Principal component analysis (non-dimensional scaling) on microbial sequences from NGS. 3D clustering patterns of individual animals within each diet treatment by age. Black (ABX), grey (NABX) and white (COC) denote diet treatment. a d24 of age. b d31 of age. c d45 of age. d d71 of age. Spatial proximity of each dot indicates the similarity of one individual’s microbial communities to another individual’s microbial communities. The closer dots are the more similar samples are and the farther dots are the less similar samples are
