猪产仔性状与雌激素受体基因PvuⅡ多态性效应的Meta分析
Meta-analysis of the Effect of the Estrogen Receptor Gene Pvu Ⅱ Polymorphism on Pig Litter Traits
摘要
Abstract
The aim of this study was to perform the Meta-analysis of the effect of the estrogen receptor gene Pvu II polymorphism on pig litter traits. The 33 papers identified from CNKI, WANFANG Data, VIP and PubMed (including 9 429 sows) were analyzed, and a Meta-analysis was performed to assess and combine the data. Under a random-effects model, litter sizes were significantly lower in the AA genotype group compared with those in the genotype AB and BB groups. Heterogeneity within and between studies was observed. In conclusion, the Meta-analysis demonstrated that the allele B and genotype BB were beneficial for pig litter traits. Heterogeneity between studies was mainly due to the effect of pig breeds and many other factors.关键词
