Optimizing protein levels in diets containing distillers’ grains



Optimizing protein formulation in the diet of growing beef cattle is one of the most effective and practical methods of improving feed conversion efficiency and growth performance. Many protein feeds are commercially available for cattle, including soybean meal, canola meal and distillers’ grains (DG). Canola meal is a common protein feed in western Canada and its production is expected to increase. However, canola meal protein is degraded more readily in the rumen. DG, a by-product from the process of grain-based ethanol production, is used in beef cattle diets depending on its availability and price relative to the cost of cereal grains. Chemical composition and feeding value of DG vary with grain source and milling process.

A recently-completed research project, funded by the National Check-off and Canada’s Beef Science Cluster, worked to determine: Continue reading
