REFERENCE MATERIAL FOR THE ANALYSIS OF WHITE CLOVER

Objective



Clover and grass for animal feed are routinely analysed to determine elements of nutritive quality (e.g. Ca, Mg, K, P, N, S, Mn, Se, Mo) and of potential risks (e.g. Cd, As, Hg, Sb). The results of the determination of nutritive elements are used to improve the state of health and growth of domestic animals. Their diet must be well balanced and therefore basic feed often needs to be enriched with repect to trace and major elements. The determination of the dangerous elements is necessary to avoid health damage to the animals which would lead to a lower production (economic losses) or even could cause damage to the consumer of animal products, e.g. milk, meat, etc. Reference materials are helpful to avoid disputes on the quality of any of the raw materials for the preparation of animal feed. In addition, plant materials such as clover or grass are analysed as indicators of soil pollution with plant-available species. To control the quality of these determinations and consequently the quality of feed two CRMs have been already produced (Rye-grass, CRM 281 for the quality control of trace and toxic element analyses and Hay powder, CRM 129 for the monitoring of major elements). The certification of trace elements in clover was also found to be necessary for this purpose.

RESULTS

A white clover material was prepared and certified for its contents of As, Co, I, Mo and Se. Certification concluded (CRM 402), EUR Report in press
