The invention provides an ecological soft-shelled turtle compound feed. The feed comprises the following components in part by weight: 50 to 56 parts of fish meal, 20 to 24 parts of alpha-starch, 3 to 5 parts of fermented soybean meal, 1 to 3 parts of puffed soybean, 1 to 2 parts of liquid fish oil, 1 to 3 parts of beer yeast powder, 1 to 2 parts of methionine, 1 to 2 parts of lysine, 1 to 2 parts of skimmed milk powder, 1 to 2 parts of yolk powder, 0.5 part of composite mineral substance, 0.4 part of composite vitamin, 1.5 parts of monocalcium phosphate, 0.1 part of phytase, 0.2 part of Chinese medicinal herb additive, 1 part of kelp powder, 1 part of lecithin, 0.1 part of beta-glucan, and 0.1 part of Baoganning. The formula of the compound feed is scientific and reasonable, the disease resistance of ecological soft-shelled turtles is improved, discharge of pollutants such as nitrogen, phosphorus and the like is reduced, the requirement of ecological breeding is met, the absorption and utilization rate of the feed is improved, the nutrient requirement of the ecological soft-shelled turtles is met, and the breeding cost is reduced; and the preparation method is scientific and reasonable, and has remarkable economic benefits and environmental benefits.
