Values within a column followed by different superscript letters differ significantly (P < 0.05). CTL, non-challenge control; CP, C. perfringens-challenged group; ARGCP, C. perfringens-challenged group fed diet supplemented with 0.3% l-arginine. VH, villus height; CD, crypt depth; VCR, the ratio of VH:CD. Data are shown as the mean ± standard error.
