Abstract: A battery powered portable automatic animal feeding system for dispensing relatively finely divided dry feed material particularly suitable for domesticated animals such as cattle, hogs, or sheep; or for undomesticated animals such as deer. At predetermined feeding times and of predetermined quantities during each feeding time a single auger conveyor rotates and substantially uniformly and simultaneously along its entire length discharges feed material through a series of feed exit ports evenly spaced longitudinally along the bottom of an elongated tapered feed storage container and onto an existing flat feeding surface or feed bunk of variable height allowing animals access to the feed material on both sides of the feeding surface.
