Asimi OA and Sahu NP

The present study was conducted to evaluate the protective effect of clove (Cl) and cardamom (Cd) extracts as natural antioxidants in the diet of Labeo rohita fingerlings. Both the spice extracts were mixed separately or in combination at the level of 0.5 and 1.0%. Thus, seven experimental diets were Cl-0.5, Cl-1.0, Cd-0.5, Cd-1.0, CC-0.5 and CC-1.0 and control with no extract. The results revealed that, SOD and CAT activities were significantly (p<0.05) higher in Cl-0.5 compared to the control. AST, ALT, LDH, MDH, G-6-Pase, activities in liver and muscle decreased significantly (p<0.05) in all treated groups. Significantly (p<0.01) lowest activity was observed in treatment group fed with clove extract (0.5%) as compared to the control. The results suggest that the dietary administration of clove extract supplementation at a concentration of 0.5% level possess good anti-stress activity.
