摘要: 梅山猪是太湖猪的一个类群,以繁殖力高闻名于世。本文通过对梅山猪高产仔数性状的生理结构、遗传因素等加以综述,主要阐述了梅山猪的子宫、胎盘对高产的作用、影响多产仔性能QTL的精细定位、主效基因的多态性与高产仔数之间的关系及早期胚胎特有的发育机能对高产的影响。探讨了如何从基因组水平研究梅山猪高产的成因,以期为深入地解析梅山猪高产的分子遗传机制提供一些参考。

Abstract: Meishan pig, one of the Chinese Taihu pig breeds, is well known all over the world for the high prolificacy. The recent research progress in the physiological structure and hereditary factors affecting the high litter size of Meishan pig was summarized in the article. The role of the uterus and placenta on the high litter size, and QTL fine mapping affecting the high farrowing performance, the association of polymorphisms of the major genes with high litter size, and the effect of early embryonic development function on high prolificacy were described. Furthermore, how to investigate the causes of high litter size at the genome level was discussed, so as to understand the molecular genetic mechanism of high prolificacy in Meishan pig.
