Abstract

This study was performed to evaluate the antioxidant enzyme activities and determine the trace elements of carp (Cyprinus carpio) fed diets containing moderate levels of sunflower seed meal as a partial replacement of fishmeal. Four isocaloric and isonitrogenous diets were formulated with incorporation levels of 0% (control), 15%, 30% and 45% sunflower seed meal fed to triplicates group of carp. To assess the impacts of the main antinutritional constituent of sunflower seed meal, tannin, on antioxidant defense system of carp; malondialdehyde (MDA), catalase (CAT), glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) were determined in liver tissue. MDA levels enhanced significantly as a consequence of dietary treatment and represented an oxidation. CAT and SOD activities demonstrated alterations that could be considered as statistically significant (p<0.05), whereas some slight alterations in GSH-Px values were determined. Minor differences existed in the trace element levels of carp flesh independently of dietary treatment. It is concluded that dietary treatment of sunflower seed meal containing tannin leads to oxidation in carp liver by impairing the antioxidant system.
