Comparison of the gut community composition. (A) Principle coordinate analysis (PCoA) plot generated based on the calculated distances in an unweighted UniFrac matrix. Samples were grouped by color and shape in terms of diet group they belong to; alginate-containing diet (ALG) red (circle), control diet (CON) blue (square), and resistant starch-containing diet (RS) orange (triangle). Labels contain name of diet type (CON, ALG, RS), pig number for the specific diet with numbers between 1 and 3, and time-point numbers between 1 and 7 in the order (starting from T1 as first time-point). (B) The statistical significances of differences in unweighted UniFrac distances between diets. Significance degree (calculated using Student’s t-test with 1,000 Monte Carlo simulations) is represented as no significance (P > 0.05) with NS; P < 0.05 with one star (*); P < 0.005 with two stars (**).
