摘要
自从2018年非洲猪瘟在中国暴发以来,为了尽快恢复产能,我国很多猪场在生产上开始采用洋三元商品母猪留作种用。通过收集某大型猪场的二元(LY)母猪和洋三元(DLY)商品母猪的生产记录,统计两者在生产成绩上的差异,并综合其他文献来分析洋三元商品母猪留作种用的优缺点,给出改进的措施,为后非洲猪瘟时期养猪生产提供参考。
Since the outbreak of African swine fever(ASF)in China in 2018,many farms have begun to use threebreed crossbred(DLY)sows for breeding in order to restore sow’s productivity.In this paper we collect the breeding records of two-breed crossbred(LY)and three-breed crossbred(DLY)sows on large-scale pig farm,and analyze the diff erences in reproductive performance between the two kinds of sows.we also review other literature to provided some advise to improve those production performances in the post-African swine fever era.
