Eight weeks of feeding trial was conducted to investigate the effects of dietary supplementation of microencapsulated sodium butyrate (MSB) on juvenile black sea bream ( Acanthopagrus schlegelii ). A basal diet was designed with 24% fish meal, and the other four diets were formulated with dietary supplementation of graded levels of MSB at 0.05%, 0.10%, 0.20% and 0.40%, respectively. Triplicate tanks were randomly assigned to each diet with 20 fish having an initial weight of 9.98 ± 0.13 g. The weight gain rate, specific growth rate and feed efficiency ratio of fish fed the MSB 0.2% diet were significantly ( p < .05) higher compared to the control group. Proximate compositions of the whole body and dorsal muscle were non‐significantly different among the groups ( p > .05). The apparent digestibility coefficients of dry matter, crude protein, and crude lipid were significantly higher in the MSB‐supplemented treatments ( p < .05). The contents of total protein, cholesterol and albumin in serum were non‐significantly different in all groups ( p > .05). The superoxide dismutase activity, immunoglobulin M content and total antioxidant capacity were significantly ( p < .05) higher in the group fed with MSB‐supplemented diets compared with the control group. The villus height and the number of goblet cells per villus in the fore intestine were significantly ( p < .05) higher in the group fed with MSB‐supplemented diets. From the present study, we concluded that MSB‐supplemented diet enhances fish growth and its intestinal health.
