Dietary BergaPur® supplementation enhanced the hematological, immune, biochemical, and antioxidative reactions of Nile tilapia, Oreochromis niloticus

Abstract The existing trial investigated the effects of supplementing the diet of Nile tilapia with BergaPur ® on the hematology, immune response, biochemical factors, and antioxidative capacity. Four groups of fish with an average weight of 10.0 ± 0.5 g received BergaPur ® , de-oiled phospholipid complex at a rate of 0 (control), 1.0, 1.5, and 2.0 g/kg diet for 9 weeks. Sampling included blood, serum, and liver samples from the four groups at the end of each 3 weeks for a 9 weeks total experimental period. Hematologic readings, serum biochemical, and oxidative parameters were investigated. Findings included a significant ( P < 0.05) hematology augmentation (corpuscular Hb, packed cell volume, leukocytic, monocytic, and lymphocytic counts), and a remarked increased ( P < 0.05) serum proteins (albumin, globulin, and total) were recorded in BergaPur ® groups. Also, AST and ALT levels decreased significantly ( P < 0.05), while glucose levels increased significantly ( P < 0.05) in BergaPur ® groups at all sampling points. Immune (phagocytosis and lysozyme activity) and antioxidant (SOD, GPx, and CAT) parameters increased significantly ( P < 0.05) in BergaPur ® supplemented groups, compared to the control, while MDA level decreased obviously in the incorporated groups over the control. Our findings verified the positive effects of BergaPur ® on the hematological, immune, and biochemical parameters of O Oreochromis niloticus , with a suggestive concentration of 2 g/kg diet.
