Smaples of blood plasma (n = 6 per treatment) were analyzed for the concentrations of gut hormones and immune indices on the trial of day 28. The results were presented as mean values ± SEMs. Data were analyzed by student’s t-test. Statistically significant differences are annotated with different letters P < 0.05. CON, control group; CB, corn bran group; GLP1, glucagon-like peptide 1; PYY, peptide YY; 5-HT, 5-hydroxytryptamine; IgA, immunoglobulin A; IgG, immunoglobulin G; IgM, immunoglobulin M; TNF-α, tumor necrosis factor α; IL-1β, interleukin 1β; IL-6, interleukin 6; IL-10, interleukin 10.
