Abstract

Digestarom® P.E.P. MGE contains a standardized mixture of phytogenic essential oils. The aim of this study was to investigate the effect of Digestarom dietary supplement on liver enzymes as well as antioxidant properties of this supplement on common carp. In this study, the effect of dietary Digestarom supplement was investigated in three groups, including a control one without Digestarom, the second group containing 200 mg/kg of Digestarom, and the third group with 400 mg/kg of Digestarom on 225 common carps with a mean weight of 16.15 ± 2.98 g for 60 days. After the experiment, sampling of fish was carried out on day 60. Then the growth performance, activity of blood plasma oxidative and liver enzymes was studied. Based on the results, administration of Digestarom has led to improve in growth parameters especially at the level of 200 mg/kg. The results of the experiment did not show significant difference in the level of superoxide dismutase (SOD), catalase (CAT) and glutathione (GSH) and malondialdehyde (MDA) between the treatments and the control group (P<0.05). Comparison of liver enzymes levels such as AST, ALT, ALP and LDH between the treatments and control group showed that despite of changes in the level of these enzymes between the groups, only the ALP significantly increased in the group 2 compared to group 3 and control group (P<0.05). Based on the results, suplemnting Digestarom in above-mentioned levels probably has a positive effect on growth performances without any negative effect on the liver and antioxidant enzymes in common carp fingerlings.
