Taxonomic composition at phylum level in the rumen microbiome of calves at weaning (T1), backgrounding (T2–T3), and finishing (T4–T5). a Barplot showing the relative abundance of phyla at weaning, backgrounding and finishing. b Boxplots showing relative abundances of Proteobacteria in calves within every BKG system, from weaning to finishing. c Boxplots showing relative abundances of Proteobacteria in calves within specific time points, BKG:T2–T3 and finishing: T4–T5.
