Background
Selenium is one of 14 trace elements indispensable to human and animals. Is involved in human metabolism and is a component of glutathione peroxidase, which prevents the accumulation of perchlorase in cells, thereby protecting the cells from damage. Selenium deficiency can cause a range of diseases in humans and animals. The reasonable selenium supplement can enhance the physique of people, enhance the immunity of organisms and prevent and treat diseases, and a large amount of data show that the selenium can prevent and treat keshan disease and Kashin-Beck disease and has certain curative effect on hypertension and cardiovascular diseases. And has anticancer, immunity enhancing and antiaging effects. Has antagonistic effect on heavy metal poisoning.
According to the research results of feeds and pasture grasses in China, the selenium-deficient areas account for more than 70% of the total area of the whole country from the three provinces of northeast China to the Yunobuan plateau and from the Tibet, the Qinghai and most coastal areas of the east, and because people eat selenium-deficient food, the daily selenium intake of a human body is lower than or close to the minimum daily required amount, so that the selenium deficiency of the human body is caused. According to the NRC of the United states, the recommended daily selenium intake of adults is 50-200 micrograms, and the average daily selenium intake of each person in China is only 40-70 micrograms calculated by experts in China. At present, the main means of selenium supplement in China is to directly take tin-soldered medicinal health care products and the like, but the method is not strong in universality because certain side effects exist more or less in the taking of medicines, eggs are taken as one of the most frequently-eaten nutritional foods in daily life of people, the selenium content of each egg is 4-12 ug, the selenium content required by a human body can be supplemented to a certain extent, the feeding of laying hens is further upgraded at present in order to improve the nutritional value of the eggs, the laying hens can produce selenium-enriched eggs with the selenium content of 30-50 ug, and the economic benefit of the breeding is improved.
