Trace minerals exist in cells and tissues of the animal body in a variety of functional and chemical combinations and in characteristic concentrations that vary with the mineral and tissue (McDowell, 1992; Underwood and Suttle, 1999). The concentrations of trace minerals must usually be maintained within quite narrow limits if the functional and structural integrity of the tissue is to be maintained and the growth, health and productivity of the animal are to remain unimpaired (McDowell, 1992; Underwood and Suttle, 1999).
