Chicken feed additive for producing selenium-rich eggs and application of chicken feed additive

Abstract

The invention provides a chicken feed additive for producing selenium-rich eggs. The chicken feed additive is characterized by being formed by mixing the following components in percentage by mass: 0.1-0.2 percent of methionine, 0.02-0.05 percent of vitamin E, 0.1-0.3 percent of vitamin C, 1-2 percent of choline, 1-2 percent of menotropins, 1-2 percent of betaine, 50-55 percent of Chinese herbal medicines, 0.2-0.5 percent of bacillus subtilis, 30-35 percent of tea dregs, 0.2-0.5 percent of selenium-enriched yeast and 5-10 percent of zeolite powder, wherein the Chinese herbal medicines are prepared by mixing pericarpium citri reticulatae, hawthorns and chilli according to a mass ratio of 1 to 1 to 1. According to the chicken feed additive for producing the selenium-rich eggs, the quality of the eggs can be obviously improved, and the production cost is lowered; meanwhile, the oxidization resistance, the stress resistance and the organ immunity of laying hens are improved; the chicken feed with the chicken feed additive can safely, stably and reliably produce the selenium-rich eggs.

Description

technical field [0001] The invention belongs to the field of feed, and specifically refers to a chicken feed additive for producing selenium-enriched eggs and an application thereof. Background technique [0002] Selenium is an important component of some antioxidant enzymes (glutathione peroxidase) and selenium-P protein in animals and humans, and plays a role in balancing the redox atmosphere in the body. Studies have proved that selenium has the effect of improving animal immunity, and the research on the effect of selenium on immunity and cancer prevention is a hot issue in this field in the world. Selenium has been regarded as an essential trace element for human body. At present, the adult intake recommended by the Chinese Nutrition Society is 50-250 micrograms per day, while the selenium intake in two-thirds of my country is lower than the minimum recommended value. China is a region rich in selenium resources, but also has a large area of ​​selenium deficiency, whi...

Problems solved by technology

At present, sodium selenite is often added to chicken feed to produce selenium-enriched eggs, but if this feed is used to feed chickens, the selenium content in eggs is unstable

High selenium content in feed will lead to selenium poisoning of laying hens, and the egg production rate will decrease

If the selenium content in feed is low, the selenium content in eggs cannot be effectively increased
