Abstract: The experiment was conducted to determine the effect of dietary sodium butyrate on the feeding,growth performance,and Antioxidant capacity of Anguilla rostrata.There were three groups.The diet of Control group,experimental group I,experimental group II contained 0‰,0.5‰ and 1.0‰ of sodium butyrate,respectively.Each experimental group was divided into 2 parallel groups and stocked in indoor tanks(100 Anguilla rostrata /1m3).The experiment lasted 42 days.Daily food intake was recorded during the experiment.Fish weight and liver antioxidant capacity were determined at the end of the experiment.The results showed that,in the weight gain and reducing feed conversion ratio,both of the experimental groups were better than the control groups.Compared with the control group,weight gain of experimental group Ⅱ increased by 37% and feed conversion ratio of experimental group Ⅱ decreased by 26%.In feeding rate and survival rate,the three groups did not differ significantly.Compared with the control group,liver total antioxidant capacity and catalase activity of experimental group Ⅱ were increased by 25% and 15%,MDA was decreased by 15%,while the experimental groupⅠhad little difference.

Key words: sodium butyrate, feeding, growth performance, antioxidant capacity, Anguilla rostrata
