The invention discloses selenium-rich feed for laying hens. The selenium-rich feed comprises the following raw materials: 20-30 parts of a sawdust adsorbent, 10-20 parts of an activated carbon slow-release agent, 1-2 parts of 99% sodium selenite, 2-3 parts of 98% zinc sulfate, 70-80 parts of corn, 20-25 parts of wheat bran, 10-15 parts of bean meal, 10-15 parts of wheat, 10-15 parts of oat, 10-15parts of sesame cakes, 5-10 parts of fishmeal, 26-30 parts of stone powder, 1-3 parts of animal oil, 2-8 parts of calcium hydrogen phosphate, 13-15 parts of corn distiller's grains, 1-2 parts of choline chloride, 0.5-1 part of lysine, 0.4-0.8 part of methionine, 1-2 parts of threonine, 0.2-0.5 part of sodium chloride, 0.1-0.2 part of sodium humate, 0.1-0.2 part of M-P(T), 0.1-0.2 part of BV22A, 0.1-0.2 part of phytase and 0.3-0.5 part of complex enzymes. By research and application of the selenium-rich feed prepared using scientific and modern technologies, diseases caused by lack of seleniumtrace elements in poultry are treated, the survival rate is improved and healthy selenium-rich poultry meat is produced.
