摘　　要：多配方平行设计是另一类畜禽饲粮配合方法,本研究旨在将这种方法应用于动物饲料配方。采用不同组合的多配方平行设计同时配合了生长猪7个不同阶段猪群的饲粮,比较与分析饲粮单位价格、原料用量和养分含量。通过这种设计方法产生的49个生长猪饲粮配方的能量、钙、磷、粗蛋白质、氨基酸、总氮和矿物质的养分含量,都达到或超过美国国家研究委员会(2012)提出的猪营养需要的推荐量,也满足最低成本的要求。实例表明,多配方平行设计能同时配合多个畜禽饲粮,并能在一个大的范围内选到更好的配方,应用于动物饲料配方设计具有实际可行性。A parallel design with multiple-formulas is another kind of method of formulating diets. This study was conducted to apply the parallel design with multiple-formula to animal feed formulation. The parallel design with different combinations of multiple-formulas was used for formulating 7 diets for different periods of grow-ing pigs,and the amounts of feed ingredients,nutrient consumption and cost of the diets were compared and analyzed. Energy,calcium,phosphorus,crude protein,amino acids,total nitrogen and minerals from all 49 diets for grow ing pigs using the parallel design met or exceeded the nutrient requirements of pigs recommended by NRC（ 2012）,and also the cost of the diets reached the minimum objective. The illustrations show that the parallel design with multiple-formulas is able to formulate multiple diets for livestock and poultry simultaneously and to select a better least-cost formula in a large range,and has the actual feasibility for the animal feed formulation.
