INTER-LABORATORY INVESTIGATIONS ON EVALUATION OF INDUSTRIAL FODDER MIXTURES HOMOGENEITY

The paper presents results from the comparative studies upon methods of industrial fodder mixtures homogeneity evaluation. Competence of participating laboratories to make a legal control within that issue was confirmed. Achieved results on the mixing level (variability coefficient) of fodder mixtures for turkeys and swine were lower than 10% - limit value. Reproducibility limits of results achieved by two laboratories determining chlorides and calcium within legal control were set for 5% (chlorides) and 3% (calcium). Acceptance of expanded uncertainty at the same level as uncertainty of analytical methods was recommended.
