Mean values with their SEM; n=6.

a-c

Mean values with unlike superscript letters were significantly different, P<0.05 (Tukey post hoc test for fecal weight, fecal Bacteroides, cecum weight, cecal digesta weight, cecal pH; Steel-Dwass test for fecal Lactobacillus spp., fecal Clostridium coccoides, fecal Bifidobacterium spp., cecal microbiota and cecal organic acids). HSR, high-starch; HSC, high-sucrose; PA, sodium phytate; SEM, standard error of the mean.
