Fig. 2.

Microbial species abundance profile of the piglet gut over time. Panels represent time points from t0 (piglets aged 3 to 4 weeks old) to t10 (piglets aged 8 to 9 weeks old). Samples were pruned (exclusion of samples with approximately <10 000 read counts) and normalized by rarefaction. Prior to plotting, taxa were filtered to include the most abundant taxa present in at least 20 % of the piglet samples. Of these, the 35 taxa with the highest variance among samples were plotted. Analysis was performed with PhyloSeq.
