ARTICLE 86 FEED & ADDITIVE MAGAZINE September 2024 “Delivering high-quality and consistent feed that is optimized for each customer's specific needs helps ensure the optimal effect of live yeast additives. These additives are important for various aspects of animal health and performance, including growth rates, feed efficiency, immune function, reproductive performance and the quality of meat or milk” In the rapidly evolving and intricate world of animal nutrition, the quality and efficacy of feed are crucial for maintaining livestock health and productivity. Live yeasts probiotics, increasingly valued for their benefits in animal health and performance, may face significant challenges during feed processing due to harsh conditions such as high temperatures, mechanical stress, pressure, formulation and oxygen exposure. These factors can compromise the viability of probiotics, as well as degrade essential nutrients. For probiotics to deliver their full benefits, yeasts must remain live until they reach the livestock’s digestive tract; otherwise, their effectiveness can be compromised. This underscores the need for feed technology to better safeguard and maintain feed quality. A QUEST FOR LIVE YEAST PROBIOTIC VIABILITY To address these challenges, Lallemand Animal Nutrition has developed a portfolio of live yeast products tailored to the specific needs of modern feed production. Here is a focus on LEVUCELL SC, the specific live yeast dedicated to ruminant feed. The LEVUCELL SC vermicelli is designed for standard formulation processes, composition or pelleting processes. Depending on the size and density of the feed ingredients, this form can be used to optimize mixability and ensure homogeneous distribution of the probiotic to reduce the risk of segregation in the final feed. Uniform dispersion is key to delivering a consistent dose of viable yeast to each animal. For applications involving high levels of reactive ingredients such as copper, magnesium and zinc, Lallemand also offers LEVUCELL SC MICROBEAD* technology. These spherical particles are engineered to seamlessly integrate with mineral premixtures and supplements, providing enhanced protection against chemical degradation without compromising mixability. An alternative solution in Lallemand's arsenal is LEVUCELL SC TITAN, a patented microencapsulation technology that offers reliable protection under challenging processing conditions like pelleting.
