Abstract: A study was conducted to evaluate the effect of replacing inorganic zinc with organic zinc (Zn-methionine) on the performance, carcass characteristics and organ weights of commercial broiler chicken for a period of 6 weeks. A total of 150 day old chicks were selected and randomly divided into five dietary groups with three replicates containing 10 chicks in each replicate. The dietary treatments includes corn-soybean based basal diet as control (T1) or the basal diet supplemented either with 40 or 80 mg of Zn/kg of feed from Zn oxide (T2 and T3) and Zn-methionine (T4 and T5), respectively. There was a significant performance difference exist among the treatment groups fed with zinc oxide and Zn-methionine at different levels. The result of this experiment showed that the zinc oxide and Zn-methionine had a same effect on body weight and weight gain, but zinc oxide at 40 mg/kg significantly (p<0.05) increased feed consumption and had better feed efficiency. Carcass traits were not influenced by the experimental supplements. Hence, it can be concluded that replacing 50% organic source of Zn was relatively economical and can be used without any negative effects either on performance or on the environment.
