Method for preparing nonreactive selenium-rich laying hen feed additive

Abstract

The invention relates to a method for preparing a nonreactive selenium-rich laying hen feed additive. Eggs are necessary food in daily life of people, and are rich in nutrition. In recent years, professional raising farmers abuse antibiotics and hormones to acquire profits and prevent chicken diseases, and consequently, egg drug residues are serious, and physical and psychological health of people is affected. According to the method, lycopene, natural lutein, chitosan oligosaccharide, selenium yeast, diaminocaproic acid, diaminocaproic acid, lactic acid bacteria, bacillus subtilis, vitamin E, brewer's yeast, phytase, vitamin C, malic acid, lactic acid and water are organically mixed and fermented to be prepared into the nonreactive selenium-rich laying hen feed additive. Then, the nonreactive selenium-rich laying hen feed additive is combined with feed, intestinal probiotics of laying hens can be protected, absorption of nutrient substances can be promoted, the growing and reproducing function of the laying hens can also be adjusted, ovary development can be promoted, egg laying quality can be improved, the laying rate can be increased, and selenium-rich eggs free of antibiotic drug residues are produced.

Description

technical field [0001] The invention belongs to the technical field of poultry breeding, and specifically relates to a preparation method of an antibiotic-free laying hen feed additive using natural organisms, animal and plant extracts, trace elements and microbial bacteria as basic raw materials. Background technique [0002] Eggs are one of the most common consumer goods in people's daily life. With the continuous improvement of people's living standards, consumption is no longer limited to the demand for quantity, but more and more attention is paid to the quality of eggs, especially the drug residues in eggs. However, because a considerable part of laying hens in our country is currently limited by various conditions such as technology, site, and insufficient investment, in order to reduce the occurrence of chicken diseases, a considerable number of laying hen farmers have excessively added antibiotics and chemically synthesized drug additives during the production proces...

Problems solved by technology

However, because a considerable part of laying hens in our country is currently limited by various conditions such as technology, site, and insufficient investment, in order to reduce the occurrence of chicken diseases, a considerable number of laying hen farmers have excessively added antibiotics and chemically synthesized drug additives during the production process. This will bring many adverse effects, such as drug residues, environmental pollution, chronic poultry poisoning, carcinogenicity to humans, etc., especially easy to cause drug resistance of pathogenic microorganisms, which is a major weakness of western medicine feed additives such as antibiotics

Some antibiotics can enter eggs through the metabolism of chickens, resulting in antibiotic residues in eggs. If humans eat "resistant eggs" for a long time, antibiotics will slowly accumulate in the body, which will not only affect the function of the immune system, but also reduce the body's immunity. At the same time, the drug resistance of the human body is also continuously enhanced, which may lead to some diseases that cannot be cured
