Intestinal histology of gastrointestinal tract of L. fimbriatus fingerlings fed diets supplemented with fructooligosaccharide (FOS) and B. subtilis (BS) alone or in combinations for 60 days. (A) FOS (0.5% level), (B) Low BS(LBS) (104 CFU/g BS), (C) FOS + LBS, (D) High BS (HBS) (106 CFU/g BS), (E) FOS + HBS and (F) Control (No FOS, NO BS i.e. without BS/FOS). BS and FOS interactions effect are presented in the chart and bars sharing same small letter alphabet are not significantly different (p > 0.05). Main effects (FOS and B. subtilis) from Two-way ANOVA are presented in the results section. Significance of all tests was accepted at p = 0.05. Lu, lumen; Mu, Mucosa; Sb, Submucosa; ML, Muscularis; V, Absorptive vacuoles; lp, lamina propria; e, epithelial layer; goblet cell (arrowhead).
