摘　　要：为研究大蒜秸秆饲喂对小尾寒羊增重及羊肉品质的影响,按照大蒜秸秆添加比例不同,把30只小尾寒羊随机分为试验组1、试验组2和对照组,每组10只,测定了不同饲料营养成分,不同组别小尾寒羊采食量、日增重、肠道疾病发生及羊肉品质等相关指标。与玉米饲料、玉米秸秆对比,大蒜新鲜秸秆的钙和粗纤维含量较高,蒜素含量为17.80 mg/100 g。不同大蒜秸秆饲料添加比例对肉羊增重影响显著,随着添加比例增加对肉羊增重具有显著的促进作用,试验组1和试验组2比对照组日增重增加35.29%和17.65%,大蒜秸秆作为粗饲料能够显著提高羊肉中不饱和脂肪酸和饱和脂肪酸的含量,粗料中添加大蒜秸秆比例较高(本试验70%)的条件下,羊肉中不饱和脂肪酸顺-9-油酸、亚油酸含量比对照增加370.58%和60.70%,限制性氨基酸、必需氨基酸和肉味氨基酸显著提高,分别比对照增加4.98%、3.82%和1.51%。肉羊养殖中,粗饲料中大蒜秸秆对比常规青贮玉米作为主要成分饲喂,对于小尾寒羊肉羊增重和羊肉品质都有显著的促进作用。To study the effect of garlic straw feeding on weight gain and mutton quality of Small Tailed Han sheep, 30 Small Tailed Han sheep were randomly divided, according to different proportions of garlic straw in roughage, into experimental group 1, experimental group 2 and control group, ten sheep in each group. The related indexes such as different feed nutrients, feed intake, daily gain, the occurrence of intestinal diseases and mutton quality of Small Tail Han sheep in different groups were determined. Compared with corn feed and corn straw, the content of calcium and crude fiber in fresh garlic straw is relatively high, and the content of allicin is 17.80 mg/100 g. The results indicate that garlic straw feed proportion has significant influence on weight gain of mutton sheep,with the increase of adding proportion, the weight gain of mutton sheep is significantly promoted. The daily weight gain of test group 1 and 2 is 35.29% and 17.65% higher than that of control group. Garlic straw feeding could significantly improve the content of unsaturated fatty acids and saturated fatty acids in mutton. Under the condition of high garlic straw proportion of crude materials(70% in this experiment), the content of unsaturated fatty acids cis-9-oleic acid and linoleic acid in mutton is increased by 370.58% and 60.70% respectively compared with the control. The restricted amino acids,essential amino acids and meat flavor amino acids in mutton are increased by 4.98%, 3.82% and 1.51%respectively compared with the control. The results show that garlic straw as the main ingredient of roughage could significantly promote the weight gain and quality of mutton compared with conventional silage corn as the main ingredient feeding.
