Determination of Iron Absorption Using Two Isotopes of Iron

Abstract
A method is described whereby Fe absorption may be measured by using 2 isotopes of Fe and compared with total-carcass recovery studies. The accuracy of this method is unaffected by a variety of exptl. conditions which might be expected to influence Fe metabolism. In animals with hemolytic anemia, bone marrow damage, turpentine abscesses and increased Fe stores, Fe absorption was uniformly reduced.
