How ‘Feed-Saved’ Trait Can Slash Your Dairy Farms’ Costs

Unlock your farm’s profit potential. Learn how the ‘Feed-Saved’ trait can revolutionize feed efficiency and boost your profits. Ready to cut feed costs?

Have you ever wondered whether you reduce feed expenses without lowering milk production? Dairy producers sometimes spend the most on feed, accounting for more than half of farm expenditures. What if I told you there was a method to produce cows using less feed while producing more milk? Intrigued? You should be.

The Council on Dairy Breeding will release the ‘Feed-Saved’ (FSAV) trait in 2020, marking a watershed moment in dairy breeding history. Consider this: cows that save feed without reducing milk output. FSAV might be the game-changer we’ve all been waiting for. This characteristic assesses individual animals’ feed efficiency based on milk output, body weight, and condition.

This feature combines two essential factors: feed savings for more miniature cows and decreased Residual Feed Intake (RFI). FSAV is stated in pounds of dry-matter intake saved, which has the potential to increase profitability and resource efficiency in your dairy business significantly. The potential for greater profitability should inspire hope and optimism in dairy producers, encouraging them to investigate and use the FSAV trait.

Cutting the Feed Bill

Feed prices are a significant problem for dairy producers worldwide. Imagine operating a firm where more than half of your costs are attributed to a single component; this is the reality of dairy farming. According to the USDA ERS (2018), feed expenditures may account for more than half of a dairy farm’s overall costs. This figure demonstrates the significant cost of ensuring cows have enough to eat. However, it is not only about the quantity of feed; the quality and nutritional value of the feed are also important. High-quality feed is required, but it is expensive, raising overall expenditures. This makes programs like the Feed-Saved (FSAV) characteristic very beneficial. The FSAV trait provides promise by lowering the feed needed while maintaining milk output, alleviating the financial burden on dairy companies, and opening the path for a more sustainable future.

From Estimation to Precision: The Evolution of Feed Efficiency

Traditional approaches to enhancing feed efficiency often relied on approximate estimations and indirect selection criteria. Farmers usually assess overall output levels or body condition and use these markers to estimate feed efficiency. While useful, this strategy lacks the accuracy to optimize savings and profits. It also needs to account for differences in individual feed intake and metabolic efficiency.

Introducing the ‘Feed-Saved’ (FSAV) trait, a game changer in the dairy sector. FSAV compares actual and projected feed intake based on a cow’s productivity, body size, and condition. This exact measurement allows for a far more accurate assessment of feed efficiency, instilling confidence in its effectiveness.

The benefits of FSAV are compelling. It provides a precise and quantitative statistic. Holstein cows with a positive FSAV projected transmitting ability (PTA) may save up to 200 pounds of feed each lactation, lowering feed expenditures, which account for more than half of a farm’s overall expenses. More feed-efficient cows emit less methane, which aligns with environmentally friendly agricultural aims.

While conventional methodologies lay the framework, FSAV provides a more refined, data-driven approach. Its accuracy and potential for significant feed cost reductions make it a strong candidate for broader implementation, providing reassurance about its financial benefits. For farms looking to remain competitive and sustainable, FSAV might be a wise decision.

The ‘Feed-Saved’ trait (FSAV) is a game changer for dairy producers looking to reduce feeding expenditures. FSAV essentially identifies cows that eat less feed while producing the same—or higher—levels of milk. It calculates how much feed a cow saves based on her milk supply, body weight, and general condition. FSAV is stated in pounds of dry-matter intake saved, making it clear how efficient each cow is. Consider a cow that produces the same amount of milk as her contemporaries but consumes much less; this is the kind of efficiency that FSAV seeks to breed into your herd.

Unlocking the Mechanics Behind FSAV: Your Blueprint for Feed Efficiency 

So, how does the FSAV trait work? Let’s examine its two main components to understand.

Feed Saved When a Cow is Smaller: 

This feature focuses on the cow’s physical size. Smaller cows often need less feed to maintain body weight. This does not necessarily imply reduced milk output but indicates more efficient feed consumption. According to the USDA, feed expenditures may account for more than half of a dairy farm’s overall expenses. As a result, choosing smaller, more productive cows may dramatically cut costs while maintaining production.

Feed Saved When a Cow Has a Lower Residual Feed Intake (RFI):

Residual grain Intake (RFI) measures how effectively a cow turns grain into energy beyond what is required for maintenance and production. Cows with a lower RFI eat less feed while producing the same amount, making them more feed efficient. “Because this trait requires individual feed intakes from cows, data must be collected from research herds with that capability,” said Dr. Isaac Salfer, Assistant Professor of Dairy Nutrition at the University of Minnesota. Cheaper RFI equals cheaper feed costs and helps to minimize methane emissions, which aligns with environmental aims.

By concentrating on these two areas, the FSAV trait provides a potential strategy to improve feed efficiency, allowing you to save money while becoming more sustainable.

Why Feed-Efficient Cows Are the Key to Unlocking Dairy Farm Profitability

Choosing feed-efficient cows significantly improves dairy farm profitability. The USDA Economic Research Service has regularly demonstrated that feed expenditures may account for more than half of a dairy farm’s overall expenses, highlighting the need for efficiency [USDA ERS, 2018]. Dairy producers may drastically reduce costs by selecting the FSAV trait.

Furthermore, higher feed efficiency leads to better use of natural resources and energy, which is critical for sustainable dairy production. Studies by de Haas et al. (2011) and Waghorn et al. (2011) have shown that more feed-efficient cows eat less feed and emit less methane. This decrease in methane emissions coincides with larger environmental aims and contributes to lowering the dairy industry’s carbon footprint.

Enhancing feed efficiency via genetic selection achieves many essential goals: it promotes economic viability, increases sustainability, and contributes to environmental stewardship.

Reaping the Benefits of FSAV: A Step-by-Step Guide 

So, how can dairy producers begin to enjoy the advantages of the FSAV trait in their breeding programs? It’s easier than you would imagine. First, choose Holstein bulls and cows with a positive FSAV Predicted Transmitting Ability (PTA). These animals have the genetic potential to conserve feed every lactation, which translates into cheaper feed costs and increased profitability for your farm.

When analyzing genetic assessments, search for bulls with a high FSAV PTA value. For example, a bull with an FSAV PTA of +200 pounds suggests that its daughters will use 200 pounds less feed each lactation while producing the same volume of milk. That’s a substantial savings! Similarly, avoid bulls with negative FSAV levels to ensure you are not choosing for inefficiency.

FSAV is now only accessible to Holstein males and females, but good news is coming. Genetic experts are gathering further data to spread this vital characteristic to other breeds. As this study continues, being prepared and aware will put you ahead of the competition.

Consider your long-term breeding plan. Include FSAV in your selection criteria, among other important characteristics such as milk yield, health, and fertility. Using genetics allows you to make better choices and customize your herd to be more feed-efficient over time.

Remember that the real-world ramifications go beyond your food expenditure. More efficient cows eat less feed, generate less waste, and emit less methane. This is a victory for your farm’s sustainability objectives and the environment. As the dairy industry transitions to more sustainable methods, implementing features such as FSAV now might provide the groundwork for a flourishing, future-proof company.

Stay tuned when the FSAV trait is made more widely accessible and developed. Early adopters often get the most advantages, so immediately incorporate this game-changing characteristic into your herd development plans.

Adding MRP to pasteurized whole milk during preweaning could boost calf development while reducing health risks. The goal is to find the right balance and timing to maximize benefits. Intrigued? You should be. Stay tuned as we explore how this innovative feeding approach could improve dairy farming operations.

Revolutionizing Calf Nutrition: Ditch Conventional Feeds, Embrace Milk Replacer Powder

For years, dairy producers have used traditional calf-feeding practices, in which calves get limited liquid feed. This method promotes early starting meal consumption, resulting in quicker ruminal growth. Calves typically drink 8-10% of their birth body weight in liquid feed daily, which equates to around 3-6 liters. However, this strategy, while encouraging calves to begin eating solid feed, has significant drawbacks. These include slower growth rates and possibly nutritional deficits throughout early life, key stages for determining future production. It’s time to consider a new approach.

Here’s a unique method: mix milk replacer powder (MRP) with pasteurized whole milk (PWM). This innovative technique increases milk’s total solids (TS) content supplied to calves, suggesting several potential advantages. Farmers may supply better nutrition to their calves by enhancing PWM with MRP. This approach encourages rapid weight growth and improves general wellness.

Imagine feeding your calves with nutritionally superior milk during their critical early weeks. It’s not just promising; it’s a potential game-changer. Stay tuned as we delve into the outcomes and implications of this innovative feeding method!

Game-Changer for Calf Growth! Discover How Milk Replacer Powder Transformed These Calves

In a study published in the Journal of Dairy Science – “Effects of milk replacer powder added to pasteurized whole milk over different durations on dairy calves fed ground starter diet with alfalfa hay,” researchers investigated the effects of adding milk replacer powder (MRP) to pasteurized whole milk (PWM) over different durations on dairy calves’ growth and health. The 45 Holstein calves were placed into three treatment groups: the standard protocol (CONV), the short-duration MRP (SHD), and the long-duration MRP (LD). The critical variables assessed were beginning feed consumption, average daily gain (ADG), body weight, feed efficiency, and various health indices.

The CONV group followed a typical feeding program, gradually reducing milk volume. From days 10 to 41, the SHD group had MRP added to PWM, whereas the LD group received MRP from days 10 to 59.

The results revealed that calves in the LD group had a greater body weight and average daily increase than the CONV group. Starter feed consumption was initially decreased in the LD group, but it rose after weaning, balancing total intake. Health markers such as neutrophil counts and rectal temperatures showed that the LD and SHD groups had better immune function and health than the CONV group.

Why PWM + MRP is the Winning Formula for Calf Rearing

When we compare the three groups, it’s clear that calves fed PWM + MRP had significant advantages over those on conventional protocols. Here’s how it played out:

Growth Performance:

  • LD calves showed superior growth, with a final BW significantly higher than the CONV group (99.0 kg vs. 92.4 kg, respectively).
  • At weaning, SHD and LD calves exhibited more excellent BW than the CONV group (80.3 kg and 83.5 kg vs. 76.5 kg, respectively).
  • Important skeletal growth parameters like hip height and body length were also better in MRP-fed calves. LD calves had greater hip height (95.1 cm) than CONV (92.7 cm).

“We observed that calves fed a long duration of supplemented milk replacer powder exhibited the highest growth rates and body weights,” noted the researchers.

Feed Intake:

  • Starter feed intake was initially higher for CONV calves but balanced out post-weaning. SHD and LD groups picked up pace, compensating in later stages.
  • Total DMIs exhibited differences, with the CONV group’s intake at 30.4 kg, notably lower than the LD (46.5 kg) and SHD (40.0 kg) groups.

Health Parameters:

  • The CONV group displayed a higher neutrophil count and N/L ratio, indicating increased stress or immune challenges.
  • Interestingly, cough and nasal discharge scores were lower in MRP-fed calves during the post-weaning period, suggesting better overall health.
  • Rectal temperatures were also slightly higher for MRP-fed calves, potentially linked to increased metabolic activity.
  • Notably, LD calves maintained higher albumin levels (3.52 g/dL) and healthier albumin: globulin ratio (2.32), indicating better overall health.

“Our data underscores that adding milk replacer powder not only promotes growth but also enhances immune status and retains overall health better,” according to the study authors.

Revolutionizing Calf Nutrition Isn’t Just a Catchy Phrase—It’s Essential for Dairy Farmers

Revolutionizing calf nutrition is more than just a catchphrase; it’s a natural and vital step forward for dairy producers. The study’s results demonstrate the significant advantages of integrating Milk Replacer Powder (MRP) into Pasteurized Whole Milk (PWM), suggesting viable approaches to calf raising. So, how does this affect your farm? Let us break it down.

  • Increased Growth and Health Benefits
    The research found that calves given PWM + MRP had higher growth rates and better overall health than their conventionally fed peers. With this combination, calves had larger end body weights and greater hip height. These signs demonstrate vigorous skeletal development, paving the way for highly productive adult cattle. Consider the long-term advantages to your herd’s milk production and resilience!
  • Addressing Starter Feed Intake Concerns
    One disadvantage seen was reduced beginning feed intake during the preweaning stage among calves given the PWM + MRP combination. Don’t worry; these calves increased feed consumption after weaning, correcting for early shortfalls. A prolonged weaning period might help minimize the first drop in feed consumption.
  • Immune and Health Boosts
    Calves fed the PWM + MRP diet had improved immunological indicators, including reduced neutrophil counts and a better neutrophil-to-lymphocyte ratio. These health advantages suggest fewer diseases and reduced medical intervention expenditures over time. It’s more than development; healthier calves need less effort and money.
  • Real-world application and Practical Tips
    Integrating MRP into your calves’ diet might be simple. Begin by gently increasing the TS concentration in their milk, enabling them to adapt without stress. Monitor their starting meal consumption carefully and lengthen the weaning time to ensure a seamless transition. According to the research, these changes are beneficial.
  • Potential Limitations and Considerations
    While the PWM + MRP combination has several advantages, evaluating the possible disadvantages is essential. The research found a transient increase in rectal temperatures and modest digestive alterations, most likely caused by increased TS consumption. Keeping a careful eye on your calves throughout the changeover period will help detect and manage any minor health issues early on.

Finally, realize that each farm is unique. Customize these insights to your unique arrangement while watching calf behavior and health signs. Applying these results strategically may result in healthier calves and more robust future herds.

Optimize Your Calf Feeding Strategy Today: Key Tips

  • Start Early: Add MRP to PWM on day 10 of a calf’s life to ensure an early boost in nutrition.
  • Adjust Concentration Carefully: Aim for a total solid (TS) concentration of 18% when mixing MRP with PWM. This Concentration has been shown to promote better growth and health.
  • Determine Duration Based on Goals: For greater final body weight and fewer health issues, consider continuing the PWM + MRP mix until day 56 of age. This longer Duration provides calves with consistently enhanced nutrition.
  • Transition Gradually: Around day 41, if you need to reduce costs or adjust nutrient intake, start decreasing the MRP ratio. Transition calves from PWM + MRP back to standard PWM carefully to avoid abrupt dietary changes that could impact growth and health.
  • Regular Monitoring: Closely monitor starter feed intake, body weight, and health indicators. Measure and record weekly growth metrics like waist height, hip height, and heart girth.
  • Health Checks: Watch for signs of respiratory issues, digestive problems, or changes in rectal temperature. Coughing, nasal discharge, and eye or ear issues could indicate health complications.
  • Blood Tests: Conduct blood tests periodically to monitor glucose levels, insulin sensitivity, and immune function. This helps you make informed decisions about feeding adjustments.
  • Fatigue Management: When changing feeding protocols, ensure enough time for calves to rest and digest. This minimizes stress and helps calf health.

The Bottom Line

Finally, this research demonstrates that adding milk replacer powder (MRP) to pasteurized whole milk (PWM) throughout various preweaning stages outperforms traditional feeding approaches. Calves fed with the PWM + MRP combination had higher final body weights, better health, and lower stress indicators. This secret milk formula’ provides a successful technique for efficiently and sustainably increasing calf development.

How to Raise a Healthy Calf: Essential Tips for Reducing Mortality and Boosting Growth

Uncover crucial strategies for rearing healthy calves, minimizing mortality, and enhancing growth. Master the techniques for maximizing colostrum and milk feeding to nurture robust calves.

A good dairy herd depends on raised, healthy calves. Despite the challenges of early calf raising, success stories from German research on dairy farms, where a 17% calf loss rate was reduced through effective early rearing, inspire confidence in the potential for improvement.

High calf mortality and disease compromise attempts at herd health and animal welfare. Developing good, efficient dairy cows depends on prioritizing preweaning calf health. This path starts early in the weeks and months of a calf’s life.

The basis of a good dairy cow is a preweaning calf in good condition. From the value of the colostrum period to implementing aggressive milk-feeding programs, your role in rearing solid calves is crucial. Every stride you take is meant to reduce health hazards and boost development possibilities. Ready to discover more? Let’s examine the most excellent techniques for producing muscular, healthy calves.

The Lifesaving Liquid: Colostrum as the First Line of Defense

Early immunity of a calf depends on colostrum, which is the first milk produced by the mother after birth. It is high in immunoglobulins like IgG that guard against illnesses and lower death rates.

Using the “4 golden rules” of colostrum feeding:

  1. Feed colostrum six hours after delivery for best absorption of immunoglobulin.
  2. Three to four liters will help to guarantee enough immunoglobulins.
  3. Make sure colostrum has IgG levels of more than 50g/L.
  4. Maintaining a bacterial level of less than 100,000 cfu/mL helps to avoid illnesses.

High-quality colostrum powder, vitamins, and probiotics strengthen health and immunity by fortifying colostrum, promoting improved gut health and development.

Beyond Immunoglobulins: The Multidimensional Benefits of Colostrum 

Apart from the vital function of immunoglobulins in colostrum, additional elements greatly influence a calf’s early growth and health. Prebiotics, which are non-digestible food ingredients that promote the growth of beneficial microorganisms in the intestines, help good bacteria in the stomach flourish and create a healthy intestinal flora. By exposing antigens and triggering reactions, leucocytes—also known as white blood cells—offer passive immunity and protect against infections, helping the calf’s immune system mature.

Intestinal development, which refers to the growth and maturation of the intestines, depends critically on growth hormones like insulin-like growth factors (IGFs) and transforming growth factor-beta (TGF-β). They support the development of intestinal cells and help to create a robust intestinal barrier, therefore supporting gut lining repair and maintenance for adequate nutrient absorption.

Essential for its development and general well-being, these elements significantly increase the calf’s capacity to resist infections and maintain intestinal health. Rest assured, the unmatched relevance of colostrum in calf raising is highlighted by the combined impacts of oligosaccharides, leucocytes, and growth factors in colostrum, laying the basis for a good and robust existence.

From Economic Pressures to Nutritional Innovations: The Evolution of Calf Feeding Practices 

Historically, economic constraints affected calf nutrition practices, resulting in limited milk-feeding schedules meant to save costs. This approach often sacrificed development and health, requiring reducing milk or milk replacement to around 10% of the calf’s daily weight.

Modern techniques stress ad libitum feeding, a method that allows calves to eat as much as they want, up to 20% of their body weight daily. This approach enables daily weight increases of over one kilogram, fostering strong development and immune system functioning. Essential for this approach is giving enough energy and a balanced protein-to-energy ratio for best growth.

The change from limited to intensive feeding programs prioritizes dairy calves’ health, development, and long-term production, guaranteeing a good foundation for their future success as dairy cows.

The Modern Paradigm Shift: Balancing Energy and Protein in Calf Nutrition for Optimal Growth 

These days, calf nutrition emphasizes balancing protein needs with calories to support development and growth. Calves need a constant metabolizable energy intake for good weight increase, which is necessary for future dairy cow production.

The protein-to-calorie ratio is vital for lean tissue development. Protein helps organs and muscles grow and stops fat buildup. Current feeding plans, comprising almost 8 liters of milk or more than 1.2 kg of milk replacer powder daily, illustrate this complete approach. These strategies guarantee calves get the required nutrients for strong development, unlike limited feeding approaches.

High-quality milk protein is vital, especially considering the high skimmed milk content. Although other proteins, such as vegetables and whey, have been investigated, their effectiveness could be better. Vegetable proteins, like hydrolyzed wheat protein, show potential when combined with skimmed milk powder, providing more flexible feeding plans.

Feeding Intensity and Protein Quality: A New Era in Calf Nutrition 

The quality of protein in milk replacements becomes critical as feeding intensity rises. Milk-derived proteins- including those found in skimmed milk- are recommended for their exceptional digestibility and balanced amino acid composition, which match young calves’ dietary requirements. Early studies revealed that vegetable proteins, such as soy, caused digestive difficulties, resulting in inadequate development and health.

However, recent research has demonstrated improvements in vegetable protein compositions, increasing their viability by breaking down hydrolyzed proteins—like wheat protein—into smaller peptides, digestion and absorption increase. These proteins balance cost and nutrition to promote development and health on par with conventional milk proteins.

Revolutionizing Calf Rearing: The Comprehensive Impact of High-Quality Milk Feeding Protocols 

High-quality milk-feeding programs have transformed calf raising by improving growth rates, organ development, and immunological response. Early and sufficient food delivery from intense milk feeding significantly enhances calf health and vigor.

Accelerated growth rate—not just in weight but also in ideal body composition—including lean tissue and appropriate organ development—is a critical advantage of intense milk feeding. Studies on calves on extensive milk diets find that their gastrointestinal, cardiovascular, and musculoskeletal systems are more robust than those on limited diets.

Furthermore, regular milk intake helps the immunological response. Enough early nourishment helps the immune system mature and operate as it should. An enhanced milk diet reduces susceptibility to infections and illnesses and aids the growth of the intestinal epithelium and mucosal immune system. A well-fed intestinal immune system fights against diarrhea, a main cause of morbidity and death in newborn calves.

Moreover, vital milk intake guarantees the development of the intestinal lining and its immunological properties. Fortified milk formulae, often containing organic acids and probiotics, help maintain gut flora health. This builds resistance against diseases, in addition to helping to absorb nutrients and increase digestive efficiency.

Intense milk-feeding techniques provide a complete calf health strategy, encouraging faster development, improved organ formation, and excellent immunity. These methods show the need for early-life nutrition for long-term animal welfare and performance as they move from cost-minimizing to holistic health and productivity.

The Bottom Line

Starting an intense milk-feeding regimen from a newborn has several advantages. Stronger young animals result from better postnatal development promoted by it and from aid against health problems. Improved colostrum intake and enough milk replacer feeding improve intestinal growth and immunity, hence lowering diarrhea in neonatal and pre-weaning phases. Good early feeding management also increases lifetime performance in dairy cows, therefore stressing the need for contemporary dairy farming.

Key Takeaways:

  • The early calf rearing phase is critical, with mortality rates up to 17% within the first six months in some regions.
  • Colostrum feeding must follow the “4 golden rules”: quickness, quantity, quality, and cleanliness to ensure proper immunity transfer.
  • Feeding colostrum within six hours of birth and in adequate volumes (3-4 L) significantly reduces the risk of illness and mortality.
  • A shift from restrictive to ad libitum milk feeding can lead to better growth rates and higher daily weight gains in calves.
  • Modern feeding strategies focus on balancing energy and protein intake for optimal lean tissue growth and overall health.
  • The quality of milk replacers is essential, with an emphasis on high skimmed milk content and improved vegetable protein sources.
  • Intensive milk feeding programs support the development of the intestinal immune system and protect against neonatal diseases.
  • Proper early nutrition influences not only calf health but also the lifetime performance of dairy cows.

Summary: A successful dairy herd relies on healthy calves, and early rearing strategies can significantly reduce calf mortality and disease. Colostrum, the first milk produced by the mother after birth, plays a vital role in early immunity and gut health. The “4 golden rules” of colostrum feeding include feeding six hours after delivery, ensuring three to four liters of colostrum, maintaining IgG levels, and a bacterial level of less than 100,000 cfu/mL to avoid illnesses. Colostrum also contains beneficial microorganisms, such as prebiotics, which promote the growth of beneficial microorganisms in the intestines and create a healthy intestinal flora. Growth hormones like insulin-like growth factors and TGF-β support the development of intestinal cells and a robust intestinal barrier for adequate nutrient absorption. Modern calf nutrition practices have been influenced by economic constraints, leading to limited milk-feeding schedules. Fortified milk formulae, often containing organic acids and probiotics, help maintain gut flora health, build resistance against diseases, absorb nutrients, and increase digestive efficiency.
