Pleurotus eryngi - Feed Ingredient

Pleurotus eryngii, commonly known as the king oyster mushroom, is an edible fungus that is cultivated for its firm texture and nutritional profile. It is rich in dietary fiber, protein, vitamins, and minerals and contains bioactive compounds such as beta-glucans. The mushroom is typically processed by drying and milling into a powder, which helps preserve its natural components and facilitates its inclusion in various formulations.

In equine nutrition, Pleurotus eryngii is used as a supplement to provide fermentable fiber and naturally occurring polysaccharides. The beta-glucans present in the mushroom are of interest due to their potential to support normal digestive functions. While direct research in horses is limited, preliminary investigations in other species support its use as a complementary ingredient.
