Significance of life yeast culture as feed additives in horses Based on a literature review the article gives an overview on the roles of life yeasts in horse nutrition. In comparison to different studies on livestock, the knowledge of effects in horses is limited. The application of yeasts (e.g. brewers yeasts) is common practice to support the horse with nutrients. Yeasts can colonize the equine gastrointestinal tract and has an impact on the resident microbiota. Life yeast (Saccharomyces cerevisiae) is used as feed additive for instance after abdominal surgery or to prevent digestive disorders in sensitive animals. Some studies demonstrated a positive effect on the digestibility of acid detergent fibre. This could result from the stabilisation of the colonic milieu and an impact on the gut microbiota. Existing studies show that Saccharomyces cerevisiae cannot colonize the gastrointestinal tract of horses permanently. For the efficacy a continuous application of Saccharomyces cerevisiae seems important.
