Lameness in Dairy Cattle: Uncovering Why Hoof Health Issues Persist Despite Interventions

Saturday, July 13th, 2024

Unraveling the persistence of lameness in dairy cattle: What underlying factors perpetuate this challenge, and what can be done to enhance hoof health management?

Imagine the daily struggle of walking on a sore foot without treatment. This is the reality for many dairy cows afflicted with Lameness, a chronic condition affecting their welfare and output. Hoof health remains a recurring issue on dairy farms, even after years of identifying causes and seeking remedies. Lameness is a complex disorder influenced by many factors, including management strategies, living conditions, and cow health. These interconnected factors make treating Lameness a challenging problem that requires comprehensive treatment plans. Why is this crucial? Lameness causes pain, reduces milk output, and impacts reproductive health, leading to significant financial losses for farmers. Better welfare and sustainable production can be achieved by understanding and resolving the underlying issues.

Urgent Action Needed: The Unyielding Challenge of Lameness in Dairy CattleEven with several therapies, Lameness in dairy cattle is still a worldwide issue. Studies reveal that Lameness has mostly stayed the same over time. A recent literature analysis showed that Lameness has an average worldwide frequency of 24 percent among dairy cows. Affected by geographical variations, facility types, milking methods, and diagnostic criteria, prevalence rates fall between 15 and 37 percent. Despite attempts to control Lameness with better housing, nutrition, and herd management, these rates have remained high. This underscores the urgent need for innovative and integrated methods of hoof health care to address Lameness in dairy herds.

Genetic Selection and Early Lactation: Complex Factors Driving Lameness in High-Producing Dairy Cows

Analyzing cow-specific elements helps one understand how Lameness presents and persists in dairy herds. Particularly in Holsteins, genetic selection for high milk output has raised disease sensitivity, including Lameness. This is exacerbated by the rumen acidosis-laminitis combination, which is expected in early lactation brought on by too much grain intake. It disturbs rumen function and compromises hoof structures.

Evaluation of dairy cow health and lameness risk depends critically on body condition score (BCS). Cows generally observe a BCS drop during peak lactation—between 60 and 100 days in milk—which results in a smaller digital cushion required for shock absorption. This increases cows’ susceptibility to hoof damage, particularly in the early weeks after calving when metabolic and hormonal changes weaken hoof tissues.

Older cows, those with high milk output, and those with a history of claw lesions all carry more risk. Unresolved hoof problems build up with every lactation cycle, increasing lameness sensitivity. These elements emphasize the necessity of focused treatments targeting genetic and managerial aspects to reduce Lameness in dairy cattle.

Environmental Conditions: A Crucial Factor in Dairy Cattle Hoof Health

Environmental factors significantly influence Lameness in dairy cattle. Animal welfare depends greatly on housing, including confinement facilities with easily accessible or tie stalls. Poorly planned stalls might cause cows to stand for extended durations, aggravating hoove issues. Another essential consideration is flooring; cows like softer floors that lessen limb strain. Concrete flooring, which is standard in dairy buildings, may seriously affect hoof condition. Although softer coverings like rubber mats have advantages, their general acceptance is hampered by cost and maintenance issues.

Access to outside habitats permits more natural behaviors, relieves cows from harsh surfaces, and improves hoof health. Pasture grazing enhances general welfare. Moreover, heat stress from growing global temperatures aggravates metabolic problems and dehydration, compromising hoof structures and raising lameness susceptibility.

Comprehensive Solutions: The Key to Protecting Cow Welfare and Output

The Far-Reaching Impact of Lameness: Evaluating Welfare and Economic Consequences in Dairy Herds

Given its significant welfare and financial consequences, Lameness in dairy cattle is a major global issue for the dairy sector. Lameness causes suffering and discomfort, compromising critical processes like milk production and reproduction. This disorder limits normal behavior and violates basic welfare norms.

Economically, lameness results in direct expenses, including labor, veterinary care, hoove clipping, and therapies. Indirect costs include lower milk output, worse reproductive performance, higher culling rates, and possible long-term health problems, which add a significant financial load.

Early identification is still challenging; studies show that only a third of the lame cows in farmers’ herds are identified. This under-detection exacerbates the issue as minor early symptoms are often overlooked and lead to more severe and expensive Lameness. Therefore, there is an urgent need for improved diagnosis techniques and proactive healthcare plans to identify and address Lameness early.

The Bottom Line

Lameness is still a common problem in dairy herds that calls for a complete strategy despite decades of work and study. While environmental factors such as house design, flooring materials, and heat stress play vital roles, genetic predispositions and intense milk production increase sensitivity. Lameness has far-reaching consequences for decreased animal welfare and significant financial losses for dairy producers. Good preventive and management calls for an all-encompassing plan, including genetic control, better diet, better housing, and close health observation. The dairy sector has to implement this multifarious strategy. Dairy cow well-being may be improved, and a more sustainable future for dairy farming is guaranteed by encouraging cooperation among researchers, veterinarians, and farmers and investing in technical developments and management techniques.

Key Takeaways:

Complexity of Lameness Factors: Multiple intertwined factors at both cow-level and environmental levels contribute to the persistence of lameness.
High Global Prevalence: The average global prevalence of lameness in dairy cows is around 24%, with rates varying significantly based on regional and facility differences.
Cow-Specific Vulnerabilities: Modern dairy cows, especially high-producing Holsteins, are more susceptible to lameness due to enhanced genetic selection for milk production and associated health complications.
Environmental Impacts: Housing type, flooring, stall design, and heat stress play pivotal roles in the incidence and severity of lameness in dairy herds.
Under-Detection Issues: Research indicates that farmers often recognize only a third of clinically lame cows, missing early signs that could prevent progression.
Economic and Welfare Concerns: Lameness incurs significant direct and indirect costs while substantially affecting animal welfare through pain and impaired biological functions.
Need for Integrated Strategies: An integrated approach, combining awareness, technological advancements, and proactive health management, is essential to mitigate lameness effectively.

Summary:

Lameness is a chronic condition affecting dairy cows’ welfare and productivity, causing pain, reduced milk output, and reproductive health issues. Despite various treatments, the global prevalence rate of Lameness is 24%, with rates ranging between 15 and 37%. Genetic selection and early lactation are complex factors contributing to Lameness in high-producing dairy cows. The rumen acidosis-laminitis combination exacerbates disease sensitivity, compromising hoof structures. The body condition score (BCS) is crucial in evaluating dairy cow health and lameness risk. Older cows, those with high milk output, and those with a history of claw lesions carry more risk due to unresolved hoof problems. Environmental conditions also significantly influence Lameness in dairy cattle. Housing, including confinement facilities with easily accessible or tie stalls, can affect hoof health. Poorly planned stalls and inadequate flooring can worsen hoof conditions. Access to outside habitats and pasture grazing can improve hoof health.

Healthy Hooves, Healthy Herd: The Ultimate Guide to Reducing Cow Lameness in Transition Cows

Wednesday, June 19th, 2024

Prevent cow lameness with effective strategies. Learn how to keep your dairy cows healthy and off their feet. Are your cows suffering from lameness? Find solutions here.

As a dairy farmer, you play a crucial role in keeping your herd healthy and productive, especially during essential transition times. Preventing lameness is a key part of this responsibility. Physiological and environmental pressures, particularly during transitional times like calving and late summer through early fall, can make cows more susceptible to lameness. By implementing early management strategies, you can ensure better cows and a more successful farm. This article is here to equip you with the knowledge and techniques to reduce lameness, thereby safeguarding your cows’ welfare and the seamless functioning of your dairy farm.

The Silent Epidemic: Unmasking the Causes of Lameness in Dairy Cows

Study	Location	Herd Settings	Incidence Rate
Cha et al. (2010)	USA	Intensive Dairy Systems	20-25%
Cook and Nordlund (2009)	USA	Freestall Barns	24-30%
Von Keyserlingk et al. (2012)	Canada	Freestall Barns	20-30%
Olechnowicz and Jaskowski (2011)	Poland	Tie-stall and Free-stall barns	10-20%
Phillips et al. (2014)	Australia	Pasture-Based Systems	7-10%

First, one must understand the particular factors causing lameness. Among the most often occurring are sole ulcers and hairy heel warts. Hard surfaces and inadequate foot care lead to sole ulcers and sore sores. Infectious and fast-spreading hairy heel warts—also known as digital dermatitis—cause significant pain and mobility problems.

The hormone relaxin affects transition cows, which are cows that are in the process of transitioning from the dry period to lactation. This transition period, particularly noticeable after calving, makes them more prone to lameness.

It’s crucial to understand the severity of lameness issues. Many dairy herds experience lameness every year, which demands quick and continuous attention. This widespread problem requires strong management plans to be put in place. By addressing lameness, you’re not just improving the health of your cows, but also ensuring the long-term success of your farm.

Navigating the Perils of the Transition Period and Seasonal Challenges

Time	Increased Prevalence of Lameness (%)	Contributing Factors
Pre-Calving	15%	Hormonal changes, increased pressure on feet
Post-Calving	25%	Body condition loss, relaxin effects
Late Summer	20%	Heat stress, standing time
Early Fall	18%	Environmental factors, standing time

Note: Monitoring these periods closely and addressing the respective contributing factors can significantly reduce the incidence of lameness in dairy herds.

Dairy cows depend on the transition period—the weeks surrounding calving—which increases lameness risk. This fragility results from major metabolic and physiological changes, most notably from relaxin. Relaxin softens hooves, which can cause sole ulcers and other hoof problems, even as it helps birth by relaxing tissues.

Late summer and early autumn provide extra difficulties, particularly with heat stress. High temperatures force cows to stand longer, which stresses their feet and increases their risk of lameness. They are reluctant to lie down. Furthermore, climatic elements like humidity and damp weather throughout these seasons affect hooves and raise the danger of infections and injuries.

Understanding these sensitive times helps dairy producers to create plans to reduce these hazards. Correcting bedding and cooling systems during these periods can improve hoof health and lower the prevalence of lameness.

Mitigating the Damaging Effects of Relaxin by Reducing Pressure on Transition Cows’ Feet

Reducing the effects of relaxin depends on lowering pressure on the feet of transition cows. Farmers must design surroundings that inspire cows to lay down, lessening their foot strain. Good stalls depend mainly on enough bedding. The bedding is comfortable and soft, clean, and promotes greater relaxation, therefore reducing hoove pressure.

Think about marathon runners who treat their feet very well to avoid injury. Walking up to seven kilometers a day, dairy cows require the same care. While helping birth, the hormone relaxin compromises the hoof structure as well. Conditions such as sole ulcers or hairy heel warts might result from too much standing. Ensuring cows lay down helps to preserve hoof health and releases immediate pressure.

You can adopt strategic measures to reduce lameness and enhance overall animal welfare and productivity:

Provide Adequate Stall Space: Ensure stalls are appropriately sized and sufficient in number so cows can ruminate and lie down for 10 to 14 hours daily.
Enhance Bedding Quality: Use soft, clean materials like sand or straw to entice cows to lie down and protect their hooves.
Optimize Stall Design: Design stalls to support natural cow behaviors and comfortable movement.
Maintain Appropriate Stocking Densities: Avoid high densities to reduce competition for lying space and stress.
Minimize Time Away from Stalls: To reduce lameness, limit the Time cows spend away from feed, water, and stalls, especially during milking or checks.
Regular Hoof Care: Establish consistent hoof trimming and inspection to prevent minor issues from escalating.
Utilize Grass Surfaces: Allow cows to graze on grass surfaces to promote optimal hoof health, enhance joint range, and decrease pressure points.

By focusing on these strategic measures, you can significantly mitigate lameness, boosting both cow welfare and farm profitability. These strategies have been proven effective in numerous studies, giving you the confidence that you’re making the right choices for your herd.

The Unseen Battle: Combating Heat Stress to Prevent Lameness in Transition Cows

Temperature (°F)	Humidity (%)	Incidence Rate of Lameness (%)
85	40	20
90	50	25
95	60	35
100	70	45

In dairy production, heat stress is a major difficulty, especially in relation to lameness in transition cows. High temperatures may interfere with cows’ normal behavior, causing them to stand more to disperse heat, therefore raising foot pressure and the risk of lameness.

Producers can take several steps to reduce heat stress and encourage cows to lay down:

Enhanced Ventilation: Installing fans and ensuring good air circulation in barns can reduce heat stress. Position fans to target feeding and resting areas.
Misting Systems: Using misters or sprinklers can lower the ambient temperature. Combined with ventilation, these systems are highly effective.
Shading: Providing shade through trees or shelters helps protect cows from direct sunlight, especially in pasture or holding areas.
Hydration: Ensure cows have access to plenty of cool, clean water to help regulate their temperature.
Bedding and Stall Comfort: Comfortable and dry bedding encourages cows to lay down. Focus on stall design with adequate space and softness.

Farmers can significantly reduce heat stress by implementing these strategies, promoting better hoof health and overall cow well-being.

Striking the Balance: The Imperative of Body Condition Management for Dairy Cow Mobility and Health

Body Condition Score (BCS)	Increased Incidence Rate of Lameness (%)
2.0 – 2.5	7
2.6 – 3.0	3
3.1 – 3.5	0
3.6 – 4.0	1
4.1 – 4.5	5

Dairy cows’ movement and general health depend on their body condition, which also affects lameness and bodily condition, which has a relationship that rests in the diet. Cow lameness is more likely when they lose too much body condition when fat stores from their feet are digested. This fat loss weakens the digital cushion, lowering its capacity to absorb weight and stress. Low body condition score cows, therefore, have more risk for unpleasant disorders such as digital dermatitis, also referred to as hairy heels, and sole ulcers.

Balancing mobility and well-being depends on maintaining modest bodily condition. Cows who are neither too lean nor too fat are better able to control the physical demands of milking and consistent activity, considerably lowering their chances of lameness. A good diet that preserves stable body conditions enhances the structural integrity of the hoof and the digital cushion, a soft pad of tissue located between the hoof wall and the pedal bone, increasing cows’ resilience against frequent hoof diseases. Maintaining cows in ideal bodily shape can help farmers lower lameness, extending their herds’ lifetime and output.

Addressing Lameness in the Outer Claws

Foot health in dairy cows is intimately related to their general satisfaction, especially with regard to lameness in the outer claws of the hind feet. Because of their structural orientation and weight distribution, which frequently reflect greater strain and wear, these claws are vulnerable to diseases like warts and ulcers. Reducing lameness, therefore, depends critically on improving cow comfort.

Strategic management is really crucial. While regular hoof trimming preserves correct foot form and lowers pressure, ensuring soft yet durable flooring lessens hoof impact. This preventative action tackles the structural flaws in the outer claws.

Choice of bedding also affects hoof condition. Deep, cushioned beds help cows lie down, lowering their standing Time and foot strain. Furthermore, enough stall width and space help avoid congestion, reducing tension and encouraging comfort.

Preventing certain foot diseases, like sole ulcers or digital dermatitis, mostly depends on diet and hygiene. While a balanced diet high in minerals and vitamins maintains hoof integrity, clean, dry living quarters avoid infections.

By emphasizing cow comfort, structural hoof care, and environmental management, one may considerably lower lameness in dairy cows’ rear feet, fostering general health and production.

The Bottom Line

Stopping lameness in dairy cows depends on good management. Targeting the weaknesses in transition cows around calving and in late summer and early autumn can help farmers reduce this expensive condition.

Key actions include:

Addressing the effects of relaxin.
Make sure cows lie down with improved stall facilities and cooling strategies.
Preserving ideal body condition.

Understanding cow comfort and nutrition in lameness can help improve bovine mobility. Farmers should use these techniques to lower lameness factors and foot pressure, guaranteeing better herds and lowering economic losses. Healthy dairy cows depend on proactive, alert, knowledgeable herd management.

Key Takeaways:

Lameness in dairy cows incurs substantial costs and challenges for farmers, especially during critical periods such as calving and the late summer to early fall transition. Understanding the underlying factors and implementing strategic measures can significantly reduce the incidence of this debilitating condition.

Critical Periods: Transition cows around calving and in late summer/fall are highly susceptible to lameness.
Relaxin’s Role: The hormone relaxin, crucial for birth, compromises hoof health by weakening supportive tissues.
Pressure Management: Encouraging cows to lay down through comfortable bedding and stalls mitigates pressure-related hoof damage.
Heat Stress: Effective cooling strategies during hot weather can prevent cows from standing excessively.
Body Condition: Maintaining a moderate body condition is essential to avoid excessive fat loss from feet and mitigate lameness.
Outer Claw Vulnerability: Lameness predominantly affects the outer claws of rear feet due to cow comfort and potential nutritional issues.
Holistic Approach: A comprehensive management strategy addressing comfort, nutrition, and environmental factors is critical to reducing lameness.

Summary:

Dairy farmers are crucial in maintaining the health and productivity of their herd, especially during transitional periods like calving and late summer through early fall. Preventing lameness is essential due to physiological and environmental pressures, particularly during these periods. Understanding the specific factors causing lameness is essential, as it can lead to sole ulcers and hairy heel warts, causing pain and mobility problems. The hormone relaxin affects transition cows, making them more prone to lameness. Monitoring the transition period and seasonal challenges closely and addressing contributing factors can significantly reduce lameness incidence in dairy herds. Strategies to reduce lameness include providing adequate stall space, enhancing bedding quality, optimizing stall design, maintaining appropriate stocking densities, minimizing time away from stalls, establishing consistent hoof trimming and inspection, and using grass surfaces. By focusing on these strategic measures, dairy farmers can significantly mitigate lameness, boost cow welfare, and increase farm profitability.

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.

Disease	Global Losses (US$ Billion)	India (US$ Billion)	US (US$ Billion)	China (US$ Billion)
Subclinical Ketosis	18	3.6	2.4	1.5
Clinical Mastitis	13	2.6	1.8	1.1
Subclinical Mastitis	9	1.8	1.2	0.75
Clinical Ketosis	0.2	0.04	0.03	0.02
Displaced Abomasum	0.6	0.12	0.08	0.05
Dystocia	0.6	0.12	0.08	0.05
Lameness	6	1.2	0.8	0.5
Metritis	5	1	0.67	0.42
Milk Fever	0.6	0.12	0.08	0.05
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. The US loses $8 billion annually due to veterinary expenses, decreased milk output, and early culling. China’s industrial-scale dairy production and rising demand result in $5 billion losses. Customized disease control plans are necessary to address these losses.

Remember the story of the Princess and the Pea?

She could feel a pea through several mattresses. In our dairy barns, we have productive queens and royal princesses who have that same sensitivity … in their bovine feet. Everything they walk on, sleep on or stand on affects their comfort, health and how long their dairy reign will last.Cows on pasture can choose where to lie down, or more importantly, change to a more comfortable spot, as far as what they walk and lie down on. However, nothing is perfect, and mud, stones, wind, rain and excessive heat and cold can add discomfort to the presumed better outdoor conditions. Looking inside the barn, logic tells us that sand would be the softest, mouldable bedding … but, that would have to be sand that isn’t clogging machinery or providing other problems for the human side of the dairy operating equation.

There are Always Trade-Offs When Choosing Bedding

Efficiency and effectiveness also add to the variables you have to consider when choosing bedding. It might be hugely efficient to have automatic scrapers, slatted floors or automatic spray cleaners but, if these are making cows nervous and causing slips, falls and lameness the efficiency and savings in work hours may be completely eradicated by less production, more illness added vet costs and increased culling. Ultimately cattle welfare is complicated.

Whether your cows are princesses or queens, your choice of bedding will be influenced by whether it is tie stall, free stall, or open style. Cost and labor efficiency are high priorities to factor in as well.

Well-packed beds, like the excellent ones maintained at cattle shows are definitely cow-comfortable. They require constant maintenance to stay manure free. On the one hand, the added tasks mean that you are very aware of the manure from each cow and the regular observation allows problems or changes in status to be noted and dealt with in a timely and efficient manner. On the other hand, you incur the added labor costs and expense to replace or maintain the pack. Furthermore, the best bedding material for combating lameness may not be best for udder cleanliness. Relative concerns regarding such different problem areas will also influence bedding material recommendations.

“Our mission is to improve the lives of animals through research education and outreach.”

That is the mission statement of The Animal Welfare group at the University of British Columbia goes like this. (Link: http://awp.landfood.ubc.ca/) They studied barn design and management, and their results showed three areas that have the biggest impact on animal welfare:

Providing deep bedding
Professional management with Standard Operation Procedures
The use of technology to detect illness

Deep Bedding Makes the Most Difference in Lameness

The team at the Animal Welfare group at UBC concluded that bedding is the single most important feature that can reduce lameness on dairy farms (From the Hoard’s Dairyman webinar with Dan Weary, the University of British Columbia.) The researchers studied cow comfort and barn design, and the differences in how people build and manage their farms in Canada, the US and China and found that the lying surface provided to the cows made a significant difference.

Farms using deep bedding have 50% lower lameness rates than those who don’t.
The north east of the US has a higher lameness rates compared to California dairies that use deep bedded recycled dry manure solids.
The use of deep bedding reduces hock lesions, with 95% less hock lesion rate.

If you can see the floor under cow, you will have problems with lameness and hock lesions.

Sometimes Big is Better for Cow Comfort

To draw a comparison to human comfort let’s look at bed and breakfasts and hotels. Sometimes the small intimate B&B has the edge because of the one on one attention. However, there are times when the bed may have seen too many guests or is restricted because of the small inn ambience. It’s nice to get a consistent night’s sleep at a big hotel chain with a comfortable mattress. However, back to cow comfort.

Desirable Characteristics of Bedding

There are two driving factors behind good bedding choices. One is cow comfort, and the other is farmer comfort. The two sometimes pull in opposite directions. Nevertheless, cow comfort must win out whenever the decision affects the cow spending most of the day lying down processing feed into milk.

Bedding must be comfortable to lie on.
Because cows are large animals, bedding must offer uniform support.
Coolness in summer and warmth in winter will promote cow comfort.
Dry bedding is critical for comfort and reduction in pathogen growth.
Good footing is essential for injury prevention.
Nonabrasive bedding promotes both comfort and injury reduction.
Besides whatever physical comfort dairy workers need, there are the financial comforts that require that bedding be cost efficient and labor efficient.

Six Cow Comfort Choices

Studies are accumulating data that shows that with increasing comfort daily lying time increases and hock scores improve for lactating and non-lactating cows. Here are some options to consider as part of your environmental and animal welfare strategy.

Compost, or composting material, is used as bedding in open style barns. Cows find this comfortable as observed by lying time. As well, foot and leg health has positive improvement with this system. The nature of the material requires that the facility have good air circulation. Teat cleaning will also need scrupulous attention. Good management is required and includes the challenges of daily tilling and regular replacement of the material.

Geotextile Mattresses manufactured from a variety of materials are commercially available. These may be used in either tie stall or free stall barns. They are marketed as requiring no bedding, but research has shown (see Bernard, et al. and Tucker and Weary) that added bedding makes the mattresses much more attractive to cows. Mattresses are generally installed in rows and come in a variety of sizes to fit typical stall sizes.

Paper may be available inexpensively or even free in the vicinity of paper mills or shredding companies. Chopped recycled newsprint has also been used for dairy bedding. Both can be effectively mixed with other bedding materials. Fineness of chop will influence bedding characteristics. Because the material must be kept dry, storage factors into consideration.

Sand can be an excellent choice of bedding. Because sand is an inert material, it will not tend to promote growth of pathogens, though when mixed with manure, the manure will support pathogen growth. Particle size is of great importance. Too small a particle size (or too much organic matter mixed in) will hold water too well. Large particles (> 3mm) will not be comfortable to lie on. Sand that is naturally occurring has rounded edges and is more comfortable as bedding than manufactured sand that comes from crushing rock. The potentially negative side of using sand as bedding comes in the disposal. In a liquid manure handling facility, sand must be settled out and disposed of. If this could be done in such a way as to reuse the cleaned sand, however, it would become a benefit.

Sawdust and Wood shavings are commonly used bedding materials for dairy cows. They have the advantage over sand of being broken down by microorganisms in the disposal system, but they have the disadvantage of allowing growth of microorganisms (pathogens). Addition of lime to bedding may reduce growth of pathogens. The smaller particle size of sawdust makes it more absorbent than wood shavings and quicker to break down. However, small particle size is also associated with rapid growth of bacteria and other harmful pathogens. Cost and availability tend to be deciding factors in choice of material.

Straw composts well and reduces in volume when composted, better than sawdust or wood shavings. It is important when using straw as bedding that the particle size be small, preferably fitting through a ¾ inch screen, both to increase animal comfort and to shorten breakdown time. Bedding absorbency as well as comfort to animals varies according to the species as well as to the chop size. Straw is an attractive bedding alternative when it is produced on the farm.

The Bullvine Bottom Line

There is much to consider in removing that uncomfortable pea in your dairy facilities. The first discomfort may be with the associated costs and the difficult logistics of implementing change. There is no doubt that cow comfort practices affect lameness and longevity. Accept the comfort challenge and you may find that “happily ever after starts with better bedding.”
