ND, group, normal stocking density + basal diet; ND + CGA, group, normal stocking density + basal diet +0.15% CGA; HD, group, high stocking density + basal diet; HD + CGA, group, high stocking density group + basal diet+ 0.15% CGA, group. Values with different letters within the same row are indicative of statistically significant differences (p < 0.05, Tukey’s HSD, test after one-way ANOVA).
