    Abstract: An animal feeding device for delivering feed to animals and particularly for delivering feed to pigs and the like. The feeder includes an open lid hopper having a swingable front partition, operable by an animal, the upper section of which is downwardly disposed from the horizontal by at least the angle of repose of the feed. The lower section of the partition, with no external forces applied thereto, is maintained in parallel spaced relationship with respect to a vertical rear wall. The hopper communicates with a feed trough having a rear portion upwardly disposed from its substantially horizontal base portion by at least the angle of repose of the feed. The rear portion of the trough also serves as a deflecting device for feed passing from the hopper into the trough. Also included are a plurality of low profile divider bars having a loose fit extension into the hopper for agitating the feed.
