【摘要】：为了研究胎次和分娩季节与PIC母猪繁殖性能的关系,选取杨凌本香农业产业集团有限公司三个PIC父母代种猪场的2014和2015年共1.2万头母猪的生产记录,统计不同胎次和分娩季节对母猪繁殖性能的影响。结果表明,第8胎母猪繁殖性能显著低于其它胎次(P0.05),可以从第8胎开始淘汰母猪。除木乃伊胎受季节影响显著外,其它繁殖性能不受季节影响。高温应激对木乃伊胎的形成影响显著,可以通过夏季降温等措施降低木乃伊胎的发生率。
[Abstract]:In order to study the relationship between birth order and parturition season and reproductive performance of PIC sows, 12,000 sows were recorded in three PIC parent breeding farms of Yang Ling Benxiang Agricultural Industry Group Co., Ltd in 2014 and 2015. The results showed that the reproductive performance of the eighth sow was significantly lower than that of the others (P0.05N), and the sows could be eliminated from the 8th embryo, except the mummy fetus, which was significantly affected by the season. Other reproductive performance was not affected by seasons. High temperature stress had a significant effect on the formation of mummies and could reduce the incidence of mummies by cooling down in summer.
