Breeding method for selenium-enriched black-bone chicken

Abstract

The invention relates to a breeding method for selenium-enriched black-bone chicken.Chinese little green planting and black-bone chicken breeding are mixed, the black-bone chicken are bred in the middle growth stage of Chinese little greens and just need to be fed with selenium-enriched feed one time per day, and the black-bone chicken can eat the Chinese little greens for daily need in the rest periods of time; a fermented selenite and wheat juice mixed solution is rich in selenium and is sprayed to leaves of the Chinese little greens after being mixed; after the Chinese little greens absorb the solution, the planted Chinese little greens also contain abundant selenium so that the black-bone chicken can eat the Chinese little greens; due to the fact that the planting period of the Chinese little greens is short, harvesting can be performed 40-50 d after seedlings emerge, the harvested Chinese little greens can also be used as selenium-enriched raw materials so that the black-bone chicken can eat the Chinese little greens, a certain number of feed resources are saved, the selenium-enriched feed made form selenium-enriched yeast, vitamin c, Chinese milk vetch, green bristlegrass seeds, wheat bran and soybean oil, meanwhile, the disease resistance of the black-bone chicken can be improved, the meat of the black-bone chicken is improved, and the black-bone chicken can be sold after the Chinese little greens are planted three times.

Description

technical field [0001] The invention relates to the technical field of poultry breeding, in particular to a method for breeding selenium-enriched black-bone chickens. Background technique [0002] Selenium is an essential trace element for the human body. It participates in the synthesis of various selenium-containing enzymes and selenoproteins in the human body. Selenium-enriched food selenium can improve human immunity, promote the proliferation of lymphocytes and the synthesis of antibodies and immunoglobulins. Selenium is beneficial to colon cancer, Skin cancer, liver cancer, breast cancer and other cancers have obvious inhibitory and protective effects, and its intermediate metabolite methyl enol in the body has strong anticancer activity. Selenium is not evenly distributed on the earth's surface. Most of the soil is deficient in selenium, resulting in selenium deficiency in agricultural products. Cause selenium deficiency in the human body; cause cardiovascular and ce...
