From: Evolution of rumen and oral microbiota in calves is influenced by age and time of weaning
Principal coordinates analysis plots depicting the distribution of bacterial communities in 233 samples collected via two different sampling methods (buccal swabbing (BS) and stomach tubing (R)) from different age group calves, without exclusion (a) or after exclusion (b) of potential oral taxa by mathematical filtering approach. Each point represents one sample. Different age groups are indicated by different coloured triangles
