An experiment was carried out to investigate the effects of zinc oxide nanoparticles (nZnO) (T<sub>1</sub>) and macro zinc oxide (ZnO) (T<sub>2</sub>) 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<sup>-1</sup>) of each of the treatments (T<sub>1</sub> and T<sub>2</sub>) 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 T<sub>1</sub> and T<sub>2</sub> diets at the end of the experimental period. T<sub>1</sub> showed significantly (p < 0.05) higher performance as compared to T<sub>2</sub>. Protein content was significantly higher in control diet fed fish compared to those fed T<sub>1</sub> and T<sub>2</sub> diets, and significantly higher in fish fed T<sub>2</sub> compared to those fed T<sub>1</sub> diets. Fat content in fish followed the dietary sequence T<sub>1</sub> < T<sub>2 </sub>< Control. Hematological parameters (RBCs, WBCs, Hb and Hct) increased significantly in the order Control < T<sub>1</sub> < T<sub>2</sub>. Nano form of zinc oxide was found to be a better form of dietary zinc supplement than bulk zinc oxide. |
