Technical method for producing antibiotic-free selenium-enriched laying hen feed by insects

The invention discloses a technical method for producing antibiotic-free selenium-enriched laying hen feed by insects. The technical method is characterized by comprising the following steps of: cleaning insects, including fly maggots, earthworms, cockroaches, silkworm larva, centipedes, dioscorea cirrhosa, Caulis Fici Tikouae and fructus gardeniae which are rich in selenium elements and have antibacterial and antivirus functions, and performing classified pretreatment according to the growth characteristics of each raw material; and then through technologies, including mixing, stirring, sterilizing, disinfecting, fermenting, drying and the like, mixing the obtained feed with daily compound feed for feeding chickens to be mixed and fed. The laying hen feed synthesized from the components, the antibacterial peptide, the high protein, the amino acid and the specific trace elements is used for feeding livestock, is comprehensive and rich in nutrients, and can obtain various beneficial nutrient components.
