Oat hulls are the outer protective coverings of oats, a type of cereal grain. They are typically removed during the processing of oats for human consumption, leaving behind the edible part known as the groat. Oat hulls are rich in fiber and are often used as a natural ingredient in animal feed, providing bulk and promoting digestive health. In addition to animal feed, oat hulls can be utilized in various industrial applications, such as in the production of biodegradable materials and as a component in some types of bedding. Their high fiber content makes them a valuable resource in promoting sustainability and reducing waste in agricultural practices.
