Oat grasses are a type of cereal crop that is grown for both forage and grain production. They are often included in pasture mixes because of their high yield and palatability for livestock. Synonyms for oat grasses include Avena sativa, oat forage, oat hay, and oat straw. Oat forage is a common term used to describe the plant when it is grown specifically for livestock grazing. Oat hay and oat straw are utilized as livestock feed and bedding materials, respectively. Regardless of the name, oat grasses provide essential nutrients for livestock and can be an important component of sustainable agriculture practices.
