Interactions between MUC4 gene polymorphism and diets on pH values, total short-chain fatty acids (SCFA), valerate molar ratio, and branched-chain fatty acids molar ratio (BCFA) on day 8 PI. CTR+: non-inoculated animals receiving placebo; PRO−: inoculated animals receiving the probiotics; PRE−: inoculated animals receiving the prebiotic; SYN−: inoculated animals receiving the synbiotic; CTR−: inoculated animals receiving placebo. N = 6 for all groups except for non-challenged animals (N = 8). MUC4 represents the effect of polymorphism of the MUC4 gene. a and b indicate statistically significant differences between groups. Bars correspond to standard error. BCFA, branched-chain fatty acids; MUC4+, Mucin 4 susceptible genotype; MUC4−, Mucin 4 resistant genotype; SCFA, short-chain fatty acids.
