Precision Feeding for Dairy Cows: Why Using a Sniper Approach Beats the Shotgun Strategy

Gain insight into the importance of precision feeding in dairy farming. Are you taking a shotgun or sniper rifle approach to your cows’ nutrition? Discover the optimal strategies today.

Imagine yourself searching for a game. The correct weapon counts: a scoped rifle strikes the target precisely with little waste, whereas a shotgun distributes pellets broadly without accuracy. The same holds for dairy farming and cow feeding. Precision counts; hence, feeding cows poorly is like using the wrong hunting tool: waste and inefficiency follow.

Embracing precision feeding techniques empowers dairy farmers, enabling them to steer their operations towards effectiveness, best performance, and less waste. Just as a skilled hunter hones their craft through patience and practice, a dairy farmer can maximize cow health and milk output with the right feeding techniques. Are you ready to transition from a shotgun method to a sniper’s accuracy? Let’s explore how to make every mouthful count.

The Shotgun Approach: Broad-Spectrum Feeding in Dairy Farming 

Historically, the “shotgun” method—a broad-spectrum approach of overfeeding nutrients indiscriminately—has dominated and defined dairy cow feeding. Like a shotgun spraying pellets broadly, this approach sought to meet all possible nutritional demands without exact calibration. The primary justification was simple: ensuring no cow would fall short of essential nutrients, especially protein, vital for optimizing milk output.

There were many apparent advantages to this approach. Overfeeding seemed like sensible insurance when our knowledge of ruminant nutrition was less developed. Farmers might balance shortages and encourage more milk output by including meals with protein levels at or above 18%. This was advantageous as it used the cow’s capacity to convert extra nutrients into milk, therefore supporting financial goals. Under the theory that more was better, high-protein diets were also supposed to promote general cow health and reproductive performance.

These advantages, however, were theoretical rather than evidence-based. Although the shotgun approach avoided shortages, it also resulted in inefficiencies and unexpected results like lost nutrients and more feed expenses. Furthermore, it disregarded the intricate metabolic mechanisms in cows that may lead to unfavorable results with an excess of nutrients. This formerly fail-safe approach has, therefore, come under closer examination and changed into more exact feeding techniques in contemporary dairy production.

Although it seems like a technique to increase milk output, overfeeding protein has substantial adverse effects. Financially, it causes excellent feed expenses, taxing the farmer’s income. The hazardous high-nitrogen environment the extra protein generates compromises cow health and influences embryo development. Lowering fertility rates and reproductive problems may follow. Therefore, this shotgun strategy of feeding is physiologically and economically wrong. However, with careful monitoring and adjustment, these risks can be mitigated.

From Shotgun to Sniper: The Paradigm Shift in Dairy Nutrition 

Moving from broad-spectrum feeding to precision-based nutrition, like a “sniper,” is novel and required in a developing dairy sector that requires efficiency and sustainability. Unlike the “shotgun” technique, which overloads nutrients, the “sniper” technique employs focused nutrition to suit cows’ demands without waste.

Research shows that lower-protein diets supplemented with certain amino acids have shown higher success. For instance, using feeds like synthetic amino acids, heat-treated soybeans, and blood meal in specific ratios can guarantee that cows get necessary amino acids without excess and balance diets to maintain ideal milk production without negative consequences.

Adopting the ‘sniper’ strategy of precision feeding is a testament to your commitment to dairy production. This approach, by matching nutrient intake with cow demands, not only enhances animal health but also leads to cost savings and increased production. It’s a new era of accuracy and effectiveness in dairy production, and you’re at the forefront.

Precision Feeding: The Transformative Role of Amino Acid Supplementation in Dairy Farming 

Amino acid supplements have significantly increased precision feeding in dairy production by offering a focused approach to satisfy cows’ dietary requirements. Blood meal, high in lysine, heat-treated soybeans with their balanced amino acid profile, and synthetic amino acids, including methionine and lysine, are vital sources of these nutrients.

By limiting extra protein, this exact method lowers nitrogen waste and, therefore, reduces nitrogen excretion in manure. Lowering the need for pricey protein supplements minimizes environmental effects and saves farmers money. Furthermore, an excellent amino acid profile improves cow health, improving milk output efficiency and reproductive function. According to a study by [insert study name], amino acid supplements, therefore, represent a significant step towards more affordable and environmentally friendly dairy production methods.

Precision Fat Feeding: Revolutionizing Dairy Nutrition and Herd Productivity 

Dairy producers have long supplemented cow diets with liquid fats, tallow, or grease. These fats—effective to some degree—have inconsistent reproductive function results and often result in inefficiencies in fiber digestion and milk fat synthesis.

Dairy nutrition has changed lately to welcome exact fat sources like palm, stearic, and rumen-protected oleic fats. These fats, when used in the right proportions, improve dairy cow production and general condition. They provide a concentrated source of energy, support rumen health, and enhance the absorption of fat-soluble vitamins.

First of all, these fats fit perfectly into the cow’s diet without interfering with the fibers’ digestion, guaranteeing effective feed use and good rumen performance.

Moreover, these advanced fat sources have little effect on milk fat depression, supporting consistent milk fat production necessary for high-quality milk output and consistency.

Last but not least, these exact lipids greatly enhance energy balance, fertility rates, and embryo development, thus enhancing reproductive performance.

In a time where precision nutrition rules, changing fat-feeding plans guarantees the best herd health and output.

Precision feeding in dairy production has significant and varied economic advantages. By tailoring nutrition intake to each cow’s requirements, precision feeding reduces wastage and expenses. This focused method guarantees that every dollar spent on feed directly supports milk production, preventing unnecessary nutrients wasted by cows unable to use. According to a study by [insert study name], precision feeding can lead to a [insert percentage] reduction in feed costs and a [insert percentage] increase in milk production, resulting in a significant boost to farm income.

Precision feeding also increases cow health, thereby extending longevity and output. Fewer illnesses in healthier cows help to save veterinary costs and maintain constant milk output. This harmony in nutrition also improves reproductive success, which results in better pregnancies and more muscular calves, increasing economic value.

In the current economic landscape of dairy production, precision feeding is a strategic choice. It not only lowers nitrogen waste, supporting sustainability by improving milk output and feed efficiency, but also offers significant economic benefits. Precision feeding is not just a means of boosting farm income, but a calculated action to enhance the sustainability and resilience of the dairy sector. You’re making a smart financial move.

The Bottom Line

Precision feeding will transform dairy production. Farmers may succeed best with focused nutrition delivery by behaving like ” snipers” rather than ” shotguns,” lowering waste and expenditures. This guarantees cows get what they need for optimal milk output, reducing harmful nitrogen levels and improving health and reproductive performance. Specialized fats and balanced amino acids help digestion and enhance milk quality and general herd output.

The economic advantages are really large, with decreased expenses and fewer nitrogen emissions. Precision feeding supports the current dairy scene and technical innovations for maximum efficiency by matching with the integration of robotic milking systems.

Right now is the moment to start precise feeding. From broad-spectrum to focused nutrition delivery, start to be the “sniper” in your dairy.

Best Practices for Achieving Longer Lived More Productive Dairy Cows

We all wish our cows could meet their potential and live 20 years or longer. However, until we discover the Bovine Fountain of Youth, this remains an elusive dream. Indeed, the average on most dairy farms is only six years. With so much potential, we need to focus on how we can help our cows live long, productive lives.

What Do WE Know About Longevity? Why Aren’t we Using What we Know?

When we develop illnesses, we don’t always have enough information to know what the root cause is.  This isn’t so in dairy farming. Mountains of data have been collected, analyzed and reported but, in general, dairy farmers are not acting up the information. We know what causes involuntary culling. We know what best practices could prevent it.  Unfortunately, the knowing and the implementing are still too far apart.

How Big is the Current Problem with Involuntary Culling?

According to Government of Canada and USDA reports, 30-40% of cows are being culled from herds each year.  Some of this is accounted for because of low production or sales of breeding stock. Those are conscious decisions made for specific reasons.  However, much of the culling is involuntary and is a huge contributor to decreased longevity. The majority of cows are culled because of reproductive problems, poor udder health, lameness and problems with feet and legs. Other illness or injuries also contribute to the high statistics. A culling rate of 40% means that a herd cannot raise enough heifers to meet replacement needs.

What Does this Mean?

High rates of involuntary culling are probably directly correlated to poor levels of animal welfare.  Unfortunately, these health/welfare problems may be indicators of something much more problematic.  The underlying health and welfare problems may be much higher than the rate of culling indicates.  Ito et al reported in 2010 that the actual prevalence of lameness among dairy cows is above 20%.  That percentage is considerably higher than the 2% that are reported as being culled because of feet and leg problems (Government of Canada, 2011). In 2008, 46% of cows in free stalls had hoof lesions (Cramer et al, 2008).  The numbers are similar in the USA.  USDA (2007) reports that four percent were culled for lameness, however an average of 20% to 55% of dairy cows are lame at any one time, depending on the region (Espejo et al, 2006, von Keyserlingk et al, 2013).

Mastitis Has the Same Pattern

In 2011, the Government of Canada reported that about 4% of cows are culled because of mastitis, high SSC or poor udder health. However, Rierkerink et al estimate that mastitis incidence is around 23 cases per 100 cow years.

Who Does A Good Job Of Achieving Longevity?

Best management practices, derived from proven science, are providing some breeders with improved animal welfare and increased profits.

Nevertheless, that doesn’t mean we can’t help our cows live long, productive lives.  We need to put what we know, into practice to extend their longevity.

Are you meeting these herd composition benchmarks?

  • 1st lactation                  24%
  • 2nd lactation                 20%
  • 3rd lactation                  16%
  • 4th lactation                  12%
  • 5th lactation and later   28%

Best Practices that Ensure Longevity

  1. Calf Management – Protocols to raise health and reduce calf mortality.
  2. Implement Indoor Housing Factors – To reduce lameness, injury, and illness.
  3. Benchmarking of farm performance.
  4. Implement an aggressive reproduction program.
  5. Reducing lameness.
  6. Build dairy producer knowledge.

Calf Management

It might seem unusual to start with calf management when you’re talking about extending the life expectancy of cows.  Many place involuntary culling of cows in the number one slot for how to improve longevity. That seems obvious. However, less obvious, but with perhaps even more impact are the calves that never make it to the milking line. Vasseur et al reported in 2012 that pre-weaning calf mortality rates are high in North America. Mortality rate record keeping, which needs to be dramatically improved and increased, is the first step.  Setting a realistic benchmark is also important.  Unfortunately, the Vasseur study also reported “some farms with mortality rates above 19% did not consider calf mortality to be a problem.”

  • Individual housing may not affect small groups but could reduce mortality among larger groups (more than 7-10 animals).
  • The effect of a calf’s illness on her ability to milk as a cow is, in general, underestimated. Recent research (Soberon et al, 2012) shows the effect of pre-weaning growth rates on later milk yields.
  • Failure to implement well-known and documented best practices is a major reason for the continuing high levels of calf mortality on many farms.

They also noted that in Canada there are significant differences in mortality rates between farms. The differences between the highest quartile of farms and the lowest is significant which is positive in so far as it indicates that, when good management practices are implemented, it is possible to dramatically reduce the problems.

The Role of Housing in Dairy Cattle Longevity

The characteristics of the environment that your cows are house in can have a significant impact on their longevity. Even when you have bred for the best possible feet and leg conformation, it can be compromised if the housing situation itself raises the risk of injuries. Some conclude that pasturing is the answer.  More thoughtful study and design needs to be applied to creating the ideal indoor environment for lactating cows.

One Canadian survey found that nearly 25% of Canadian dairy farms scored lameness results at less than 10%. This is lower than the results reported by some pasture-based dairies, proving that it is definitely possible to do make sustainable improvements.

Five improvements:

  1. Take responsibility: Zero grazing puts the responsibility upon the producer to create housing and provide management that does not negatively impact the dairy animals.
  2. Raise the rail height: Simply by increasing the height of the feed rail at the feed bunk to above 140cms from the floor can greatly reduce the risk of neck injuries. (Zaffino, 2012)
  3. Reduce standing time: Standing on wet, concrete floors has a direct correlation with lameness.
  4. Provide comfortable stalls: Depending on the situation, sand or mattresses have been shown to contribute to reduced instances of lameness.
  5. Sufficient Bedding: Switching to sand bedding requires significant change to buildings. Simply adding more straw or sawdust bedding results in hock lesions falling to 31% from the 80% prevalence that is seen when cows are housed on mattresses and no bedding.

Benchmarking of Farm Performance

More often than not, record keeping has a positive impact. Knowing the exact incidence of lameness, mastitis or other illness help set a target for reducing them. Well-managed dairies are reaping the financial benefits of reducing lameness and raising the welfare of their milking herd.  More training, data collection, and peer sharing is a pro-active and positive way to get the results heading in the right direction.

From Candid Camera to Can-Do Care!

Consciously and conscientiously targeting the reduction of involuntary culling is directly correlated to increased cattle longevity. Ensuring that all possible means – health, housing, and genetics – are being responsibly managed – will have a direct effect on reducing involuntary culling and mortality rates.

Reproduction Must Be Managed Better

Much is written about improving reproduction. At one time, the emphasis was solely placed on heat detection.  However, successful dairy managers are now paying particular attention to reproductive management from birth, through rearing, to transition and milking.  Definitely too many breeders are willing to accept less than the best reproductive performance. The first step is acknowledging that there are reproductive problems that aren’t being solved. This must be followed up by bringing in whatever help you can to build improvements into your repro program.

Lameness is Running Away with the Profits

We expect some degree of slowness, bent backs and hesitant steps in the aging and elderly folks we see around us.  However when our dairy herd is limping, falling down or unable to get up, we are forced, whether we like it or not to cull the animal – regardless of her age.  Lameness is a serious problem which adversely affects milk yield.  Research has shown that high yielding cows are more susceptible to lameness.  Too often, we accept this as one of the outcomes of an intensive focus over the past few decades on dairy production. Even though there are excellent best practices that can be used, too often this area is disregarded at the expense of the dairy operation and the welfare of the animal.

The Bullvine Bottom Line

It takes information to make improvements.  You can’t fix what you don’t acknowledge.  Dairy farmers are recognizing that they are responsible for improving their knowledge and understanding of the factors that impact longevity.  Sharing the statistics and setting benchmarks is next.  Most important, however, is implementing an action plan.

Only when improved record keeping and best practices are acted upon, will we begin to see our dairy herds reach their full lifetime potential.
