The present invention relates to the technical field of feeds and particularly to a selenium-enriched feed formula for egg-producing shelduck. The selenium-enriched feed formula comprises corn, wheatmiddling, wheat bran, rice bran, soybean meal, detoxified cottonseed protein, rapeseed meal, imported fish meal, stone meal, calcium bicarbonate powder, edible salt, L-lysine, methionine, choline chloride, complex enzymes, phytase, sodium sulfate, flavoring substances, ethoxyquinoline, a microbial preparation, complex multi-vitamins, Chinese yams, radix astragali, haws, licorice, dried orange peels, red dates, Chinese wolfberry fruits, radix isatidis, malt, garlic, common andrographis herb, ferrous sulfate monohydrate, copper sulfate pentahydrate, zinc sulfate monohydrate, manganese sulfate monohydrate, calcium iodate, cobalt chloride hexahydrate, methionine selenium, zeolite powder and bentonite. Beneficial effects are as follows: the selenium-enriched feed formula increases content of organic selenium in duck eggs, produces the reinforced selenium-enriched nutrient eggs integrating health care and nutrition, and achieves an effect of supplementing selenium for human body. Compared with selenium-enriched duck meat, the selenium-enriched shelduck eggs have advantages of simple operation, convenient popularization and promotion, etc.
