Quantität und Qualität des Milcheisens

Milk iron and its metabolism in the lactating rat

“…The present results show no relation between milk iron and plasma iron. Similar results were found in man by Neuweiler (1952) and by Schafer et al (1955) when a large increase in plasma iron produced by administration of iron did not result in an increased milk iron. Ekman et al (1958), however, demonstrated a small, statistically significant relationship, but only when the results were taken as a group.…”

“…Iron status of the sucklings and the nutritional significance of milk iron The nutritional adequacy of rat milk with regard to iron, as reflected in the total body iron content of the suckling, is difficult to assess since this depends on the content and availability of iron in milk and the ability of the sucklings to absorb it. Schafer et al (1955) consider that the absorption of iron from milk might be impeded by its high phosphate content.…”

“…An analogous marked decline in milk iron concentration has been observed in the quokka (Kaldor & Ezekiel, unpublished). On the other hand, the magnitude of changes in iron concentration in human milk is small and it is not certain what pattern the variation takes (Wallgren, 1932;Albers, 1941;Neuweiler, 1952;Schafer, 1955;Fabiano, 1956). This also applies to the sow (Venn, McCance & Widdowson, 1947) and the dairy animals (Trunz, 1903;Elvehjem, Herrin & Hart, 1926;Praphulla & Anantakrishnan, 1959).…”
