摘　　要：为探究杜湖杂交对湖羊产羔数和羔羊初生重的影响,试验采用杜泊公羊与湖羊公羊分别对经产湖羊母羊进行配种,记录每组母羊的产羔数、羔羊性别和初生重等信息,并进行均值检验和单因素ANOVA分析。结果发现,杜湖杂交组(DH组)与湖羊本交(HH组)母羊产羔率分别为207.30%、215.46%;DH组和HH组组内不同产羔类型下相同性别羔羊初生重相互之间均存在极显著差异(P<0.01);DH组和HH组产单羔、双羔、三羔和四羔羔羊平均初生重分别为4.37 kg和3.18 kg、3.90 kg和2.98 kg、3.48 kg和2.89 kg、3.01 kg和2.72 kg,其相同产羔类型的公羔及母羔初生重之间存在极显著差异(P<0.01);说明杜湖杂交后母羊产羔率影响不显著,但对湖羊羔羊初生重有显著影响。To explore the effect of Dorper×Hu hybridization on Hu sheep's litter size and birth weight,Dorper rams and Hu rams were used to breed multiparous Hu sheep ewes,respectively.The litter size,sex,and birth weight of ewes in each group were recorded,and the mean test and one-way ANOVA analysis were carried out.The results showed that the lambing rates of ewes in DH group and HH group were 207.30%and 215.46%,respectively.There were significant differences in the birth weight of lambs of the same sex under different lambing types in the DH group and HH group(P<0.01).The average birth weight of single lamb,double lamb,three lambs,and four lambs in DH group and HH group were 4.37 kg and 3.18 kg,3.90 kg and 2.98 kg,3.48 kg and 2.89 kg,3.01 kg and 2.72 kg,respectively.There was a significant difference in birth weight between male lambs and female lambs of the same lambing type(P<0.01).It shows that the effect of ewe lambing rate after Du-Hu hybridization is not significant,but it has a significant effect on the birth weight of Hu lamb.
