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.

Abstract:

An animal-actuated feeding apparatus of the type that includes a feeding trough located beneath the discharge opening of a hopper containing the feed. The feed flows by gravity from the hopper through the discharge opening into the trough, but the feed flow is controlled by an animal-actuated dispensing mechanism. This mechanism includes a cradle-wiper assembly in which the cradle is rocked by the animal moving a paddle that extends into the trough area. Rocking of the cradle also agitates the feed stored in the hopper to prevent bridging across the hopper discharge opening. Manually adjustable means is also provided to control feed flow rate.
