ABSTRACT:
This is concerned with a hog feeder which has a center feed supply with a feeding trough around it with vanes which move the feed out from a plateau in the center under the feed supply and a ledge which prevents the feed from falling into the trough by gravity or vibration thus requiring a hog to move the vanes to get feed.
