Comparison of similarities in microbiota composition between the three treatments by ANOSIM analysis.

Treatment	R-value	P-value
CTL-CP	0.6735	0.002
CP-ARGCP	0.3635	0.009
CTL-ARGCP	0.2828	0.021

The value of R ranges from −1 to 1. The groups are significantly different when the R-value is >0, and the intra-group difference is greater than the inter-group difference when the R-value is < 0. P < 0.05 indicates a significant difference. CTL, non-challenge control; CP, C. perfringens-challenged group; ARGCP, C. perfringens-challenged group fed diet supplemented with 0.3% l-arginine.
