Ensuring bull fertility after a harsh winter

Submitted by tile on Wed, 04/02/2025 - 07:06

They are big, they are hard to handle, they can be hard to move, they are hard on each other, they are hard on equipment, they are hard on you and hard on the help. Outside of putting them to work 60–90 days out of the year, most producers wish they didn’t have to own one, much less a group of them.

Yes, we are talking about bulls and their antics! Most often, producers put their bulls to work and then turn them out into the farthest-away pasture and mostly forget about them. Out of sight, out of mind! Have you looked at your bulls lately?

Given the winter weather most of the country has seen this year, there may be some issues that bulls have never had to deal with — or producers either. Most producers in the northern climates are used to managing through severe cold, wind and snow, but this year there could be issues that there normally wouldn’t be, and maybe more so in the south and southeast due to the cold, snow and ice. Cold stress, frostbite, poor body condition and injury could have occurred in any and every part of the country this year.

With record or near-record prices paid for calves this fall, bred heifers this fall and winter, and cow/calf and heifer pairs now, it is crucial to get the females in the herd bred; and bulls are at least half of the equation to making it happen.

Cold stress and frostbite

Cold stress occurs when body temperatures drop because animals can’t keep themselves warm. During these times, the body tries to stay warm by shivering to generate body heat, which burns a lot of calories. If the available feed isn’t adequate to meet the increased needs, a big loss of body condition can occur if the cold extends for a prolonged period. Also, in severe cold, wet and windy conditions, frostbite is a danger.

What is frostbite? It is a condition that occurs when body tissues freeze due to prolonged exposure to extremely cold temps. Frostbite mostly occurs on the extremities of the body that normally see less blood flow. In young cattle, frostbite may be on ears and feet. Early symptoms of frostbite are swelling or edema, followed by the affected parts being cold to the touch. In severe cases, the frozen skin may start to separate, and the affected parts may even be lost.

In mature bulls, frostbite can affect the scrotum. This can cause testicular degeneration and permanent infertility. In some cases, bulls with frostbite can overcome the injury and be able to breed in 60–90 days. In other cases, they can become infertile.

Visual and breeding soundness examination

The success of the breeding season hinges on whether your bulls can perform their job to the best of their abilities. A breeding soundness exam can tell you whether you are setting yourself up for failure or for success this breeding season.

The examination starts with a visual inspection of the bull to make sure they are healthy and alert, in ideal body condition and sound on all four feet. The veterinarian should look for common signs of frostbite, including accumulated manure and/or bedding on the bottom of the scrotum. This visual inspection is followed by a more physical inspection of the prostate, scrotum, testes, vesicular glands and penis; for instance, the veterinarian should check whether the penis can fully extend. An ejaculate will also be collected at this time to assess sperm motility and morphology.

Body condition and nutrition

Now is also a good time to start looking at bull body condition overall, and this means focusing on your nutritional and mineral programs. It is easier and cheaper to put on condition over a longer length of time than to have the “Oh no!” moment.

The ideal body condition for bulls is a 6 at turnout time. Bull age, breed, size, weather and time until turnout will determine the appropriate feeding program. Bulls that are too thin or too fat at turnout are usually less active and likely will not travel as far to cover the number of cows they need to. Typically, on a mature bull, a body condition score is equal to 120 pounds. If they wintered hard and are in a body condition score of 3–4, those bulls should be gaining 2 pounds or so per day now to be in the ideal condition by turnout.

Talk to your nutritionist or use one of the numerous online tools provided through various state extension programs to help you put a feeding program together. Sampling your feedstuffs will also give you more precise nutrient and ingredient information to use in these programs. Given the diverse weather last year, there was plenty of variation in feed quality.

Trace mineral supplementation

The key to a good nutrition program is making sure your bulls get enough mineral supplementation — and in the right form.

Copper, zinc, selenium and manganese, as provided through Alltech’s Bioplex® and Sel-Plex® organic trace mineral technologies, play crucial roles in bull fertility. Zinc is important for bull libido, testosterone synthesis and testicular size. Copper is important for libido and sperm production and volume. Selenium helps with sperm viability, and manganese is involved in hormone production.

 

Winter weather could have caused new and unforeseen challenges for many producers. Given the economics for cow-calf producers, it is imperative to get the herd set up to be as productive as possible this breeding season. We all know how hard it is to work with and manage bulls; however, if there was ever a breeding season to ensure your bulls are at the top of their game, it is this one.

Have you looked at your bulls lately?

Sow mortality: The hidden consequences

Submitted by tile on Wed, 04/02/2025 - 06:39

My first experience in pig farming was in Brazil. That is my bias. I needed to come to the U.S. to experience the impact of PRRS on a swine farm. I was horrified with how much damage a nasty strain can cause.

I have also observed many big-picture similarities between the U.S. and Brazilian pig industries, though. These include genetics, vaccines, antibiotics, disinfectants, corn-SBM diets, prolapses, how we value the breeding target, and many other performance metrics.

However, the difference between the countries in one key metric is quite shocking. This is sow mortality.

I am not fighting in Brazil’s corner, but using the 2024 data, the U.S. industry had 16% sow mortality, twice the Brazilian percentage. Can we attribute this solely to PRRS? A decent part, but we still see a ton of sows that die from “unknown/other” reasons. I am sure many of those deaths could be prevented.

A hard-to-control consequence of high sow mortality on-farm is the impact on herd parity structure, frequently showing up as a greater percentage of sows in both extremes of the sows’ parity graph. Besides the notorious negative impact on the herd and on growing pig immunity, the whole farm throughput is reduced. A recent analysis that compared three different parity structures, including over 623 herds, highlighted that farms that maximize the percentage of P3 to P5 sows are more productive. Figure 1 shows the three patterns of parity herd structure, sows within P3 and P5, and piglets weaned per sow per year.

Figure 1. Parity distribution of 3 different patterns and their respective percentage of sows within P3 and P5. Each dot represents a sow farm, and the blue line is the quadratic function of the parity structure pattern. Adapted from Sanz-Fernández et al., 2024.

 

Now let’s compare sow farms with high and low sow mortality in real-world numbers.

Imagine two 2,000-sow farms with an annual replacement rate of 45% (Figure 2). If Farm A has a 20% sow mortality rate, that means 400 sows per year die there. To keep the farm inventory, with the 900 gilts that enter every year, another 500 sows are culled. In a more favorable scenario, Farm B has an annual death loss of 10%, or 200 sows. That means that 700 other sows leave the farm as cull animals.

A diagram of a product being measured

AI-generated content may be incorrect.

Figure 2. Comparison between two 2,000-sow farms with different sow mortality and cull sows per year.

 

In the grand scheme of things, that does not tell the whole story of the 10% difference in sow mortality effect. I like to look at the other side: the cull sows. Here is the “juice.”

That 200-sow-per-year difference on Farm A accounted for mortality, and Farm B for cull sows represents an extraordinary opportunity to improve the breeding herd quality. How? Well, on Farm B, voluntary culls — those that you actively select to be culled due to age, poor performance, or behavior issues — will walk into a truck and even bring revenue. On Farm A, those 200 are dead sows. Some are in gestation, some in lactation, but regardless, they will not walk into a truck or produce any further revenue. To make matters worse, most of the time, those 200 are not the least productive. In the above example, we can say that Farm B gets 10% better than Farm A every year.

If you tell a new hire that approximately 1/5 of the sows die or are euthanized every year, plus 1/5 of the born-alive piglets will not be weaned, how mentally prepared does this person need to be? So here is another hidden consequence: the emotional impact on the employees, who care about the herd but must spend many days per year euthanizing sows and/or moving dead sows to the compost area.

Walking into a farm and saying, “Our sow mortality is sky-high at 17%; we need to reduce that immediately,” might not resonate with the team. Instead, make it tangible. Does everyone know what 10% mortality means in the weekly losses of sows? On a 1,100-sow farm, that’s the difference between losing two sows per week or exceeding that threshold. Set a clear, achievable goal: If the team keeps weekly mortality at two or fewer sows per week, they earn their bonus for maintaining sow mortality under 10%. When expectations are clear and the plan executable, results follow. Identifying the $100 and the $1 jobs is the first step; executing the $100 ones is the second and, most of the time, the last.

Make this part of the farm’s culture, and you will save many preventable death losses and avoid suffering from the hidden and costly consequences of high sow mortality.

Sustainable dairy farming and quality feed: Crespi Invernizzi's success

Submitted by tile on Tue, 04/01/2025 - 04:36

Massimo Crespi runs Crespi Invernizzi Farm in Sedriano, close to Milan, where they raise high-quality dairy cows. With around 190 cows, the farm is known for producing excellent milk and is part of the San Angiolina cooperative, famous for Grana Padano cheese.

The farm’s story began in 1982, when Massimo’s father and uncles started the business. In 2015, Massimo, his brother Alessandro and his cousin Samuele took over, continuing the family’s legacy of sustainable dairy farming.

A commitment to high-quality feed production

At Crespi Invernizzi, the focus is not only to raise healthy cows but also to produce high-quality dairy cattle feed — all while upholding high standards in sustainability.

The farm grows a variety of crops, including alfalfa, permanent grasslands, sorghum, autumn-winter crops, and corn. These are carefully selected to meet the nutritional needs of the cattle. The sorghum and autumn-winter crops provide the fibre needed for the animals’ diet, while corn is used for its high starch content, which is vital for supporting strong energy levels and overall health in cows.

Forage management: Adapting to climate challenges

Extreme weather patterns in recent years have posed significant challenges for forage production and animal welfare at Crespi Invernizzi, with increased water stress and unpredictable conditions threatening crop yields and feed quality.

To combat these issues, the farm has introduced resilient crops such as sorghum, which can endure harsh climatic conditions and provide a stable food source for cattle. Additionally, the farm has optimised forage management by incorporating Egalis® inoculants from Alltech, which significantly improve nutrient protection and reduce dry matter loss.

Massimo highlights the positive impact of utilising Egalis solutions, with notable enhancements in silage mass, particularly in terms of acidification and stability. The solution ensures consistent feed availability but also supports the overall health of Crespi Invernizzi’s livestock. The improved nutritional value and long-term stability of the silage contribute to better performance and well-being for the animals, even after extended storage periods.

These strategies collectively help mitigate the effects of climate change and improve carbon footprint, securing both sustainable farming practices and optimal livestock nutrition.

The practical benefits of Alltech’s Egalis line

One of the standout features of the Egalis line which significantly benefits the dairy industry is its ease of use. The products dissolve effortlessly in solution and do not cause any operational issues, even when applied during fieldwork. At Crespi Invernizzi, this practicality has made it easier for the team to integrate the inoculants into their harvesting routines.

Moreover, Egalis does not require refrigeration, which makes it even more convenient for storage. The silage inoculant can be kept in a dry, normal-temperature environment, saving the farm both space and energy costs.

Continuous monitoring of feed quality and forage management

At Crespi Invernizzi, maintaining the highest-quality feed is a top priority. The farm works closely with a dedicated animal nutritionist who regularly monitors the quality of the feed and silage. The nutritionist ensures that both the stored feed and mixed feed are up to standard, helping the farm maintain optimal milk production. In particular, the farm focuses on managing the dry matter content and the NDF (neutral detergent fibre) levels of the crops, which play a crucial role in the nutritional profile of the feed.

The link between high-quality feed and superior milk production

The team at Crespi Invernizzi knows that the key to producing high-quality milk lies in the quality of the feed. This is especially important for Crespi Invernizzi as it supplies milk to a dairy factory that produces Grana Padano cheese. The direct correlation between high-quality silage and superior milk production has been evident on the farm, and Massimo emphasises that the farm’s success is due to a continual focus on the nutritional value of the feed.

Technical support from Alltech: A valuable partnership

In addition to the benefits of the Egalis line, Crespi Invernizzi values the ongoing technical support provided by Alltech. The Alltech team assists the farm at each step of the process, from evaluating crops before harvest to inspecting the silage during the fermentation process. This collaboration has been crucial for optimising feed quality and ensuring long-term success.

Self-sufficiency through sustainable practices

One of the farm's core goals is to be as self-sufficient as possible when it comes to producing feed for the cows. By growing its own crops, Crespi Invernizzi not only ensures high feed quality but also reduces costs associated with purchasing external feed. This focus on self-production aligns with the farm’s commitment to sustainability and long-term profitability.

Conclusion: A model for sustainable dairy farming

Crespi Invernizzi Farm’s success is a result of careful planning, innovative practices, and a commitment to producing high-quality feed. By embracing sustainable farming techniques, such as the introduction of resilient crops like sorghum and the use of Alltech’s Egalis line for silage management, this farm has been able to overcome the challenges posed by adverse weather and maintain the health and productivity of its cattle.

As Crespi Invernizzi continues to evolve, its focus on quality and sustainable forage management will undoubtedly ensure its continued success in the dairy farming industry.

Biosecurity tips for poultry farming to prevent bird flu

Submitted by tile on Mon, 03/31/2025 - 06:35

With confirmed cases of avian influenza on the rise in the UK and Ireland, biosecurity in poultry farming is at the forefront of everyone’s minds. 

Whilst most biosecurity protocols are standard across poultry units it is always best to be mindful of farm-specific requirements, including good cleaning and disinfection practices if bringing equipment onto different sites, to try and provide best protection for poultry farmers and their flocks.

If in doubt, check with the farm manager prior to arrival and do not attend sites unless necessary.

There is not yet a mandatory housing order in the UK as there is in Ireland, and whilst keeping free-range birds indoors provides another level of protection for birds, it does increase pressure on litter management where birds would usually spend the majority of their days out on the ranges.

Signs and symptoms of avian influenza in poultry

Avian influenza (AI), a disease caused by type A influenza viruses, can infect both wild and domestic birds. Several factors can contribute to the spread of AI, such as migratory bird flight patterns, international trade, and points of cross-contact between humans and wild birds. AI is more commonly detected in colder regions due to the resilience of the virus in low-to-freezing temperatures.

There are two clinical types of influenza virus in poultry: highly pathogenic (HP) and low-pathogenic (LP). The HP strains of bird flu can spread rapidly among poultry flocks and may cause multi-organ failure and sudden high mortality levels. The LP strains of bird flu form as asymptomatic infections, respiratory disease, and/or drops in production.

Symptoms indicating avian flu in birds include:

  • Sudden death without any warning signs
  • Purple discoloration of the wattles, comb and legs
  • Swollen head, eyelids, comb, wattles and hocks
  • Soft-shelled or misshapen eggs
  • Decreased egg production
  • Lack of energy, appetite and coordination
  • Diarrhoea
  • Nasal discharge
  • Coughing or sneezing
  • Ruffled feathers

How to help prevent avian influenza in poultry

Avian influenza viruses spread through direct contact with infected birds or through contaminated feed, water, equipment and clothing. Therefore, biosecurity is the first and most important method of prevention at the farm level. Poultry producers are advised to:

Prevent wildlife access: Reduce attractants such as standing water, feed spills, and improperly stored waste. Install deterrents such as exclusionary netting and screens, repellent gel, bird spikes, and scare devices, which should be moved and replaced frequently.

Control access of people and equipment: If infected wild birds are in the area, reduce the movement of people, vehicles or equipment to and from areas where poultry are kept. Change your clothes before and after contact with your flock, and ensure that any visitors do the same.

Maintain high sanitation levels: Clean and disinfect regularly, from the property and poultry houses to equipment, vehicles and even footwear. For commercial poultry owners, clean and disinfect your poultry housing at the end of each production cycle. Wash your hands thoroughly before and after contact with birds.

Maintain surveillance and reporting: At a minimum, follow local regulations regarding breeder flock monitoring and testing protocols. Contact a vet if you have any concerns. Also, be sure to report illnesses and bird deaths. Quick action will help protect other flocks in the area if the disease is confirmed.

 

Effective poultry management is crucial in reducing the risk of avian influenza and protecting flocks from potential outbreaks. By implementing strong biosecurity measures, maintaining proper sanitation, and monitoring bird health closely, poultry farmers can help safeguard their operations. Staying vigilant and proactive is key to ensuring the health and productivity of poultry flocks in the face of evolving disease challenges.

Chelated minerals for better sow reproduction

Submitted by tile on Fri, 03/28/2025 - 06:26

Optimising nutrition is crucial for ensuring high reproductive performance and longevity in sows, as well as overall health and productivity. Among the essential components within the sows’ diet, trace minerals play a vital role in maintaining the health and reproductive efficiency of our breeding herd.

Alltech’s chelated minerals offer a superior solution to trace mineral nutrition by enhancing bioavailability, absorption and utilisation in the sow.

The importance of trace minerals in sow reproductive performance

Although they are only required in modest amounts, trace minerals such as zinc, copper, iron, manganese and selenium are fundamental to sow nutrition, particularly in supporting fertility, farrowing house performance, and longevity within the herd (Figure 1). However, it’s not just mineral concentrations within the diet that require consideration — the actual source of these minerals is significantly important.

Traditionally, commercial sow diets have been formulated with inorganic sources of trace minerals, such as copper sulphate and sodium selenite, due to their relatively inexpensive cost. However, minerals from inorganic sources are extremely reactive in the premix, in the feed, and in the gastrointestinal tract of the animal, due to their poor stability. As a result, the uptake and utilisation of these minerals can be limited, resulting in suboptimal performance. Inclusion levels are also regularly over-formulated to ensure that the sows’ requirements are actually met, but this leads to high levels of mineral excretion and waste.

For this reason, there is increasing interest in alternative forms of trace minerals which are better absorbed, stored and utilised by the sow. Chelated trace minerals provide this effective alternative.

Modern animal production requires a modern approach to mineral supplementation

Alltech has proven that modern nutritional management can be achieved by supplementing chelated trace minerals in the form of Bioplex® minerals (including zinc, copper, iron and manganese) and Sel-Plex® organic selenium, which are scientifically and commercially proven to optimise sow nutrition. Because Bioplex and Sel-Plex are more stable and have enhanced bioavailability compared to inorganic mineral sources, pig producers can supplement their sows’ diets at significantly lower inclusion levels while still improving sow performance.  

Alltech’s approach to mineral management promotes several key benefits, some of which include:

  1. Improved sow performance: Bioplex and Sel-Plex have been shown to optimise reproductive performance, with more piglets born alive per litter. These mineral technologies also support milk quality, including higher mineral levels in the milk.
  2. Increased sow longevity: Bioplex and Sel-Plex contribute to the protection of cells from oxidative stress and inflammation. This protection is conducive to overall health and longevity as well as productivity.
  3. Enhanced mineral bioavailability and stability: Bioplex and Sel-Plex are designed with improved stability and bioavailability, ensuring that the minerals remain in a form that the sow can effectively absorb, store and utilize.
  4. Reduced mineral excretion: Through enhanced absorption and utilisation and lower inclusion rates, Bioplex and Sel-Plex help in reducing mineral excretion, thereby helping to reduce the environmental impact of intensive pig production.

 

A proven mineral solution for pig producers

European pig producers face increasing pressure to improve production efficiency while adhering to stricter environmental regulations. By incorporating Alltech’s trace mineral solutions into their nutritional programs, pig producers can unlock the full reproductive potential of their sows while supporting overall health and longevity, improved efficiency, and more profitable production.

Key takeaways from the Alltech 2025 Asia Import Risk Analysis

Submitted by tile on Wed, 03/26/2025 - 01:15

Mycotoxin contamination in imported grains continues to be a critical challenge for animal feed producers in Asia. As feed production in the region grows, so does its reliance on imported raw materials from major grain-exporting regions such as Europe, North America and Latin America.

The Alltech 2025 Asia Import Risk Analysis sheds light on mycotoxin risks, offering valuable insights for both ruminant and monogastric nutrition.

Understanding mycotoxin risks in imported grains

Dr. Ghazanfar Naseer, Alltech Asia regional technical manager for ruminants and mycotoxins, emphasizes that mycotoxin contamination poses a serious threat to animal health and productivity.

“Mycotoxins are invisible, but their impact is not,” he warns. “For ruminants like dairy and beef cattle, these toxins can lead to lower milk production, reduced growth rates and long-term health issues.”

Similarly, Gustavo Sa Ribeiro, Alltech Asia regional technical manager for monogastric, highlights how mycotoxins can significantly affect swine and poultry production.

“As we learn more about mycotoxins, we see the damaging effects on animal performance and feed efficiency. Understanding their presence in imported raw materials is essential for making informed decisions.”

Regional mycotoxin profiles: Key findings

Europe

  • Mycotoxin risk varies significantly between Northern and Southern Europe.
  • Northern Europe: Deoxynivalenol (DON) is the primary concern, impacting dairy cows with reduced milk yield and higher somatic cell counts.
  • Southern Europe: Aflatoxin contamination is prevalent in corn, posing liver health risks and reducing productivity.

United States

  • Pre-harvest rains led to Fusarium-related mycotoxin challenges, with DON, zearalenone, and fumonisins being the most prominent.
  • 85% of U.S. corn samples tested were contaminated with fumonisins, which can cause feed refusal and immune suppression in cattle.
  • Post-harvest drought resulted in damaged kernels and foreign matter, increasing storage and transportation risks.

Canada

  • Fusarium toxins were dominant in wheat and barley samples.
  • Although the risk was lower than in the previous harvest, individual samples contained elevated mycotoxin levels, stressing the need for routine testing.

Brazil

  • Aflatoxin, DON, fumonisins and zearalenone continue to be the primary concerns.
  • 75% of Brazilian corn samples tested positive for fumonisins, with some reaching 22,800 ppb, a dangerously high level for ruminants.
  • High Fusarium toxin concentrations pose severe risks, particularly for swine.

Implications for ruminant and monogastric species

Ruminant:

  • Corn byproducts from North America and Europe have an average risk equivalent quantity (REQ) of 392 for dairy cows, indicating a high risk level.
  • This could result in a 5% drop in milk production and a 7% increase in somatic cell counts, impacting milk quality and profitability.
  • Fumonisins in Brazilian and U.S. corn can impair feed efficiency and overall herd health.

Building better silage: The foundations for success

Submitted by tile on Wed, 02/26/2025 - 21:58

Silage production is a cornerstone of modern farming, ensuring high-quality feed for livestock. Yet achieving consistently good silage requires a strong foundation built on best management practices, informed decision-making, and the right tools.

Here are some insights on how farmers can optimize the silage process — from field to feed passage — by implementing practical, science-backed strategies.

Laying the foundation for quality silage

Success in silage-making begins long before harvest. It starts with understanding the specific needs of the farm, including factors like machinery, storage space and feed-out rates. A tailored approach helps farmers maximize forage quality while addressing potential constraints. The key steps in establishing a solid foundation for silage production include:

  • Climate considerations: Selecting forage species that can withstand temperature or moisture stress
  • Field preparation: Minimizing soil contamination during harvest to maintain forage purity
  • Fertilization strategies: Applying appropriate nutrients for optimal forage growth and quality
  • Harvest timing: Identifying the optimal growth stage for harvesting
  • Ensiling best practices: Managing the harvesting and storage process effectively to preserve nutrients

Managing nutrients from field to feed

While the challenges of maintaining nutrient integrity during ensiling have remained relatively consistent over the past 15 years, advances in technology and management practices have significantly improved silage outcomes. The key principles of effective silage-making include:

  • Harvesting at the correct stage of maturity in a hygienic manner
  • Chopping forage to an appropriate length to minimize air pockets
  • Using a suitable silage treatment based on forage type and feeding system
  • Rapid ensiling and compaction to achieve high density
  • Sealing silage properly and maintaining airtight conditions throughout storage
  • Minimizing disruption to the silage face during feed-out

Controlling air and microbiology for optimal fermentation

Oxygen is the enemy of good silage. When air is present, undesirable microorganisms thrive, leading to nutrient losses and heating. Historically, farmers relied on chemical salts or heterofermentative bacteria to control these issues, but this often resulted in dry matter losses and reduced nutritional value.

Today’s homolactic silage inoculates are an excellent alternative to their heterofermentative counterparts, offering advantages in fermentation and nutrient recovery. In addition, advancements in silage-making techniques and equipment have revolutionized the process, offering better control and improved outcomes:

  • Modern mergers and rakes reduce soil contamination during collection.
  • Precision chopping minimizes air spaces in ensiled forage.
  • Improved compaction techniques enhance silage density and stability.
  • Enhanced defacers and block cutters preserve the integrity of the silage face during feed-out.
  • True oxygen barrier plastics dramatically reduce air infiltration, extending silage stability by up to four days.

Maximizing silage potential with informed choices

With technological advancements in management, silage inoculants and plastics, farmers have more effective options for silage success — but combining them can be tricky, especially the combination of the right plastic with the right inoculant. Understanding the advantages and disadvantages here is essential to making informed decisions, ensuring that the resulting silage meets both quality and stability expectations.

At Alltech, we are committed to helping farmers navigate these choices with expert advice, on-farm support, and research-backed solutions. A good choice is an informed choice, and with the right foundation, silage success is within reach. For example, using Egalis® Ferment, a high-specification homolactic inoculant, alongside Egalis® True OB, a high-tensile silage plastic with industry-leading oxygen barrier properties, can deliver significant benefits.

Silage success powered by science

Producing high-quality silage requires more than just following tradition — it demands a science-driven approach and modern management techniques. By combining best practices with cutting-edge solutions like Egalis Ferment and Egalis True OB, farmers can reduce dry matter losses, protect nutrients, and enhance feed stability.

Safeguard feed quality with mycotoxin analysis

Submitted by tile on Thu, 02/20/2025 - 23:06

Mycotoxin contamination can severely impact grain storage, dry matter and total mixed ration (TMR) quality, posing significant risks to livestock and humans consuming impacted products. To mitigate these risks, effective mycotoxin analysis and testing strategies are essential, ensuring safe, high-quality feed and efficient, profitable production.

Understanding mycotoxins in grain storage

Grain silos play a crucial role in protecting harvested grains, but improper storage can encourage mold growth, leading to harmful mycotoxins. High concentrations of aflatoxin B1, deoxynivalenol (DON) and fumonisins are particularly concerning in stored grains such as corn, wheat and barley. These toxins, especially in high concentrations, can compromise milk production in dairy cows and reduce the quality of TMR diets.

Regular mycotoxin detection using advanced testing methods like LC-MS/MS (liquid chromatography-tandem mass spectrometry) provides precise insights into contamination levels, ensuring grain safety.

Best practices for reducing mycotoxin risks in storage

  1. Cleaning and fumigation: Clean silos before storage to eliminate fungal spores.
  2. Moisture control: Keep moisture below 14% to prevent mold proliferation.
  3. Temperature regulation: Maintain cool, stable temperatures in storage facilities
  4. Aeration and ventilation: Ensure proper airflow in grain silos to reduce humidity.
  5. Regular mycotoxin testing: Use high-quality test kits and routine analysis to detect contamination early.

Insights from the Alltech 2024 Harvest Analysis across the regions

The 2024 growing season brought unique challenges and opportunities across key agricultural regions, with fluctuating weather patterns and varying crop conditions.

Europe

The latest Alltech European Harvest Analysis revealed key mycotoxin risks affecting grain and forage storage across Europe:

United States

The United States saw regional weather variability, with significant weather changes affecting crop health and mycotoxin levels in 2024:

  • All samples contained two or more mycotoxins, up from 97% last year.
