1. The retention of iron from different sources by anemic ratswas qualitatively and quantitatively similar irrespective ofwhether the iron salts were fed as such or contained in bread.
2. The various iron compounds tested showed the followingorderof effectiveness with respect to the relative degree ofironretention and hemoglobin regeneration produced in anemicrats:ferric chloride > sodium ferric orthophosphate = ferricphosphate> reduced iron > sodium iron pyrophosphate.
3. Prevention of anemia in milk-fed rats given supplementsofferric chloride or soidum iron pyrophasphate for 40 daysafterweaning (21 days) gave results for relative iron retentionandhemoglobin regeneration similar to those obtained with depletedrats fed the same supplements for 28 days.
