Description

Micromolecular selenium protein livestock feed and preparation method thereof
Technical Field
The invention relates to the technical field of livestock breeding, in particular to a feed for livestock breeding.
Background
Selenium is an important component of antioxidant enzyme (glutathione peroxidase) and selenium-P protein in animals and human bodies, plays a role in balancing oxidation-reduction atmosphere in vivo, and researches prove that the selenium has the function of improving the immunity of animals. Selenium is one ten million in human tissues, but the selenium determines the existence of life, and the selenium has great effect on human health and cannot be replaced by other substances. The selenium deficiency can directly lead to the reduction of the immunity of human bodies, and more than forty diseases threatening the health and the life of human bodies are proved to be related to the selenium deficiency of human bodies by clinical medicine, such as cancers, cardiovascular diseases, liver diseases, cataract, pancreatic diseases, diabetes, reproductive system diseases and the like. According to the examination of experts, people need to supplement selenium for a lifetime. Both animal experiments and clinical practices indicate that sufficient selenium should be continuously obtained from the diet and cannot be supplemented in time, so that the disease-removing capability is reduced. A person should have to take a sufficient amount of selenium each day, like starch, protein and vitamins each day.
At present, people mainly take selenium tablets, or eat selenium-rich plants and selenium-rich livestock (such as livestock meat, eggs and the like) to supplement selenium. However, since most of selenoproteins in selenium-enriched plants and selenium-enriched sheets are vegetable selenoproteins, the absorption of vegetable selenoproteins in human bodies is not ideal compared with animal selenoproteins (the structure of which is closer to that of human bodies, so the absorption of vegetable selenoproteins in human bodies is high), and therefore people still want to achieve the purpose of selenium supplement by eating meat quality and eggs of animals such as poultry and livestock. However, the selenium content of the livestock and poultry bred by the existing breeding technology is generally low, and the selenium content naturally absorbed into human bodies is not high. That is, in order to truly achieve the purpose of selenium supplement, we need to first improve the selenium content of foods, especially the selenium content of the meat of poultry, livestock and poultry and eggs.
Disclosure of Invention
The invention provides a micromolecule selenium protein livestock feed and a preparation method thereof, and the micromolecule selenium protein livestock feed can greatly improve the meat quality of livestock and the selenium content of eggs of the livestock.
In order to solve the technical problems, one of the technical schemes adopted by the invention is as follows:

Further, the mass ratio of the mixture to water is 1: 1.
Further, the mass ratio of the component A to the component B is 0.5-4: 0.5-4.
The second technical scheme adopted by the invention is as follows:

In the above technical solution, a more specific technical solution is: the method comprises the following steps:
A. mixing raw materials of corn, barley, rice bran, bean pulp, cottonseed meal, yeast selenium, malt selenium and complex enzyme to obtain a mixture, then putting the mixture into a sealed container, adding water, sealing, standing and fermenting to obtain a component A for later use; wherein the complex enzyme comprises xylanase and beta-glucosaccharase; the component A comprises the following raw materials in parts by weight of 2-5 parts of corn, 3-6 parts of barley, 0-5 parts of rice bran, 0-3 parts of bran, 0-1 part of soybean meal, 0-2 parts of cottonseed meal, 0.1-0.3 part of yeast selenium, 0.1-0.5 part of malt selenium and 0.1-0.3 part of complex enzyme;

Further, the mass ratio of the mixture to the water in the step A is 1: 1.

Due to the adoption of the technical scheme, the invention has the beneficial effects that:
1. the livestock feed is micromolecular selenium protein livestock feed which is easily digested and absorbed by livestock and converted into selenium content of the livestock, so that the meat quality of the livestock and the selenium content of eggs of the livestock are greatly improved.
2. The invention firstly utilizes the yeast selenium added in the raw materials of the livestock feed to ferment, the yeast selenium and the malt selenium are fermented and decomposed into micromolecular selenium protein, then the existence of the malt selenium is utilized to provide a sugar source for the yeast selenium, and the secondary fermentation process of the yeast selenium is realized, so the yeast selenium and the malt selenium are more fully decomposed to obtain more micromolecular selenium protein, the selenium content in the livestock feed is improved, meanwhile, the molecular weight of the selenium protein is smaller due to the multiple fermentation caused by the addition of the yeast selenium and the malt selenium, the selenium protein is easier to be absorbed by the livestock eating the feed and is converted into the selenium content of the meat quality or eggs of the livestock, and the aim of improving the selenium content of the meat quality and eggs of the livestock is achieved.
3. The micromolecular selenoprotein in the livestock feed is organic selenium type selenoprotein, which is beneficial to the absorption of selenium by livestock per se, promotes the enrichment of selenium in the livestock, can also improve the immunity of the livestock and enhance the prevention and treatment effect of livestock diseases, thereby ensuring the survival rate and the egg laying rate of the livestock and poultry.
4. On the basis of reducing the consumption of high-cost raw materials such as corn and soybean meal in the original livestock feed, a large amount of low-cost raw materials such as rice bran and cottonseed meal are added, and then the complex enzyme with the function of decomposing plant cell walls is added, so that the raw materials such as the rice bran and the cottonseed meal can be fully decomposed and fermented into components which can be easily eaten and absorbed by livestock while the yeast selenium is fermented, and the cost of the livestock feed is reduced.
