Total VFA concentration tended to be higher in the cecum (P = 0.09) and colon (P = 0.08) of pigs fed EFMD in comparison
with the other treatments (Table 8). In the cecum, the ratio of acetate to total VFA was lower (P < 0.05), and the ratio of
propionate to total VFA was higher (P < 0.05) in EFMD group than in other groups. In the colon, the ratio of acetate to total
VFA tended to be lower (P = 0.09), and the ratio of valerate to total VFA was higher (P = 0.03) in EFMD comparing with other
treatments. There were no significant differences in the VFA concentration of digesta in the rectum among the treatments.
