Figure S1: Rarefaction curves of animals fed with antimicrobial-supplemented diet (AB) and unmedicated diet (UN) depending on age (prestarter I [PI] at 9 days post-weaning, starter [S] at 40 days post-weaning, and fattening [F] at 72 days post-weaning). Table S1: Differential abundance of minor phyla (< 1.0%) between treatments, ages, and their interaction. Table S2: Differential abundance of minor families (< 1.0%) between treatments, ages, and their interaction. Table S3: Differential abundance of minor genera (< 1.0%) between treatments, ages, and their interaction.
