Fig. 1From: Low-protein diets supplemented with casein hydrolysate favor the microbiota and enhance the mucosal humoral immunity in the colon of pigsPrinciple-coordinate analysis (PCoA) of bacterial community by unweighted UniFrac distance (a) and distribution (%) of bacteria at phylum level (b) in the colon of pigs. In a, each point corresponds to an individual animal, and the percentage of variation explained by PC1 and PC2 are indicated in the axis. LPA: Low-protein diets supplemented with free amino acids.
