Oat

The Oat is a species of cereal grain, and the seeds of this plant. They are used for food for people and as fodder for animals, especially poultry and horses. Oat straw is used as animal bedding and sometimes as animal feed.
Oats are often served as a porridge made from crushed or rolled oats, oatmeal, and are also baked into cookies together with wheat flour. As oat flour or oatmeal, they are also used in a variety of other baked goods and cold cereals, and as an ingredient in muesli and granola. Oats may also be consumed raw, and cookies with raw oats are quickly becoming popular. Oats are also occasionally used in Britain for brewing beer. Oatmeal stout is one variety brewed using a percentage of oats for the wort.
Oats also have non-food uses. Oat straw is also used in corn dolly making, and it is the favourite filling for home made lace pillows. Oat extract can be used to soothe the skin conditions, e.g. in baths, skin products, etc.
A now obsolete Middle English name for the plant was haver , surviving in the name of the livestock feeding bag haversack. In contrast with the names of the other grains, "oat" is usually used in the plural.
