摘　　要：日粮中添加0、30、60 g/(只.d)脂肪酸钙分别在普通羊舍和暖棚羊舍中育肥小尾寒羊56 d,结果表明:添加60 g/(只.d)脂肪酸钙可以显著提高绵羊日增重(P<0.05),但并不提高经济效益;在普通羊舍中,添加30 g和60 g脂肪酸钙可分别提高绵羊日增重13.3%(P>0.05)和33.2%(P<0.05),而在暖棚中,添加脂肪酸钙后并未影响绵羊日增重;羊舍类型对绵羊日增重、采食量无显著影响,添加脂肪酸钙也不影响绵羊总采食量.Fatty acid calcium salts of 30 and 60g/（sheep · day） was supplemented in the dietary and Small Tail Han sheep was feed for 56 days in ordinary pen and greenhouse pen respectively. The results showed that 60 g/（sheep · day） fatty acid calcium salts （FAC） could improve the average daily gain（ADG） significantly,but it could not enhance economic efficiency. For ordinary pen, supplementing FAC for 30 g and 60 g（sheep · day） increased ADG by 13.3 % （P〉0.05） and 33.2 %（P〈0.05） respectively compared with control group, but ADG were not different in greenhouse pen. Both ADG and feed intake were not effected by the pen types,and FAC also did not affect the total feed intake of sheep.
