摘 要：
以陶赛特做父本的三个杂交组合,杂一代初生重A组(陶×寒藏F1)为4.1kg,B组(陶×寒)为3.8kg,C组(陶×藏)为4.3kg,比对照组(藏羊)提高0.9kg、0.6kg和1.1kg;断奶重以C组为最高,比对照组提高15.7kg,A组和B组分别比对照组提高11.9kg和7.5kg;6月龄活重也以C组最高,比对照组提高19.4kg,A组比对照组提高15.7kg,B组比对照组提高10.5kg;A、B和C组12月龄羊胴体重比对照组提高109%,89%,59%;日增重提高幅度以C组为99.6g,A藏组为93.3g,B组为92.6g,几项指标与对照组差异均极显著(P<0.01)。

摘 要：
The birth weight of F_1 of three-way cross with Dorset sheep as paternity in A (Dorset×F_1 of small-tail Han sheep ×Tibetan sheep),B(Dorset ×small-tail Han sheep)and C(Dorset ×Tibetan sheep)groups were 4.1,3.8 and 4.3 kg,and increased 0.9,0.6 and 1.1 kg than that in control group (Tibetan sheep),resp;The weaning weight of F_1 in C group was highest whick was 15.7kg more than that in control group,and one in A and B groups increased 11.9 and 7.5 kg than that in control group resp;the live weight of F_1 at the age of six month in C group was also highest,which was 19.4 kg more than that in control group.and one in A and B groups increased 15.7 and 10.5 kg than that in control group resp;the carcass weight of F_1 at the age of twelve month in A,B and C groups increased 109%?89% and 59% than that in control group resp;the daily gain of F_1 in C,A and B groups increased 99.6,93.3 and 92.6g resp.There was a very siginificant difference (P<0.01) between several indexes of A,B and C groups and control group.
