Due to the ever increasing resistance to antibiotics in animals, the use of microbial feed or water supplements, more commonly known as “probiotics”, are becoming more and more prevalent in the agriculture industry. Probiotics, which beneficially affect the host by improving its intestinal microbial balance, are to be used to help improve growth, production, and efficiency of the animal. Probiotics are not an alternative to the use of antibiotics for disease treatment but rather are an alternative to low-level, continuous use of antibiotics and when complemented with each other, they can create a very effective treatment program. Similarly, “prebiotics” are also feed or water supplements, however, their mode of action is meant to “stimulate” rather than “supplement” intestinal bacterial population. Prebiotics can be used very effectively in combination with probiotics resulting in a synbiotic. In either case, the use of pre and probiotics is rapidly growing as farmers are leaning more towards prevention rather than treatment. ProByn’s product line of high-quality prebiotics and probiotics have proven highly effective and add great value to any livestock feeding program around the world.
