  • Patent number: 6959664
    Abstract: A swine feeder for use in feeding individually housed gestating swine. The feeder includes a hollow tube containing feed. The tube controls the amount of feed by having its lower, angled end contained within a feeding tube that is moveable by the individual sow to discharge the feed only when the sow applies a force to the feeding tube. The feeder may be connected to a supply of feed, and typically, the feeder is attached to the individual crate of each sow such that a limited amount of feed is dispersed into the sow's feeding area, usually a trough.
