Response of rat mammary gland transferrin receptors to maternal dietary iron during pregnancy and lactation.

Mammalian milk iron (MFe) concentration decreases during lactation. In human attempts to increase MFe through supplementing the mother with iron during lactation have failed and no correlation between maternal iron status or intake and MFe has been determined, suggesting a regulatory mechanism. In contrast MFe in lactating rats can be affected by very high… (More)
