Selenium-rich composite feed and production thereof

Abstract

The invention discloses a selenium-rich composite feed. The selenium-rich composite feed comprises the following raw materials: honeysuckle flowers, chrysanthemum flowers, rhizoma coptidis, liquoriceroots, pseudo-ginseng, selenium-rich distiller's yeast, selenium-rich yeast, wheat flour, silkworm chrysalis powder, wheat germ powder, bran, fish meal, rice bran, corn flour, soybean meal, trace elements and vitamins, and is prepared by secondary fermentation. According to the selenium-rich composite feed disclosed by the invention, the rice bran, bran powder, wheat flour, wheat germ powder and corn flour which are high in selenium content are adopted, so that livestock and poultry can fully digest and absorb selenium elements after eating the selenium-rich composite feed, and then the selenium elements can be converted into requirements of a human body after people eat the livestock and poultry; and unlike inorganic selenium salt with toxicity, the selenium-rich composite feed has no toxic or side effect on poultry eggs and human bodies.

Description

technical field [0001] The invention belongs to the field of feed preparation, and in particular relates to a selenium-enriched compound feed and a production method thereof. Background technique [0002] Livestock and poultry diets must be supplemented with a certain amount of selenium to exert their normal physiological functions. At present, it has been used to add inorganic sodium selenite (NaSeO2) to livestock and poultry diets. 3 ) to meet its needs. However, sodium selenite has certain toxicity, and the biological potency is also very low, and the residence time in the body is short, generally only 3-4 hours, and excessive supplementation is not conducive to food safety because of its toxic effect. [0003] Most of the currently reported selenium supplementation methods use biotransformation technology to produce various products containing trace element selenium through the transformation of animals and plants. The Chinese patent application with publication number...

According to the World Health Organization, the normal intake of selenium per person per day is 50-250 micrograms of selenium. There are many companies in the market that produce selenium nutrition products, especially agricultural selenium enrichment. The whole country is in full swing, but the general cost is high. As a result, the cost of agricultural products has been increased, and the sales of agricultural products have encountered bottlenecks

[0004] Existing feeds, such as chicken feeds, are deficient in various nutrients due to unreasonable formulas. Generally, they are fed with single feeds such as corn, grass powder, bean cake, and rice bran, which cannot meet the growth and nutritional needs of chickens at all. , hinders the normal growth and development of chickens, and is susceptible to various infectious diseases, resulting in a loss of benefits. At the same time, the nutritional value of chickens is also greatly reduced, and the quality deteriorates
