| The potential use of dietary probiotics to enhance the immunity and health of aquatic animal’s hasrecently attracted intensive attention. The purpose of this study was to investigate the effect of different levels of Saccharomyces cerevisiae yeast on blood serum enzymes (aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP)) and antioxidant systems (Superoxidase dismutase (SOD), Glutathione peroxidase (GPX), Malondialdehyde (MDA) catalase (CAT)) in grey mullet, Mugil cephalus for 60 days. This experiment was designed as a completely random design in four treatments and each in three replicates. S.cerevisiae was added to the basic food in three rations of 2, 4 and 6 %, of the food weight. Also a treatment without S. cerevisiaewas chosen as control. Grey mullet with an initial weight of 5.56g were randomly distributed on 12 fiberglass tanks of 60Ll with twenty fish in each tank. At the end of the experiment, the results showed that the highest activity of CAT, SOD, and the lowest activity of ALT, ALP enzymes and MDA level were observed in group containing 6% of yeast that had significant difference with other treatments (P<0.05). The results of this study showed that S.cerevisiae yeast had desirable effects on the amount of serum enzyme activities and antioxidant systems of liver of M. cephalus |
