ESR基因PvuⅡ位点对猪产仔数影响的研究进展
Research progress on the effect of the ESR gene Pvu Ⅱ on litter size in different pig breeds
摘要
Abstract
Litter size is a key trait that affects the economic efficiency of pig farming,its improvement and selective breeding has long been a major focus in the industry.With the continuous advancement of molecular biology technologies,particularly genome sequencing,molecular breeding techniques such as Best Linear Unbiased Prediction and Marker Assisted Selection have provided new approaches for pig breed enhancement and the development of high-yielding pig breeds.The screening and identification of major genes associated with litter size has become a research hotspot in pig genetic improvement.This article reviewd the effects of polymorphisms at the PvuⅡ site of the Estrogen Receptor gene on litter size across 44 pig breeds,including Large White,Landrace,Duroc,Erhualian,Jiangquhai,Jinhua,Taihu,Neijiang,Chenghua,Xiang,Zongdihua,Tibetan,Sujiang,Min,Sutai,Huai,Zhongsu,Baoshan and Saba pigs,aiming is to provide a reference for improving litter size across different pig breeds.关键词
