absorption in the upper small intestine and most of the
Fe in the feces represents unabsorbed dietary Fe (IOM,
2001). The reason pigs fed the diets containing FeGly had
greater retention of Fe than pigs fed FeSO4 is that FeGly
is better digested and absorbed by the pigs compared with
FeSO4. These results are in close agreement with data
from Burkett et al. (2009), who reported that fecal Fe excretion
is reduced if pigs are fed peptide-chelated Fe compared
with pigs fed FeSO4. Iron glycinate also has a greater
ATTD of Fe than Fe from FeSO4 when fed to weanling
pigs (Ettle et al., 2008). Iron from a Fe-AA complex has
also improved absorption from the duodenum compared
with FeSO4 (Yu et al., 2000). As was the case with Cu and
Mn, the difference between organic and inorganic microminerals
was reduced when they were added to the corn
