【Abstract】 The results of crossbreeding experiment of Han-sheep with small-tail(HS) reared in Qinghai Province with Polled Dorset(PD) showed that F1 of HS×PD was such advantiges as fast-gain and good meat yield.The body weight of F1 of HS×PD at the age of three months and six months increased 1.29 kg(P<0.05) and 5.58 kg(P<0.01) than that of HS,respectively.The daily gain increased 29.82g,and the carcass weight,the meat percentage and the ege muscle area increased 5.13kg,4.58kg and 4.0 cm(P<0.01) than those of HS,respectively,suggesting that there was significant crossbreeding effect.更多还原
