摘要 非洲猪瘟背景下,猪场面临两大难题,一是安全问题,二是种源问题。通过不断提升生物安全等级能够有效保障猪场安全,但种源问题却一时难以解决。在这种特殊背景下,部分猪场开始大胆创新的将三元母猪作为种源进行生产。但是,国内外关于三元母猪种用的资料文献几乎没有,无法形成有效的借鉴。一时之间,关于三元母猪究竟有没有种用价值和如何提高其种用价值成为养猪业的热门话题。文章从三元母猪种用价值、种用劣势和改善措施三个方面进行深入剖析和探讨,旨在为猪场了解和使用三元母猪提供参考。 Under the background of African swine fever,pig farms will encounter two major issues,namely security and shortage ofbreeding pigs.It has formed a consensus that persistent improvement on biosafety could protect pig farms against contagion.However,the shortage ofbreeding pigs will remain ffor a long time.Currently,some farms start trying to breed the commercial DLY sows as gilts to restore pig farm production.There are few literatures about the reproductive performance of the commercial DLY sows,and it is widely discussed that whether the commercial DLY sows are capable of breeding and how to improve the reproductive performance.In order to help the pig farms to evaluate the reproductive performance of the commercial DLY sows and to improve it,this paper will conduct indepth analysis and discussion from three aspects:the breeding value,breeding disadvantages and improvement measures of the commercial DLY sows.
