Abstract

The invention is applicable to the technical field of feeds, and provides an organic selenium feed additive as well as a preparation method and application thereof. The organic selenium feed additivecomprises selenium-enriched stevia rebaudiana, selenium-enriched barbarea orthoceras and selenium-enriched wormwood leaves, wherein the mass ratio of the selenium-enriched stevia rebaudiana to the selenium-enriched barbarea orthoceras to the selenium-enriched wormwood leaves is (27-45):(50-70):(3-5). Organic selenium is used as a selenium supplementing raw material, so that the safety is high; theorganic selenium feed additive can increase the selenium content of animal food, has a good selenium supplementing effect, and can meet demands of human bodies; and harmful bacteria and parasites inintestinal tracts and blood of animals can be expelled, the occurrence probability of animal diseases is reduced, the physique of the animals is enhanced, and the yield of the animals is increased.

Description

technical field [0001] The invention belongs to the technical field of feed, in particular to an organic selenium feed additive and its preparation method and application. Background technique [0002] Selenium is an essential trace element for humans and animals. It plays an important role in human life activities. It is a component of various enzymes. People can improve the body's immune function, disease resistance, and delay aging by supplementing selenium. [0003] Since animal foods have a good accumulation effect on selenium, selenium nutrition is strengthened in animal feeding, and the human body's demand for selenium can be increased by eating animal foods. [0004] However, some selenium supplementation feeds currently use highly toxic inorganic selenium. Excessive dosage can easily cause animal poisoning and death, and the selenium supplementation effect is also poor. The selenium content in animal foods is low, which cannot meet the human demand. Contents of th...
