A study was conducted to assess the effects of replacing inorganic ‘zinc’ and ‘manganese’ with different levels of their organic complexes on growth performance and nutrient metabolizability of broilers. Experiment was conducted with 300 broiler chicks randomly divided into six groups, each consisting of 50 broiler chicks. All groups were further subdivided into five replications each containing 10 broiler chicks. The basal ration was formulated as per BIS (2007) specifications to meet energy and protein requirements of birds. In experimental groups, first group was kept as negative control (T1) containing mineral mixture without ‘zinc’ and ‘manganese’ and T2 (positive control containing mineral mixture with inorganic salts of ‘zinc’ and ‘manganese’) while experimental groups T3, T4, T5 and T6 were supplemented with mineral mixture incorporated with organic ‘zinc’ and organic ‘manganese’ @ 50 and 100% in substitution of their inorganic sources. The highest body weight gain (2334.4g) and improved FCR (1.76) in broilers was observed in T6 group which was significantly (P<0.05) better than negative and positive control groups.
