The invention discloses a method for preparing a biological feed from arrow root starch processing waste residue. The biological feed is prepared from the following raw materials in percentage by weight: 50 to 55 percent of arrow root starch processing waste residue, 20 to 30 percent of oil bran or wheat bran, 8 to 10 percent of corn flour, 8 to 15 percent of bean pulp, 0.1 to 0.2 percent of ferment bacterium, 0.2 percent of brown sugar, 2 to 3 percent of fish meal, 0.5 percent of urea, 1 to 1.5 percent of calcium superphosphate, 0.1 percent of common salt, copper sulfate, ferrous sulfate andzinc sulfate, wherein every ton of feed comprises 105g of copper sulfate, 105g of ferrous sulfate and 105g of zinc sulfate; and the feed is prepared by the following steps of: mixing the raw materials for 10 to 15 minutes; controlling water content to be 45 to 50 percent; uniformly mixing the raw materials, stacking the raw materials in a strip with width of 2 to 3m and height of 1.5 to 2.0m and performing anaerobic fermentation for 2 to 3 days; and drying the obtained product at the temperature of between 55 and 65 DEG C, or squeezing, granulating and drying at the temperature of between 55 and 65 DEG C. In the method, the arrow root starch processing waste residue serving as an organic waste is fully utilized, the high-efficiency and high-quality biological feed is produced, the production cost and the environmental cost are reduced, the environment is protected and the development of the ecological breeding is promoted.
