摘　　要：为测定不同杂交组合F1代羔羊屠宰性能,利用引进的国外优质肉用萨福克羊与本地绵羊进行杂交,对杂交羔羊屠宰性能进行测定。结果表明,萨土杂交一代羔羊的宰前活重(49.50 kg)、胴体重(23.20 kg)、屠宰率(59.04%)、肉骨比(3.89),眼肌面积(15.50 cm2)显著高于本地土种羊(P<0.05);萨细组合宰前活重(45.4 kg)、胴体重(22.8 kg)、屠宰率(57.09%)、肉骨比(3.03)、眼肌面积(13.50 cm2)显著高于本地细毛羊(P<0.05)。故利用萨福克羊杂交改良本地绵羊,在提高屠宰性能方面取得了较好的效果。The aim of the research was to mensurate the slaughter performance of F1 Lamb among different ized combination.This study analyzed the Slaughter Performance of hybrid Lamb by local sheep cross-breeding with Suffolk.The results showed that the pre-slaughter live weight（49.50 kg）,carcass weight（23.20 kg）,dressing percentage（18.14 kg）,ratio of meat with bone（3.89）,loin muscle area（15.50 cm2）of F1 hybrid between indegenous sheep and suffolk are significantly highter than that of indegenous sheep（P0.05）;the pre-slaughter live weight（49.50 kg）,carcass weight（23.20 kg）,dressing percentage（18.14 kg）,ratio of meat with bone（3.89）,loin muscle area（15.50 cm2）of F1 hybrid between fine wool sheep and suffolk are significantly highter than that of fine wool sheep（P0.05）.It is significant to improve the Slaughter Performance of local sheep by cross-breeding with Suffolk.
