目的研究日粮添加大豆油对绵羊羊毛脂含量及品质的影响.方法将20只体重相近（40～45kg）的1.5岁左右敖汉细毛母羊按单因素随机设计原理分成4组,每组5只,全部单栏饲养,分别饲喂添加了0%、2%、4%、6%大豆油的日粮,试验期8个月.结果添加4%大豆油显著提高了羊毛脂的含量（P〈0.05）,2%和6%的添加水平不影响羊毛的含脂率（P〉0.05）.羊毛自然长度、羊毛细度、净毛率不受大豆油添加水平的影响（P〉0.05）,4%、6%大豆油的添加降低了污毛的产量（P〈0.05）.结论考虑生产性能,为改善羊毛的含脂率,添加4%以下的大豆油比较合适.

Objective To study the effects of supplying soybean-oil in sheep diet on fat content of wool and wool quality.Methods 20 pieces of Aohan Merino sheep,with an initial live weight of 40～45 kg,were randomly allotted to feed one of four concentrate diets containing 0%,2%,4%,or 6% soybean-oil for eight months.Results The fat content of wool at 4% soybean oil addition level significantly increased compared with the control（P0.05）.2% soybean oil and 6% soybean oil added to diets had no significant effect on fat content（P0.05）.There was no difference in the natural length of wool,wool fineness and wool skrinkage among the treatments（P0.05）.Wool yield at 4% and 6% addition level decreased compared with the control group（P0.05）.Conclusion Considering performance,supplying under 4% soybean oil is reasonable for improving fat content of wool.
