and no difference was detected between EFMD and SDPPD in performance (Table 5). This indicates EFM is a promising alternative
animal protein source for nursery piglets to replace DPS or SDPP without compromising performance. It has been proposed
that the greater VFA concentration in the colon may provide a driving force for water and sodium absorption from the colonic
lumen (Roediger, 1994; Pierce et al., 2007), which can subsequently increase stool consistency (Argenzio and Whipp, 1979;
Cummings and Macfarlane, 1991). In the current study, the lower fecal score in EFMD on d 0–14 may be supported by the
greater VFA concentration in colon (Table 8).
