不同杂交组合对产羔数和羔羊早期生长性能的影响
Effect of Different Cross on Lambing Rate of Ewes and Early Growth Performance of Lamb
摘要
Abstract
In this study,Hu sheep were dam,white Suffolk,white Dorper and Dorset were male parents,the cross combination were Suffolk(♂)×Hu sheep(♀),Dorper sheep(♂)×Hu sheep(♀),Dorset sheep(♂)×Hu sheep(♀)respectively. The lambing rate and early growth performance of crossed offspring were measured and analyzed,the pure breed Hu sheep was control,by the way, under the same feeding and management. The results showed that the lambing rates of HH and TH were 257% and 223% respectively,more 16 peccentage points than SH,more 13 percentage points than DH. The survival rates of HH and TH were 74.03% and 85.29% respectively,the TH was more 7 lambs than SH and more 10 lambs than DH. The birth weight of the cross was more than that of the control,and the body weight of male lamb was more than that of female lamb. In the respect of average daily gain, THF1was 30.89% more than HH(P<0.01),SHF1 and DHF1 were respectively more 20.05% and 19.99% than HH(P<0.05).The female lamb of THF1was more 25.90% than HH on the average daily gain(P<0.01).Therefore,the experiments provided the mode for breeding multiple and economic sheep that would adapt the natural condition of Xinjiang.关键词
