When the determined fiber
digestibility of a kiwifruit-containing diet was corrected for this
IM, observed negative digestibility values, which are untenable
physiologically, largely disappeared. Furthermore, determined
digestibility markedly underestimated the corrected digestibility
of SDF at the ileal level and that of IDF over the entire
gastrointestinal tract; therefore, it is important that the correction
for IM be made when determining the digestibility of DF
