摘　　要：选用藏羊与小尾寒羊杂交后代的羯羊21只,分成试验A、试验B和对照组,每组7只,在基础日粮和饲养方式完全相同的情况下,试验组日粮中分别添加甘肃榆中县生产的复合添加剂预混料和青海丁香集团生产的复合添加剂预混料,对照组只喂基础日粮,经50d试验。结果表明:试验A组、B组平均增重7kg和7.9kg;平均日增重为0.140kg和0.158kg。而对照组的平均增重和日增重分别为5.8kg和0.117 kg;试验A组与对照组比增重差异不显著(P>0.05),试验B组差异显著(P<0.05),两试验组间差异不显著(P>0.05);料重比试验A组为6.29∶1,B组为5.25∶1而对照组为7.48∶1;两个试验组分别比对照组多盈利9.44元/只和16.64元/只,青海丁香集团生产的复合添加剂预混料饲喂效果优于甘肃榆中县生产的复合添加剂预混料。21 wether which were crossing offsprings of Tibetan sheep with small-tail Han-sheep were divided into test A,test B and control groups and seven sheep per group. The basis ration and the feeding way was completely identical among sheep in two test groups and control group. The ration of the sheep in the test groups was added the compound premix produced in Yuzhong county of Gansu province and by Qinghai Lilac Corp, respectively. The ration of the sheep in the control group was the basis ration. The test period was 50days. The results showed that the average grain of sheep in the test A and B groups were 7 and 7.9kg, and the average daily gain were 0. 140 and 0. 158kg, respectively, and the average gain and daily gain of sheep in the control group were 5.8 and 0. 117kg, respectively. There was not significant difference in the gain between the sheep in the test A group and the control Group （ P 〉 0.05 ） and between the sheep in the test A and B groups （ P 〉 0.05 ）. There was significat difference in the gain between the sheep in the test B group and the control group （ P 〈 0.05 ）. The ratio of feed 6.29： 1,5.25：1 and 7.48： 1, respectively. The profit of two to body weight in the test A,test B and control groups were test groups increased 9.44 and 16.64yuan per sheep than that in the control group, respectively, indicating that the feeding effect of the compound prmix produced by Qinghai Liac Corp. was better than that produced in Yuzhong county of Gansu province.
