Selenium-rich egg production technology

[0017] Production technology of selenium-enriched eggs, including the following:

[0018] (1) Feeding conditions: keep the house temperature at 18°C, relative humidity at 45%, ensure that the light time of the house is 10 hours a day, the ventilation rate is 3 m³ / h·kg, and the stocking density is 5 birds / ㎡;

[0019] (2) Feeding conventional feed: before the age of 20 weeks, the chickens were fed conventional feed, and the preparation method of the conventional feed was as follows: corn, ryegrass, red bean grass, soybean meal, soybean oil, sodium chloride, hydrogen phosphate After calcium, medical stone powder, dandelion, Atractylodes Rhizoma, and 50% choline chloride are evenly mixed, a selenium-containing amino acid nutrient solution is added to the mixture, so that the selenium concentration of the entire mixture is 3ppm, and the conventional feed is obtained;

[0020] (3) Feeding selenium-containing egg-laying feed: starting from 20 weeks of age, the conventional feed fed
