Investigation on Paraoxonase Enzyme Activity and Malondialdehyde Level in Liver of Oreochromis niloticus Fed with MOS Supplemented Diet

Ferbal Özkan-Yılmaz, Arzu Özlüer-Hunt, Mehmet Berköz


In this study, it was evaluated paraoxonase activity (PON) and malondialdehyde (MDA) level in liver tissue of Oreochromis niloticus fed with mannan oligosaccharide (MOS) supplemented diet. For this purpose, fish were fed commercial diet supplemented with 0.25%, 0.35% and 0.45% dietary MOS for 60 days. At the end of experiment, PON activity of liver tissue was increased in MOS groups when compared to control group. It was determined that MDA level of tissue was decreased significantly in MOS groups when compared to control group.
