Effect of Feeding a By-product Combination at Two Levels or By-product Alone in Feedlot Diets

A finishing cattle study was conducted to evaluate feeding a by-product combination at two inclusion levels, compared with these by-products fed alone, or a corn-based diet without by-products. Treatments consisted of 0% by-products, 30% WCGF (wet corn gluten feed), 15% WCGF with 15% WDGS (wet distillers grains with solubles), 30% WDGS, and 30% WCGF with 30% WDGS (DM basis). Final BW, ADG, and F:G were improved for cattle fed by-products, including the 60% Blend. No associative effects resulted from feeding WCGF and WDGS in a blend compared to these by-products fed alone. Feed conversion was similar for feeding a by-product blend at 30 and 60% of dietary DM. A by-product blend at 30% did not have any additive effects, while a blend at 60% had comparable F:G to a blend at 30% with higher gains than the corn diet
