Abstract

The invention relates to a preparation method of a selenium yeast feed additive. The preparation method comprises the following steps: firstly preparing a fermentation substrate by taking alcohol industry yellow water, bran, rice bran, corn flour and other industrial and agricultural side products as raw materials, then performing yeast screening and acclimatization and culture to obtain selenium-rich yeast, inoculating to the prepared fermentation substrate and fermenting, and drying, grinding and packaging the fermented materials to obtain the selenium yeast feed additive. Compared with the chemically synthesized selenium yeast feed additive, the selenium yeast feed additive adopts the rice bran, bran, alcohol industry yellow water and other industrial and agricultural side products as culture raw materials and substrates, so that the resource utilization is increased, the waste and environment pollution can be decreased, and the production cost of the selenium yeast feed additive is lowered.

Description

technical field [0001] The invention relates to the field of biological feed additive processing, in particular to a method for preparing yeast selenium feed additive by using yeast. Background technique [0002] Selenium is one of the essential trace mineral elements for animals. Selenium deficiency can easily lead to typical symptoms such as muscular dystrophy, liver necrosis, exudative diathesis, and pancreatic fibrosis. In my country, there are regional differences in selenium deficiency. For non-selenium-deficient regions, the selenium contained in the feed raw materials can meet the needs of animals, and generally no additional addition is required. However, for animals in selenium-deficient areas or special stages, additional selenium is required. At present, as a selenium supplement, inorganic sodium selenite is still the main form of addition. The absorption rate of sodium selenite is relatively high, and generally there is no problem of utilization rate. However, ...
