The present study was performed to evaluate the effects of dietary zinc-methionine (ZnMet) supplementation on broiler performance and carcass characteristics. Three added zinc levels (40, 80 and 120 mg kg-I) from each of zinc sulfate or ZnMet were used in a 2x3 factorial arrangement with four replicates of ten birds. Two hundred-forty day-old broiler chicks were fed with the experimental diets from 1 to 42 days of age and at the final day of experiment two randomly selected birds from each replicate were slaughtered and carcass parameters were measured. Inclusion of ZnMet into the diets caused to significant (p
