The invention discloses DDGS-containing meat duck feed and a preparation method thereof. The compound feed comprises the following raw materials: corn, wheat, wheat middling, maize embryo cake, corn gluten meal, DDGS, bean pulp, peanut pulp, feather meal, fat, table salt, stone powder, calcium hydrophosphate, choline chloride, methionine, threonine, lysine, betaine, phytase, composite premix, emulsifier, vitamin premix and trace element premix. The preparation method comprises the following steps: weighing, crushing, mixing, granulating and crushing. When the technical scheme provided by the invention is adopted, the feed and the preparation method have the advantages that: the mixing ratio is scientific; the manufacturing is simple; and the DDGS high-quality raw material is used, the consumption of conventional protein raw materials such as corn and soybean pulp is reduced, the cost of the feed is reduced, the nutrient demands of meat ducts for growth are satisfied, adverse effect onthe growth property of the meat ducts is avoided, muscle rate is improved, abdominal fat rate is lowered, the quality of meat is improved obviously, and the crop rate is high.
