猪IGFBP2基因多态性及其与胴体、肉质性状的关联分析
Polymorphism oflGFBP2 Gene and Its Association with Carcass and Meat Quality Traits in Pigs
摘要
Abstract
This study was conducted to investigate the potential association of variation in the insulin-like growth factor binding protein 2 (IGFBP2) gene with carcass and meat quality traits in pigs.IGFBP2 is a member of IGFBP family,maps to chromosome 15.PCR-Msp I-RFLP method was used to detect the SNP g.171C＞T (GenBank Accession No.BV727778) at the second intron in Large White × Mei Shan F2 population (n=382).This SNP was significantly associated with back fat thickness,loin eye height,eye muscle width,bone percentage,and other traits (P＜0.01),and was significantly associated with eye muscle area,fat percentage and the ratios of fat to lean,flower fat,color value (LD) and color value (BF) (P＜0.05).These results suggested that IGFBP2 as a potential candidate gene affects on carcass and meat traits.关键词
