Abstract: An experiment was carried out to investigate the effects of zinc oxide nanoparticles (nZnO) (T1) and macro zinc oxide (ZnO) (T2) as feed additives against basal diet (control), on the growth performance, blood parameters and carcass quality of African catfish. nZnO was synthesized and characterized by X-ray diffraction and scanning electron microscopic techniques. Different levels (0.0, 0.2, 0.4, 0.8, 1.2, and 1.6 g Kg-1) of each of the treatments (T1 and T2) were supplemented to a basal fish feed and, together with the control, fed to different groups of the fingerlings for a period of 7 weeks. Fish fed control diet (C) showed significantly (p < 0.05) lower percent weight gain compared to those fed T1 and T2 diets at the end of the experimental period. T1 showed significantly (p < 0.05) higher performance as compared to T2. Protein content was significantly higher in control diet fed fish compared to those fed T1 and T2 diets, and significantly higher in fish fed T2 compared to those fed T1 diets. Fat content in fish followed the dietary sequence T1 < T2 < Control. Hematological parameters (RBCs, WBCs, Hb and Hct) increased significantly in the order Control < T1 < T2. Nano form of zinc oxide was found to be a better form of dietary zinc supplement than bulk zinc oxide.
