The present invention discloses a water flea feed formula for laying ducks at 0-3 week old. The feed formula comprises corn, lemna minor powder, water fleas, wheat middling, wheat bran, calcium hydrogen phosphate, stone powder and edible salt. The feed formula comprises the following components in percentages: 54.3% of corn, 5% of lemna minor powder, 20.15% of water fleas, 3% of wheat middling, 0.68% of calcium hydrogen phosphate, 15% of wheat bran, 1.52% of stone powder and 0.35% of edible salt. The calcium hydrogen phosphate added in the above components can effectively promote absorption ofnutrients by ducklings, nutrients of the added low-cost animal protein feed water fleas are far more than that in the fishmeal, the water fleas are used as the protein feed, a main deficiency is thatcontent of methionine and cystine is relatively low, and when the feed formula is used to feed monogastric animals, supplement is better given. Therefore, the formulated product is nutritionally balanced.
