Methods for the analysis of premium livestock grains

The literature contains a wide range of reported values for the content of most chemical constituents of feed grains and meals. It is not possible to assess accurately how much of this variation is due to genotypic and enviro nmental factors and how much to differences in methodologies between labora tories. We have reviewed the literature for the preparation and analysis of feed grains (cereals, legumes, and oilseeds) and made recommendations for procedures considered to give the most accurate and reliable results. Recom mendations are also made for a quality assurance scheme, an inter-laborator y evaluation program, and the use of reference materials. Australia-wide ad option of these practices should ensure that any future variations observed can be ascribed to genotype and/or environment. This review is part of a n ational premium feed grains quality project which, in turn, is part of a pr ogram to provide more accurate and reliable information about the true valu e of our feed grains to the domestic and international feeds industries.
