 Fish were fed for 60 days with three experimental diets (C, B, and T), which contained the same low percentage of fishmeal and high percentage of soybean meal. Diets B and T were supplemented with 0.2% of sodium butyrate or taurine, respectively, whereas Diet C (control), was not supplemented. Values are mean ± SD (n = 10). Statistical differences were calculated by twoway ANOVA followed by Duncan's post hoc test. The values in each row with different superscript letters are significantly different (P < 0.05)
