摘　　要：本试验旨在研究饲粮中添加番茄红素对绵羊生长发育、屠宰性能和血清抗氧化指标的影响。选取体重为(22.0±0.5)kg的3月龄湖羊公羔30只,随机分为3组,每组10只,单栏饲养。对照组每天饲喂基础饲粮,试验组每天分别在基础饲粮中添加200和400 mg番茄红素。试验期共110 d,其中预试期10 d,正试期100 d。结果显示:与对照组相比,1)饲粮添加200和400mg/d番茄红素有提高绵羊平均日增重的趋势(0.05≤P<0.10),并可显著降低料重比(P<0.05);2)饲粮添加200和400 mg/d番茄红素可显著提高绵羊胸宽(P<0.05),添加200 mg/d番茄红素有提高体长、体高和胸围的趋势(0.05≤P<0.10);3)饲粮添加200和400 mg/d番茄红素有提高宰前活重、背肌重、肾脏重和GR值的趋势(0.05≤P<0.10),添加400 mg/d番茄红素可显著提高皮重(P<0.05),其他屠宰性能指标各组间无显著差异(P>0.05);4)饲粮添加200和400 mg/d番茄红素有提高血清超氧化物歧化酶活性的趋势(0.05≤P<0.10),添加200mg/d番茄红素可显著提高血清过氧化氢酶和谷胱甘肽过氧化物酶活性(P<0.05)。结果表明,饲粮添加番茄红素对绵羊生长发育、屠宰性能和血清抗氧化能力有一定的提高作用,本试验条件下以200 mg/d添加量的效果较优。This experiment was conducted to study the effects of lycopene supplementation on growth development,slaughter performance and serum antioxidant indices of sheep.Thirty male 3-month-old lambs of Hu sheep with the similar initial body weight of（22.0±0.5）kg were randomly divided into three groups with ten lambs in each group,and they were housed individually in pens.Lambs in control group were fed a basal diet,while lambs in other two trial groups were fed the basal diet added with 200 and 400 mg/d lycopene,respectively.The experiment lasted for 110 days with 10 days for adaptation and 100 days for sampling.The results showed as follows：1）compared with control group,diet supplemented with 200 and 400 mg/d lycopene could tend to increase average daily gain（0.05≤P〈0.10）,and significantly decrease feed/gain of sheep（P〈0.05）.2）Compared with control group,diet supplemented with 200 and 400 mg/d lycopene could significantly increased chest width（P〈0.05）,and supplemented with 200 and 400 mg/d lycopene could tend to increase body length,height at withers and chest circumfrence（0.05≤P〈0.10）.3）Compared with control group,diet supplemented with 200 and 400 mg/d lycopene had tendency to increase pre-slaughter live weight,Longissimus dorsi muscle weight,kidney weight and GR value（0.05≤P〈0.10）,and supplemented with400 mg/d lycopene significantly increased leather weight（P〈0.05）,but there were no significant differences in other slaughter performance indicators among three groups（P〈0.05）.4）Compared with control group,diet supplemented with 200 and 400 mg/d lycopene tended to increase superoxide dismutase activity in serum（0.05≤P〈0.10）,and supplemented with 200 mg/d lycopene significantly increased the activities of serum catalase and glutathione peroxidase（P〈0.05）.It is concluded that dietary supplemented with lycopene can improve growth development,slaughter performance and serum antioxidant indices of sheep to some extent,and the optimal dose is 200 mg
