摘　　要：随机选择75只中卫山羊哺乳羔羊,连同母羊分为5组,每组15只羔羊.各组分别饲喂不同蛋白水平的饲料,A组和B组饲喂粗蛋白的质量分数为17%的粉料和颗粒料,C组和D组饲喂粗蛋白的质量分数为19%的粉料和颗粒料,E组为对照组饲喂玉米粉料.试验结果显示:各试验组羔羊增体质量均大于对照组,其中B组羔羊增体质量最快,C组次之.经方差分析显示:B组和C组差异不显著,B组与D组差异显著,A组和E组差异极显著,B组不仅饲喂效果最好而且增体质量成本最低,也最经济.75 kids of Zhongwei Goats with their mothers were randomly divided into 5 groups, 15 kids in Each group. The kids were fed on the diets of different protein level. Group A and B were fed on the diets of powder forage and pellet forage containing 17% crude protein （CP）. Group C and D were fed on the diets of powder forage and pellet forage containing 19% crude protein （CP）. Group E was the control group fed on corn powder. The results showed that the weight gains of all experimental groups were better than that of control group. The kids in group B grew the fastest and the kids in group C followed. The difference between group B and group C was not significant （P〉0.05）. There was a significant difference between group B and group D （P〈0. 05）. There was a great significant difference between group A and E （P〈0.01）. The kids in group B grew the fastest with the lowest cost.
