Abstract: The SNPs of CLPG gene in 113 Jiaxian Red cattle were detected by PCR-SSCP, and three genotypes (AA, AB and AC) were identified. The sequencing results showed that genotype AA was the wild type with C and T at the position 150 and 419, respectively, genotype AB and AC have mutations T419C, C150T, respectively. The polymorphism information contents (PIC) was 0.226, which indicated that the polymorphism of this population was relatively low. The associations of different genotypes with some of the growth and development traits were analyzed. The results showed that the individuals with genotype AA and AC had a larger body weight, body length than the individuals with genotype AB (P<0.05 or P<0.01, respectively), the individuals with genotype AA were better than those with AB in the circumference of cannon bone (P<0.05), the individuals with the genotype AB was significantly different with those of AA (P<0.05) and AC (P<0.01) in the hucklebone width, respectively.
