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.
