Fig. 2. Effects of graded levels of CHC on the intestinal mucosa SIgA and MDA levels in weaned piglets (n = 6). *Represents a significant difference between groups (P < 0.05), **represents a significant difference between groups (P < 0.01). CHC, 500, 1000, 1500 and 2000 indicate the amount of CHC added as a dietary supplement, i.e., 500, 1000, 1500 and 2000 mg kg−1 of CHC per group, respectively.
