Effects Dietary Vitamin C and Folic Acid on Growth Performance, Hematological and Immunological Parameters of Juvenile Barbel Sturgeon Acipenser nudiventris M. Naderi1;

Inroduction & This study was conducted to evaluate the effects of dietary vitamin C and Folic Acid on hematological and immunological parameters in juvenile Barbel sturgeon Acipenser nudiventris.
Material and Six practical diets were formulated as follow; control: without supplementation, T1; 200 mg ascorbic acid (AA), T2: 3.5 mg Folic Acid (FA), T3: 200 mg AA 1.5 mg FA, T4: 200 mg AA 3.5 mg FA and T5: 200 mg AA 5.5 FA equivalent kg-1 diet. Each diet was fed to triplicate groups of juvenile Barbel sturgeon with initial body weight of 32 g in 785-L cylindrical fiberglass tank.
White blood cell (WBC), red blood cell (RBC), haematocrit (Ht), haemoglobin (Hb), lymphocyte and MCV were significant. But total immunoglobulin (Ig) and IgM concentrations had significant differences between treatments. The activity of serum lysozyme was significantly influenced by the dietary AA and FA, fish fed the basal diet had lower lysozyme.
These results indicated that dietary vitamin C and folic acid (200 mg AA 3.5 mg AF) did significantly influence on hematological and immunological parameters in juvenile Barbel sturgeon.
