a
Significant pairwise comparisons identified (P < 0.05).
b
For each age group the influence of dietary supplementation with antimicrobials on the gut microbiota was investigated. Where significant differences in the gut microbiota were identified, the significant pairwise differences between dietary treatments are listed.
