Oats are rolled or crushed into oatmeal, or ground into fine oat flour. Oatmeal is chiefly eaten as porridge, but may also be used in a variety of baked goods, such as oatcakes, oatmeal cookies and oat bread. Oats are also an ingredient in many cold cereals, in particular muesli and granola. Oats are also used for production of milk substitutes (e.g. oat milk).
Oats are also commonly used as livestock feed when extra carbohydrates and the subsequent boost in energy are required (e.g. horses and camels). The oat hull may be crushed ("rolled" or "crimped") to more easily digest the grain, or may be fed whole.
