| Aloe vera has been used worldwide both for pharmaceutical, food and cosmetic industries due to the
plethora of biological activities of some of its constituents. The aim of this study was to evaluate the
effects of Aloe vera on the antioxidant defense and growth index in rainbow trout. 480 Rainbow trout,
weighing 9.50 gr were divided into four group, group 1: normal group, group 2: 0.5 mg/kg Aloe vera
concentration, group 3: 1 mg/kg Aloe vera concentration, group 4: 2 mg/kg Aloe vera concentration.
Serum catalase, superoxide dismutase, glutathione peroxidase and growth index were estimated. Our
results showed that growth was not significantly affected by Aloe vera extract. In experimental control
groups, 0.5 and 2 concentration enzyme activities were significantly lower compared with control group.
In conclusion, Aloe vera is not recommended for strengthen of antioxidant defenses. |
