The experimental diets were added with valine by 2.7, 5.1, 8.7, 12.1 or 16.0 g/kg diet.
Values are mean of quadruplicate and presented as mean ± SD.
Values with different superscripts in the same column are significantly different (p < 0.05).
Significance probability associate with the F-statistic.
ANOVA, analysis of variance.
