Effects of herbal supplements and inulin on activity of antioxidant enzymes in juveniles of Common Carp (Cyprinus carpio)

In this study, the effects of onion powder, savory and inulin (prebiotic) in different treatments containing control group, treatment of 1% inulin, treatment of 1% savory powder, treatment of 1% onion powder and treatment of 1% a mixture of savory and onion powder (each one in the amount of 0.5%) in triplicate on some activities of antioxidant enzymes and blood parameters of juvenile carp were examined for 45 days. In each 300 liter water tank 10 fish with initial average weight of 19.96 ± 0.08 gr were storage. Experimental fish were fed to satiation triple daily. At the end of the period, the activity of antioxidant enzymes (Superoxide dismutase, Glutathione peroxidase, Glutathione reductase), malondialdehyde (MDA) value as an indicator of lipid peroxidation in blood plasma of fish and blood factors (hematocrit, hemoglobin) were evaluated. The results showed that the activity of antioxidant enzymes increased in all treatments compared with control group which is significantly different in herbal treatments (p
