Rarefaction analysis of V3 16S data from canine fecal samples.
(A) Dogs fed a low-fiber control diet. (B) Dogs fed a diet supplemented with beet pulp fiber. Each line represents a single animal or a pooled sample. Analysis was performed on a random 2,000- sequence subset from each sample. Operational Taxonomical Units (OTU) in this analysis were defined at 96% similarity.
