title: [Effects of iron supply and lactation on iron availability in intermediate metabolism].
abstract: The availability of iron in metabolism was determined in dependence on the performance after lactation had finished and on the level of Fe-supply of a total of 56 rats. The availability of iron of those animals which had reared young was, according to the increased requirement, high and decreased from 87 to 54% after increased doses of iron. The values of full-grown control animals were considerably lower and had a falling tendency from 52 to 36% after an increasing supply with iron. Because of the reduced utilization of iron after increased supply the gross requirement must be increased over-proportionally when the net requirement rises.
