Trace elements in rye grass

Grass and clover for animal feed are routinely analysed to determine elements of nutritive quality (e.g. Ca, Mg, K, P, N, Mn etc.) and of potential risk (e.g. Cd, Hg). The results of determination of nutritive elements are used in the design of a well-balanced diet. The determination of the dangerous elements is necessary to avoid affecting the health of domestic animals which would lead to a lower production (economic loss) or even could cause damage to the consumer of animal products (milk, meat etc.). The rye grass material described in this chapter was produced for the quality control of determinations of important heavy elements, either of dangerous nature (e.g. Cd, Pb, Hg, Cu, Zn) or their role in animal nutrition (e.g. Se, Mo) [7,8].
