摘　　要： 本文对近年来母猪胎盘效率与产仔数关系的研究进行了综述 ,母猪的胎盘效率与其繁殖性有正相关关系 ,特别是与总产仔数和产活仔数 ,达极显著相关 ;不同品种猪的胎盘效率因猪体型、品种而有差异 ;胎盘效率遗传力为 0 .4 6 ,基于胎盘效率的选择是提高猪的窝产仔数的有效方法之一。 The recent advances in placental efficiency of swine were reviewed in this article. The results showed that there was positive relationship between placental efficiency and reproductive traits, especially litter size. The placental efficiency of different breeds has significantly different. The heritability estimates for placental efficiency was 0.46. Placental efficiency can be used as a trait to select for the reproductive performance of sows.
