چکیده

The mutual effects of zinc sulfate nanoparticles, and vitamin E nanoparticles on growth, immunological, and the hematological parameters of fingerling juvenile common carp (Cyprinus carpio) with an average weight of 9.64 ± 0.34 g were evaluated for 60 days using four different treatments (D0, diet without any zinc or vitamin E supplements, and three diets (D1, D2, D3) supplemented with normal vitamin E, zinc sulfate, vitamin E nanoparticles, and zinc sulfate nanoparticles respectively). The results showed that after 60 days of experimental feeding, in the treatment group D3, the percent weight gain (% WG, 144.56 ± 1.85), specific growth rate (SGR, 1.46 ± 0.13) and feed conversion ratio (FCR, 4.59 ± 0.68) were significantly improved compared to other groups (P< 0.05). Furthermore, the levels of total serum protein, lysozyme, immunoglobin M (IgM), cholesterol, hemoglobin, mean cell volume (MCV), mean cell hemoglobin (MCH), mean cell hemoglobin concentration (MCHC) in the treatment groups D2 and D3 were higher than other treatments (P< 0.05). White blood cells and Lymphocytes were higher in the treatment D1, D2 and D3 than treatment D0 (P< 0.05). The lowest level of cortisol, glucose, HIS and ALT belonged to the same groups (P< 0.05). The majority of the growth, immunological, and hematological parameters rose in treatment group D1 as compared to the control group, however the disparities between these groups were more pronounced. Hence, the findings demonstrate that fingerling common carp have a critical need for zinc and vitamin E, either in their natural forms or as nanoparticles.
