Production method of antibiotic-free selenium-enriched eggs

Abstract

The invention discloses a production method of antibiotic-free selenium-enriched eggs. No antibiotic is used in the whole raising process of chickens, the chickens are raised in a cage-free mode, organic selenium of the different standards is added in chicken feed, the selenium content of the eggs is increased through the bio-concentration action, hens are raised in a mountain in a cage-free mode, the laying hens are fed on Chinese herbs and selenium-enriched forage in the mountain, and therefore the immunity of the laying hens is enhanced, wherein a water solution obtained after protein selenium or yeast selenium or selenium methionine is diluted or feed is adopted as the organic selenium. According to the production method, the organic selenium which is little in toxicity and rapid to absorb is used, usage is easy and convenient, large-area popularization is convenient to achieve, the produced eggs do not contain antibiotics, pure, free of pollution and rich in the organic selenium needed by a human body, and therefore the eggs have the very good health care effect and can prevent diseases such as cardiomyopathy and dysplasia.

Description

technical field [0001] The invention belongs to the technical field of breeding, and in particular relates to a method for producing anti-selenium-enriched eggs. Background technique [0002] my country is a selenium-poor country, and 72% of the regions are in selenium-deficient areas. The daily selenium intake recommended by the World Health Organization is 400 micrograms, and the daily selenium intake recommended by the Chinese Nutrition Society is 50-250 micrograms. Chinese people can only take in 17-30 micrograms of selenium from their diet every day. Selenium, as one of the 15 essential nutrients for the human body, is an excellent anti-peroxidation substance and has a good effect on malnutrition caused by lack of protein. Insufficient selenium intake in the human body, mild and moderate effects or not obvious, but severe deficiency can easily lead to cardiovascular diseases, diabetes, hypertension and other diseases. [0003] Eggs are rich in nutrients and contain a lot...

Problems solved by technology

[0003] Eggs are rich in nutrients and contain a lot of protein and other nutrients, but most eggs have very low selenium content. At present, 6-32mg / kg sodium selenite is mixed in the feed to produce selenium-enriched poultry in the market. Eggs and meat, and sodium selenite is inorganic selenium, poultry tolerance is low, it is easy to cause poisoning of hens, resulting in decreased egg production, and even death of hens, and the long-term use of antibiotics in feed threatens human health
