Abstract
An 8-week growth trial was carried out in freshwater fiberglass tanks to investigate the effects of different dietary prebiotic inulin levels on hematologic and biochemical parameters and some blood serum enzymes in juvenile great sturgeon (Huso huso). Four experimental diets were formulated to contain different prebiotic inulin levels (0.0%, 1.0%, 2.0%, and 3.0%, respectively). Triplicate groups of fish (50 fish per tank with an average body weight of 16.14 ± 0.38 g) were assigned to each diet. Blood samples were taken from the caudal vein of 60 apparently healthy fish at the end of the trial. No significant differences were observed in serum enzymes between the treatment groups (P > 0.05). The results show that with the increase in supplementation level of inulin, the mean values of alkaline phosphatase decreased but the mean value of other enzymes increased. white blood cell count increased significantly in group treated with 1% inulin compared with the other groups (P < 0.05). No significant difference between the treatment groups was observed in some hematologic and biochemical parameters such as red blood cell count, mean corpuscular hemoglobin (MCH), and glucose (P > 0.05). With the increase supplementation level of inulin, the mean values of cholesterol, MCH, and MCH concentration increased, but the mean value of glucose, white blood cell count, red blood cell count, hematocrit, hemoglobin, and mean corpuscular volume decreased.
