South Dakota State University
Current data on the livestock and grain industries of South Dakota indicate that the state is a net exporter of feeder cattle and feed grains, suggesting that if the feeder cattle and feed grains were retained within the state, the state’s beef feeding and packing industries could be expanded considerably. This study divided the state into seven regions based on their natural resource similarities to determine the optimum movement of feed grains and feeder cattle in South Dakota.
