The device of the present invention provides a novel feeder which generally comprises a feed reservoir, a trough, and an actuable feed dispensing mechanism all of which are operably connected to provide a structure which readily accommodates the three-dimensional space-envelope described by the normal range of feeding movements of the feeding animal thereby preventing injury to the animal and minimizing eating movements that are wasteful of feed. The device of the invention optionally incorporates a novel, feed-dispensing mechanism which is removably situated in the throat of the feed reservoir. The mechanism comprises a series of removable adjacent tubular segments, exemplified by cylindrical ring segments, through which runs a removable ring segments, through which runs a removable rigid support member, such as a rod. In the un-actuated state, the feed dispensing mechanism completely occludes the throat of the feeder. The upward displacement of the segments by the animal's snout/nose creates an opening in the throat of the feed reservoir through which feed can then pass. When the segments return to their original position by the force of gravity, the throat is once again occluded and feed flow stops.
