Abstract: An animal feeder is disclosed which comprises a feed trough and a hopper mounted above the trough for automatically feeding stored food into the feed trough as it is consumed by animals feeding therein. Flow of food from the hopper into the feed trough is controlled by an agitator or butt plate located within the trough and spaced a predetermined distance from the bottom of the trough.
