我们研究了为动物生产系统（即生长猪）配制日粮对环境的影响。动物生产的经典方法是使用基于最低成本饮食配方的生长模型。这种最佳饮食通常是通过线性规划建立的。这种方法可能会导致氮和磷排泄形式的不利环境影响。提出多标准（两个和三个标准）模型的目的是解决经济和环境因素。我们将模型应用到两个现实生活环境：魁北克（加拿大）和法国，并进行一些比较。我们表明，在这两种情况下，都可以以相对较低的成本实现氮和磷排泄的显着减少。
We look at the environmental impact of formulating diets for an animal production system, namely the case of growing pigs. The classic approach in animal production is to use a growth model based on the least-cost diet formulation. This optimal diet is generally established by linear programming. Such an approach can lead to adverse environmental effects in the form of nitrogen and phosphorus excretions. Multi-criteria (two and three criteria) models are proposed with the aim of addressing both economic and environmental considerations. We apply the models to two real-life contexts: Québec (Canada) and France, and make some comparisons. We show that important reductions in nitrogen and phosphorus excretions can be achieved at relatively low costs in both contexts.
