A draft standard method is presented for the determination of Ca, Cu, Fe, Mg, Mn, K, Na, and Zn in animal feeding stuffs. The method specifies dry ashing of samples and detection by atomic absorption spectrometry (AAS). The applicability of the method for various concentrations of the elements was tested in a series of 3 collaborative studies. The feeding stuffs investigated include pulp pellets, grass, mixed feed, fish meal, milk powder, maize, sheep feed, lupin, milocorn, feather meal, and blood meal. Relative standard deviations, repeatability, and reproducibility are given. The reproducibility of the method was acceptable for following approximate minimum quantities: Na and K, 1000 mg/kg; Zn, Mn, and Cu, 10 Mg/kg; Fe, 10-200 mg/kg, depending on the product.
