The aims of study were to evaluate the effects of polymorphisms of PIT1/RasI, H-FABP/HinfI, PIK3C3/Hpy8IandCAST/HinfIgenesand gender on carcass traits and meat quality of Vietnamese native pot-bellied pigs raised at DABACO Breeding Pig Company, Phu Tho Province, Vietnam. At 8 months of age, 23pigs (12 gilts and 11 barrows) were slaughtered to measure carcass traits (live body weight, hot carcass weight, killingout percentage, dress carcass weight, carcass yield, carcass length, backfat thickness at the vertebra prominensC7 and the last lumbar vertebra L5) and meat quality (pH value of longissimus dorsimuscleat 45 minutes (pH45) and 24 hours post mortem(pH24), drip loss percentage, cooking loss percentage, L* (lightness), a* (redness) và b* (yellowness), shear force at 24h post mortem). The polymorphisms of PIT1/RasI, H-FABP/HinfI, PIK3C3/Hpy8IandCAST/HinfIgenes were identified by PCR-RFLP technique. The results indicated that backfat thickness and L* of longissimus dorsimusclewere higherthan those in barrows(P<0.05). The polymorphisms of PIT1/RasI, H-FABP/HinfI, PIK3C3/Hpy8IandCAST/HinfIgenes did not affect carcass traits and meat quality of the nativepigs.
