英文文献摘要：
The current method to derive livestock diets is to optimize cost performance subject to animal performance and resulting nutritional requirements via a linear programming model. In contrast, we examine the livestock diet formulation problem as a multi-criteria decision model with the criteria being cost performance, feed efficiency, and environmental compliance costs. We find that there are many situations where farm financial situations are improved by feeding products with higher costs per unit of protein but lower phosphorus levels.

目前获得牲畜饲料的方法是通过线性规划模型根据动物性能和由此产生的营养需求优化成本性能。与此相反，我们研究了牲畜饲料配方问题作为一个多标准的决策模型，标准是成本性能、饲料效率和环境合规成本。我们发现，在许多情况下，通过提高每单位蛋白质成本但降低磷水平的饲料，农场财务状况得到改善。
