Feed additive for selenium-rich beef

Abstract

The invention relates to a feed additive for producing selenium-rich beef. The feed additive is characterized by being prepared by mixing the following substances in parts by weight: 15-25 parts of 30% coated cysteamine hydrochloride, 8-12 parts of dihydropyridine, 130-150 parts of cardamine violifolia, 110-130 parts of flos lonicerae, 90-110 parts of stevia rebaudiana, 70-90 parts of rhizoma gynurae, 70-90 parts of fructus hordei germinatus, 7-9 parts of laifeng crossostephium leaf extract, 70-90 parts of fructus aurantii, 70-90 parts of fructus quisqualis, 30-50 parts of acetohydroxamic acid, 50-60 parts of commercially available selenium yeast containing 2,000mg / kg of selenium, 50-60 parts of commercially available bacillus subtilis and 50-70 parts of medical stone. The feed additive for producing the selenium-rich beef can prevent various diseases of cattle and provide safe and nutritional healthy food for citizens, and is optimal food and way for selenium supplement of the whole people, thereby having an important practical significance.

Description

technical field [0001] The invention relates to the preparation of a feed additive. The invention mainly relates to a feed additive for producing selenium-enriched beef. Background technique [0002] Selenium has long been recognized as an essential trace element for animals. The loss of animals due to selenium deficiency in feed is staggering on a global scale. In the United States, from the 1960s to the early 1980s, the annual loss of beef cattle, dairy cows and sheep due to animal selenium deficiency reached 545 million U.S. dollars, and the pig and poultry industry lost 0.82 billion U.S. dollars, which caused the United States Department of Agriculture to attach great importance to it. [0003] As early as 1966, New Zealand began to sell fortified selenium feed; Finland began to add 0.1mg / kg selenium to the feed in 1969; the United States injected 0.28mg sodium selenite at birth and 1.12mg at two weeks; and recommended feed Add 0.2mg / kg of selenium, 1mg / kg or less is ...
