The invention relates to the technical field of feeds and particularly relates to a formula feed for improving the growth performance of meat ducks. The feed is prepared from the following raw materials in parts by weight: 25-30 parts of wheat bran, 12-15 parts of corn distiller grains, 65-75 parts of corns, 12-15 parts of cottonseed meal, 20-25 parts of rapeseed meal, 15-20 parts of barley straws, 12-15 parts of black wheat bran, 8-10 parts of unshelled rice bran, 4-5 parts of trester,3-4 parts of water hyacinth dry meal, 3-4 parts of stevia rebaudiana stems and leaves, 1-2 parts of gravel, 1-2 parts of whitebait meal, 1-2 parts of eel dry meal, 1-2 parts of cabbage caterpillar dry meal, 3-4 parts of foeniculum vulgare seedlings, 3-4 parts of fescues, 1-2 parts of red kojic meal, 4-5 parts of tender water caltrop stems and leaves, a suitable amount of table salt and 0.2-0.5 part of a phagostimulant. According to the meat duck formula feed provided by the invention, all the easily available raw materials are pure natural materials and are low in price, and thus the breeding cost is reduced effectively; meanwhile, the growth and development of meat ducks can be accelerated, the breeding period of the meat ducks is shortened, the growth performance of the meat ducks is improved effectively and the breeding benefits are improved.
