非洲猪瘟背景下猪育种策略探讨

Perspectives on pig breeding in the context of African swine fever

非洲猪瘟给我国养猪业造成巨大损失,也沉重地打击了我国的猪育种工作,虽然目前非洲猪瘟已大大缓解,各核心育种场也逐渐恢复了育种工作,但非洲猪瘟并未消除,未来的育种工作将面临非洲猪瘟常态的挑战。在这样的背景下,我国的猪育种工作应做出针对性的改变,主要体现在:(1)建立严格的永久性的生物安全体系;(2)调整育种目标;(3)自动化、智能化、物联网技术的应用;(4)加快基因组选择技术应用;(5)建设高质量、高度生物安全的种公猪站;(6)利用冷冻精液技术。

African swine fever(ASF)has caused huge losses to the swine industry in China,and inparticular to the pig breeding.Currently.the epidemic situation of African swine fever(ASF)has been greatly relieved,and the key breeding farms have gradually restored their breeding work.However,African swine fever(ASF)has not been eliminated and it may exist for a long time,which means it is very normal that our breeding work will face the challenge of African swine fever(ASF).Accordingly,our breeding work needs to be changed,which include 1)setting up strict and permanent biosecurity system;2)adjusting breeding goals;3)using automation,intelligence and Internet of Things technologies;4)speeding up the use of genomic selection;5)building high quality boar stations with high biosecurity level;6)utilizing frozen semen.
