Abstract: Jinghai Yellow chickens were chosen for experimental animal, PCR-SSCP was used to detect the SNP of zyxin gene in exon 9. The correlation between this SNP genotypes of zyxin gene and slaughter performances was analyzed. The result showed that one mutation was found in exon 9 which comprised three genotypes, named AA, AB and BB. Statistics analysis showed that AA genotype was significantly better than AB genotype on pectoral muscle weight (P<0.05), and AA genotype was significantly better than BB genotype on living weight as well as carcass weight in cocks (P<0.05). AA genotype was significantly better than BB genotype on living weight, cerebaria, claw weight and carcass weight (P<0.05), and AA genotype was significantly better than AB genotype on eviscerated chicken weight in hens (P<0.05).
