摘　　要：[ Objective] To investigate the relationship between muscular malic enzyme （ME） activity and meat quality in pigs. [ Method] Three pig breeds, Exi pigs, Changye x Exi hybrid pigs and Landrace xYorkshire pigs were selected. Then the ME activity and meat traits were detected, and the relationship between ME activity and meat quality were analyzed with SAS software. [ Result] The Exi pigs had the highest ME activity and intra- muscular fat （IMF） content （ P 〈 0.05）. The pH2 value, drip loss and muscle shear force of Landrace xYorkshire pigs were higher than that of Exi pigs significantly （P 〈 0.05）. [ Conclusion] The ME activity has a certain correlation with meat quality of pigs. The muscular ME activity has signifi- cantly positive correlation with IMF content and significantly negative correlation with drip loss and muscle shear force.[ Objective] To investigate the relationship between muscular malic enzyme （ME） activity and meat quality in pigs.
