Feed for producing selenium-enriched and chromium-enriched eggs and selenium-enriched and chromium-enriched chicken

The invention discloses feed for producing selenium-enriched and chromium-enriched eggs and the selenium-enriched and chromium-enriched chicken. The feed consists of 90 to 95 parts of base material and 5 to 10 parts of health-care material in parts by weight; the base material consists of the following components in parts by weight: 20 to 45 parts of corn flour, 10 to 35 parts of broken rice, 10 to 15 parts of rice bran, 8 to 25 parts of yeast cell wall, 1 to 2 parts of tea powder, 2 to 3 parts of nucleic acid yeast autolytic powder, 1 to 2 parts of selenium-enriched yeast and 1 to 2 parts of chromium-enriched yeast and 0.5 to 1 parts of feed-grade multi-vitamins; the health-care material is traditional Chinese medicine extract powder; the base material and the health-care material are evenly mixed in proportion; a proper amount of water is added for wetting; by adopting an extruding granulation manner, the raw material is extruded into particles of which the diameter is 0.5 to 1mm; then, the particles are baked at 85 to 90 DEG C for 2 to 3h, and are flavored to obtain the feed for producing the selenium-enriched and chromium-enriched eggs and selenium-enriched and chromium-enriched chicken after flavoring is finished. The feed disclosed by the invention has the beneficial effects that combination is reasonable, nutrition is balanced, processing cost is low, and palatability and feeding attraction performance are good; the immunity of chicken can be obviously improved; the use ratio of the chicken is high; metabolic waste is less; after being fed with the feed disclosed by the invention, the chickens grow faster and are high in laid egg quality.
