Baileys Better Biome. Baileys Better Biome brings together three valuable digestive enhancers in the form of a prebiotic, a probiotic yeast and postbiotics which work synergistically as a unique support package for the horse's microbiome to help promote optimum gut health.Prebiotic , Baileys Digest Plus, a short chain Fructo-Oligosaccharide (sc-FOS) acts as a food source for beneficial gut bacteria helping them to flourish at the expense of pathogenic species.Probiotic yeast, Saccharomyces cerevisiae stimulates fibre-digesting bacteria, helps increase their numbers and also helps reduce the risk of excess acidity in the hindgut.Postbiotics - These are defined as inanimate microorganisms and/or the end products of microbial fermentation, like metabolites, that confer a health benefit on the host. The natural microbial population of the horse�s gut are continually producing these metabolites, which include volatile fatty acids from fibre, B vitamins and other compounds, which are beneficial to health
