Oat Hulls - Feed Ingredient
Oat hulls are the outer protective layers of oat grains (Avena sativa), removed during the milling process. They consist primarily of lignocellulose and serve as a structural component of the oat kernel. Due to their high fiber and low digestibility, oat hulls are considered a byproduct with limited nutritional value for most livestock species.
In equine nutrition, oat hulls are primarily used as a source of indigestible fiber or as a filler ingredient in pelleted feeds. While they provide bulk and aid in pellet formation, they contribute little to digestible energy or essential nutrients. However, their low starch and sugar content make them a suitable carrier ingredient in low-calorie feed formulations and supplements. Excessive inclusion of oat hulls in a horse’s diet may dilute overall nutrient density without offering significant digestible fiber benefits.
The following equine feeds, supplements and products contain Oat Hulls as an ingredient.
