How to Keep Your Dairy Cows Cool and Feed Fresh for Higher ROI

Thursday, June 20th, 2024

Prevent feed spoilage in cows and boost dairy profits. Learn how to combat heat stress and contamination in your herd. Ready to improve your ROI this summer?

Cows, hailing from Ice Age ancestors, thrive best in the cool 40-60°F (4.4-15.6°C) range. In the summer heat, they struggle, mainly when fed unstable, spoiled feed. This situation isn’t just uncomfortable—it’s detrimental to their health and your dairy farm‘s profitability.

Heat stress and spoiled feed can drastically reduce a cow’s intake and production, making summer a tough season for dairy farmers.

Recognizing cows’ natural preference for cooler climates underpins the need to effectively tackle heat stress and feed spoilage. It’s not only about comfort but also about protecting your herd and maximizing your investment returns. The solution begins with proper feed management.

Unseen Threats: The Real Culprits Behind Feed Spoilage

Many people think mold is the main issue with feed spoilage. Still, the real problem is the rapid growth of spoilage microorganisms, especially wild yeasts, in warm and humid conditions. These tiny organisms are nearly invisible but can cause significant nutrient losses before mold even appears. They thrive when temperatures consistently exceed 60°F/15.6°C, exceptionally when moist.

Wild yeasts lie dormant on crops and come alive when exposed to air, such as during silo opening. Under the right conditions, their population can double in about two hours, leading to massive feed contamination. This rapid growth destroys the highly digestible nutrients crucial for cattle health and productivity.

As yeasts consume sugars and lactic acid in silage, they produce heat and increase the pH, allowing mold and bacteria to grow. This accelerates spoilage and causes significant dry matter (DM) losses, reducing feed quality. Aerobic spoilage driven by these microorganisms can lead to DM losses as high as 30% to 50%, drastically impacting the feed’s nutritional value and profitability.

High Yeast Counts: A Silent Saboteur in Your Silage

Hours Exposed	Yeast Count (per gram)
0	100,000
2	200,000
4	400,000
6	800,000
8	1,600,000
10	3,200,000
12	6,400,000
24	400,000,000

High yeast counts can drastically impact aerobic stability, leading to significant nutrient losses. When yeasts proliferate, they consume highly digestible nutrients for your dairy herd‘s health and productivity. Aerobic spoilage can cause dry matter (DM) losses between 30%-50%. Even short-term air exposure can result in up to a 6% DM loss in corn silage within a couple of days (Ranjit and Kung, 2000).

As yeasts increase, they raise the temperature and pH of silage, making it prone to bacterial and mold contamination. This chain reaction reduces feed quality and digestibility, hurting intake and production. For example, high-moisture corn in an aerobic environment saw a rise in yeast levels and a decline in milk yield over 14 days (Kung 2010).

Financially, a 15°F/8.4°C rise in a ton of 30% DM silage can consume over 6.3 MCal of energy, equating to about 20 pounds (or 9 kilograms) of lost milk production per ton of silage. This increases feed costs as you need to replace lost nutrients and DM, affecting profitability.

Understanding and controlling yeast levels are crucial for maximizing cattle health and improving the return on investment in your dairy operations.

When Prevention Fails: Practical Strategies to Counter Feed Spoilage

When prevention is no longer an option, there are still ways to mitigate feed spoilage’s impact. One strategy is dilution: mix small amounts of spoiled silage with fresh feed, but keep it minimal—a mere 5% spoilage can reduce feed digestibility.

Chemical additives are another tool. They inhibit spoilage microorganisms and enhance silage stability. For best results, choose products backed by research.

Minimizing oxygen exposure is crucial. Smaller, frequent feedings reduce air exposure time, limiting spoilage. Ensure your silage is tightly packed and well-covered to keep oxygen out and maintain feed quality.

Setting the Stage for Success: Steps to Prevent Contamination

Producers can take several steps to prevent contamination and set themselves up for success. The most important thing is good silage management.

Harvesting
Start with proper harvesting. Ensure forage is at the right maturity and moisture level. Chop and process it correctly, fill quickly, and pack it tightly (minimum 45 pounds fresh weight per cubic foot or 720 kilograms per cubic meter). Avoid delays, and cover, weigh, and seal the silage immediately to prevent air exposure.
Inoculation
Consider using a high-quality forage inoculant. Research shows these products improve aerobic stability both in the silo and during feeding. Look for an inoculant with specific strains, applied at 400,000 CFU/g for forage or 600,000 CFU/g for high-moisture corn. This can prevent wild yeast growth and enhance stability. Such inoculants ensure fast fermentation, better digestibility, and extended aerobic stability, maintaining silage hygiene. A proven inoculant maximizes forage quality and strength, leading to healthier cattle and a better ROI.
Monitoring
Regular monitoring is crucial for maintaining feed quality and your cows’ health. By catching early signs of spoilage, you can prevent more significant issues and keep productivity high. Use silage temperature probes to detect potential spoilage. These probes help you spot temperature changes that signal aerobic instability. Regular checks at different depths are essential to early detection. Send samples to a lab for a more detailed analysis. This can reveal harmful microbes and spoilage agents not visible to the eye. Combining these methods ensures your cows get the best nutrition.

The Bottom Line

Unseen threats like wild yeasts can silently sabotage your silage, leading to nutrient and dry matter losses. High yeast counts harm feed intake, milk production, and profitability. Practical steps like proper harvesting, effective inoculants, and vigilant monitoring can help mitigate these issues and protect your cattle’s health.

Feed quality doesn’t just maintain health—it impacts your return on investment. The calm, stable feed can enhance cow performance and improve your financial outcomes. Remember, hot cows hate hot feed, and preventing spoilage results in healthier herds and better profits.

Key Takeaways:

Cows prefer cooler temperatures ranging from 40-60°F (4.4 – 15.6°C) due to their lineage tracing back to the Ice Age.
Heat stress in cows is exacerbated by unstable, heated, and spoiled feed, which fosters harmful microbes and compromises intake, performance, and profitability.
Unseen spoilage microorganisms, particularly wild yeasts, proliferate rapidly in warm, humid conditions, causing nutrient losses before mold is even visible.
Aerobic spoilage can lead to dry matter (DM) losses of up to 30%-50%, further diminishing feed quality and impacting ROI.
Effective feed management strategies include dilution, chemical additives, and proper harvesting techniques to minimize oxygen exposure and microbial growth.
Implementing high-quality forage inoculants and regular monitoring of feed temperatures and stability are crucial preventive measures.
Properly managed feed results in healthier cows, improved milk production, and better overall profitability for dairy farms.

Summary: Cows, native to the Ice Age, thrive in cooler climates, but summer heat can lead to instability and spoiled feed, negatively impacting their health and profitability. This makes summer a challenging season for dairy farmers, as they must recognize cows’ natural preference for cooler climates for effective feed management. The main issue with feed spoilage is the rapid growth of spoilage microorganisms, especially wild yeasts, in warm and humid conditions. These microorganisms cause significant nutrient losses before mold appears, leading to massive feed contamination. Aerobic spoilage driven by these microorganisms can lead to DM losses as high as 30% to 50%, significantly impacting the feed’s nutritional value and profitability. Practical strategies to counter feed spoilage include dilution, chemical additives, and minimizing oxygen exposure.

Subsequent Cuts	Post-Fall	Variable	Variable	General Livestock, Nutrient Supplementation

Harvest timing is essential for producing high-quality hay for champion dairy show cows and heifers. The best time to cut hay is when plants have the highest nutritional value. For grasses, this is just before or at the start of the boot stage, where fiber and protein are balanced. For legumes like alfalfa, the early bloom stage is best to keep high protein levels and good taste.

Timing is everything. If you harvest too early, the hay holds too much moisture and can spoil quickly. If you wait too long, the plant fibers get tough, making them harder to digest and less appealing. Proper timing ensures hay with the most nutrients and best taste, which is crucial for dairy show cows. Palatable hay is critical to getting show cows and heifers full and satisfied. The most palatable hay and silage often become popular with other exhibitors at the show, who may want to get some for their animals. It’s also important to start your show filling with coarser 1st cut hay as it makes a good base for later leafy 3rd cut hay as a finisher.

Precision in Cutting and Drying: Ensuring Optimal Forage Quality

Precision and timeliness are critical when cutting and drying hay to ensure your champion heifer or cows get the best forage. Top exhibitors take pride in both their heifers and the hay they make. Start with a well-maintained mower-conditioner to cut at an ideal height, and crimp stems for quicker drying. Aim to cut between 3 to 4 inches high to prevent soil contamination and wasted feed potential.

Monitor the weather closely and plan to cut hay when you expect three to five days of dry, sunny conditions. This helps the forage dry without moisture issues that could lead to mold.

11 Proven Strategies to Lower Feed Costs and Boost Efficiency on Your Dairy

Saturday, May 11th, 2024

Looking to boost your dairy farm’s performance and cut feed costs? Discover these 11 proven strategies to optimize feed efficiency and enhance your farm’s productivity.

As a producer, you are acutely aware that the sight of a feed truck rolling up your driveway heralds an impending invoice. A simple glance at your expense ledger confirms the unvarnished truth – feed represents your farm’s predominant outlay. Given the relentless rise in feed prices, it is unsurprising that dairy operations nationwide are increasingly directing their attention towards efficiency as a pathway to bolstering overall profitability. Maximizing profitability is fundamentally predicated on two pivotal factors: reducing feed costs and enhancing operational efficiency. Remarkably, feed expenses often comprise over 50% of total dairy farm expenditures, making feed management the primary focus for any diligent dairy farmer. This exhaustive guide outlines various proven strategies that you can leverage as a dairy farmer to minimize feed costs while sustaining or even elevating your milk production levels.

Fine-Tune Ration Formulation

Refining the nutritional balance of your rations is the first step to boosting your dairy farm’s performance and minimizing costs. It would help if you delivered precisely the required nutrients while avoiding excesses that may increase your feed costs and potentially harm your herd’s health.

Precision Nutrition
Begin your journey to refined ration formulation by consulting with a nutritionist. They can guide you in constructing meticulously balanced rations for different segments of your herd, including lactating cows, dry cows, and heifers. The pitfall of oversupplying nutrients is twofold: It needlessly escalates your expenditures and imperils the wellbeing of your animals.
Using Byproducts Wisely
Did you know that non-traditional feeds like distillers’ grains, brewers’ grains, or even bakery byproducts can help cut down on feed costs? You can significantly reduce your expenditure by thoughtfully incorporating such alternatives into the main feed. However, vigilance is needed to keep a close eye on the variability and quality of these feeds. You certainly wouldn’t want to compromise the health of your herd.

Reduce Feed Waste

An indispensable component of your feed improvement strategy should be a concrete plan to reduce waste. This can take multiple forms, including reducing spoilage during critical processes such as feed mixing, storage, and delivery.

Make a deliberate effort to adjust your feeding bunks as well. It can prevent the common issue of overfeeding. Indeed, you would agree that throwing away excellent feed is a cost that no dairy farmer needs—proactively ensuring that your feed delivery system is consistent means that wastage is minimized, optimizing your resources immensely.

Did you know? A dairy farm with 100 cows could save as much as $58,400 annually by reducing shrinkage from high levels to lower ones.

It’s a staggering reality for many dairy farms —as much as 30% shrinkage on forages with bunkers and piles and a further 10% shrinkage on concentrates in commodity sheds. Targeting this waste and making data-driven changes could substantially reduce feed costs and increase overall efficiency.

Maximize Homegrown Feeds

Suppose you grow the majority of your feeds. In that case, it’s crucial that you work collaboratively with your nutritionist to maximize their value, ensuring your dairy farm thrives. This might involve engaging in strategic modifications to your livestock’s diet. To illustrate, if you consistently purchase dry hay, consider reducing the amount and augmenting the corn silage in the diet. This scenario would apply if you have an adequate inventory available. With this potentially more significant investment in purchased protein, you might assume that the total diet cost would skyrocket. However, this isn’t usually the case. The net effect could lead to lowered diet costs, indirectly contributing to boosted performance. This measure not only has the potential to slash expenditure but, more importantly, to enrich the health and productivity of your herd. Maximizing the use of homegrown feed resources that you have close at hand is just another innovative approach to optimize dairy farm operations.

Optimize Forage Quality and Utilization

A top priority in dairy farming is getting the most value from your forage. Optimizing forage quality and utilization is a significant aspect of this. High-quality forage provides essential nutritional benefits for your livestock and is the cornerstone of affordable dairy rations.

Strategic Harvest Timing: The moment of harvest plays a fundamental role in determining the quality and yield of your forage. Harvesting forage either too early or too late can negatively impact its digestibility, potentially resulting in lower nutritional value. Thus, timing your harvest appropriately is crucial in guaranteeing optimal quality and yield.
Prudent Storage and Preservation: Once harvested, storing your forage correctly is paramount to prevent spoilage. The implementation of correct ensiling methods, use of silage additives, and covering your silos or bunkers with high-grade plastic can drastically reduce forage waste. Doing this conserves the nutritional value of your forage longer, thereby maximizing its utility.
Conduct Regular Testing: It’s also essential to conduct regular forage analyses. These analyses provide insight into the nutrient content of your forage, facilitating the calibration of your rations accordingly. Constant testing helps to gauge the nutritional value of your forage better and, in turn, allows for better feeding decisions and optimized feed efficiency.

By focusing on these aspects, dairy farmers can enhance their forage quality, maximize its utilization and contribution to cost-effective dairy rations, yield a healthier herd, and bolster their farm’s bottom line.

Optimize Bunk Refusals

Streamlining your dairy operation with superior bunk reading and feed management practices is achievable. It is essential to reduce bunk refusals to a low rate, conceivably even below 2% for lactating cows. To accomplish this, the feed can be repurposed to nourish replacement heifers or the low group in a free-stall barn.

As you strive to minimize the level of refusals, emphasizing high-quality feeds, frequent feed pushups, and strategic measures to sustain feed along the entire bunk are excellent pointers to consider. The importance of consistent feeding times to maintain a stable animal feed schedule cannot be overstated.

By effectively managing bunk refusals, you save on feed costs and contribute towards improved nutrient efficiency, milk yield, and overall cow health. Pairing this approach with essential animal care practices and advanced technological tools can significantly augment your dairy farm’s output and profitability.

Regulate Nutrient Intake: Do Not Overfeed

Every class of animals in your herd, whether calves, heifers, or lactating cows, should receive a diet that precisely matches their nutrient requirements. This may seem like a rudimentary practice, but you would be surprised how often it is overlooked. The effects might initially be subtle but gradually escalate into significant issues such as impaired growth, lowered milk production, or escalated feed costs.

“In my experience, heifer diets balanced considerably above the National Research Council recommendations are simply a waste of nutrients. It’s like tossing your hard-earned money straight into the wind.”

Note that overfeeding doesn’t equate to better performance. On the contrary, it could lead to inefficient feed utilization and, more importantly, higher operational costs. Nutrient regulation is critical in balancing animal health and farm profitability. Enhancing feed efficiency is vital to increasing productivity on your dairy farm, ensuring that your cows can produce more milk from the same or decreased amounts of feed. However, this isn’t a one-size-fits-all operation. Various strategies can be utilized for optimal efficiency:

Monitor Feed Conversion
An essential component of this process is tracking feed conversion ratios (FCR). This includes pinpointing cows or groups exhibiting substandard performances. By focusing on this metric, you can make adjustments that amplify efficiency.
Implement Grouping Strategies
Grouping cows becomes another crucial strategy here. Cows should be categorized according to their production levels and nutritional needs, ensuring each group receives a ration tailored to their specifications. This method optimizes nutrient utilization and supports overall herd health.
Ensure Rumen Health
A healthy rumen is pivotal to dairy cow feed efficiency. Sustaining rumen health involves providing effective fiber levels, buffer supplements, and adequate water intake. A healthy rumen can enhance digestion and feed utilization, making a noticeable improvement in dairy farm efficacy.

Implement Data-Driven Management Practices

Adopting technology and leveraging data is critical to staying competitive and ensuring optimal performance on your dairy farm. This can be achieved through better decision-making and enhanced operational efficiency.

Precision Feeding Systems
Consider using automatic feeding systems or Total Mixed Ration (TMR) mixers designed to provide uniform and accurately measured rations. This method ensures consistent nutritional intake for your herd. It’s also essential to monitor feed intake. This can be done with the help of electronic identification systems or smart feeding stations. By closely tracking this data, it’s possible to identify changes in consumption patterns early on and adjust rations accordingly.
Milk Production Monitoring
Another important aspect of data-driven farm management is monitoring each individual cow’s milk production. Monitoring health parameters such as weight, digestion, and fertility is also essential. By regularly analyzing this information, you can spot any signs of underperformance and accordingly tweak the feeding strategies. This can substantially boost milk yield and overall farm productivity.
Financial Analysis
On the financial front, regularly reviewing your farm’s financials can expose areas of high expenditure. With these insights, you can devise and implement cost-saving measures, thus enhancing your farm’s economic sustainability. By keeping expenditures under constant review, you can considerably lower feed costs and improve the overall profitability of the dairy operation.

Enhance Herd Health and Reproductive Efficiency

Healthy cows are more efficient in converting feed into nutrient-rich dairy products. This makes maintaining the health of your herd an integral part of achieving feed efficiency.

Preventative Health Measures
Prevention is often better than cure, especially when managing your dairy herd. You can considerably reduce many common health problems by implementing robust herd health protocols. Regular veterinary check-ups, vaccinations, and strict biosecurity measures can help keep your cows healthier, thus improving their ability to convert feed efficiently.
Minimizing Stress
Stress can significantly affect a cow’s health and overall performance. Heat stress, in particular, can lower your herd’s feed efficiency. Install proper ventilation and cooling systems to alleviate heat stress and preserve feed conversion rates. Additionally, providing comfortable and ample resting areas will encourage natural cow behaviors, contributing to their overall wellbeing and productivity.
Reproductive Management
Reproductive efficiency is another crucial factor in maintaining a high-performing dairy herd. Timely heat detection, synchronization protocols, and regular pregnancy checks can improve reproductive efficiency. The healthier and less stressed your cows are, the higher their chances of successful conception are. This not only boosts the productivity of your farm but also contributes to efficient feed utilization.

Cull Nonproductive Cows and Heifers

When adopting strategies to boost your dairy farm performance and cut feed costs, it is essential to consider the effects on livestock health. It’s unfortunate but vital to understand that not all heifers on your farm will prove to be profitable or productive. University research has unveiled a hard-hitting fact: heifers treated for respiratory diseases early in their life are often unable to bear their first calf.

It may be tough to let go, but culling these heifers early if they’ve had to undergo multiple treatments for conditions like pneumonia can save you both escalating feed costs and future disappointment. These savings come from reduced additional feed needed for animals that ultimately may not perform as expected and expensive veterinary treatments.

Furthermore, it’s worth noting the impact of overpopulation on your farm’s efficiency. Raising more replacement heifers than necessary can lead to overcrowding and higher feed costs, a scenario you’d want to avoid. So, aim for a balanced herd that aligns with your farm’s size and resources. Doing so ensures that each member of your herd is productive and contributes positively to your dairy farming business.

Minimize Nonproductive Days

Pay attention to the timeframes in which your cows are productive to maximize profitability and efficiency. Any period where cows dry for longer than 60 days or heifers are aged over 22 to 24 months at first calving should be considered nonproductive days. These periods represent additional feed costs without the corresponding milk production, which could significantly impact the overall performance of your dairy farm. Therefore, it’s essential to try and minimize the number of animals in these categories.

“Nonproductive days can become a hidden cost on the dairy farm. By pinpointing and addressing this issue, you can reduce unnecessary feed costs and help boost overall farm performance.”

Investing time in proper management and targeted breeding practices can help reduce the length and number of nonproductive days. Here are a few strategies to consider:

Plan and implement a proactive health program. A robust health regimen can help prevent diseases and other health complications that could extend your animals’ nonproductive periods.
Optimize your herd’s breeding practices: This can help ensure that heifers can calve at the right time and help minimize unnecessary periods of unproductivity.
Monitor and adjust your herd’s nutritional intake: Proper nutrition is critical for the health and productivity of your dairy animals. By monitoring and changing their diet, you can help maximize their productive periods and minimize their nonproductive days.

Collaborate with Industry Experts

Collaborating with industry experts is an indispensable strategy for optimizing your dairy farm’s performance while reducing feed costs. This involves forming robust relationships with a network of professionals in the dairy industry, including feed suppliers, nutritionists, and veterinarians.

Form Strong Relationships with Feed Suppliers and Nutritionists
Working closely with feed suppliers and nutritionists can significantly enhance your dairy farm’s feed efficiency. These professionals can help you regularly review your ration strategies, allowing you to find cost-effective feed alternatives without compromising nutritional value. Not only can this lead to substantial savings on feed costs, but it also ensures your cows receive the optimal diet for their health and productivity.
Invest in Veterinary Support
Veterinary support is just as crucial to your farm’s performance. You’ll want to develop a comprehensive herd health plan with a professional veterinarian to prevent disease outbreaks and reproductive issues in your cows. A healthy and reproductive-efficient herd produces fewer nonproductive days, leading to optimized farm performance and reduced costs.
Use Farm Benchmarking
Lastly, farm benchmarking can be a powerful tool for performance improvement. By comparing your farm’s performance against industry benchmarks, you can pinpoint areas where your operation might fall behind, identify potential improvements, and measure the success of implemented changes over time.

The Bottom Line

Ultimately, the journey toward a productive and profitable dairy operation transcends the limitations of single-factor solutions. Integrating precisely formulated feed mixes, rigorous data analysis, and health-optimized herds is essential. Each of these elements must function in concert to achieve peak efficiency. In addition to these proactive strategies, cultivating strong relationships with industry experts is pivotal for long-term growth. Mastery of this comprehensive array of practices will ensure your survival and guarantee true long-term success in the demanding field of dairy farming. The outcome—a confluence of reduced feed costs, heightened efficiency, and increased profitability—provides dairy farmers an invaluable competitive advantage.

Calf Colostrum Versus Replacer – Which Is More Beneficial?

Friday, March 1st, 2024

Explore the debate between calf colostrum and replacer. Which provides more benefits for calf health and growth? Dive into the research with us.

In the dairy industry, the health and vitality of newborn calves are paramount, as they determine the future productivity of the herd. One of the critical decisions that dairy farmers face is whether to feed newborn calves natural colostrum or use a commercially available colostrum replacer. This article explores the benefits and drawbacks of each option, examining the ongoing debate within the dairy community to determine which is more beneficial for calf health and long-term productivity. In this article, we dive into both the benefits and drawbacks of each option. Our goal is clear: to provide you with the necessary information to make an informed decision, aligning not just with the current demands of your herd, but also considering their long-term productivity.

What’s the real value of natural colostrum?

Natural colostrum is invaluable for dairy calves, providing a multitude of benefits that are critical for their early development, health, and long-term productivity. Here’s an overview of the key values that natural colostrum delivers:

Immune System Support: Natural colostrum is rich in immunoglobulins (antibodies), especially IgG, IgA, and IgM. These antibodies are crucial for the passive transfer of immunity from the mother to the newborn calf, which is born with an immature immune system. This early immunity helps protect the calf from various infectious diseases during its first weeks of life.
Nutritional Content: Colostrum is much more nutrient-dense than regular milk. It contains higher levels of proteins, fats, vitamins, and minerals that are essential for the calf’s growth. This includes energy-rich components that help the newborn maintain body temperature and energy levels in the critical early hours and days post-birth.
Growth Factors: Colostrum contains growth factors such as insulin-like growth factor (IGF) and epidermal growth factor (EGF), which stimulate the development and maturation of the gut. This is vital for helping the calf to digest food more efficiently and absorb more nutrients, supporting better growth rates.
Enhanced Disease Resistance: Beyond the immediate passive immunity, the components of colostrum can enhance the calf’s own immune system over time, leading to improved disease resistance throughout its life.
Reduction in Mortality and Morbidity: Studies have shown that adequate colostrum intake is linked to lower mortality rates in calves. Calves that receive sufficient colostrum are more likely to grow into healthy adults, with fewer instances of diseases like diarrhea and respiratory infections.
Long-Term Productivity: Calves that are fed adequate amounts of high-quality natural colostrum tend to have better overall health and higher productivity later in life. This includes improved growth rates and, for female calves, better future milk production when they become lactating cows.

Given these extensive benefits, it’s clear that natural colostrum is crucial for maximizing the health, welfare, and economic returns of dairy calves. Ensuring that calves receive an adequate amount of high-quality colostrum immediately after birth is one of the most effective strategies to set the foundation for their future success.

How effective are commercially available colostrum replacers?

Commercially available colostrum replacers can be quite effective for dairy calves, especially when high-quality natural colostrum is not available or when there is a risk of transmitting diseases from the cow to the calf. These products are designed to mimic the nutritional and immunological properties of natural colostrum and provide several key benefits:

Effectiveness of Colostrum Replacers

Immunoglobulin Content: High-quality colostrum replacers are formulated to contain a specific amount of immunoglobulins, particularly IgG, which is crucial for establishing passive immunity in newborn calves. The effectiveness largely depends on the concentration and absorbability of these immunoglobulins.
Nutrient Density: Replacers are also rich in nutrients, including proteins, fats, vitamins, and minerals, ensuring that calves receive the essential nutrients they need right after birth.
Disease Control: One of the significant advantages of using colostrum replacers is their ability to prevent the transmission of infectious diseases such as Johne’s disease, Mycoplasma, BVD, and Leptospirosis, which can be passed through natural colostrum.
Consistency and Reliability: Colostrum replacers offer consistency in nutrient and antibody levels, providing a reliable alternative when the quality or quantity of natural colostrum is insufficient.

Limitations and Considerations

While colostrum replacers can be highly effective, they also come with some limitations:

Cost: High-quality colostrum replacers can be more expensive than natural colostrum, making them a significant cost factor for some farms.
Variability in Quality: Not all colostrum replacers are created equal. The effectiveness of different products can vary based on the source and concentration of immunoglobulins and other nutrients.
Absorption Rates: The rate at which immunoglobulins are absorbed from replacers can be lower than that from natural colostrum. This makes it critical to administer replacers properly and within a specific time frame after birth.

Best Practices for Use

For optimal effectiveness, it’s important that colostrum replacers are administered correctly:

Timing: Calves should receive colostrum replacers within the first 2 hours of life to maximize the absorption of immunoglobulins.
Dosage: Follow the manufacturer’s recommended dosage to ensure that calves receive enough immunoglobulins to establish passive immunity.
Handling: Proper mixing and handling are crucial to maintain the integrity of the replacer.

Colostrum replacers can be a valuable tool in calf rearing, especially under conditions where the quality or availability of natural colostrum is compromised, or there is a need to avoid disease transmission. When selected and used correctly, high-quality colostrum replacers can effectively substitute for natural colostrum, providing the essential immunity and nutrients that newborn calves need to start a healthy life.

The milk replacer’s composition stays constant if it’s prepared consistently using the correct amount of water and powder.
There is no risk of vertical transmission of diseases, which is possible with raw milk.
This may sound odd because whole milk is produced by the cow, but milk replacer is easier to use because with whole milk you are always dependent on milking times,
The lower fat content makes it easier for calves’ roughage uptake
The added health formula in calf milk replacer contributes to optimum intestinal and airway health, which in turn leads to higher growth rates proven in trials on CAIR and the IMAGRO health concept.

Choosing Wisely: Factors in Selecting Calf Colostrum or Replacer

When deciding between natural colostrum and a colostrum replacer, there are several key factors to consider.

First, the origin and intensity of disease presence in the herd plays a role. For instance, research demonstrates that calves fed colostrum replacer at birth are less likely to be infected with Mycobacterium avium subsp paratuberculosis compared to those fed colostrum, in herds with Johne’s disease. Hence, if this disease is a concern in your herd, choosing a good-quality colostrum replacer might be a safer option.

Secondly, the availability and perceived quality of maternal colostrum are important factors. If maternal colostrum is unavailable, or its quality and quantity cannot be guaranteed, a product like OptiPrime Colostrum Replacer, which contains globulin proteins derived from bovine colostrum, might be a worthy choice. Remember, feedings of poor or moderate quality maternal colostrum may not provide calves with the adequate level of antibodies for optimal health. Colostrum replacers can help bridge this gap as their contents are more regulated and they contain more immunoglobulin than supplements.

Also, the practicality of use and the need for obtaining passive immunity swiftly might affect your decision. Colostrum replacers can be measured accurately and are easy to mix, enabling a quicker access to antibodies for the calf, especially vital in the crucial first few hours after birth.

Lastly, several studies have investigated the impact of different additives like trypsin inhibitors and egg proteins in colostrum supplements on dairy calves. These additives may enhance the functional value of the colostrum and be beneficial for certain health conditions or management goals.

All in all, there is no blanket solution for every situation. To find the most suitable option, a thorough understanding of the calf’s specific needs, the herd health status and the practicality within your farming operations is essential.

Meeting Nutritional Needs: How Calf Colostrum and Replacer Stack Up

Let’s dive deeper into how calf colostrum and colostrum replacers meet the nutritional needs of newborn calves. Colostrum, nature’s first milk, is packed with essential nutrients, antibodies, and growth factors that not only fortify calf immunity but also support their early growth and development. Its unique biological makeup makes colostrum an absolutely indispensable start for every newborn calf.

However, when the quality or quantity of colostrum is not adequate, using a good quality commercially available colostrum replacer becomes crucial. They are designed to mimic the nutrient composition and immune-boosting properties of natural colostrum.

According to research studies, colostrum replacers can potentially offer similar or even better nutritional values in certain cases compared to natural colostrum. A suitable example would be a study that observed 497 calves over a period of 54 months and concluded that there were no noticeable differences in various parameters between calves fed either maternal colostrum or a serum-based colostrum replacer at birth.

Another key finding in research is that calves fed colostrum replacers at birth were found to be less likely to get infected with Mycobacterium avium subsp paratuberculosis – a causal agent of Johne’s disease, as compared to those fed with natural colostrum. This suggests that colostrum replacers might offer certain health protective advantages.

Additionally, one should acknowledge that replacers contain more immunoglobulin than supplement products – often supplying more antibodies than poor or moderate quality colostrum. In an experiment comparing colostrum and serum-based colostrum replacer, no differences were observed in analytical measures such as IgG levels, efficiency of IgG absorption, the incidence of scours, or growth rates.

Furthermore, certain replacers come enriched with different beneficial additives like trypsin inhibitors and egg proteins, thereby offering enhanced nutritional value and improved digestion in calves.

In conclusion, while natural colostrum remains the gold standard, colostrum replacers when wisely chosen, based on quality, nutrient content, and specific needs of the calf, can do an excellent job in delivering nutritional needs and boosting immunity of neonatal calves.

Can one truly replace the other without any significant implications?

You might be asking, can calf colostrum and its commercial substitute be swapped without causing any major impacts? The research we analyzed offers an illuminating response to that question. A myriad of scientific investigations, including 26 research trials involving approximately 90 assorted treatments, has delved into the implications of substituting natural colostrum with commercial replacers or supplements.

For example, one prominent study followed 497 calves from birth to 54 months old. When these calves were fed with either maternal colostrum or serum-based colostrum replacer at birth, no discernable differences were observed across several parameters. These statistics extend to rates of IgG absorption, efficiency, the incident of scours, and overall growth, shining a positive light on colostrum replacers.

Another important experiment compared calves fed colostrum and those given a serum-based colostrum replacer. Again, no major differences were observed in IgG levels or the rate of growth amongst the calves, further substantiating the effectiveness of colostrum replacers.

Amongst calves born in herds with Johne’s disease, those fed colostrum replacers at birth showed decreased susceptibility to infections, specifically from Mycobacterium avium subsp paratuberculosis, when compared to calves fed traditional colostrum. A stark contrast that indicates the disease-fighting potential in colostrum replacers.

The Bottom Line

At the end of the day, you, the calf rearing professional, have at your disposal a viable solution in colostrum replacers. They become an indispensable aid when natural colostrum is of subpar quality or simply not enough in quantity, or in scenarios that necessitate dodging disease transmission. The trick lies in making the right selection and mastering the correct usage. Once this is achieved, top-notch colostrum replacers can step in for natural colostrum successfully, delivering the vital immunity boost and nutrients newborn calves require to embark on a healthy life journey.

Summary: The dairy industry is crucial for the health and productivity of newborn calves, which determine the herd’s future. The choice between natural colostrum or commercially available colostrum replacers is essential for calf health and long-term productivity. Natural colostrum offers immune system support, nutritional content, growth factors, disease resistance, reduced mortality, and better overall health. Colostrum is more nutrient-dense than regular milk, containing higher levels of proteins, fats, vitamins, and minerals essential for calf growth. Adequate colostrum intake is linked to lower mortality rates in calves, making them more likely to grow into healthy adults with fewer diseases. Long-term productivity is also improved by providing high-quality natural colostrum, including improved growth rates and better future milk production for female calves. Over 95% of calves fed natural colostrum survive to weaning, with a 40% lower incidence of diarrhea in the first two weeks of life.

NUTRITION and PREGNANCY. The Conception Connection.

· Comments (0)

Wednesday, May 20th, 2015

A pregnancy is a pregnancy, right? Or is it? Where do you place your dairy pregnancy focus? On cows that are already pregnant? On early lactation animals? Is your biggest concern that of matching energy requirements to maximize milk production? Is your nutrition program defeating your reproduction rate? We need to go back to the beginning of the dairy profitability story and consider what happens between the breeding and a successful pregnancy.

The Incredible Conundrum

When we talk about breeding dairy cattle, the standard benchmark is two breedings to achieve one pregnancy. For me, baseball is the only place where achieving 50% makes you an All Star. The dairy industry needs to step up to the plate. Let’s take every opportunity to change the breeding rate to a 1to1 ratio. If that were possible, it could save both time and money while increasing the number of pregnancies in dairy herds.

What factors – that are in your control – could raise your herd pregnancy success rate? We all nod in agreement that catching heats and preventing exposure to pathogens are ways to increase our success rate. Are we nodding in agreement and taking action? Or are we nodding off? And what about nutrition?

The Proposition: Nutrition has a significant role in maintaining pregnancy immediately following conception.

Causes of Early Embryonic Loss

Researchers in Minnesota, South Dakota, and Wyoming saw rises in early embryonic loss if either of the next two situations occurred:

A significant decline in energy intake.
Moving from stored feed to pasture.

Nutrition Indicators that Signal Problems Getting Cows Pregnant

Limitations. Every dairy farm has to deal with them. Here are four that affect pregnancy rates.

There are cows not showing heats and anestrus in early lactation
Energy deficiency is the first limiting nutrient in your herd if your cows are not cycling.
You or your adviser have identified a deficiency of minerals and vitamins in your ration
You or your adviser have identified an excess of protein in your ration

It’s time to do something about eliminating these limiting factors.

The Sperm in the Uterus. Take Care of It!

In cattle, the fetus does not immediately become attached to the uterus endometrium. This means that it spends several days in the lumen of the uterus. During this time, uterine secretions nourish and provide the enzymes, hormones and other metabolic factors that the fetus needs for development. These nutrients are comprised of glucose, fructose, some triglycerides and amino acids. Glucose is the primary source of energy for the developing fetus, and similar to pre-breeding, energy is probably the first limiting nutrient for fetus growth and development.

Supplement with Methionine to Prevent Pregnancy Loss

One way to improve both milk production and reproduction is to supplement rations with methionine for a lysine to methionine ratio (% of MP) of 2.8 to 1.

Researchers fed a methionine-supplemented diet to early lactation cows with 2,500 grams of metabolizable protein (MP)—6.9% of MP as lysine and 2.3% of MP as methionine. The methionine-supplemented cows had slightly less pregnancy loss following breeding than cows fed the same diet with no supplemental methionine (1.9% of MP).

How to Optimize Pregnancy Maintenance

Certain amino acids give rise to glucose as well as glycerol levels. Optimizing the amounts of and the digestion of starch is the best way to increase the glucose supply to the dairy cow.

Methionine, lysine, and histidine are considered the first three limiting amino acids in milk production and milk component levels. They also increase in uterine secretion as the embryo elongates and prepares for implantation in the uterus endometrium.

Wisconsin researchers report an increase of 14.4% for lysine, 12.4% for methionine and 11.5% for histidine in the pregnant uterus near the time of implantation compared to a non-pregnant uterus. Methionine is of particular interest in the early fetus stage because of its role in lipid metabolism and gene expression.

Current studies using DHA in lactating cows are aimed at enhancing the quality of the uterine epithelium, modifying and attenuating the release of prostaglandin F-2a and thus ensuring a higher pregnancy rate resulting from better maternal recognition of pregnancy and subsequent maintenance of pregnancy (Read more: 8 Things You MUST Know About The BLV Virus)

Get Ready to Formulate a Preconception Diet

We are well-prepared to monitor the nutrition of the pregnant animal, and to meet the needs of the milking cow, but too often we are overlooking the importance of the preconception diet!

Long before that heifer/cow is safely in calf, what she eats matters. In fact, the right preconception diet can not only fuel fertility, but can also ensure that you get a healthier calf on board.

Not sure how to turn your dairy diet into one that’s beneficial for preconception and pregnancy? Follow these five easy steps:

Commit to change. The first step to overhauling your preconception nutrition is to know exactly what you’re committing to and why. The why? Well, that’s pretty clear. You want to make the healthiest calf possible, as quickly as possible. Your goal is to improve your current pregnancy success rate.
Identify WHO needs to Change? So you’re willing to make changes. It is important to know what change will produce the targeted result. Depending on what you have learned from an analysis of your records, you may also need to reconsider “who” is best suited to take responsibility. A veterinarian, nutritionist or feed consultant – or all three may have valuable input in overcoming pregnancy maintenance challenges.
Identify WHAT needs to Change? Even the most conscientious dairy manager may find themselves second guessing when it comes to formulating a preconception diet. Trying to scale down weight? (Extra pounds can decrease fertility.) Trying to gain weight (too thin may be having an adverse impact). Then you’ll probably have to work on quantity and quality.
Get Ready to Pop a Prenatal Vitamin. No human preconception diet is complete without a prenatal supplement that’s packed with folic acid and other essential baby-making nutrients. What parallel are you using in enhancing the conditions in the uterus. Think of it as health insurance for your future calf.
More feed. More often. This isn’t the time for a hit or miss access to the feed bunk. You may want to consider trading up to the six meal solution that human pre-natal consultants advise when a woman is trying to conceive. Dairy cows should consume frequent, small meals spread out over the day. To achieve this, we need to ensure they have good access to their ration throughout the day. This can be accomplished through the frequent delivery of feed, frequent feed push-up, and by providing sufficient space at the feed bunk. Extensive sorting of feed should be avoided.

It’s a balancing act. Any one of these five variables could be affecting your success. And this isn’t the entire list by any means.

The Bullvine Bottom Line – “Better Endings Start Even Before the Beginning!”

Successful dairy operations depend on conception. It makes sense to look at nutrition that impacts that status. Despite many advances in dairy cattle breeding, there are still challenges associated with starting a successful pregnancy. Take action now! The preconception diet can have a surprisingly significant impact. Success has to mean better than 50%.

FROM ALFALFA TO OMEGA – YOU are What THEY Eat!

· Comments (0)

Monday, May 11th, 2015

It is difficult to have a diet that is rich in all the components needed for healthy living. Many, including myself, turn to supplements to make up for what’s lacking in our diets. Modern food producers are looking for new ways to add nutrients to food products. This value-added is taking interesting turns in the milk production industry.

Adding supplements to food is not a new idea.

For almost 100 years, Vitamin D has been added to commercial cow’s milk in response to the rise in malnourished children and adults with insufficient amounts of this essential nutrient in their diets. Today another nutritional shortcoming of the Western diet has been identified. Despite having plentiful amounts of fat, the Western diet is lacking in a specific group of fatty acids called omega-3s, touted for their benefits to heart and brain health. Food manufacturers have started fortifying commonly consumed foods, including breads, cereals, and eggs, with these essential fatty acids.

The Benefits of DHA

One crucial fatty acid, is the omega-3 derivative, docosahexaenoic acid (DHA).

The benefits of consuming DHA omega-3 are

Children:

Enhanced cognitive function and learning ability in children
Benefits for children with attention deficit and hyperactivity disorder (ADHD).

Adults:

Lowering the risk of developing cardiovascular and Alzheimer’s diseases
Lessening severity of depression.

The diet of mothers affects the content of DHA in breast milk. Adequate supplies of DHA are required for infant development.

Making up for the Shortfall

Supplementing the diets of food producing livestock with DHA-rich microalgae sources has successfully produced DHA-enriched meat and milk from livestock such as pigs and poultry. Now focus has turned to ruminants and the production of DHA-enriched food.

Cow’s milk is picking up Omega-3s in more ways than one

Milk produced by today’s dairy cattle has less omega-3 fatty acids than in the past when all livestock was pasture based. For this reason, researchers are looking to add the Omega 3s to dairy cattle diets with the intent of raising the proportion of healthy fats in the milk produced.

Studies Are Reporting Significant Results

Studies in 2008 (Boeckaert et al.) and 2012 (Stamy et al.) have examined the effects of feeding algal meal, high in DHA, on feed intake, enteric methane production, and milk parameters. It has been demonstrated that feeding algal meal may inhibit voluntary dry matter intake and reduce milk fat concentrations (Moate et al., 2013).

Results from a Trial Study in Italy

In a recent trial in Italy, researchers examined the effects of feeding algal meal (Algae S^TM) on milk production and milk composition of lactating dairy cows. Maurice Boland (Alltech) reports as follows:

“The study was carried out with 36 Italian Friesian dairy cows in their average-late stage of lactation. Cows were allocated into two homogenous groups of 18 animals each, where the treated group received the supplementation (6 g/kg DMI) of the test product for 84 consecutive days mixed into one component of the TMR (corn meal), while the control group had received the same amount of corn meal without a test product.

The results of the study showed that the treatment with algal meal did not change the body condition scores and live weight tended to be a little higher for those cows. . Specifically “Milk protein content and production, lactose content and production, urea and somatic cell count were unaffected. The algal meal (Algae S^TM) significantly affected the milk fatty acid profile, increasing milk DHA (% of FA) from 0 to 0.37%. The researchers concluded that algal meal fed in a TMR to dairy cows enriched milk with beneficial DHA and increased conjugated linoleic acid. Milk yield increased; while milk fat and fat production declined without significant change in four percent fat corrected milk.”

DHA inclusion in the diet could also increase reproductive efficiency in the herd.

Another happily anticipated side effect is that, in addition to the benefits for animal and human health, DHA could help bovine reproduction. Maurice P. Boland is the research director for Alltech. He reports that current studies using DHA in lactating cows are aimed at enhancing the quality of the uterine epithelium that could modify and attenuate the release of prostaglandin F-2a. This could ensure a higher pregnancy rate because of the better maternal recognition of pregnancy and the subsequent maintenance of pregnancy. The implications are huge for the dairy industry. Better reproduction starts the process off better, and laboratory studies are confirming that there could also be benefits in the post-pregnancy health of dairy cattle that receive DHA.

DHA Improves Immune Function of Dairy Cattle

After dairy cows deliver their calves, several immune functions — such as white blood cell proliferation and production of disease-fighting antibodies — are depressed. Recognizing this, the development of new feeding strategies in which the fatty acid composition of the diet is manipulated in order to prevent immune suppression after calving should contribute to decreased infection and disease in dairy cows. Preliminary results in the laboratory indicate that ALA (alpha-linolenic acid) and EPA (eicosapentaenoic acid) can reduce immune stress as shown by decreased TNF-α (tumor necrosis factor-a) production in cultured blood cells from cows.

If these results can be repeated in the field, then strategic supplementation of early-lactation dairy cows with selected omega-3 PUFA may lead to improved health and reproductive efficiency. Such improvements could represent an annual savings of over $2 billion dollars through improved reproductive efficiency and reduced veterinary costs for treatment of postpartum metabolic disorders. These savings would undoubtedly improve the sustainability and profitability of U.S. dairy operations.

The Bullvine Bottom Line

One hundred years ago adding Vitamin D to milk had a profound impact on human nutrition. Modern dairy research is taking strides in further increasing the nutritional value of milk. As that process builds, much is being learned about making a positive contribution to the health, reproduction and performance of dairy cattle. It’s a winning formula that starts at the farm feed bunk and continues to enhance nutrition beyond the kitchen table.

Silage Inoculants: Are They An Investment, Insurance or Intervention?

· Comments (0)

Thursday, September 4th, 2014

Sometimes it is challenging to be a dairy farmer. When it comes to producing high quality dairy feed, the results can be affected by everything from weather, to timing, to handling and storage. One seemingly small misstep can turn a perfectly good crop into something you can’t or shouldn’t put in front of your cows. Which brings us to silage inoculants and how they may be used to maintain and improve feed.

To Inoculate or Not to Inoculate? That is the Question.

First off let’s remember that feed accounts for 55-60% of the cost of running a dairy operation. Providing high quality feed is crucial for success. Today your strategy must go beyond deciding “if” you should use an inoculant or whether you should only use it only on certain forages. Advisors are clear. “A quality silage inoculant should be used on all ensiled feeds.” A quality silage inoculant will quickly guide the fermentation process towards the production of lactic acid to drop the pH of the forage. A quality silage inoculant will also provide some measure of insurance against sub-optimal harvesting, chopping, filling, packing, and covering conditions. An inoculant will not make bad forage good, but it will maintain the quality of the forage better than uninoculated silage. Forage is the foundation of a dairy cow’s diet. Better quality forage will allow animals to perform better. Better quality silage will prevent loss of silage due to shrinking. Don’t throw 4% of your biggest expense away. It also will help you secure that your storage inventory will last you until the next harvest. Better quality silage means less need to purchase high energy, and high protein feeds. Thus, the short answer is “yes” to inoculants, in order to get improved performance at a lower cost.

Taking the Fear out of Fermentation

“Fear” may seem like an extreme choice of words because after all fermentation is simply the process where bacteria use sugars to form organic acids that lower pH and preserve the forage. Simple yes. But it’s a precarious balancing act that has water, time, oxygen and other variables working to upset the feed cart. Getting the crop harvested and ensiled at its highest nutrient level is step one. It’s at this point that all oxygen must be eliminated so that the bacteria can get to work. Any slip ups here and there will be nutrient and dry matter losses. The fact that the silage is out of sight means it could easily slip off your radar. Meanwhile, there are micro-organisms .. both good and bad … and what you want is to have sufficiently large quantities of the right bacteria dominating the fermentation. That’s where a silage inoculant can be a useful tool.

The Next Important Question. “Which Inoculant to choose?”

First of all you have to establish what you need? When you have decided whether you need a fermentation aid or a spoilage inhibitor, then you must make sure your choice is one that is backed by research. There are significant genetic differences between LAB (lactic acid bacteria) species and strains. It is difficult to compare products because not all products are equally effective. Your provider should be able to support claims of reduced dry matter losses or improved feed efficiency. You must pick based on the type of silage (corn silage vs. haylage). Not all inoculants are created equal. Seek out the answers to your quality control questions.

Okay, But Will It Actually Work?

All is lost if you use an inoculant that doesn’t work. You must make sure that you have the right bacteria that will grow rapidly in the pH range of the forage they are growing in and produce lactic acid. Here is the point where understanding silage inoculants becomes a science lesson. If this isn’t an area you readily understand, it might be best to seek out he assistance of a specialist, nutritionist or feed consultant. At the most basic level, you want the bacteria to be live and vigorous and the count of the bacteria (CFU) to be at least 100,000 CFU/g.

Population of Lactic Acid Bacteria Applied to the Forage

The population of LAB applied should be at least 10% greater than the natural bacteria that are on the forage. Most inoculants are applied at a rate of 100,000 cells per g (CFU/g) of silage, but applying L. buchneri at 400,000 to 600,000 CFU/g may further improve its efficacy provided it is addressing the problem in your silage. Inoculation at rates that are even just 1% less than natural populations can result in these additives having little impact on silage quality (Muck 1989). Consequently, proper application rates are critical to deriving value from inoculants.

Nature of the Forage Being Ensiled

The forage should have sufficient substrates (e.g. water soluble carbohydrates) and optimum moisture for fermentation (Muck 1989). Consequently, stage of growth of forage at the time of ensiling impacts the value of inoculants.

Are Enzymes Value Added?

In an effort to make more plant sugars available to the bacteria, enzymes can be added to a quality inoculant and is particularly helpful if the plant sugar content of the silage is low. Adding enzymes that work is more costly but can increase dry matter recovery and dry matter digestibility. This is a case where you have to trust that “you get what you pay for.”

Doing your homework and getting advice from knowledgeable feed consultants will certainly help with informed decision making in this area.

Good Inoculants Have Good Data or “Buyer Beware.”

Another key is to make sure the inoculant you are going to use has good research documenting its’ efficacy. Multiple university research trails over different years and growing conditions on the forage type you are inoculating is highly desirable. Research should support the efficacy of the product at the application rate it is being sold at and should validate any and all claims made for the product. Be very cautious VOUR using only “testimonials.”

Don’t buy an inoculant only on price. Often, you get what you pay for. Quality bacteria and enzymes cost more money to manufacture than cheap bacterial. You are better off not spending any money on an inoculant than spending a small amount of money on an unproven or low-quality inoculant. Find the inoculants that all have the technology and research you want and then look at the price.

The Economics of Silage Inoculants from Feed Bunk to the Bank

You are ready to accept that silage inoculants are insurance but are they an investment that either saves the silage of increases profit or both. Results of many research studies show that inoculants improve DM intake and milk production by 4 to 5% for grass, corn and alfalfa silages. Assuming that inoculants improved DM recovery by 1.25 to 2.5% and milk production by 0.1 L per cow per day, net returns were estimated at $5.76 and $14.40 per tonne of corn and alfalfa silage, respectively. (Bolsen et al.)

Worth the Money or Not?

Will you get your money back from using inoculants? It is hard to see subtle changes in animal performance. Measuring reduced dry matter losses or silage shrink. If the bottom line shows improved production is it due to the inoculants or should some other management factor get the credit. Fortunately, university research is providing data showing the successes of inoculant products.

The cost of silage additives can range from 25 cents a treated ton to almost $2 per treated ton. Paying 30 cents a ton on a product that does nothing to improve fermentation is a bigger waste of money than spending 30 cents too much on a product that does improve the value of your feed. Evaluate additives to be sure the product can lower pH and preserve the silage.

Where Does that Leave Your Inoculant Knowledge?

To make good quality silage, one must have an appreciation of the plant and microbial and environmental factors that influence silage fermentation, all of which ultimately dictate the nutrient value and quality of silage.

Advancements in inoculant science have produced inoculants that can improve the aerobic stability of silage and in the case of 3rd-generation inoculants, even the digestibility of fibre. Fourth-generation inoculants are presently under development with a focus on delivering silage with probiotic properties that could deliver health benefits to the animal.

All of the preceding factors must be considered as an integrated package. Neglect of any one component can lead to a breakdown in the forage preservation process. Silage inoculants can facilitate the ensiling process, but they are not a replacement for paying attention to the fundamental factors that are the keys to making good quality silage.

Proper Application Is Key

Make sure that you have the ability and knowledge to properly apply silage inoculants according to manufacturer’s recommendations combined with sound ensiling best practices. Remember the application of a silage inoculant will not overcome the effects of poor silage management or poor weather conditions. Three important keys to good silage fermentation are harvesting at the correct moisture and chop length, quick and adequate packing, and sealing immediately after filling. If all of these are well handled, commercial inoculants can be a valuable tool in silage systems.

The Bullvine Bottom Line

The ecology of ensiling is exceedingly complicated, however, since forages represent a large proportion of the feed costs of dairy production, the generation of high-quality silage is especially important in achieving profitability. At the end of the day, properly selected, applied and managed silage inoculants can make three significant contributions: insurance for obtaining quality forage, an intervention to prevent negative organisms in harvested forage and an investment to increase DM intake and milk production.

Dairy Nutrition. The K.I.S.S. of Wealth!

· Comments (0)

Thursday, August 22nd, 2013

Thinking of our personal health and hearing the term ‘nutrition’, you might be motivated to eat more vegetables. That’s simple and we all like the K.I.S.S. (keep it sweet and simple) principle.

Dairy Breeding is Simple Too

All you have to do is pick the right dairy breed, the right dairy genetics and, at least occasionally, manage to have Mother Nature and the marketplace somewhat on your side and it follows that you will produce buckets of milk and be the proud owner of a sustainable dairy business. And that’s exactly why we more often face the O.U.C.H. syndrome – Overworked Underproducing Cattle Herds. Why is it that, with all the technology, science and passion at our fingertips, we are missing something?

They Are What They Eat!

Cows eat every day. Cows are milked every day. It would seem to follow that those simple, daily actions could be the key to simplifying our dairy success. Perhaps dairy breeders are missing opportunities and should seek expert help from nutrition consultants. After all, meeting production, herd health and economic goals directly affects the profitability of every dairy herd. The tricky part is that every dairy operation has unique issues that must be considered as part of the nutrition solution.

Why Bother With a Nutrition Consultant?

An effective nutrition consultant will investigate and analyze all the issues impacting your cows and thus impacting your success. The Bullvine went to Dr. Scott Bascom to get some insight on the value of working with a nutrition consultant. Dr. Bascom is the Director of Technical Services at Agri-Nutrition Consulting, Inc. (ANC) (Read more articles about animal nutrition by Dr. Bascom). He confirms “nutrition consultants can design a customized feeding program to meet their client’s specific goals and make the best use of the resources they have on the farm, and are skilled at feeding cows, heifers, and dry cows in a manner that will keep them healthy and highly productive.” However his years of experience starting at college have given him a wider viewpoint. While in college he attended a lecture given by Dr. Paul Chandler. Chandler shared, “There are many reasons beyond economics that a nutritional consultant provides value.” He feels that one of the best resources that a good nutrition consultant can develop is in maximizing the human side. “You have days when you are also a financial advisor, psychologist, marriage counselor and a loyal friend.” He continues, “At the time I didn’t comprehend what Dr. Chandler meant but now I recognize that he was telling us we would have to go beyond our skill in nutrition to develop a high level of trust with our clients if we were going to be successful.”

Not Just a Quick Fix. And BORING is good too!

The very nature of dairy breeding has conditioned breeders to the fact that any process we implement or change we make must be undertaken not as a short term fix but with a view to profitability for many years to come. Changes are both feared and welcomed. Feared because they’re never easy. Welcomed because of the potential for improvement. Dr. Bascom has a somewhat unconventional view of change as it relates to nutrition. “With my clients I am striving for BORING. I want a boring ration that never changes because we feed the same thing all the time. I want cows that are BORING because they are healthy, comfortable and get bred in a timely fashion. I want my herd visits to be BORING because we have no major issue to consider. My point is the goal is to get our clients to a place where we are meeting our goals and rarely need to make any big changes. At this point we make very minor adjustments when we need to make a change. The cows are happy, the producer is happy, and I am happy.”

From the Bunker to the Bank!

We spend research dollars to identify a cow’s genes to the smallest snippet. We spend millions of dollars on the cow with the best dairy conformation. But we can’t agree on what to feed her at the bunker. Dr. Bascom feels that dairy nutrition is economically imperative. “The producer that isn’t working with a nutritionist has a lot as risk financially. The value of feed fed to a lactating cow can be $8 or more per day. For a 100 cow herd the value of feed fed in a year is well over $250,000! With feed costs so high, optimizing income over feed cost becomes critical.” He backs up the statistics with personal experience. “When ANC picks up a new client that was not using a nutritional consultant prior to me, it is not unusual for us to increase income over feed cost by $0.25/cow/day. This adds up to a significant increased annual income.”

Keep Your Money Growing Just for You

“Another significant reason to work with a nutritional consultant is that they can bring new ideas to the farm. Consultants are exposed to a diverse range of information including what we learn from other clients, trade shows, continuing education, and other people in our support network. Part of our job as an advisor is to filter through all this information and bring back to our clients what is most applicable to their situation?”

How to Increase Milk Production

As I write this, I begin to see that the practice of nutrition is like the practice of medicine. Being blessed with both an animal nutritionist and a medical doctor in the family, it is increasingly clear to me that the really good practitioners in either field are the ones who not only understand the science but can put it into practice. Dr. Bascom readily is a storehouse of working examples derived from dairy nutrition consulting. “Let’s talk about increasing income over feed cost. Often this includes increasing milk production. However, too often we can fall into the trap of pushing for higher milk production in a way that isn’t profitable. When we decide that higher milk production is the key to increasing income over feed cost then we look at forage quality, cow comfort, facilities, and a variety of management factors to decide how to reach this goal. The answer is different on every farm. For example if I have a client that has average days in milk of 250 days then we are not going to increase milk production until we improve reproduction. On the other hand, a client that is overstocking their facilities might experience an immediate increase in milk per cow and total milk shipped by culling out some of their bottom end cows thus improving cow comfort for the rest of the herd.”

What Does Quality Cost?

In polling dairy breeders who do not use consultants, the number one reason given is that either the consultant or the feed program will be too expensive. Dr. Bascom appreciates the opportunity to answer this concern. “Again, we start by talking about income over feed cost! Sometimes decreasing out –of-pocket costs drops income over feed cost! The answer to this question is to look for ways to make the best use of the resources available on the farm. We ask questions like, are we getting the most value out of the forages we are feeding? Are we feeding commodities that are competitively priced? Are we wasting feed?” Too often we measure financial success by decreased input dollars. Sometimes we have to spend a little to make more. A key learning to internalize is that you can waste money just as easily on excessive quality as you can on deficient quality. Optimum quality is the goal.

Let’s Ruminate on Components!

“In most cases increasing components will increase income over feed cost. The exception would be in markets that don’t pay premiums for high component milk. Low components could be an indication of cow health issues. So fat and protein tests are something I watch closely.

The first step in high component milk is about feeding a healthy rumen. Forage quality is paramount. We need high quality forages to optimize rumen health. So the first step is to make sure forage quality is optimum. We also balance carbohydrates and degradable protein to encourage rumen health. The rumen bugs produce very high quality protein that drives both milk yield and components. After we have designed a diet for optimum rumen health and to maximize the production of high quality protein by the rumen then we look at additives. These would include bypass protein sources and rumen protected amino acids.”

Beyond the Basics to Practical and Personal

One of the most rewarding aspects of being connected to the dairy industry is hearing stories such as the ones Dr. Bascom shared with us. “Years ago I worked with a dairyman in the southeastern part of the US that told me I got more milk for him than anyone else. I was only able to get his cows to 50 lbs. of milk but he was close to 30 when we started. This won’t get me on the cover of a major dairy magazine but to him it was a really big deal.” Of course there are times ANC’s client’s success has meant rising to a challenge. “One of my ANC clients challenged me to feed as much forage as we could feed to his cows and maintain healthy cows, production at 75 lbs. of milk, and high components. We were able to get the diet up to 82% forage as a percent of dry matter. We maintained milk at 75 lbs., fat test over 4.0%, protein at 3.3%, cut purchased feed costs, cow health improved, and reproductive performance improved. I didn’t think we could take the forage to this level without losing milk!” Every client has different goals, says Bascom. “Several years ago I started working with a new client that markets embryos. The goals were to maintain fat test at 4.0%, protein at 3.4%, and cut purchased feed cost. We made adjustments to the diet to feed more of their homegrown forages to cut purchased feed cost. We also added a liquid feed to the ration and made some adjustments in how the TMR was mixed. Not only did we save money but the cows came up in both protein and fat test. This put more money in the milk check and also made more cows in the herd eligible for the foreign embryo market.”

ROF is Good. Return on Relationship (ROR) is Great.

It doesn’t matter what facet of the dairy industry you work in, you’re going to find passionate people. Dr. Bascom is one of them. “I love cows,” says this ANC consultant and adds, “Following a career in nutrition allows me to be around cows and people who love cows.” And that is a key motivator for him. “The cow success stories are rewarding but perhaps the most rewarding experiences are the people success stories. I have celebrated weddings and the birth of children with my clients. I have watched their children grow-up and find their way into the dairy operation. I have cried tears at the loss of their loved ones. These experiences are just as rewarding as celebrating high rolling herd averages, the sale of bulls into AI, All-American nominations, and high classification scores. This is very much a people business and it is so rewarding to gain the trust of my clients in a way that they want to share good times and the hard times in life with me.”

The Bullvine Bottom Line

We can all identify with the passion that makes a career in dairying the focus of our daily lives. However, we can’t let rose colored glasses cause us to limit our dairy herd success. Dairy nutrition consultants help us to investigate and discover ways to overcome unnecessary or unseen obstacles. So that leaves the Simple Question: “Why bother with nutrition consultants?” And leads to the Simple Answer: “You can’t afford not to.”
