Cecal content weight, pH of cecal contents, and total SCFAs in cecal content of rats fed the control, S-IMO, L-IMO, or Dex diet.

Values are expressed as means ± SEM (n = 6–7). Significant differences of the values the rats with or without 2% DSS treatment in each diet group (P<0.05) were determined by an unpaired two-tailed Student’s t-test (*P<0.05, **P<0.01, ***P<0.001). Significant differences of the values against control group in each treatment (P<0.05) were determined by Dunnett’s multiple comparison test (†P<0.05, ††P<0.01, †††P<0.01).
