  1. The enzyme activity of maltase and sucrase were detected in the mucous of ileum, and the enzyme activity of lipase, α-amylase, and chymotrypsin were detected in the digesta of ileum. Values are expressed as the mean and pooled SEM (n = 6 per group). Different superscript letters in the same row mean significant differences (P < 0.05).
