Abstract: The 3′UTR polymorphism of IGF-ⅠR gene was detected by PCR-SSCP in 58 red steppes. The results showed that two allelomorphic gene, three genotype of IGF-ⅠR gene were detected. The associativity was analyzed between the polymorphism of slaughter and carcass traits. The results indicated that procured meat percentage and the ratio of meat in bone for AB genotype was higher than AA and BB genotypes(P<0.05), the rate of fat coverage for AA genotype was higher than BB genotype(P<0.05),and was no significant difference with AB genotype(P>0.05).

Key words: red steppes; insulin-like growth factor Ⅰ receptor(IGF-ⅠR); 3′UTR; single nucleotide polymorphism
