Use of Wheat Distiller Grains in Ruminant Diets
Wheat grain is commonly used to produce ethanol in Canada and Europe. During ethanol production processing, starch in the grain is fermented almost completely, and the remaining protein, fibre, fat, minerals and vitamins increase approximately 3-fold in concentration compared to the original grain. By-product derived from the ethanol production is named distiller grain and primarily used in feeding livestock animals. Wheat-based distiller grain is high in energy, protein and fibre. These properties give wheat distiller grain unique feeding opportunities for various classes of livestock as both energy and protein supplements as well as fibre source. This chapter summarizes some recent research findings published in peer reviewed and extension chapter on the use of wheat distiller grain in ruminant diets. Substantial variation in chemical composition exists among the distiller grain samples, which are mainly influenced by inherent original grain and technology used in ethanol plant. Wheat distiller grain can be used to partly replace grain or forage portion at moderate levels to meet energy and fibre requirements of cattle. A manure management plan needs to be developed that considers the fact that inclusion of wheat distiller grain in the diet will dramatically increase the nitrogen and phosphorus content in manure.
