compared to control diet (CON). In ileum, increased
villus height (P < 0.05) was found in pea fiber diet (PF) and wheat bran fiber diet (WB)
compared to soybean fiber diet (SF). Higher ileal sucrase (P < 0.05) and maltase activities
(P < 0.05) occurred in pigs fed PF compared to CON and SF. In cecum, acetate concentrations
in SF (P < 0.05) and butyrate concentration in WB (P < 0.05) were higher than those in CON.
Lower ileal Lactobacillus populations (P < 0.05) and higher cecal Escherichia coli populations
in SF (P < 0.05) were found compared to CON. Meanwhile, cecal Lactobacillus populations
in PF (P < 0.05) and Bifidobacterium populations in WB (P < 0.05)
