| The effect of different levels of hydroalcoholic extract of Ziziphora clinopodioides (ZE) on serum biochemical parameters, liver enzyme activity and antioxidant defense of rainbow trout was investigated. The fish (n=450) with an average weight of 21.19 ± 1.09 g were distributed in 15 tanks and fed with different levels of ZE extract in five treatments including 0 (control), 0.5, 1.5, 3 and 4.5% were for 8 weeks. The results showed that administration of ZE at all levels except 0.5% increased catalase activity (P <0.05). Serum biochemical parameters showed that dietary supplementation with concentrations of 3 and 4.5% significantly reduced glucose, cholesterol and cortisol levels (P <0.05). Meanwhile, the highest amount of albumin was recorded in fish fed with dose of 4.5%, which showed a significant difference with other groups except 3% (P <0.05). Examination of liver enzymes showed that the levels of liver enzymes in response to a diet containing 3% ZE showed a significant decrease compared to 0.5% and the control group. The supplementation of the diet with 3% ZE resulted in a significant improvement in the activity of superoxide dismutase (77.72 ± 2.09 u/ml) compared to fish belonging to 0.5 and 1.5 treatments and the control groups (P <0.05). Also, the amount of malondialdehyde (2.70 ± 0.25 nM/ml) and glutathione peroxidase (0.38 ± 0.08 U/ml) were significantly changed in the group fed with 3% ZE. ZE at 3% improved the serum biochemical metabolites and antioxidant capacity in rainbow trout. |
