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. A wire grid extends from the butt plate upwardly into the hopper such that agitation or movement of the butt plate by animals feeding within the trough causes corresponding movement of the wire grid. To control the flow of food from the hopper into the trough, the butt plate is adjustable relative to the trough so as to vary the size of the opening through which the food must flow in order to become accessible to animals feeding in the trough. This adjustment is effected by a pivoted lever which is controlled from a handle located in the open top of the hopper.
