Abstract

The polymorphisms of DGAT2 gene in 92 Jiaxian red cattle were analyzed using PCR-RFLP method. Results showed that the PCR products digested with TaqI demonstrated polymorphisms, and showed two kinds of genotype: AA and AB. This polymorphic locus of DGAT2 gene was at Hardy-Weinberg equilibrium (P>0.05). The results of general linear model analysis showed that polymorphisms of DGAT2 gene had significant association (P<0.05) with body weight and body length, while had no significant association with others growth traits (P>0.05). Therefore, genotype AB may have positive effect on body weight.
