摘　　要：为探究初产湖羊的繁殖性能,以新疆某养殖基地997只初产湖羊为研究对象,记录每只母羊的产羔数、羔羊性别和初生重等信息,并对羔羊的初生重进行了比较分析。结果显示,初产湖羊主要产羔类型为每胎产单羔、双羔和三羔3种,其中74.62%的母羊个体产双羔及以上。双羔公羊的初生重极显著高于母羔(P<0.01);三羔公羊的体重显著高于母羔(P<0.05)。随着母羊产羔数的增加,母羔体重呈极显著下降趋势(P<0.01);单羔公羊的初生重极显著高于双羔和三羔公羊(P<0.01),双羔公羊的初生重显著高于三羔公羊(P<0.05)。To explore the reproductive performance of primiparous Hu sheep,997 primiparous Hu sheep in a breeding farm were used as the research object in this study.The litter size,sex,and birth weight of each ewe were recorded,and the birth weight of lambs was compared.The results showed that the main lambing types of primiparous Hu sheep were single-lamb,double-lamb,and three-lambs per litter,and 74.62%of the ewes produced double lambs or more.The birth weight of male lambs in the double-lamb group was significantly higher than that of female lambs(P<0.01).The birth weight of male lambs in the three-lamb group was significantly higher than that of female lambs(P<0.05).The birth weight of female lambs decreased significantly with the increase in litter size(P<0.01).The birth weight of a single-lamb ram was significantly higher than that of a double-lamb and three-lamb ram(P<0.01),and the birth weight of a double-lamb ram was significantly higher than that of three lamb ram(P<0.05).
