The current method to derive livestock diets is to minimize cost subject to animal performance and nutritional requirements that the performance level dictates. This method explicitly ignores the cost of over-feeding protein and minerals which must be disposed of with animal waste. Environmental compliance is a primary concern on livestock operations which must consider farm, and ?eld, levels of phosphorus and nitrogen. We reconsider livestock diet formulation to determine the cost effective diet using environmental compliance goals and resulting costs unique to the farm.
