Ingredient

Yeast

Yeast, typically represented by species such as Saccharomyces cerevisiae, is a microbial ingredient valued in equine nutrition for its high-quality protein content and diverse nutrient profile. It provides essential amino acids, B-complex vitamins, and trace minerals, all of which contribute to maintaining overall metabolic health in horses.

Cultivated through controlled fermentation processes on nutrient-rich substrates, yeast is subsequently harvested and dried, resulting in a stable ingredient that can be easily incorporated into feed formulations. The cell wall components, notably beta-glucans and mannans, are recognized for their potential to support gut health and modulate the immune response. These functional properties make yeast a versatile component in equine diets, aimed at enhancing digestive efficiency and promoting overall well-being.

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