Boost Your Farm’s Biosecurity: Essential Offense Strategies Against Dairy Diseases

Boost your farm’s biosecurity: Learn essential strategies to prevent dairy diseases. Are you ready to protect your cattle with effective farm, cattle, and people management?

The proverb “the best defense is a good offense” holds that preemptive methods are often the most successful in sports and the military. This concept directly applies to dairy production, as biosecurity measures are an essential offensive approach against cattle illnesses. The significance of biosecurity cannot be emphasized; it is critical for herd health and dairy farmers’ livelihoods. Dairy farms may reduce disease outbreak risks by proactively adopting biosecurity policies, assuring economic sustainability and animal welfare. These procedures are not just defensive; they are a proactive, empowering approach to illness prevention, putting farmers in control of their herds’ health.

Effective Farm Accessibility Management: Fortifying Against Disease 

Effective farm accessibility management is critical for keeping a dairy farm disease-free. Everyone who enters the farm must wear personal protective equipment (PPE), which includes boots and gloves. Dairy farms may reduce contamination concerns by limiting visitor access and livestock movement. Creating a wall of separation on the farm helps to regulate outside interaction and minimize disease infiltration. Furthermore, disinfecting vehicle wheels and providing disposable footwear for guests are critical elements in ensuring the farm’s biosecurity.

Ensuring Rigorous Cattle Management Protocols: Imperative Strategies for Dairy Producers to Safeguard Herds Against Disease Outbreaks 

Robust cow management techniques are critical in protecting herds from possible disease outbreaks. The first crucial step is the isolation of fresh or ill livestock. This practice, which is the responsibility of every dairy farmer, is critical to preventing the spread of diseases. Newly purchased animals should be isolated for at least 30 days before being brought to the main herd, thoroughly examined, and vaccinated. Ill cattle must be separated from the healthy group to avoid transmission.

Another essential technique is to milk isolated or ill animals separately. Use unique milking equipment or ensure it is well-cleaned and disinfected between usage. This reduces cross-contamination, safeguarding the whole herd from possible infections. The milking facility must also be thoroughly sanitized; equipment should be cleaned and disinfected after each use, and the facility should be deep cleaned regularly to provide a pathogen-free environment.

Furthermore, giving heat-treated colostrum and milk or milk replacer is critical in reducing disease transmission in young sheep. Colostrum and milk should be pasteurized at 140°F (60°C) for 60 minutes to remove dangerous germs while maintaining nutritional content. This method considerably lowers the danger of transferring illnesses like Johne’s disease or bovine TB to calves.

By meticulously applying these comprehensive processes within cow management protocols, dairy farmers may successfully protect their herds against disease outbreaks and assure their livestock’s long-term health and production.

Implementing Effective People Management Strategies: A Cornerstone in Minimizing Disease Transmission Risks on Dairy Farms 

Managing human contact on the farm is crucial for reducing disease transmission risk. One of the most successful ways is to supply disposable footwear to guests. This method reduces the spread of infections that may be transmitted on shoes from other places. To execute this precaution, set up a dedicated space near the farm gate where guests may swap their footwear for disposable choices. Maintain a consistent supply of adequately sized disposable covers and provide visible signs to direct guests.

Furthermore, teaching agricultural workers about biosecurity protocols is critical. Begin by scheduling frequent training sessions emphasizing biosecurity’s significance in herd health. These lessons should address subjects including detecting infectious illness signs, wearing personal protective equipment (PPE), and washing hands effectively. Supplement this training with readily available teaching materials, such as posters and leaflets, strategically placed across the farm. Furthermore, it fosters a culture of responsibility by encouraging employees to report violations of biosecurity rules promptly.

Dairy farmers may minimize disease transmission risks and protect their herds’ general health and safety by strictly limiting farm visits and investing in ongoing education for farm staff.

Fortifying Against Nature: Strategies for Effective Pest and Wildlife Control 

Preventing pests and wildlife from arriving on the farm is crucial to reducing disease transmission risk. Pests such as rodents, insects, and wild animals can carry pathogens that affect dairy cattle, leading to severe outbreaks. Effective pest and wildlife control protects livestock health and ensures a hygienic environment for dairy production. 

To achieve successful pest and wildlife control, several methods can be implemented: 

  1. Physical Barriers: High, durable fences and rodent-proof materials like metal sheeting can deter wildlife and tiny pests. 
  2. Sanitation and Waste Management: Regularly removing waste and securely storing feed reduces pest attractants. In contrast, proper waste management minimizes insect breeding grounds. 
  3. Biological and Chemical Controls: Use predator species or beneficial insects to naturally reduce pest populations. Employ chemical controls like insecticides and rodenticides judiciously, following safety guidelines. 
  4. Habitat Modification: Trimming vegetation, draining standing water, and maintaining dry conditions make the farm less attractive to pests. Sealing cracks and reducing clutter also help. 
  5. Regular Monitoring and Maintenance: Routine inspections and trap setups can identify pest activity early. Consistent maintenance ensures continued effectiveness. 

By applying these strategies, dairy producers can significantly reduce the risk of disease transmission, safeguarding herd health and ensuring sustainable farm operations.

The Bottom Line

Finally, the success of dairy production depends on stringent biosecurity controls to keep animals safe and healthy. Prioritizing biosecurity enables farmers to minimize disease concerns actively, resulting in herd health, operational viability, and food quality. Stringent farm access management, strict livestock and human resource management, and effective pest control are all critical tactics.  Feeding heat-treated colostrum and milk to young cattle lowers disease transmission. Adopting these procedures ensures the future of dairy farming. Farmers that embrace these methods with speed and determination actively avoid disease outbreaks rather than just waiting for them, demonstrating that the most significant defense is a potent offense.

Key Takeaways:

  • Farm Accessibility: Limit access to the farm and establish a line of separation to minimize external contamination.
  • Provide PPE: Ensure that personal protective equipment (PPE) is available for all visitors and staff.
  • Control Visitors: Regulate the number of visitors and ensure they follow strict biosecurity protocols, including vehicle disinfection and providing disposable footwear.
  • Cattle Movement: Restrict the movement of cattle between different areas to prevent cross-contamination.
  • Isolation of Cattle: Isolate new or sick cattle and handle their milking separately to prevent disease spread.
  • Sanitation: Thoroughly sanitize all facilities and equipment to maintain a clean environment.
  • Pest and Wildlife Control: Implement measures to keep pests and wildlife away from the farm to protect against disease transmission.
  • Nutritional Management: Feed heat-treated colostrum and milk or milk replacer to young livestock to limit disease transmission.

Summary;

Dairy production relies heavily on biosecurity measures to prevent cattle illnesses, ensure economic sustainability, and protect animal welfare. Farmers can control their herds’ health by wearing personal protective equipment, limiting visitor access, disinfecting vehicle wheels, and providing disposable footwear. Rigid cattle management protocols, such as isolating fresh or ill livestock, milking isolated animals separately, feeding heat-treated colostrum and milk, and pasteurizing at 140°F for 60 minutes, are essential for reducing disease transmission. Effective people management strategies, such as disposable footwear and teaching agricultural workers about biosecurity protocols, are also crucial. Fortifying against nature, such as physical barriers, sanitation, waste management, biological and chemical controls, habitat modification, and regular monitoring and maintenance, can prevent pests and wildlife from entering the farm. By applying these strategies, dairy producers can significantly reduce disease transmission risks, safeguard herd health, and ensure sustainable farm operations.

Water: Your Most Important Liquid Asset

It would be a rare dairy manager that would choose to limit water as a cost saving management decision.  Managers know the key role that water plays in order for their herds to thrive. Water is the most important essential nutrient behind feed intake, not only of lactating cows, but also promotes growth and development in young calves and older heifers.

The most basic understanding of the health needs of cattle, dictates that dehydration is a negative.  The very nature of the lactating cow requires that sufficient quantities of water must be provided to facilitate milk production.   This is also true at every stage of bovine growth.

Let’s start with how water contributes to the growth of healthy calves because of the way it promotes early and rapid rumen development.  For some water may seem somewhat unnecessary when considering that calves consume milk or milk replacer.  However, a high percentage of milk and milk replacer end up in the abomasum and not very much milk replacer ends up in the rumen.  On the other hand, nearly all the water that calves drink goes into the rumen, where it contributes to fermentation and the grain & water slurry that promotes early papillae growth.

The All Day Calf Cafe

  • It is especially critical for their future growth that water is available to calves throughout the day. Of course the challenge isn’t simply to provide it, but to do so regardless of the weather.  Extremely cold temperatures and the resulting frozen buckets must be dealt with to provide water to calves in hutches in the winter. Under heat stressing conditions water needs are increased 1.2 to 2 fold.  In addition, Dr. Simon Peek, University of Wisconsin, emphasizes that timing is also important.  He urges that water be provided immediately after feeding, even in the winter months.  In general, preweaned calves usually drink about a quart of water for each pound of starter consumed.  This is in addition to their milk or milk replacer.

The benefits of free-choice water for calves:

  • At 4 weeks of age calves with free-choice water drink roughly 95 pounds (12 gallons) of water.
  • Free choice water calves also consume more pounds of starter grain.  One study reported roughly forty-four percent more grain in the first four weeks for calves that had constant access to water.
  • A 1984 study reported that for each extra liter of water consumed there was a corresponding increase in weight gain of 56 grams per day. Weight gains prior to weaning have been shown to lead to greater milk production as a cow.

Nevertheless the real challenge is making sure that the calves actually drink the water. When it is provided at close to body temperature during cold weather, they are more likely to drink. The extra work required to empty and refill water buckets through the day is well worth it because of the benefits of hydration and increased starter ingestion.  Although there can be variation from day to day it is far better to overfill buckets rather than have a situation where calves run out of water. As well, it has been shown that separation of feed and drinking water eliminates contamination and will increase feed intake and body weight gains by as much as 13 and 20%, respectively, compared with having the buckets side-by-side.

Eat, Drink Water and Be Milky

Free choice water for calves may be a newer priority however dairy managers have always recognized that it is important to provide lactating cows with water.  It is not only essential for milk production, growth and healthbut also impacts rumen function, nutrient digestion and absorption.

Every pound of milk a cow produces requires five pounds or three litres of water.  For high producing cows that totals up to 200 litres of water every day.  Reduce the amount of water and you reduce the amount of milk produced.

It is known that cows drink 30 to 50 percent of their daily water intake within an hour of milking.  Clean fresh water must be easily accessible to all cows. An easy benchmark for water palatability is this: “If you won’t drink the water in your barn, neither will your cows.” Water quality and water intake are closely related.

Of course, clean water bowls or tanks are a given.  Basic best practices are as follows:

  • Water bowls should provide 20 litres per minute for cows
  • Water tanks should supply 30 to  40 litres per minute
  • One water trough is needed for every 20 cows
  • Two water sources per group are needed to avoid stress situations for lower ranked cows
  • Water tanks should be easily accessible
  • 2.5 to 3 m of open space around troughs are needed to minimize pushing and shoving

Test the Waters

Toxicity is an issue to be avoided at all costs.  Palatability comes in high on the priority list too.  If the water that is presented fails to pass the taste test, all the benefits are lost.  For these two reasons alone, it is worth considering having the water supply to your dairy tested.  A treatment system may be necessary to reduce sulfate and chloride levels. Visible problems with algae are easy to see and hopefully eliminate.  It is important to minimize algae levels.  There are six types of algae that are toxic to cattle.  Use 35% hydrogen peroxide (8 ounces per 1000 gallons of water) to control algae populations.  It would seem logical to use chlorine to treat water for dissolved iron, magnesium and hydrogen sulfide.  However chlorine concentration over 1000 ppm can result in milk fat depression and reduced water intake.

Is Enough Water Enough?

Once you have determined its safety and palatability, it is critical that you know if your cows are getting enough water for their age and stage of lactation.  The following are indications that water isn’t meeting the needs of your animals:

  • Firm, constipated manure
  • Low urine output
  • High packed-cell volume or hematocrit in blood
  • Considerable drops in milk production
  • Drinking urine or pooled water
  • Cows bawling even when adequate food is present

Causes for Low Intake

  • Corroded valves, clogged pipes, buildup of slime or scale
  • Stray voltage
  • Stress free access
  • Dirty bowls or water tanks

Water as a Sustainable Resource

No discussion of water can be complete without considering the resource itself.  On a dairy farm, water use can range from 12 to 150 gallons per cow per day. This huge difference depends upon who cares about and monitors how much water is used.  Farms that metre their water use and set standards have very little water use compared to farms that don’t, without restricting the needs of the herd.  Best practices for water usage in milking parlors, wash pens and evaporative cooling systems (in warm climates) are the reality of the future. When all is said and done, responsible use of this finite resource will have a direct impact on the sustainability of the dairy industry above and beyond the life-giving value it has in providing nutrition, growth and milk production.

As an example of how water can become a crisis situation today, it is only necessary to look at the current drought in California.  California Governor Jerry Brown declared a state of emergency last month.  Hundreds of thousands of acres will not be planted this spring. Farmers have been refused the water they requested from a federally controlled system.  Farmers who manage the 1.5 million cattle in California are very aware of the dwindling supply of both surface water allocations and groundwater sources.  The state has identified 10 rural towns with less than 100 days of supply remaining. Added to the problem of supply is the increasing problem with contamination.

The Bullvine Bottom Line

Any restriction on the availability of clean, fresh, and high-quality water can limit calf development and impacts cows’ milk production quicker than a deficiency in any other nutrient. Water intake also regulates feed intake. Thus, understanding the importance of water and how to effectively manage your dairy feeding system to provide adequate water intake is very important.

Water is crucial to your dairy management success. Set up a comprehensive water program, not only for its role in cattle nutrition, but for every point water touches your operation from access to delivery, to cleanup and reuse.  Overlook this liquid asset and you will be left high and dry.
