Laying hen feeding method for increasing selenium content of eggs

Abstract

The invention belongs to the technical field of selenium-enriched eggs and particularly relates to a laying hen feeding method for increasing the selenium content of eggs. The method comprises the following specific steps that from the age of 15 days of laying hens, a feeding material is fed twice a day, and a fermented feeding liquid is fed once. The feeding material is made of the following rawmaterials including fresh edible amaranth, fresh wheat leaves, fresh dandelion leaves, corn, tomato seed meal, activated medical stone powder, mesona blumes polysaccharide and curcumin. The fermentedfeed liquid is prepared according to the following steps that fresh sonchus oleraceus is washed, pulverized, subjected to constant temperature steaming and then taken out; carrots, purple grapes and water and added, beaten, fermented and then taken out, the mixture is magnetized and filtered, and the filtrate is taken to obtain the fermented feed liquid. Environmental-protection healthy productionof the laying hens and eggs is effectively promoted, the selenium content and folic acid content of the eggs are significantly increased, the nutritional and health-care value is increased, human health is promoted, the nutritional intake level of people's lives is increased, the egg weight can be effectively increased, and economic benefits are increased.

Description

technical field [0001] The invention belongs to the technical field of selenium-enriched eggs, in particular to a method for raising laying hens for increasing the selenium content of eggs. Background technique [0002] As an essential trace element in animals, selenium is the main component of glutathione peroxidase, which can protect the body from peroxide damage; selenium can be combined with vitamin B 2 , vitamin E, etc. have a synergistic effect to enhance the body's immunity and disease resistance; at the same time, selenium can antagonize and reduce the toxic effects of toxic elements; it also has the effect of preventing certain cancers; according to surveys, about 2 / 3 of my country's Selenium deficiency in the region, with the acceleration of the pace of modern life, the increase of people's life pressure, people's body has been in a "sub-key healthy" state for a long time, according to a survey conducted by the Chinese Nutrition Society on 13 provinces and cities in...

Problems solved by technology

[0003] Eggs are the main egg food that people eat in daily life. They have a long-standing eating habit, and eggs have a good accumulation effect on selenium. Selenium eggs can increase the human body's demand for selenium. Although there are already selenium-enriched eggs on the market, their selenium content is not ideal, and the production of rich selenium is produced by directly adding commonly used selenite and other inorganic selenium salts into the feed. Although selenium eggs can increase the selenium content in the feed, the toxicity of inorganic selenium salts is relatively large, which can easily lead to selenium poisoning in poultry eggs, and long-term consumption of eggs containing inorganic selenium salt feed will endanger people's health; Green eggs containing selenium are of great significance to meet the content of selenium in the human body
