"The Retsch Ultra centrifugal mill is the one "grinder" that gave us the particle size and hence the best analytical result (e.g. oil content) in a variety of oilseed sample types. Over 30 years in the laboratory, allows me to call the Retsch mills/ grinders as the "gold standard" when it comes to sample preparation." Douglas DeClercq. DRD

Feed particle size is an often-overlooked aspect of poultry production. Producers should not assume that feed is of a uniform size and homogeneously mixed, or that the feed mill is providing the ideal mix of particles in a ration. Feed particles range in size from very fine to coarse, and different grinding methods will result in
