The Oat (Avena sativa) is a species of cereal grain. White oats are preferred for milling and are used for food for people, and also as fodder for animals, especially poultry and horses. Oat straw is used as animal bedding and also sometimes used as animal feed. White oats, which account for most U.S. production, are grown north of the Ohio River and east of the Rocky Mountains.
White oats are standardized under the U.S. Standards for Oats.
