The invention provides a soybean lecithin oil formula feed. The formula feed comprises the following raw materials in parts by weight: 55-65 parts of white fish meal, 5-15 parts of soybean meal, 15-25 parts of alpha-starch, 3-7 parts of fish oil, 0-1 part of a vitamin premix, 0-1 part of a mineral matter premix, 0.01-0.1 parts of arachidic acid, 0.01-0.1 parts of (carboxymethyl)dimethyl-3-[(1-oxododecyl)amino]propylammonium hydroxide, 1-2 parts of calcium dihydrogen phosphate, 2-4 parts of cellulose, 35-50 parts of crude protein, 5-15 parts of crude fat, and 5-15 parts of crude ash, and 1-4 parts of soybean lecithin oil. The soybean lecithin oil is added into the feed in order to improve growth and feed coefficient of cultivated fishes and the like at a certain degree, fat contents of intestines and livers are substantially reduced, and adverse influences are not generated. The soybean lecithin oil formula feed has the efficacies for regulating nutrition, supplementing nutrition and improving utilization rate of feed, as well as reducing dust flying and automatic grading during production of feed in the aspects of processing properties of the feed, and improving physical quality and yield of granulation. The feed can be used as a bonding auxiliary agent in aquatic product feed, in order to improve drifting and settlement of the aquatic product feed in water, and reduce feed waste and water quality pollution.
