Digestive Health

A healthy digestive system is key to nutrient utilization. Otherwise, the quality and availability of feed has no value if nutrients cannot be digested and absorbed. Perdue Animal Nutrition recognizes the importance of a quality probiotic, and their role within the microbiome, for optimal animal production and health. We have invested in creating an extensive bank of proprietary and patented microorganisms, along with unique production systems.  This allows us to have flexibility in application methods and improved product stability. Our advances offer a range of probiotic species by selecting specific bacteria to provide specific solutions and delivering them in an easy-to-use product.
