Study on the Hybridization Effect of Bamei Mutton Sheep and Hu Sheep
The aim of this experiment is to crossbreed Bamei mutton sheep with Hu sheep,and use local Han lambs as controls to compare and analyze the reproductive performance,production performance,slaughter performance,and fattening benefits of Hu sheep ewes and Han crossbreeding ewes.This will provide data support for the utilization of Bamei mutton sheep and the crossbreeding mode of meat sheep in the Bayannur region.Research has shown that in the Bayannur region,the reproductive performance of Hu sheep is higher than that of local Han lambs;The 6-month old weight,slaughter rate,and fattening efficiency of Bahu hybrid lambs are higher than those of local Han hybrid lambs;The birth weight and weaning weight of single lambs are higher than those of double lambs and three lambs;The difference in slaughter rates between single lambs,double lambs,and three lambs is not significant.The results indicate that the Bayannur region can use the local meat sheep variety Bamei to crossbreed with Hu sheep and produce fattening commercial sheep Bahu hybrid lambs,which can increase the output of breeding ewes and improve fattening efficiency.
