The effects of dietary tributyrin (TB) on growth, intestinal health, inflammatory response and antioxidant status in juvenile Pelteobagrus fulvidraco were investigated. The fish (initial weight 5.53 ± 0.02 g) were fed with diets containing 0 (control, TB0), 500 (TB1), 1000 (TB2) and 2000 (TB3) mg/kg tributyrin for 56 days. The results showed that significantly higher final weight, specific growth rate, protein efficiency ratio and protein retention were observed in fish fed with TB2 diet compared with those in TB0 (P
