correlation between udder health outcomes and teat sealant (TS) residue present during the first milking. This implies that the general state of the cow’s udder is not immediately affected by the first appearance of TS, which is a crucial realization for farmers considering the advantages and drawbacks of TS application.

Empowering Dairy Farmers: Strategic Insights for Managing Teat Sealant Use and Maintaining Udder Health

Understanding the post-calving teat sealant (TS) excretion for dairy producers is critical to refining their selected dry cow treatment (SDCT) strategies. The fact that TS residues are most noticeable during the first milking post-calving is a crucial insight. This knowledge helps farmers plan to prevent contamination of milking equipment and anticipate cleaning difficulties, thereby maintaining udder health and milk quality. The need for customized hygiene measures is underscored by the increased TS excretion observed in cows treated simply with TS (L-TS) compared to those treated with antibiotics plus TS (H-ABTS).

Farmers may teach employees to recognize and handle TS wastes, particularly in first milkings when residue visibility is maximum. The research indicates that the difference in residue detection between farms and labs closes with time, implying the advantage of rigorous early monitoring followed by consistent but less frequent inspections. Farmers that follow these guidelines may safeguard udder health and follow the rules on antibiotic restrictions, improving animal welfare and milk quality.

The lack of a clear correlation between TS residue presence at the first milking and udder health confirms that well-controlled TS use does not jeopardize the dairy herd’s health. Optimizing SDCT procedures depends on proper training and equipping farm staff to control TS wastes; so, balancing efficient udder health management and operational effectiveness also depends on this.

The Bottom Line

With an eye on post-calving milking practices, the research emphasizes essential aspects of teat sealant (TS) excretion in dairy cows. Significant results reveal a clear bimodal excretion pattern wherein TS remains are more evident during the first milking. Although their udder health was not much affected, L-TS cows had a greater TS excretion rate (45.5%) at the first milking than H-ABTS cows (32%).

These revelations stress farmers’ need to carefully clean milking equipment to prevent residue development. Farmers can identify TS residues well during the first milking, yet their capacity declines in later milkings. This implies that better training or procedural modifications are needed to maintain milk cleanliness.

Knowing that T’s presence does not compromise udder health lets farmers boldly follow chosen dry cow treatment guidelines. This approach guarantees udder health and farm output by supporting effective herd management and antibiotic reduction policies.

Key Takeaways:

Internal teat sealants (TS) are being increasingly used in European dairy farms to comply with antibiotic restriction policies and maintain udder health.
Post-calving TS residues can attach to milking equipment, making cleaning difficult and deterring some farmers from using TS across all cows.
A study across herds in the Netherlands and Germany compared TS excretion in high SCC cows treated with antibiotics and TS (H-ABTS) versus low SCC cows treated with TS only (L-TS).
TS residues were visible in 72% of quarters during the first milking, with farmer sensitivity to spot TS dropping significantly after the first milking.
The study found a higher percentage of TS excretion in low SCC cows (L-TS) at the first milking compared to high SCC cows (H-ABTS).
TS excretion quantities exhibited a bimodal pattern, with greater excretion in multiparous cows and no link to udder health issues at the first milking.
Effective management of TS excretion can empower dairy farmers to optimize udder health and enhance milk quality while adhering to antibiotic restrictions.

Summary: Dairy producers need to maintain optimal udder health for higher milk outputs, good cow health, lower vet expenses, and consistent milk quality. Selective dry cow treatment programs (SDCT) are gaining popularity as an alternative to blanket dry cow treatments with antibiotics. These programs, based on the cow’s somatic cell count (SCC), use internal teat sealants (TS) with or without antibiotics. This approach reduces antibiotic consumption and improves milk quality. The success of SDCT relies on the vigilance of dairy producers and veterinarians in monitoring SCC levels and udder health. A study of high and low SCC dairy cows post-calving revealed how internal teat sealants (TS) are expelled and their effect on udder health and milking equipment cleanliness. Customized hygiene measures are necessary, as cows treated with TS had increased TS excretion compared to those treated with antibiotics plus TS. Farmers can teach employees to recognize and handle TS wastes, especially in first milkings. Following these guidelines can safeguard udder health and improve animal welfare and milk quality.

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

Friday, June 14th, 2024

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.

Ovarian Cysts	4	0.8	0.53	0.32
Paratuberculosis	4	0.8	0.53	0.32
Retained Placenta	3	0.6	0.4	0.25

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.

Uncover the potential of basil and bergamot essential oils as natural remedies for dairy cattle mastitis. Can these powerful oils offer a formidable defense against the rising challenge of antibiotic resistance?

Mastitis is a significant issue in dairy farming, affecting the cows’ health and the economic value of milk production. This inflammation of the mammary gland harms the cows. It lowers the quality and quantity of milk, leading to significant financial losses for farmers worldwide. The traditional use of antibiotics is under scrutiny because antibiotic-resistant bacteria are making treatments less effective and posing severe public health risks. Because of this, there is an urgent need to explore natural remedies that can manage and prevent mastitis without adding to the problem of antibiotic resistance.

“Relying on antibiotics to treat mastitis is no longer sustainable. We need to turn to natural solutions to protect our dairy herds and ensure the purity of our milk.”

Essential oils like basil and bergamot are showing promise in the fight against mastitis. These natural extracts have strong antibacterial properties that target the bacteria causing mastitis without leaving harmful residues in milk or the environment. Exploring essential oils could help reduce the spread of antibiotic-resistant bacteria and support a more sustainable approach to dairy farming. It is crucial to investigate these natural solutions further to change how we treat mastitis and secure the future of dairy production.

For dairy farmers grappling with the dual challenges of antibiotic resistance and the demand for cleaner, healthier milk, this article unveils essential oil solutions that promise to revolutionize mastitis treatment and foster sustainable dairy farming.

Understanding Mastitis in Dairy Cattle

Mastitis, the most common disease in dairy cattle worldwide, causes significant economic losses and challenges the dairy industry. The inflammation of the mammary gland parenchyma due to physical trauma or infections affects the milk’s quality and makes it unsuitable for use.

There are three types of mastitis: clinical, sub-clinical, and chronic. Clinical mastitis is easy to spot with signs like abnormal milk, swelling or tenderness of the udder, and symptoms like fever and loss of appetite. Farmers can usually diagnose it quickly due to visible signs.

Sub-clinical mastitis is more complicated to detect because it lacks apparent symptoms. It can go unnoticed but slowly reduces milk yield and alters its composition, affecting the profitability of dairy farms.

Chronic mastitis is a long-term infection with periods of remission and flare-ups. It can cause lasting damage to the mammary tissue, making disease management and herd health more difficult.

Mastitis affects milk production and requires strict treatment protocols. While antibiotics have been used traditionally, concerns about antibiotic resistance and drug residues in milk have led to interest in alternative treatments. Essential oils are one such alternative being explored. They are derived from plants and have shown promising results in treating mastitis. As we continue to study and refine their use, essential oils could become a sustainable and effective option for treating mastitis.

Cost Component	Economic Impact (per cow/year)
Reduced Milk Production	$100 – $300
Veterinary Treatment	$50 – $150
Labor Costs	$30 – $70
Discarded Milk	$20 – $50
Replacement Costs	$150 – $350
Miscellaneous Costs	$10 – $20
Total Economic Impact	$360 – $940

The Growing Problem of Antibiotic Resistance in Dairy Farming

The frequent and careless use of antibiotics in dairy farming has led to antibiotic-resistant bacteria. This resistance makes infections like bovine mastitis, caused by Staphylococcus aureus and Escherichia coli, more challenging to treat. As a result, there’s a higher risk of antibiotic residues in milk.

Milk with antibiotic residues can cause allergic reactions and disturb the human gut microbiota, leading to long-term health issues. It also contributes to antimicrobial resistance (AMR), allowing bacteria to share their resistant traits and making infections more challenging to treat.

According to recent data, nearly 70% of mastitis-causing bacteria have resisted common antibiotics, highlighting the necessity for alternative treatments in dairy farming. This alarming statistic underscores the urgency of shifting towards more sustainable and effective methods.

Given these challenges, the reliance on antibiotics could be more sustainable. The agricultural sector , including dairy farmers, veterinarians, and industry stakeholders, needs alternatives that effectively manage bovine mastitis without worsening AMR. By exploring and adopting natural solutions like essential oils, you can help reduce the risks connected with antibiotic use and meet the growing demand for natural, residue-free dairy products, empowering you to be a part of this important transition.

Why Choose Natural Remedies for Mastitis?

The move towards natural remedies like essential oils (EOs) such as basil and bergamot addresses the limitations of traditional treatments. These oils are extracted from the plants through a process of steam distillation or cold pressing, preserving their natural properties. Firstly, the issue of antibiotic resistance is significant. Dairy farming often uses antibiotics like penicillin, ampicillin, tetracycline, and gentamicin, administered through infusions or injections. Over time, pathogens become resistant, reducing the effectiveness of these drugs and pushing farmers to look for alternatives.

Antibiotic residues in milk are another primary concern. These residues pose health risks to humans and affect the safety and quality of dairy products. With consumer awareness growing, the demand for residue-free, organic milk is increasing, urging the industry to find sustainable solutions.

Alternative treatments like essential oils are also important from an economic viewpoint. Traditional antibiotics not only contribute to resistance but also come with high costs. In contrast, essential oils from plants offer a cost-effective and environmentally friendly option. The initial investment in essential oils may be higher, but their long-term use can lead to significant cost savings, making them practical for dairy farming.

Moreover, extensive research supports the safety and effectiveness of essential oils against mastitis-causing pathogens. Studies have consistently shown that basil and bergamot essential oils can inhibit the growth of these pathogens, providing a solid foundation for their use in mastitis treatment. This reassurance should instill a sense of confidence and trust in the potential of these natural remedies.

Despite essential oils’ promise, more clinical trials are needed. These trials will help us understand the potential long-term effects of essential oils and any potential challenges or limitations they may have. Research and standardization of EO application methods are crucial to understanding their full potential and establishing reliable guidelines for their use in veterinary practice. Nevertheless, the initial findings are promising, indicating a shift towards more sustainable and health-conscious approaches in dairy farming.

How Essential Oils Reduce Antibiotic Resistance

Essential oils are a promising alternative to antibiotics because they work in various ways. Unlike antibiotics that usually target one bacterial function, essential oils like basil and bergamot contain multiple active compounds that disrupt different bacterial functions. This makes it harder for bacteria to develop resistance.

Essential oils help fight antibiotic resistance by inhibiting efflux pumps in bacterial cells. These pumps typically expel antibiotics, but essential oils block them, allowing the antimicrobial agents to work effectively. Essential oils also have compounds like terpene hydrocarbons that are strong against pathogens causing mastitis.

The diverse chemical makeup of essential oils attacks bacterial cell walls, membranes, and even internal processes like DNA replication and protein synthesis. For example, basil oil disrupts bacterial membranes, causing cell leakage and death. Bergamot oil interferes with bacterial enzymes, disrupting critical metabolic processes.

Essential oils offer additional benefits by reducing the overall use of antibiotics. By providing an effective alternative treatment for mastitis, essential oils can help reduce the frequency and dosage of antibiotic use, which lowers the risk of developing resistant bacteria. They also break down more quickly in the environment than synthetic antibiotics, reducing the ecological impact on soil and water.

Using essential oils to treat dairy cattle mastitis marks a significant shift towards sustainable veterinary practices. Essential oils reduce the development of antibiotic-resistant bacteria and minimize antimicrobial residues in milk and the environment. This not only improves animal welfare but also ensures the production of safer dairy products. As we learn more about their uses and refine their application, essential oils could become crucial to animal husbandry’s future.

The Antibacterial Properties of Basil Oil

Basil essential oil has numerous benefits in treating mastitis. It offers both antimicrobial and anti-inflammatory properties. Its antibacterial properties effectively target and inhibit the growth of bacteria that cause mastitis. This effect comes from eugenol and linalool, which disrupt bacterial cell membranes and metabolic processes.

Additionally, basil essential oil has anti-inflammatory effects on inflamed udders, reducing swelling and redness associated with mastitis. By calming the body’s inflammatory response, basil oil not only eases discomfort but also speeds up the healing of healthy tissue. This dual action of lowering bacterial load and reducing inflammation helps cattle recover faster.

Moreover, basil oil is safe for use in dairy farming. Unlike antibiotics, which can leave harmful residues in milk and promote antibiotic resistance, basil essential oil is a natural remedy with no side effects. This safety profile supports sustainable farming practices and meets the growing consumer demand for dairy products free from synthetic additives. Thus, using basil essential oil in mastitis treatment improves cattle health and supports public health and environmental goals.

Bergamot Essential Oil: A Potent Mastitis Fighter

Bergamot essential oil is effective against pathogens like Staphylococcus aureus and Escherichia coli, often resistant to traditional antibiotics. Compounds in bergamot oil, such as limonene and linalool, help fight these tough bacteria.

Using bergamot oil in mastitis treatment can improve dairy production. It reduces infection rates, enhances udder health, and boosts milk yield and quality. Healthier udders mean better lactation cycles, benefiting the cows and the farmers economically.

Bergamot oil also soothes and heals damaged udders. Its anti-inflammatory properties reduce swelling and pain, helping the udders heal faster. This natural remedy alleviates the distress mastitis causes in dairy cows, promoting their overall health and productivity.

Integrating Essential Oils into Dairy Farming Practices

Integrating essential oils into dairy farming must consider both practical and economic aspects. Firstly, dairy farmers need education on proper use and dosage to ensure effectiveness and avoid adverse effects. Training programs can provide farmers with hands-on experience and knowledge.

It is essential to monitor cows for changes in behavior or health when introducing these oils. Regular veterinary check-ups and animal nutritionist assistance can tailor a treatment plan to the herd’s needs. This approach helps integrate natural remedies while maintaining or improving milk production and quality.

Economic feasibility is also important. While essential oils can be a cost-effective alternative to antibiotics, the initial investment in quality oils and training can be high. However, long-term benefits, like reduced veterinary costs and higher milk yield, can offset this. Rising consumer demand for organic and antibiotic-free milk potentially allows farmers to sell their products at premium prices.

Sustainability is crucial. Essential oils align with eco-friendly farming, reducing reliance on synthetic antibiotics and lowering antimicrobial residues in milk and the environment. Promoting a healthier farm ecosystem, essential oils contribute to a more sustainable agricultural model, benefiting farmers and the community.

Proper dosing and application methods are crucial for administering essential oils in treating mastitis. Topical application directly to the affected udder is effective, requiring dilution with a carrier oil to avoid skin irritation. Essential oils can also be used in sprays or ointments for veterinary applications. Oral administration, where oils are added to the cow’s diet, ensures bioactive compounds reach the infected tissues via the bloodstream. Precision in dosage and adherence to veterinary guidelines are essential to maximize therapeutic benefits while minimizing potential risks.

In conclusion, using essential oils in dairy farming offers a promising way to combat mastitis and address antibiotic resistance. With careful implementation and a focus on economic and ecological sustainability, essential oils could revolutionize standard treatment protocols in the dairy industry.

Case Studies: Success Stories of Essential Oils in Mastitis Treatment

Recent case studies have shown that basil and bergamot essential oils can effectively treat mastitis in dairy cows. At a farm in Wisconsin, a trial with 50 cows showed that mastitis cases dropped by over 60% in six months after using these oils.

These improvements also led to better animal welfare and milk quality. Cows treated with these oils had less discomfort and inflammation, which improved their health and increased milk production. The somatic cell count (SCC), a key measure of milk quality, decreased significantly.

Most importantly, the farms saw a 40% reduction in antibiotic use. This change saves money for farmers and reduces antimicrobial residues in milk, addressing antibiotic resistance and meeting the demand for natural farming methods.

Comparing Essential Oils to Conventional Antibiotics

Essential oils and conventional antibiotics differ significantly in their antimicrobial action, environmental impact, and resistance development. While antibiotics have been effective historically, they often target a narrow spectrum of bacteria, which can lead to resistant strains. This resistance has made traditional treatments less effective, pushing for new solutions.

Essential oils, like those from basil and bergamot, offer a broader antimicrobial action. Their complex chemical makeup targets a variety of bacteria without encouraging resistance. Compounds in basil oil, such as linalool and methyl chavicol, not only stop bacterial growth but also kill bacteria, reducing the chances of resistance.

HELLO! This Is Your Herd Calling. We’re Sick Today!

· Comments (0)

Thursday, November 14th, 2013

We are so used to leaving voice messages it can only be a matter of time until you hear.

“Good morning Boss. I will be away from the milking line today. If this is an emergency, please check with the veterinarian or better yet – find out why more than eight diseases are going through the barn? Have a great day. Cownt Me Out!

“It’s a Wake-Up Call for the Dairy Industry”

Regardless of how you receive the message about dairy health issues, there is no question that we have already received the wake-up call. Whenever CowntMEout and her peers are fighting health issues, they are still in the lineup and could be having a negative ripple effect because they are contagious, costing money for treatment and losing money because of lowered production. You may laugh off the “cow calling” app on your smart phone, but disease is no laughing matter. The incidence of disease in dairy cattle is increasing. So far the only way to tackle it has been through management practices and veterinary inputs. At least that’s where our thinking has been. It’s time to pick up the phone!

Disease has your barn number. It’s going to call back often!

There is no acceptable level of poor health and, like telemarketing calls, you will receive many visits, at inconvenient times and with increasing frustration. The higher incidence of health problems has risen side by side with the increase in milk yield, which has been sought after and achieved over several decades. However, along with poor health, increased lactation progress has been accompanied by reproduction problems and declining longevity. As if that wasn’t a big enough hurdle, there is also a genetic one. There is clear evidence that negative genetic correlations exist between milk yield and fertility and between milk yield and production diseases. In other words, if selection for production continues unchanged, fertility, health and profitability are going to be put “on hold” permanently.

The Health Games. Sick is costly. Health isn’t free.

As long as our cows continue to function by producing milk, we may be willing to live in denial of health issues. Unfortunately, the list is growing well beyond the number one which is mastitis and includes: displaced abomasums; ketosis; milk fever; retained placenta; metritis; cystic ovaries; and lameness. What is the incidence of each of these in your herd? Do you keep records on all of them? We know from our personal health that you can’t fix what you don’t admit is a problem. Those tiny signs add up until “out of nowhere” there is a health crisis. That doesn’t work for people and it doesn’t work for bovines either.

Bad Prescription. “Take 2 Bales of Hay and Call Me in the Morning!!”

Don’t you just hate it when your doctor takes a laid back approach to your serious medical concerns? Or does that feel like a reprieve? You don’t have to fix what you don’t acknowledge. Or does it boil down to who has the best answer? The vet. The nutritionist. Your neighbour. It probably takes all three but we really need to pull back and start answering the questions about improved health even before mating decisions are made. Huge strides have been made in dairy breeding with the implementation of genomics. DNA analysis has only touched the tip of the iceberg for what is possible in analyzing dairy genetics. This brings your genetics provider (A.I.) onto the health team. All that is needed is the will to change.

What can we do about it? Monitoring. Managing. Action.

You can hire someone to take care of sick animals. You can pay for medication and extra care. Or you can decide to start with genetics and try to raise the genetic health level of your herd. All of these approaches start with the same first step. You must monitor your animals and have detailed data on where, what, when and how health issues are affecting your dairy operation.

The hardest concept when dealing with health is that preventive measures are far better and less costly in the long run than the prescription, medicine and professional caregiver route. There needs to be more preventive action taken at the breeding stage. Here is the first line of defence to reduce the diseases that lurk within genetic code and impact profitability now and for future generations of your herd.

The most crucial first step is to have accurate data. Good complete data that accurately identifies what is happening in the herd. The information needs to be recorded and accurate before the cow is culled from the herd. Dr. Kent Weigel, Extension Genetics Specialist, University of Wisconsin notes. “Current reports often don’t provide enough details to identify exact reasons why cows are culled. Animals can be recorded as ‘died,’ ‘sold for dairy,’ or ‘sold for beef,’ because of low production, mastitis infertility and so on. From that data, you might conclude that mastitis and infertility are the most common causes of culling on dairy farms. However, reported reasons for disposal can be misleading when one attempts to compare the management level of various dairy farms or to draw conclusions about the genetic merit of certain animals or sire families. Furthermore, once culled, that animal will no longer contribute information to genetic evaluations. In effect, by culling time the most important source of health data has been eliminated.”

An ounce of Genetics is Worth Pounds of Cure?

As a result of research he has taken part in, Weigel says producers should not just consider the pounds of milk a cow produces as they weigh their decision about genetic traits.
You want cows that produce a live calf without assistance, cycle normally, show visible heat and conceive when they’re inseminated. Many cows fail to complete these and other important tasks because they have left the herd prematurely.” Weigel went on to say that some animals are culled for “multiple offenses,” such as difficult calving followed by ketosis and a displaced abomasum. “She may then fail to breed back in a timely manner and be culled when her daily milk production falls below a profitable level,” Weigel says. “The farmer might code here as ‘sold for low production’ or infertility or disease. The reported reason for disposal is often a vague indicator of the actual problem.”

Get the Code – Fill the Prescription

Given the unfavorable genetic relationships between milk production and welfare indicators, the most effective route to stop the decline or even improve dairy cows’ welfare is by developing and adopting a selection index in which welfare related traits are included and appropriately weighted.

At a recent CDN (Canadian Dairy Network) open industry meeting, more than one presenter spoke on the genetics of disease and health. The proposed response to this complex topic is to develop one index that incorporates targeted health indicators. We see the logic that cattle who have less mastitis or and lower somatic cell scores represent healthier animals in the herd. Until actual DNA snips are identified for specific health issues and diseases, an index that combines SCC (somatic cell score) with fore udder attachment, udder depth and body condition score to produce the newly developed MRI (Mastitis Resistance Index) will take selection for healthier animals to a higher level. The quantity and quality of the data contributing to these indices is key to how effectively they will identify sires with the healthiest genetics. Isn`t it great that breeders, researchers and genetics providers are working together to move beyond the obvious.

Predict the Disease Proof by Building on What We Know Already

DNA markers for economically important traits could quantify the differences and be used to justify selection decisions on young animals with reasonable accuracy.

Short term, breeding organizations are urged to use available records to include fertility, health and longevity in a selection index in which greater emphasis should be placed on all fitness related traits relative to production traits. Genetic evaluations for health should complement and not replace genetic evaluations for yield.

“The udder is always the place to start evaluating a cow,” Weigel says. “Poor udder traits are the biggest problem, followed by poor feet and leg traits. Naturally, cows that avoid mastitis or injury to their udder are going to be in the dairy herd longer.” The major advantages of the genetic improvement for any trait are that changes are cumulative, permanent and cost-effective.

Who Will Answer the Call First?

Ultimately, the successful dairy industry of the future will maintain the gains made in milk production and make equal strides in the identification of healthy cattle. Whether it’s by choice or necessity remains to be seen. It will take everyone contributing accurate data. The breakthroughs in production were made possible by tremendous amount of supporting data. To make similar progress in fighting dairy diseases, the same cooperation in building a database will be needed. Currently in Canada only 4 in 10 herds are participating in the capture of data on the 8 production limiting diseases. In some European countries there is a database of mandatory disease recording that spans more than 30 years.

The Bottom Line

Some will write off the concerns raised here as over dramatic. After all, personifying your cows as phoning in sick is beyond belief. We all know that 21^st Century contented healthy cows won`t phone in. They’ll text: “Guess what Boss? I’m healthy and I’m pregnant!”

The ones who are prepared for that call will be laughing all the way to the bank.

The Udder Side of World Dairy Expo

· Comments (0)

Monday, October 14th, 2013

I thoroughly enjoyed sitting at ringside at 2013 World Dairy Expo in Madison, Wisconsin and applauded the Judges as they expertly placed the lineups. As 2500 dairy cattle were being placed it became obvious that the difference between the winners and the also rans often has a lot to do with the udders. At every dairy show, the Judges’ comments waxed eloquent about “mammary systems”. Spectators too were impressed. More than once I overheard, “I would be delighted to take the bottom three in that class home to my milking string!”

For an Ontario girl travelling with the Bullvine team, the challenge wasn’t whether I could place the classes or accurately rhyme off the pedigrees of the cattle in the ring. No. For me the challenge is to come back to the table with a bigger, better, brighter story than my two geneticist and perfectionist cow men. As I watched those milking classes and thought of the practical side of dairy operations, I was inspired to take the opportunity to take a closer look at the more than 400 commercial exhibits that bring their displays, videos, brochures and energetic sales teams to World Dairy Expo.

Imagine my delight when I discovered well-informed enthusiasts who shared their passion for the dairy business from a slightly different perspective than the show ring. It didn’t take too long for me to confirm a simple truth that I already knew. While all of us cannot achieve the udders that place 1 to 20 at World Dairy Expo, every dairy operation succeeds or fails on the quality and quantity of the milk produced every day and thus, by extension, the health and quality of the udder itself. Thus I set out to find out what is new relating to udders and what specifically can I learn that I can share with others who seeking improvement.

Cross-Over Technology

Two companies that stand out looking back on my WDE experience, are Qscout (Advanced Animal Diagnostics) and Vi-Cor. Both use the non-agricultural expertise, to provide solutions for dairy related issues. Too often we as an industry can be blamed for trying to reinvent the wheel. With so many similarities to human health, reproduction and even environmental issues, years are wasted when dairy solutions could leap forward on a parallel path.

Catch the Symptoms Before Mastitis Catches You

Dairy operations have many recurring issues to deal with, but one for the most frustrating and costly is mastitis. By the time it’s obvious, you are already losing money and days of delayed milk shipment due to the time required by commonly used current tests. Although there are effective treatments on the market, it is exciting to consider faster less costly options.

In April 2013 Advanced Animal Diagnostics (AAD), a developer of rapid on farm diagnostics closed a $6 million dollar venture capital financing from Intersouth Partners, Novartis Venture Funds and private investors to launch Qscout™ MLD. Looking slightly larger than a car battery, the Qscout™ MLD is an easily portable unit which is used for more accurate detection of subclinical mastitis in individual quarters. With very simple, ergonomically designed operation the Qscout was a crossover envisioned from human health diagnostics by 2001 AAD founder Rudy Rodriguez

Each test on the market or in development at AAD will be processed by the Qscout™ automated reader, so producers will be able to run multiple tests on the same instrument.

The first test marketed by AAD is the Qscout™ MLD. The benefits of minimizing subclinical mastitis in the fresh cow have long been documented through increased milk yield and quality and improved reproduction. A recent study showed detecting subclinical mastitis with the Qscout MLD and treating only infected cows at dry-off also has benefits. Antibiotic use was cut by 47% without an increase in infection rates 10 days after calving when compared to more costly traditional blanket antibiotic treatment. According to AAD, funds will also be used to study use of the Qscout MLD test at other times during lactation.

Gary Winter shares his enthusiasm for Qscout. “ It is new breed of technology that sees infection long before symptoms occur. It’s a brand new way to detect mastitis. More accurate than CMT and SCC, and providing more rapid results than culture.” He backed up the claims with financial figures. “Mastitis costs the U.S. dairy industry $2 billion annually – that’s $200 per cow. With reliable early detection made possible by QScout MLD, you can reduce that cost and generate an extra $50 per cow.” Most convincing for me was that all four quarters are individually tested and not the more common averaging which could let a cow slip below the early detection radar. An average is not nearly as useful as 4 specific tests, which is what you get with a differential cell count by quarter. Secondly, the testing takes just 3 minutes (on average) per cow. At approximately, $15,000 this technology is not cheap unless or until you accurately add up current costs incurred by Mastitis across staff time, withheld milk, medication costs and, most importantly, the effect on the healthy growth, development and reproduction of the milking herd.

Water, Water Everywhere… it’s more than just a drink

Water touches the dairy operation in countless ways from the obvious use for drinking to countless cleaning applications, not only for the cows, but for the facility, equipment and mixing into feed and medication. In fact, any applications that water have for human health, apply also to bovine health. We are all recognize how crucial a safe water supply is to our town water systems. Bou-Matic is currently working on dairy farm applications that derive from that well-established, well-tested, statistically effective supply of water. In speaking with Tony Spaeth he outlined how test farms in the north east, north west, Florida and New Mexico are gathering results. “Phase one will focus on water supply, parlor hoses and pre-dip. The next phases will look at hoof issues and post dip treatments.” There are four sizes of this system, ranging from $20,000 to $85,000. Once again, the value comes from working out the savings earned from vastly improved SCC counts, healthier teat ends, and improved skin condition and the corresponding savings in reduced medication, improved health and the bottom line effect of improved herd health.

Mastitis … How Are Your Cows Behaving?

Once early detection of mastitis becomes a priority in your dairy management program, you will be attracted to leading edge technologies such as those developed by AfiMilk. With data and trials and satisfied customers backing up their claims, their tool is another that has great potential. Attachment times, flow rates, milking curves and milking times are gathered by AfiFlo and processed by AfiMilk herd management software in the computer. This data is extremely helpful in analyzing herd health and parlor efficiency. AfiFlo, combined with the AfiMilk system can detect mastitis at a very early stage. This factor alone makes AfiFlo extremely economical.

Of particular interest, is the foot monitor that by monitoring activity, including resting periods, is proving to be a valuable tool in monitoring herd health.

Udder Health — From the Inside Out

Once the subject of udder health comes into focus, you have to start looking for ways to learn more. I had a brief but intriguing conversation with Mario Flores of ViCOR. He described the Udder Dissection seminars that they have been conducting. Too often he feels that we treat the udder from an outside-in, end of the teat method. He explained the physiology of the udder and that by dissecting the udder everyone gets a practical understanding of what a healthy udder looks like and the best practices for maintaining udder health.

The Bullvine Bottom Line

Standing at the bottom of the line in the show ring at World Dairy Expo still sets you in the top percentile of show winning dairy breeders.

Placing at the bottom of the line in the milking line means you are less than exceptional. It also means that your profitability and sustainability is negatively affected.

Udder health must be the #1 priority. New technology is responding with innovative solutions to these issues. What are you doing to be udderly exceptional?

Better Decision Making by Using Technology

· Comments (0)

Tuesday, July 30th, 2013

At an ever increasing rate new equipment and information becomes available that dairy farmers can use to advance the way in which they manage their herds. The early adopters often go out on a limb and install systems on their farms that they hope will make their operations more profitable. Making better decisions or having information that gives advance notice of potential cow problems is critical to increased herd profit.

New on the Scene

Recently the Bullvine took the opportunity to get close-in on a new piece of equipment by visiting two reference farms. This equipment is called Herd Navigator™ (HN), a product of DeLaval/FOSS, and it has just completed verification in Canada using four Ontario dairy farms. It had been developed, field tested and implemented in Europe and at the present time it is being installed commercially in additional farms in Canada.

In brief what it does is take milk samples from selected cows on selected days and, based on the analysis of the milk, provides reports for herd managers to use. As one would expect, this requires equipment for sampling (a sampler and a sorter) and testing (on-farm mini lab), computer software and linkage to the herd management software used on the farm by the herd manager, the nutritionist or the veterinarian.

Designed as the next tool for top herds

The focus of HN is cows in robotic and parlour herds from calving to being pregnant again. (Read more: Robotic Milking: More than just automation it’s a new style of herd managment) Nancy Charlton DVM (Nutrition & Herd Management Specialist, DeLaval Canada) started her explanation and demonstration of HN by saying that “…. lets start with the basics. A herd must have an effective cow and heifer transition program. That is a well proven fact. HN is then a tool to make very good managers even better at their job.” That made me want to listen even harder to Dr Charlton as she very adeptly went through the various procedures and reports for HN.

Multi-Purpose Tool

HN takes a milk sample at prescribed times and provides information on four areas important to herd management and profitability. Users of the HN™ system set up Standard Operating Procedures for all four areas, reproduction, mastitis, ketosis and urea level in the milk. When results for metabolic conditions exceed owner determined levels an alarm sounds (more correctly a report is generated) notifying the herdsman. Acting before a cow becomes a problem means less cost, more production and more profit.

It is a well known fact that managing REPRODUCTION takes detailed recording, considerable staff time, is a significant expense and reduces the average revenue per cow per year. For the time period starting 30 days before the voluntary waiting period until 55 days pregnant progesterone levels are monitored on critical days. Herd managers have access to detailed reports including: changes in progesterone levels; heats and the best time to breed; prolonged post partum anestrous; follicular cysts; luteal cysts; potential pregnancy; and early embryonic loss or abortion.

Life for herd managers would be much simpler if MASTITIS did not occur. But that would be a perfect world. HN uses the milk sample to measure the enzyme Lactate Dehydrogenase (LDH) which is released into the milk in an affected quarter during inflammation. Increasing LDH levels are highly correlated with the increased presence of somatic cells and the early stage of subclinical mastitis. The herd manager can choose to monitor the situation or to treat the cow immediately. At the very least the manager can look the cow up and make a visual or hands-on assessment. The creators of HN see using LDH as a more accurate way of determining the presence of mastitis. The frequency of testing cows for LDH is recommended as once per day for the first thirty days of lactation and after that it depends on the cow’s history and the herd’s standard operating practice.

The metabolic disease KETOSIS can be a thief of profit for cows by causing the loss of milk, lowering peak milk yield and cost of treatment. HN monitors the concentration of ketone bodies in a cow’ milks early in lactation. Measurements start on day four of lactation and continue until readings indicate there is a small chance of ketosis occurring. It is significant that HN reports on subclinical ketosis. Thus alerting the herd manager to take action before full blown ketosis occurs, either by altering the fresh cows diet or by treating the cow. Recent research indicates that subclinical ketosis is much more prevalent than dairymen are aware of. Potentially all herds are losing production due to subclinical ketosis and do not know it.

The final area that HN monitors is the UREA level in the milk a cow produces. This is similar to the MUN (milk urea nitrogen) service offered by CANWEST DHI but does not require that the owner wait until a milk recording test day. As yet this part of HN may not get as much use as the three previously mentioned areas. It is important to know if protein level in the diet are too high, just right or too low. Over feeding protein, the expensive part of the ration, costs money while under feeding means a cow’s potential is not being achieved and other feed ingredients are not being fully utilized. From what I heard when speaking with the two herd owners, that I visited, this area has yet to be ‘discovered’ for use by HN owners.

In summary these four areas give herd managers the opportunity to increase the profitability of their herds from just a milk sample.

Information Provided

At any time the herd manager can go to his computer and call up any reports. HN is definitely designed for larger herds that manage cows by groups. It provides information so that individual cows within the groups can have their current problem addressed. Only problem cows need to receive the attention of the herdsman.

Sytse Heeg of Heegstee Farms commented “I only need to give my attention to cows with problems. It would not be possible for my wife and me to manage without HN. We have 110 cows milking on two robots, all the young stock and our family to attend to every day and also the field work during the summer time. We do have assistance from my father part time and a summer student. I am so much more in control of my herd than I was before HN. And I am getting the results (profit) I wanted to get. Already 4 kgs more milk per cow per day with cows back in-calf as well as very low levels of mastitis and ketosis. In non-busy times it is even possible for us to take a vacation. But don’t forget I can remotely watch what is happening back home.”

At Elmwold Farms (Buchner Families), Jennifer is responsible for searching out the details from their 170 cow 3x herd that on the day I visited were producing, on average, 2.8 kgs (6.2 pounds) of fat & protein per day. When I visited Jennifer was on vacation so father (Chris) and brothers ( Greg and Derek) and cousin (Kevin), over a cold ice tea in the shade on a very hot summer day, described the many ways that their farm uses HN to better manage their herd. Chris Buchner provided the details. “Our herd is focused on efficient high fat plus protein yield. That is what we are paid for kgs of fat and protein sold off-farm. But it is more than that. We were having too many cows on holidays, aka in the dry pens, too much of the time. We calve the vast majority of our heifers before two years of age so we give a bit of a break in having them calve back but the herd average calving interval is 12.6 – 12.8 months. We are running a 24% pregnancy rate, we average 2.2 inseminations per pregnancy, our reproductive cull rate has gone from 28% down to 22%, the vast majority of our cows are pregnant by 120 days into lactation and using the urea numbers we have been able to lower our TMR from 18 to 17% protein. We purchased HN to improve our daily management of cows by focusing on cows outside the norm and to use our facilities to their maximum. We will soon build additional cow housing and will give more attention to our fresh cows with one pen for fresh heifers only as we already know that they get pushed out of the feed bunk by older cows in the fresh group. We looked at using pedometers but after seeing how much more HN could do we made the decision to purchase it. We are very happy we decided to go this route. Our family operation is growing and I am proud to say that the next generation is keen to be profitable dairy farmers.”

Cost Benefit

Top notch herd managers always want to know the cost benefit of any input, service or tool. The DeLaval website suggest that using HN a herd can increase revenue by $330 US$ (250 euros) per cow per year with annual material costs of 130 US$ per cow and an equipment cost of 500 US$ per cow for a two hundred cow herd. All of these numbers do not include the savings in feed for fewer cows (milking and dry) as well as the need for less housing facilities. Definitely it does require that a herd be of sufficient size to justify the initial cost of the equipment.

Another thing about the HN system is that it does all the work and testing thus allowing the herd manager to avoid the time to search out cows and do cow side testing. And, best of all, it does it before there is a problem not after the fact.

Muhieddine Labban (Automated Milking Systems Manager at DeLaval) sees the benefits in these ways “I like to call it return on investment with the results being: 1) accurate feeding – lower cost and waste; 2) lower cull rate; 3) lower use of antibiotics; 4) higher production per cow; 5) more effective use of the herd veterinarian; 6) higher pregnancy rate; 7) fewer inseminations lowering costs and semen used; 8) less herd manager frustration; 9) more family time for the dairy producer; and last but not least 10) the use of technology which will encourage the next generation to be dairy farmers”. An impressive list for every herd managers to consider.

The Bullvine Bottom Line

For breeders looking to manage better and increase their per cow profit, more attention to cows needing individual attention is an avenue to pursue. It definitely does pay to have cows reach peak production, avoid mastitis and get back in calf as quickly as possible. Knowing the facts to base decisions on is the way to go.

From Fantasy to Reality – Top sires to address herd culling problems

· Comments (0)

Thursday, November 15th, 2012

In our recent article, Fact vs. Fantasy – A realistic approach to sire selection, we highlighted the need to choose sires not just on ideal conformation goals, but to also match your sire selection to the key management challenges your herd faces. In typical Bullvine style we wanted to take this one step further and to go from fantasy to reality and identify just what sires will help address these top culling issues.

The Bullvine’s Realistic Approach: Breed to Minimize Your Profit Thieves

In the previous article, we recommended minimum sire proof levels for total index, female fertility, somatic cell score and feet & legs in both the US and Canadian genetic evaluation systems. Since we only have access to DGVs from CDN, all values quoted in this article will be in Canadian terms.

Some considerations set for sires to qualify for consideration are worth repeating:

A minimum LPI/TPI value (+2000) was set to address the problem of cows being culled for low production;
Sires had to be on an active marketing list of a North American AI organization; and
Sires with only genomic evaluations had to have been born in 2011 or, in other words, they are in the initial stages of their sampling time.

Just a reminder of the minimum values The Bullvine set for bulls to be considered.

Lifetime Profit Index > +2000
Daughter Fertility > 100
Somatic Cell Score < 2.90
Feet & Legs > +5

INFERTILITY: You can’t make milk if you can’t make calves

Breeders know that there is a difference in bulls’ daughters’ ability to become pregnant. It’s probably one of the most important profit metrics on most herds. This is measured as Daughter Fertility in Canada and Daughter Pregnancy Rate in the USA. This information has been available for some time, yet it still seems to be given little heed when sires are selected for use in A.I. and herds.

The Bullvine offers the following sires for use by herds wishing to genetically address infertility.

GENOMICALLY EVALUATED SIRES: ranked by DGV Daughter Fertility Index

111 Ever-Green-View FONSY (Super x Shottle)
110 Brant-View ALTAOTIS (Observer x Active)
110 Latuch Trigger TREK (Trigger x Ramos)
109 Rosylane-LLC JOSIAH (Jives x Ramos)
109 Blue-Horizon ALATASUPLEX (Super x Planet)

DAUGHTER PROVEN SIRES: ranked by Daughter Fertility Index

110 Badger-Bluff Fanny FREDDIE (Oman x Die-Hard)
107 Synergy ALTAJENKINS (Mac x Shottle)
107 Mainstream MANIFOLD (Oman x Marshall)
107 Co-op Oman CAVANA (Oman x Hunter)
106 Crackholm FEVER (Goldwyn x Blitz)

MASTITIS – a bane to producing high quality milk

No producer wants mastitis, the cost of loosing a valuable cows, or the possibility of having a tanker load of milk lost due to antibiotics in the load. Additionally milk producers don’t want their vet visit time consumed with mastitis problems. Can mastitis be lowered by using genetic evaluations? “Yes!” claim many producers who know from experience that the daughters of bulls with an SCS over 3.10 are problems. Sure, they may be fine in their first lactation but in later lactations they are usually more prone to mastitis. The Bullvine offers the following sires for use in herds that wish to avoid mastitis, as much as possible:

GENOMICALLY EVALUATED SIRES: ranked by DGV SCS Index

2.22 Coyne-Farms JACY (AltaIota x Massey)
2.32 Welcome ADOLF (Shameless x Ramos)
2.40 Oconnors BAROMETER (Garrett x Shottle)
2.47 De-Su ALTAHALEY (Alta Meteor x Goldwyn)
2.48 Stantons EVEREST (Observer x Shottle)

DAUGHTER PROVEN SIRES: ranked by SCS Index

2.45 Co-op Bosside MASSEY (Mascol x Bret)
2.54 Lirr Drew DEMPSEY (Goldwyn x Derry)
2.62 Coyne-Farms DORCY (Bolton x Bret)
2.62 Coppertop DOBERMAN (Shottle x Granger)
2.63 Crackholm FEVER (Goldwyn x Blitz)

Feet and Legs – Vital for High Performing Cows

The heritability of feet & legs is low (.20 to .25) but there are significant differences between sires in their ability to sire animals with functional feet and legs, especially feet. The costs mount up when you consider that cows with sore feet do not come in heat. And their feet must be trimmed more often. On top of that they require medication. In the end, there is milk withdrawal and definitely there is a loss of milk production. The Bullvine offers the following sires for use in herds that care about reducing their costs and losses due to feet and leg problems.

GENOMICALLY EVALUATED SIRES: ranked by their DGV Feet & Legs Index

+16 Blue-Horizon ALTASUPLEX (Super x Planet) Side View +7, Rear View +10, Foot Angle +7
+15 Ronelee Shottbolt DENZEL (Shottbolt x Outside) Rear View +12, Foot Angle +7.
+14 Seagull-Bay HEADLINER (Robust x Planet) Rear View +12, Foot Angle +10.
+14 De-Su RANSOM (Robust x Ramos) Foot Angle +10, Heel Depth +7. Bone Quality -1.
+13 Farnear –TBR- BH CASHMONEY (Observer x Goldwyn) Rear View +10.

DAUGHTER PROVEN SIRES: ranked by Feet & Leg Index

+16 Gen-I-Beq BRAWLER (Baxter x Shottle) – Foot Angle +12, Heel Depth +13.
+15 Crackholm FEVER (Goldwyn x Blitz) – Bone Quality +10, Rear View +11, Rear Set +13.
+14 Lirr Drew DEMPSEY (Goldwyn x Derry) – Foot Angle +11, Heel Depth +8, Rear View +9.
+14 DANILLO (Goldwyn x Oman) – Foot Angle +12, Rear View +13.
+12 Va-Early-Dawn SUDAN (Jammer x Sailor) – Foot Angle +8, Rear View +13. Rear legs straight.

THE BULLVINE BOTTOM LINE

The sires recommended here are genetically superior for reducing the nagging problems of fertility, mastitis and feet. At the same time, they are superior for their Lifetime Profit Index. Bulls’ daughters that do not reach their potential due to any or all of these limiting factors are not needed on your farm or in the national herd. Choose the best sires that correct the actual problems that you face and thereby give you the opportunity to increase your profit per cow per year. This method of selecting sires is not showy like winning in the show ring is but your bottom line on your year-end financial statement will be a larger number. Taking your goal of greater profits from fact to reality.

FACT VS. FANTASY: A Realistic Approach to Sire Selection

· Comments (6)

Tuesday, November 13th, 2012

How often do you select a mating sire for the reasons you typically cull animals, as opposed to what your perceived ideal cow looks like? Further to our discussion about what the Perfect Holstein Cow looks like we here at the Bullvine started to ask ourselves, “How often do we choose our matings based on what we think the perfect cow looks like? vs. what our true management needs are?” Far too often sire selection is based on the fantasy of breeding that next great show cow or VG-89-2YR instead of facts needed to breed that low maintenance cow that will stay in your herd for many lactations and produce high quantities of milk. Do your sire selections overlook your management needs?

Speedy Selection. Long-Lasting Problems

Discernment is the hardest part of sire selection. Seeing your herd for what it is and what its genetic needs are is step one. Step two is choosing what will work for you almost three years from now when the daughters of the sires you use today will be entering the milking string. The old adage was “breed for type and feed for production.” But how many breeding stock animals have you sold recently based solely on conformation? How many will you be selling in three years based on their type? What are the revenue sources for your farm now and in the future? If your answer is “We get our revenue from the milk cheque from as few cows as possible and with as much profit per cow as possible” then selecting for type could mean that your sire selection is out of alignment with your management needs.

How Can You Tell If You Are You Out of Sync?

One place to determine where your herd has issues is to look at the reasons for and the frequency of culling. Every cow that leaves your herd for any reason other than a profitable sale is an indicator of the issues that could be arising from sire selection that is out of alignment with what is going on in your herd.

The Bullvine found the following information on milking age females that are removed from herds:

Over 35% of cows in a herd are replaced annually. That is costly!
The top known reasons for culling or removing cows are:
- Infertility / reproduction 23.1%
- Sold for dairy purposes 21.4%
- Mastitis 13.8%
- Feet and Legs 9.6%
- Low production 7.6%
- Total 75.5%
The other known reasons for culling or removing cows are:
- Injury 10.0%
- Sickness 7.0%
- Old Age 2.4%
- Diseases 1.8%
- Bad Temperament 0.9%
- Difficult Calving 0.9%
- Conformation 0.9%
- Slow Milker 0.6%
- Total 24.5%

Are You Breeding to Spend Money or Are you Breeding to Make Money?

You may be comfortable with your culling rate especially if it isn’t too far off “normal”. However when you look closely at the cows that remain in your herd how “needy” are they? Staff time, vet calls, hoof trimming, semen, drugs, supplies, extra time in the dry cow pen and removing cows from herds before they reach maturity – these all add up to significant dollars down the drain. Therefore, anything that can be done in sire selection to minimize these costs goes right to improving the financial bottom line. All unbudgeted costs mean less profit. If an animal is culled early, it does not matter where she placed at the local show or that her sire was a popular bull that left fancy udders. If he also left poor feet and low fertility, that costs you money.

A More Realistic Approach: Breed for the Bottom Line Not Just the Top Number

Often top bulls for total index are put forward to breeders for their use, without regard for the bull’s limiting factors. The Bullvine doesn’t support that approach. We recommendation that minimum sire selection values be set for the reasons cows are culled so that sires used in a herd don’t create new problems while the breeder tries to solve the current ones.

Here are the Bullvine we recommend the following requirements bulls should meet to be considered for use by bottom line focused breeders:

In Canada
- Lifetime Profit Index > +2000*
- Daughter Fertility > 100
- Somatic Cell Score < 2.90
