Preparation method and use method of selenium-enriched beef cattle feed

Abstract

The invention relates to a preparation method and use method of a selenium-enriched beef cattle feed. The selenium-enriched beef cattle feed comprises forage grass, a concentrated feed and a selenium-enriched feed additive, wherein the forage grass comprises herbage, sugarcane ends, cornstalks and the like, the concentrated feed consists of corn, alfalfa, broccoli, soybean meal, peanut cakes, wheat bran, great burdock achene, sugarcanes, bone meal, baking soda and table salt, and the selenium-enriched feed additive is prepared through sufficient fermentation by using EM probiotics as a bacterium preparation and sodium selenite as a selenium source. When the selenium-enriched beef cattle feed is used for feeding beef cattle, the selenium-enriched feed additive is added to the concentrated feed according to a certain mass ratio, and continuous feeding is performed for definite time in a feeding manner of a normal concentrated feed before the beef cattle become full-grown and ready for slaughter so that selenium-enriched beef can be obtained.

Description

technical field [0001] The invention belongs to the technical field of breeding, and in particular relates to a method for preparing and using selenium-enriched beef cattle feed. Background technique [0002] Selenium is an essential trace element for humans and animals, and is hailed as "the magic element of life" by scientists. At present, there are many selenium supplement products on the market, which can be divided into two categories: inorganic selenium and organic selenium. Inorganic selenium includes sodium selenite, sodium selenate, selenium sulfide, etc. The absorption and utilization rate of inorganic selenium by the human body is low, the taste is poor, and it is easy to be poisoned, so it is generally not used as a selenium source; organic selenium includes selenium-enriched yeast, selenomethionine , selenocysteine, selenoprotein, etc. The human body has a high absorption and utilization rate of organic selenium, and has a good taste. It is recommended as a sel...

Problems solved by technology

As one of the commonly used feeds for beef cattle, its main disadvantages are: first, the selenium-enriched feed eaten by beef cattle is mainly enriched in plants by natural selenium-enriched soil and selenium-enriched water, while nearly 3 / 4 of our country is deficient Selenium regions have certain geographical limitations; secondly, the ability of plants to enrich selenium is weak, and the selenium content in plant branches, leaves, fruits and seeds is low, so it is difficult to transfer to beef cattle through the food chain and enrich it to a certain concentration. It takes a long time to reach the required concentration, and the time and economic cost is high

The other is to add yeast selenium to the feed as a selenium source, such as the patent 2 mentioned above. Although yeast selenium has a high concentration of selenium, it is expensive, especially for cattle farms with a large number of breeding and a large amount of food. , will increase a lot of cattle raising costs
