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

The existing trial investigated the effects of supplementing the diet of Nile tilapia with BergaPur (R) 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 (R), 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 (R) groups. Also, AST and ALT levels decreased significantly (P < 0.05), while glucose levels increased significantly (P < 0.05) in BergaPur (R) groups at all sampling points. Immune (phagocytosis and lysozyme activity) and antioxidant (SOD, GPx, and CAT) parameters increased significantly (P < 0.05) in BergaPur (R) 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 (R) on the hematological, immune, and biochemical parameters of O Oreochromis niloticus, with a suggestive concentration of 2 g/kg diet.
