[Effect of various preparations of iron on the growth and haemoglobin levels of newborn piglets (author's transl)].

Four preparations of iron dextran, which differed markedly in price, were compared in an experimental study. 100 or 200 mg. of iron were injected intramuscularly on the first, second or third day of life of the piglets. Differences in weight or concentration of haemoglobin were not detectable during the first eight weeks of life, neither at a dosage of 100 mg. nor at a dosage of 200 mg. of iron.
