Selenium-enriched core powder production method and selenium-enriched core powder produced by the same

Abstract

A selenium-enriched core powder production method comprises the following steps: mixing corn, soybean meal, and wheat bran according to a weight ratio of 10:7:3, crushing to obtain a crushed raw material; adding water into the crushed raw material, stirring, wherein the adding amount of water is 60%-70% of the total weight of the crushed raw material; adding an inorganic selenium salt additive into the crushed raw material, stirring to obtain a fermentation raw material; spreading the fermentation raw material in a fermentation bed, performing fermentation with fermentation time of 48-72 hours at a fermentation temperature of 20-32 DEG C so as to obtain a selenium-enriched raw material containing organic selenium; performing sun drying of the selenium-enriched raw material, crushing again to obtain the selenium-enriched core powder. The invention also provides the selenium-enriched core powder produced by the selenium-enriched core powder production method.

Description

Technical field: [0001] The invention relates to the technical field of organic selenium production, in particular to a production method of selenium-enriched core powder and selenium-enriched core powder produced by the method. Background technique: [0002] In animals, selenium is an essential component of glutathione peroxidase and 5-deiodinase, and also a component of many proteins, which plays an important role in the anti-oxidation, anti-stress, and improvement of immunity in animals. It plays an important role, and about two-thirds of my country's areas are selenium-deficient areas, so selenium supplementation is of great significance in animal production in my country. [0003] At present, in animal feed and feed additives, selenium supplementation is divided into inorganic selenium and organic selenium. Inorganic selenium is generally selenate, but selenate is highly toxic, and improper use will cause serious adverse consequences. Organic selenium Selenium has the a...

Problems solved by technology

[0003] At present, in animal feed and feed additives, selenium supplementation is divided into inorganic selenium and organic selenium. Inorganic selenium is generally selenate, but selenate is highly toxic, and improper use will cause serious adverse consequences. Organic selenium Selenium has the advantages of high absorption rate, strong biological activity, low toxicity and less environmental pollution. However, the conversion of inorganic selenium to organic selenium is mainly completed by animal or plant organisms. The conversion rate is low, the cost is high and the production volume is small.
