The research was conducted at the poultry farm in Kharabo, Faculty of Agriculture, Damascus University. 1080 chicks of Lohman hybrid, one day old, distributed randomly and equally into six different groups, G1….G6 (180 chicks/ group) with three replicates in each group (60 chicks per replicate). Chicks in all groups were fattened for 42 days on Diets composed of vegetarian feeding stuffs, based on corn, soya bean meal and different additives. Chicks of G1 were fed on the main diet without adding iron or copper. The chicks in G2 and G3 were fed on the main diet mixed with 80 and 160 ppm of iron respectively. The vhicks of G4 were also fed on the main diet mixed with 8 ppm of copper. The Chicks of G5 and G6 were fed on the main diet mixed with iron and copper (80 and 8 ppm) and (160 and 8 ppm), respectively. Results demonstrated that adding iron and/or copper to the broiler diet was safe for chickens up to 42 days of age and did not affect significantly on carcass parameters. Supplementation of broiler diet with 8 ppm of copper was not associated with accumulation of copper in the tissues of liver, leg bone, breast, and thigh. Adding 80-160 ppm of iron to the broiler diets was not associated with high level of accumulation of iron in the tissues of breast and thigh but with high concentrations (p < 0.05) in the tissues of liver and leg bone.
