Method for greatly improving selenium content in eggs

Abstract

The invention discloses a method for greatly improving the selenium content in eggs. The method has the advantages that the selenium content in the produced eggs can be greatly improved; the nutrition requirements of a human body can be met; the free-ranging management is performed in a mountainous area or farmland; quartz sand is fed at a fixed point. The selenium content of the eggs laid by hens fed by using the method is more than 50 times higher than that of selenium-rich eggs produced by using a common culture method.

Description

technical field [0001] The invention belongs to the field of breeding, in particular to a method for greatly increasing the selenium content of eggs. Background technique [0002] Selenium is a chemical element with the chemical symbol Se, a non-metal. It can be used as a photosensitive material, a catalyst in the electrolytic manganese industry, an essential nutrient element for animals and a beneficial nutrient element for plants, etc. General selenium is combined with Schisandra chinensis to make liver-nourishing tablets, which has the function of protecting the liver. Its content in food depends on the selenium content of the soil in different regions. As long as the soil is rich in selenium, the food grown from it must have selenium. The results of the medical census show that the areas with high soil selenium content have significantly lower cancer incidence rates than those in areas with low selenium content. Studies have shown that an effective measure to prevent ...
