Functions
Iron has an important role as a constituent of haemoglobin and
myoglobin (red pigment responsible for the absorption and transport
of oxygen); iron is essential in metabolism as a component of
a group of enzymes important in cell respiration. Deficiency
leads to anaemia.
Main sources of iron
Iron sulphate is by far the main iron source in premix and feed-mixtures.
Quality parameters
Free flowing
A few important advantages of this free-flowing sulphate are
the avoidance of caking, the ability to make homogeneous mixtures
as well as its excellent stability.
