The present invention relates to a selenium-enriched and chromium-enriched spirulina platensis enzymolyzed residue compound feed and a preparation method thereof. The selenium-enriched and chromium-enriched spirulina platensis enzymolyzed residue compound feed comprises the following components: 20-45 parts of corn flour, 10-35 parts of broken rice, 10-15 parts of rice bran, 20-30 parts of spirulina platensis enzymolyzed residues, 20-30 parts of lotus leaf powder, 20-30 parts of fly maggot powder, 10-15 parts of a selenium-enriched yeast extract, 2-6 parts of radix scutellariae flavonoids and6-10 parts of a chromium-enriched yeast extract. An extraction method of the radix scutellariae flavonoids is as follows: S1, raw material crushing is conducted: a radix scutellariae raw material is dried to a water content of less than 8%, the dried radix scutellariae is crushed and the crushed radix scutellariae is sieved by a 60-80 mesh sieve; S2, two aqueous-phase extract preparing is conducted: a two aqueous-phase ex
