Yeast-based feed additives contain live or dead yeast cells and also products of their fermentation. They modulate alimentary tract microbiome composition and also immune functions. Supplementation can stimulate the gastrointestinal tract development. Yeast-based products are effectively used in the prevention of diarrhea in calves.
