摘　　要：【目的】旨在通过两种不同蛋白水平的全价颗粒饲料对舍饲湖羊公羔进行育肥分析研究,比较在相同管理条件下生产性能和屠宰性能的差异。【方法】选择4月龄体重相近、体况良好、健康的湖羊公羔200只,随机分为2组,即对照组和试验组,各组内公羔100只。在相同饲料管理条件下,对照组饲喂以棉粕为蛋白的全价颗粒饲料1,试验组饲喂以豆粕为蛋白的全价颗粒饲料2,进行为期60 d的育肥试验。【结果】试验结果表明,试验组的末重、总增重和平均日增重均显著高于对照组(P<0.05);在育肥30d时,试验组和对照组公羔平均日增重分别为342.34g和282.64g,试验组比对照组高出59.70g,两组差异极显著(P<0.001);在育肥60d时,试验组的屠宰率、胴体重、眼肌面积和GR值均高于对照组,但两组差异不显著(P>0.05);在经济效益方面,试验组的经济效益优于对照组,比对照组经济效益增加了23.87元/只。【结论】根据两种不同蛋白水平的全价颗粒饲料对湖羊公羔育肥生产性能和屠宰性能方面的影响对比可知,试验组饲喂的豆粕全价颗粒饲料2在湖羊公羔育肥方面效果显著,在今后的商品羊生产中值得推广应用。【Objective】The purpose of this study was to analyze the fattening effect of stall-feed male lambs of Hu sheep by two kinds of complete pellet feed with different protein levels,and to compare the performance of production and slaughter under the same management conditions.【Methods】200 Hu sheep male lambs with similar body weight,good physical condition,and no diseases at 4 months old were selected and randomly divided into two groups:a control group and an experimental group,with 100 lambs in each group.Under the same feed management conditions,the lambs in the control group were fed the complete pellet feed No.1 with cottonseed meal as main protein source,and those in the experimental group were fed the complete pellet feed No.2 with soybean meal as main protein source.A 60-day fattening experiment was conducted.【Results】The results showed as follows:the final weight,total weight gain and average daily gain of lambs in experimental group were significantly higher than those in control group(P<0.05).At 30 days of fattening,the average daily gains of lambs in experimental group and control group reached 342.34 g and 282.64 g,respectively,with an extremely significant difference of 59.7 g(P<0.001).At 60 days of fattening,the slaughter rate,carcass weight,eye muscle area and GR value of lambs in experimental group were higher than those in control group,and there were no significant difference between the two groups(P>0.05).The economic benefit of the experimental group was better than that of the control group,with an increase of RMB 23.87 per lamb.【Conclusion】According to the above comparison results,it could be speculated that the complete pellet feed No.2 with soybean meal protein in the experimental group had a significant effect on the fattening of Hu sheep lambs,and was worthy of promotion and application in the production of commercial mutton sheep in the future.
