  • Patent number: 5718188
    Abstract: A computer controlled hog feed management system which utilizes two or more pre-ground and premixed rations which may be blended into feed and delivered to feed drops according to the animals' specific needs based on gender, weight, and average daily feed intake. Animal locations and feed requirements are entered into a computer which controls two or more ration transfer augers for the transfer of the previously prepared rations to a plurality of feeding stations, preferably after first passing through a blending hopper. The system utilizes auger transfer rates to determine proper feed blends and auger transfer rates and delivery distances to determine auger run times and feed drop on-off status for feed delivery to particular locations.
