ABSTRACT:
The present invention provides a novel feeder which readily accommodates the three-dimensional space-envelope described by the normal range of feeding movements of a feeding animal, minimizes eating movements that are wasteful of feed, and prevents injury to the feeding animal. The feeder optionally incorporates a novel, feed-dispensing mechanism which can be removed from the throat of the feeder reservoir. The mechanism has a series of removable adjacent tubular segments, such as cylindrical rings, through which runs a removable rigid support, such as a rod. When un-actuated, the mechanism completely occludes the throat of the feeder. When a feeding animal displaces the segments upwardly, feed passes through the opening created in the throat of the feeder. When the segments return to their original position by the force of gravity, the feeder throat is occluded and feed flow stops.
