Technical Field

The invention relates to the technical field of feeds, in particular to a method for preparing a selenium-rich ferment feed.

Background

Selenium is a multifunctional life nutrient, can remove free radicals, resist oxidation, strongly inhibit the generation of lipid peroxide, enhance the immune function (20 times to 30 times), protect biological cell membranes, enhance the prostate regulation function, prevent blood clots and remove cholesterol, has the same function as insulin, can obviously promote the sugar uptake capacity of cells, prevent blood circulation and skin aging, reduce the carcinogenicity of carcinogenic substances, eliminate cancer cells mutated in vivo, prevent division and growth of cancer cells and the like. With the development of science, selenium is increasingly recognized by human beings and is called 'vital element' and 'life fifth element'.

With the continuous emergence of the problem of food safety, the quality of meat such as poultry, livestock, fish and shrimp is widely concerned. Selenium can antagonize heavy metals, reduce the use of antibiotics by improving the immunity of animal organisms and improve meat quality to a certain extent, so the development of selenium-rich meat becomes one of the focuses of nutrition researchers.

At present, the development of domestic selenium-rich poultry meat is less, and the selenium-rich poultry meat is mainly concentrated in areas with high selenium content in soil. The main means for developing common selenium-rich poultry, livestock and fishes and shrimps is realized by feeding grain crops in selenium-rich areas, while the development of the selenium-rich poultry, livestock and fishes and shrimps in selenium-poor areas by using the method is almost impossible, and the main problems of the means are that the selenium content in meat is unstable and the standardized cultivation cannot be realized; in addition, selenium in grain crops is not easy to be directly absorbed by poultry, so that even if a large amount of selenium-containing grains are fed to poultry, livestock, fish and shrimp, the selenium content of meat or other edible parts of the poultry, livestock, fish and shrimp cannot be effectively increased.

Selenium-rich crop products (such as selenium-rich rice, selenium-rich millet and the like) are developed more in China, and selenium-rich products are also more on the market, but development of selenium-rich meat products is less.
