The invention discloses biological fermented meat duck feed. The biological fermented meat duck feed comprises, by weight, 20-30 parts of corn, 15-20 parts of black bean flour, 7-10 parts of corn stalk powder, 5-10 parts of soybean concentrated proteins, 10-15 parts of weed seeds, 6-9 parts of vegetable waste, 6-8 parts of palm kernel meal, 8-10 parts of ziziphus jujube leaves, 5-10 parts of conchmeal, 5-10 parts of bean pulp, 2-5 parts of orange peel, 3-7 parts of shrimp head meal, 1-2 parts of biological bacteria, 1-2 parts of complex enzyme preparations, 1-4 parts of salt, 0.8-2 parts of mushroom, 1-3 parts of bean worms, 1-3 parts of broken stone, 0.5-0.8 part of multi-vitamins, 0.1-0.4 part of lysine, 0.05-0.15 part of methionine and 1-3 parts of calcium hydrophosphate. The biological fermented meat duck feed has the advantages that the biological bacteria and the complex enzyme preparations are matched with one another, accordingly, the biological fermented meat duck feed can besynergistically fermented, and the average daily weight gain and the feed intake of meat ducks can be increased after non-fermented feed is replaced with the biological fermented meat duck feed.
