To investigate the effect of probioenzyme on growth, nutrition, hematology and immune response in
rainbow trout (Oncorhynchus mykiss),this matter was supplemented at 0.3, and 0.5g/kg diet(treatments
of 2 and 3 respectively) and control group(treatment 1: no food supplemented probioenzyme) in three
treatments with three replications. This survey was performed in nine 200ltanks containing 30
fish(average weight: 26.3± 2.7g) in each tank for 60 days. At the end of the feeding period, the growth
and blood factors analyzed. Based on the results, there is no significant difference between treatments
1, 2 and in growth, nutrition and blood erythrocytes factors(P >0.05). The mean white blood cells and
blood cells neutrophil percentage in treatment of 3 was significantly different (P <0.05) from the control
group fish. Significant differences in serum complement components in the treated groups were in
comparission to control group (P <0.05). ACH50 activity and immunoglobulin (IgM) did not show
significant differences between treatments (P> 0.05). The lysozyme and serum globulins in treatment 3
compared to the control treatment was higher and statistically significant (P <0.05). Although there
weren,t signs of significant effects of probioenzyme on growth and nutrition factors, Probioenzyme can
have immunological effects on rainbow trout.
