杜湖杂交对湖羊产羔数和羔羊初生重的影响
The Effects of Dorper×Hu Hybrid Crossbreeding on Litter Size and Birth Weight of Hu Sheep
摘要
Abstract
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.关键词
