Representative Sampling of Animal Feed and Mixtures in the Danish Agricultural Sector

Sampling of grain, animal feeds (solid and liquid) including important mineral mixtures in the Danish agricultural sector is subject to an ongoing investigation with the objective of improving existing (suboptimal) sampling procedures. Results from the first six months are presented here; the project will continue for two more years and will include international collaborators (Australia and Canada). The Danish authorities have instituted a system of control analysis, which contains a set of mandated sampling and analysis methods. From a preliminary survey it was concluded that in fact all of the existing sampling procedures are not optimised in the light of Pierre GyÆs Theory of Sampling (TOS).
