  • Patent number: 5606934
    Abstract: A pig feeder wherein the pigs feed from opposite side of a firmly fixed feed tray. The feed tray is fed with feed from an overhead hopper firmly fixed by means of a frame having two legs only which lie in diametrically opposite positions relative to the tray, and from the hopper there is a feed passage through which the feed passes to an outlet over the tray. In the feed passage is positioned a dispensing mechanism which is operated by a bar member which is moved by the feeding pigs. The feed falls from the outlet into the tray and the arrangement is that there is sufficient unobstructed clearance under the outlet to enable the pigs, which are aggressive animals, to compete vigorously with each other for the feed which falls on to the tray as the pigs can reach across the tray under the outlet.
