A pig feeder includes a hopper in which a supply of feed is stored, and a feed trough mounted adjacent a lower end of the hopper and in communication with the hopper through an opening therein so that feed in the hopper can pass into the feed trough. The trough includes a bottom wall, a front wall extending upwardly from the bottom wall and having a top edge, and a top face having a width extending between the top edge of the front wall and the hopper. The top face has at least one feeding hole therethrough which is substantially U-shaped having a curved portion and a straight portion, the curved portion of the feeding hole being remote from the hopper. The diameter of the curved portion is preferably equal to the height of the front wall so that pigs feeding from the trough must reach vertically downwardly to get to the feed.
