Abstract


This study was conducted to analyze the genotypes and genes of FABP3 (Fatty-acid Binding Protein 3) in pigs using MSPI restriction enzyme and electrophoresis. Analysis of data collected from a total of 210 crossbred pigs (LYD or YLD) in Chungcheongnam-do, Korea, revealed the following. The AA genotypes of FABP3 were detected in the 750 bp and 100 bp bands,while the Aa heterotype appeared in the 850, 750 and 100 bp bands and the aa recessive homotype was detected in a single band of 850 bp. The genotype frequency of AA, Aa and aa was 46.67%, 51.43% and 1.90%, respectively. The genetic equilibrium of this population showed a significant difference (p<0.001) based on a χ2-test. The carcass weight, backfat thickness,marbling score, pH, drip loss, cooking loss, and meat color based on the CIE L*, and b* values according to genotypes of FABP3 did not differ significantly (p>0.05); however, the CIE a* values did (p<0.05).
