Abstract: The laboratory beagle dogs were fed with formula feeds containing different protein sources (vegetable protein, animal protein and mixed protein).There were no significant differenes in food intake in groups. Protein sources had no obvious effect on weight gain. There was equal protein digestibility in mixed protein group and vegetable protein group. The lowest protein digestibility was in animal protein group. The organic digestibility in mixed protein group was higher than that of the other two groups.The lowost digostibility of calcium and phosphorous was in the vegetable protein group. Therefore in order to control the feed cost and under the situation without the high quality animal protein, feeding dogs with mixed protein is better.

摘要： 用不同蛋白质饲料 (植物蛋白质饲料、动物蛋白质饲料和动植物混合蛋白质饲料 )的配合饲料饲喂实验比格犬。各组的采食积极性和采食量没有明显差异 ;蛋白质来源对生长犬增重没有明显的影响。动植物混合蛋白饲料组与植物蛋白饲料组蛋白质消化率相近 ,动物蛋白饲料组最低 ;动植物混合蛋白饲料组有机质消化率高于植物蛋白饲料组和动物蛋白饲料组 (P <0 0 5 ) ;钙磷消化率以植物蛋白饲料组最低。因此为控制饲料成本并在不能获得高品质动物性蛋白的情况下 ,用动植物混合蛋白饲料饲喂实验犬效果较好
