Popis: Due to the increasing interest in the distillation of ethanol from grains a study was conducted to examine the potential usage of high levels of distillers residue in broiler diets. Two series of diets were formulated with up to 25% distillers dried grains plus solubles (DDGS). In one series the dietary energy was held constant at 3200 ME kcal/kg (fixed energy), while in the second series the energy declined as the level of DDGS increased but the energy:nutrient ratios were maintained constant (optimum energy). Diets were fed in mash form to chicks in battery brooders from day-old to 42 days of age. In the fixed energy series no significant differences in body weights or feed conversion efficiency were observed at 42 days of age that were related to the level of DDGS in the diet. In the optimum energy series there was a general decline in body weight gains and feed conversion efficiency at DDGS levels of 15% or more. However, the chicks on all levels of DDGS made similar utilization of the dietary energy, measured as calories per gram of gain. Therefore, levels of up to 25% DDGS could be used in broiler diets should price and supply dictate.
