Effect of vitamin E inclusion in diets of hybrid catfish (Heteroclarias) juveniles on its growth, feed Utilization, hematological responses and immunological response was examined. Three levels of vitamin C supplemented diets with 60 (T1), 120 (T2), and 180 (T3) vitamin E equivalent and a control basal diet without vitamin C were fed to Heteroclarias juveniles (triplicate group) twice daily for 12 weeks. Result showed that growth parameters, feed utilization efficiency values, haematological and immunological parameters of the treatments groups when compared to control (vitamin E depleted diet), increased significantly (p<0.05). Furthermore, growth, heamatological and immunological parameters increases as inclusion level of dietary vitamin E increases. Therefore, inclusion of up to 150 vitamin E in diets may be beneficial for the optimal growth and survival of hybrid catfish.
