The invention relates to a method for producing fly maggots for feeding chickens in a chicken farm. The method includes the following steps of (1) laying eggs, placing aseptic fly pupae in a fly house to incubate for 4 to 5 days to form imagoes, enabling the imagoes to reach to
sexual maturity after 2 to 5 days, starting
mating, and maintaining the temperature of the fly house in a range from 22 DEG C to 30 DEG C; (2) receiving the eggs, placing egg collecting substances prepared by wheat
bran and water through effective microorganisms (EM) in a white plastic box, forming egg clusters by laid eggs, and incubating the egg clusters for 16 hours at the temperature of 60 DEG C; (3) preparing
nutrient mediums by 80% of wheat
bran and water, EM and pig blood, placing the
nutrient mediums in a
maggot growing house, spreading the
nutrient mediums, placing the egg collecting substances and the eggs on the nutrient mediums uniformly, growing the eggs into larvae after 4 days, and separating out the larvae; and (4) maintaining the
room temperature in a range from 20 DEG C to 30 DEG C and the
humidity to be 60%, enabling the larvae to be transformed into pupae after 2 to 3 days, and incubating the pupae for 4 to 6 days to form flies. By means of the method, after the produced fly maggots are fed to the chickens, the laying rate of the chickens is increased, eggs laid by the chickens are physically beneficial and environment-friendly,
drug residues are absent, and the bred chickens are fresh and tender in meat quality and free of tranig.
