STAT5A gene plays a significant role in growth traits by affecting JAK/STAT pathway. We identified two SNPs which were
related to growth traits from 206 healthy and adult purebred individuals of Guizhou Black goats using the methods of direct
sequencing and PCR-SSCP. The association analysis between genotypes and growth traits showed that the individuals of
genotype TC were superior than CC in chest girth significantly (P<0.05), and the individuals of GA were significant superior
than GG and AA in chest girth and body weight (P<0.05). Besides that, the heterozygotes had higher growth traits than those
of homozygotes in general. Therefore, we made a conclusion that the two SNPs of STAT5A gene will serve as markerassisted
selection for improving growth traits in goats, but we should still continue to prove the validity of the conclusion by
enlarging the total samples and breeds.
