The present study was conducted to evaluate the effect of supplementing organic source of Zinc (Zn) and Manganese (Mn) on growth performances of broilers chicks. One hundred and twenty days old unsexed broiler chicks were randomly assigned to four dietary treatments with three replicates and 10 birds per each replicate. The experimental birds were fed with the following four diets. The control diet (T1) was formulated by incorporating inorganic Zinc and Manganese. For each of the treatments, inorganic Zinc and Manganese diet of the control diet were added by organic (Methionine base) Zinc and Manganese at 100% of the recommended level (T2), 80% of the recommended level (T3) and 70% of the recommended level (T4). There was no significant difference in body weight, feed consumption and feed efficiency between organic and inorganic source fed Zinc and Manganese groups.
