Abstract: In this study, the single nucleotide polymorphisms of chicken EX-FABP gene were detected by PCR-SSCP method with different pairs of primers among 228 chickens from 8 populations. Results indicated that there were 5 mutation sites had been found: 645C T, 3254C T, 3266T C, 4272A G, 4282A G, the X2 test results showed that there was extremity significant difference(p<0.01) (Fragment 1) in the frequency of genotypes among breeds. Based on the detected polymorphisms, the effects of different genotypes on slaughter and meat quality traits were analyzed. The results indicated that there were significant differences between genotypes and Glu and Ash (p<0.05) (fragment 2) and significant differences between genotypes and Val (p<0.05) (fragment 8). It was concluded that the single nucleotide polymorphisms of chicken EX-FABP gene was not association with slaughter, but it was association between the polymorphisms and partial amino acid which can affect meat quality traits.
