| Using feed additives ingredients to increase the feeding efficiency and immune response is fishes. The present study investigates the effects of varying levels of dietary fermented Aspergillus oryzae (0 g Kg-1 as control group, 10, 20 and 30 g Kg-1) on performance and hemato-immunological indices of common carp (Cyprinus carpio) fry. Common carp fry (n= 240, w= 4.56 ± 0.17 g) were supplied, randomly stocked in 12 aquaria and fed with experimentally diets for 7 week. The results revealed no significant differences between performance parameters of fermented A. oryzae fed test and control diets (P ˃ 0.05). Also, evaluation of haematological parameters (RBC, Hct, Hb) and white blood cell (WBC) counts showed no notable changes between experimental groups (P ˃ 0.05). However, respiratory burst activity was meaningfully higher in fish fed fermented A. oryzae compared control group (P < 0.05). The present results showed that possible effects of administration of fermented A. oryzae on immune responses in carp fry. | ||
