Abstract: The present study was planned to investigate the possible effects on the growth, feed conversion ratio and nutrient metabolizability of broiler chickens when supplemented with different sources of zinc. One hundred and sixty day-old broiler birds were equally and randomly distributed into four treatment (T1, T2, T3 and T4) groups which subdivided into four replicates containing ten birds in each, reared on deep litter system up to 6 weeks of age. T1 group was kept as control and offered maize-soybean meal based diet without any source of zinc in mineral mixture. Treatment groups T2, T3 and T4 were supplemented with inorganic zinc, organic zinc and nano zinc, respectively. Nano zinc oxide fed groups had significantly (P< 0.05) higher average feed intake as compared with control group. Average body weight gain and feed conversion ratio in T4 group were significantly (P<0.05) higher as compared to other treatment groups. It was observed that the nutrient metabolizability in terms of dry matter metabolizability, nitrogen retention and gross energy metabolizability increased significantly (P<0.05) in the diets having nano zinc oxide compared to other groups. The results of the present study suggested that the dietary inclusion of nano zinc in broiler diets replacing either inorganic or organic zinc from mineral mixture was found to improve growth performance along with nutrient metabolizability in broiler chickens.
