Plasma iron in domestic fowl

Abstract

The plasma iron and the total iron binding capacity of the serum have been de­ termined on a series of 273 specimen comprising 5 species. The laying period causes a notable increase in plasma iron without there being any perceptible modification in the total iron binding capacity. It is suggested that in fowl would must contein an auxiliary mechanism to transferrin in serum iron transport. Its existence would explain diverse peculiarities observed in the transportation of serum iron in fowls, in compa­rison with the situation existing in mammals.
