摘　　要：基因多态性是影响猪生长性状的重要因素之一。随着分子生物学技术的迅速发展,选择优势的基因可促进猪育种体系,提高猪的生长性状。文章主要综述GH、IGF-1、IGF-2和MyoG基因的多态性对猪生长性状的影响,为确定猪生长性状的主效基因或候选基因提供参考,为选择有利的等位基因提供依据。Gene polymorphism is one of the important factor that affect the growth traits of pigs.With the rapid development of molecular biology technology,the selection of superior genes can promote the pig breeding system and improve the growth traits of pigs.The article mainly reviews the effects of GH,IGF-1,IGF-2 and MyoG gene polymorphisms on pig growth traits,providing a reference for determining the major genes or candidate genes of pig growth traits,and for selecting favorable alleles in accordance with.
