Abstract: Retinoic acid receptor-gamma（RARG）gene was studied as a candidate gene for the prolificacy of Small Tailed Han sheep. The single nucleotide polymorphism of RARG gene in both high fecundity breeds (Small Tailed Han and Hu sheep) and low fecundity breeds (Texel，Dorset and Suffolk sheep) was analyzed by PCR-SSCP. There was PCR-SSCP polymorphism for primer 1 in five sheep breeds. AA genotype was only detected in Hu sheep, AB and BB genotypes were detected in five sheep breeds. The ewes with genotype BB had 0.41 (P>0.05) lambs more than those with genotype AB in Small Tailed Han sheep. There was PCR-SSCP polymorphism for primer 2 in five sheep breeds. CC and CD genotypes were detected in five sheep breeds. The ewes with genotype CC had 0.55 (P<0.05) lambs more than those with genotype CD in Small Tailed Han sheep.
