This study investigated the effects of copper and zinc sources on growth performance, nutrient digestibility, carcass traits and meat characteristics in finishing pigs. Dietary treatments included 1) inorganic copper (CuSO4·5H2O 30 ppm), 2) organic copper (Cu-methionine, 30 ppm), 3) inorganic zinc (ZnO, 80 ppm) and 4) organic zinc (Zn-methionine, 80 ppm). ZnO treatment improved the ADFI (average daily feed intake) compared to Cu-met and Zn-met treatments (p0.05). DM and N digestibility were not significantly different among the treatments after 5 weeks (p>0.05). At the end of the experiment, DM and N digestibility were decreased with Zn-met treatment relative to the other three treatments. The pH value of meat from CuSO4 treated pigs was greater than Zn-met and ZnO treated pigs (p
