Non-metric multi-dimensional scaling plots. Plots depict community terminal restriction fragment (T-RF) presence/absence (A) and T-RF relative abundance (B) within the small intestine of control and AS700 treatment cattle. All locations consist of five replicate animals, with the exception of digesta from the distal jejunum for control treatment cattle (n = 3), and from the ileum of control and AS700 treatment cattle (n = 3). Each marker represents a bacterial community for one sample. Ellipsoids represent predominant clustering of digesta relative to mucosa-associated communities.
