摘　　要：选择体重、年龄相近、健康的中卫山羊妊娠母羊50只,随机分为5组,组间体重差异不显著(P>0.05)。Ⅰ、Ⅱ、Ⅲ组试验羊饲喂相同能量水平、不同蛋白质水平的日粮,Ⅱ、Ⅳ、Ⅴ组试验羊饲喂相同蛋白质水平、不同能量水平的日粮。试验结果表明,在本试验条件下,蛋白质水平在9.91%、日粮能量水平在10.15MJ·kg-1时,最适合中卫山羊妊娠母羊的生长,且饲料报酬最高。Fifty pregnant ewes（healthy and simiar of weight and age） were chosen to be randomly divided into five groups.There was no significantly in weight of every group（P0.05）.The groupⅠ,Ⅱ and Ⅲ fed with the same energy and different protein levels dietary;the group Ⅱ,Ⅳ and Ⅴ fed with the same protein and different energy levels dietary.The results showed that the dietary protein level of 9.91% and energy level of 10.15 MJ·kg-1 were the most suitable for the growth of zhongwei goat pregnant ewes,and the feed conversion was the highest in the experimental condition.
