肉羊遗传育种与繁殖技术发展趋势

Development Trend of Genetic Breeding and Reproduction Technology of Meat Sheep

在羊养殖产业发展中,由于很多农牧民群众不注重羊品种性能的保护和品种改良,优质种公羊的利用率不合理,存在无序杂交和野交的现象,使肉羊品种生产性能逐渐下降,繁殖能力降低,生产周期变长,饲料利用率下降,不利于提高养殖效益。为加速肉羊品种改良进程,可利用遗传育种技术和现代繁殖技术,筛选出优质的基因型,进行有效的扩繁养殖,加速羊品种复壮,提高生产能力,最终提升经济效益。

In the development of sheep breeding industry,because many farmers and herdsmen do not pay attention to the protection of sheep breed performance and breed improvement,the utilization rate of high-quality breeding rams is not reasonable,there is often the phenomenon of disorderly hybridization and wild cross,the production performance of mutton sheep decreased gradually,the reproductive ability decreased,the production cycle prolonged,the feed utilization rate decreased,which was not conducive to raising the benefit.In order to speed up the improvement process of mutton sheep breeds,we can use genetic breeding technology and modern reproduction technology to screen out high-quality genotype,carry out effective propagation and breeding,accelerate the rejuvenation of sheep breeds,improve production capacity,and finally improve economic benefits.
