Bacterial and archaeal community compositions at different taxon levels in the rumen fluid of the goat kids across the three feeding systems. (A) The composition of bacteria at the phylum level; (B) the Firmicutes/Bacteroidetes ratios among the three feeding systems; (C) the composition of bacteria at the genus level; (D) the composition of bacteria at the species level; (E) the composition of archaea at the phylum level; (F) the composition of archaea at the genus level. The “Others” proportion represents the known and unidentified taxa with low abundances at different taxon levels.
