![]() ![]() However, the relatively high fiber content of wheat DDGS reduces nutrient digestibility and impairs the growth rate of broilers fed diets containing high levels of wheat DDGS. įrom an economic standpoint, wheat DDGS are an attractive feedstuff for use in poultry rations. After complete fermentation, the ethanol is removed by distillation and the remaining fermentation residues are dried and used for livestock feed. amylases, proteases and xylanase) are added to the mixture to convert starch to sugar and the sugar is fermented by the addition of yeast. ![]() To produce ethanol, grain is milled, mixed with water and cooked. Most importantly, ethanol-blended fuels have the potential to reduce motor vehicle greenhouse gas emissions by as much as 30%. Ethanol-blended fuels offer several advantages over regular gasoline including protection from gas line freezing and higher octane ratings. There is increasing interest in producing ethanol from cereal grains for use in motor fuel. ![]() These changes in chemical composition supported increased weight gain of broilers fed wheat DDGS. Post-production fractionation of wheat DDGS improves their nutritional value by lowering their fiber content and increasing their content of crude protein and energy. Feed intake, feed conversion and mortality were unaffected by level of fractionated wheat DDGS in the diet ( P > 0.05). Weight gain increased linearly ( P = 0.05) as the level of fractionated wheat DDGS in the diet increased. The ATTD of dry matter and gross energy were linearly increased ( P 0.05). The experimental diets contained 5, 10, 15 or 20% fractionated wheat DDGS added at the expense of regular wheat DDGS. The control diet was based on wheat and soybean meal and contained 20% regular wheat DDGS. MethodsĪ total of 150, day-old, male broiler chicks (Ross-308 line Lilydale Hatchery, Wynyard, Saskatchewan) weighing an average of 49.6 ± 0.8 g were assigned to one of five dietary treatments in a completely randomized design. This experiment was conducted to determine the effects of fractionation of wheat DDGS on apparent total tract digestibility (ATTD) and performance when fed to broiler chicks (0–21 d). Post-production fractionation of wheat distillers grains with solubles (DDGS) increases their crude protein content and reduces their fiber content. ![]()
