Abstract. cIn this study, we reported the analysis of THRSP gene polymorphisms in 610 goats of three breeds: Xinong Saanen (SN), Guanzhong (GZ) and Boer (BG). We identified new allelic variant: P2-G39294A (GenBank acc. no. JN618075) in the three goat breeds. At P2 locus, GG, GA and AA genotypes were found in the three goat breeds. The frequencies of G allele were 0.54–0.55 and frequencies of A allele were 0.46–0.45, and the PIC was 0.37. The SNP locus was in Hardy-Weinberg disequilibrium in Boer goat breed (P<0.05). Association of polymorphisms with growth traits was done at P2 locus in Boer goat breed. The result showed that AA genotype had remarkable growth traits at P2 locus (P<0.05). Therefore, these results suggest that THRSP gene is a strong candidate gene that affects growth traits in goat.
