摘  要：
引进国外早熟、生长速度快、肉用性能好的肉用品种萨福克、无角陶赛特、杜泊羊与我国产羔率高、四季发情、适应性强的优良地方品种小尾寒羊杂交,获取杂交优势,进行羔羊肉的生产.试验结果表明:在相同的舍饲管理条件下,以同等营养水平饲喂杂一代羔羊和小尾寒羔羊,6月龄的平均日增重分别为:萨寒F1208.61 g、杜寒F1200.11 g、陶寒F1193.33 g、小尾寒羊144.11 g,各F1羔羊与小尾寒羊羔羊相比分别提高了44.76%,38.85%,34.15%.从出生到6月龄羔羊不同阶段(1月龄、4月龄、6月龄)的平均体重,萨寒F1>杜寒F1>陶寒F1>小尾寒羊.投入与产出比为:萨寒F11∶1.09>杜寒F11∶1.01>陶寒F11∶0.94>小尾寒羊1∶0.45.说明各杂一代羔羊的生长速度均快于小尾寒羊羔羊,平均体重大于小尾寒羊,投入与产出比高于小尾寒羊羔羊1倍以上,经济效益明显提高.

摘  要：
Some early maturity and rapid growth and good guality mutton sheep from foreign countries were introduced,such as Suffolk(S) and Poll Dorset(PD) and Dorper(D) cross with the small-tailed Hansheep(H),which was high lambing percentage and all the year round heat and strong adaptability to obtain the hybrid vigor and produce lamb.The results shows that under the same conditon in yard feeding and management and the same nutrition level,the average daily gains in 6 month ages lambs of Suffolk×Hansheep(SHF_1),Poul Dorset×Han sheep(PDHF_1),Dorper×Han sheep(DHF_1) and Han sheep×Han sheep(HH) were respectively 208.61g,200.11g,193.33g and 144.11g.Compared every F1 with HH,the average daily gain in six month ages lambs of every F1 inereased 44.76%,34.15% and 38.86% respectively.The different stages average weight from birth to six months was SHF_1>DHF_1>PDHF_1>HH.The rate of input and output value of SHF_1,DHF_1,PDHF_1 and HH was respectively 1∶1.09,1∶1.01, 1∶0.94and 1∶0.45.The growth rate of hybridized offspring was more rapid than pure lanbs of small tailed Ham sheep and average weight of every F_1 is higher than HH.The rate of input and output was more than two times and the economic benefit increased significantly.
