Values are mean of triplicate groups (n = 3) and presented as mean ± SD.
Values with different superscripts in the same column are significantly different (p < 0.05).
Apparent digestibility coefficient of dry matter (%).
Apparent digestibility coefficient of protein (%).
Apparent digestibility coefficient of lipid (%).
Con, basal diet; TB, tributyrin; TB5, TB10 and TB20 are 0.05%, 0.1% and 0.2% TB supplemented diets; ANOVA, analysis of variances.
Probability value associated with the F-statistic. Values < 0.05 indicate significant differences among treatments.
