A multicommodity, multiregional linear programming model is employed to obtain price differentials between 16 U.S. regions for corn, barley, grain sorghum, and oats. The price differentials are used to obtain loan support rates (for the 1974 crop) in each region, for each grain, so that relative...

Livestock rations are formulated to minimize feed cost subject to nutritional requirements for a target performance level, which ignores the potentially substantial cost of disposing of nutrients fed in excess of nutritional requirements. We incorporate nutrient disposal costs into a modified...
