陆川猪和大白猪胰岛素样生长因子2基因对生长性状的效应分析

Abstract

Abstract: To reveal the SNPs of insulin-like growth factor-2 (IGF2) gene and evaluate its relationship with growth traits, we used PCR-SSCP to identify one SNP of IGF2 gene, and analyzed the effects of the SNP on birth weight(BW), weaning weight(WW), average daily gain(ADG) in Luchuan and Large White pigs. The results showed that IGF2 gene had significant effects on BW, WW, ADG in Large White pigs(P<0.05), and had significant effects on BW, ADG in Luchuan pigs (P<0.05). It could be inferred that IGF2 gene might be one of candidate genes affecting the growth traits in Luchuan pig. The polymorphic site could be used to marker assisted selection program for growth traits in Luchuan pig.

Key words: insulin-like growth factor-2 gene; Luchuan pig; Large White pig; growth trait
