Portable Self-Feeder for Supplementing Cattle on Range1

James G. Morris2,3, and Richard E. Delmas2

University of California, Davis, 95616

Abstract

A portable self-contained unit which permits supplementation of individual cattle or groups of cattle grazing common range is described. Each unit has four individual feed bunks with an electronic gate that controls entry of cattle to the supplements. When the electronic gates are in continuous operation, they rapidly discharge the lead-sulfuric acid storage batteries. Therefore, a circuit was devised which reduces this demand at all times except when cattle were feeding from the unit. The batteries are recharged by either solar panels or an alternator driven by a small gasoline motor.
