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). Values of p were obtained by an ANOVA using the generalized linear procedure in R software. a,bIndicate statistically significant differences between groups. CFU, colony forming units; PI, post-inoculation; RSD, relative standard deviation. To differentiate RSD and values of p from the results numbers, they are in italics. *indicates that values of p are <0.05 and statistical difference is present.
