Yeast Culture - Feed Ingredient

Yeast culture refers to the dried and fermented product resulting from the growth of live yeast cells, most commonly Saccharomyces cerevisiae, on a nutrient-rich substrate. Unlike live yeast or yeast extract, yeast culture includes both the residual yeast cells (viable or non-viable) and the media on which the yeast was grown. It is not considered a probiotic, but rather a fermentation product with functional feed properties.

In equine feed formulations, yeast culture is used as a digestive aid and nutritional supplement. It contains fermentation metabolites, B-vitamins, peptides, amino acids, and cell wall components such as β-glucans and mannan-oligosaccharides. These components are thought to support microbial activity in the hindgut and improve fiber digestion and nutrient utilization.

The following equine feeds, supplements and products contain Yeast Culture as an ingredient.
