[0006] The Chinese patent "A Production Method of Selenium-enriched Milk and Concentrated Feed Rich in Organic Selenium" (authorized announcement number: CN1282421C) discloses a method for producing selenium-enriched milk, but the selenium source used in the invention is selenous acid or Sodium selenite, the absorption effect of inorganic selenium is poor and has certain toxicity, and the effect of enriching selenium in the living body is not as good as that of organic selenium, and it is easy to cause pollution to the environment
[0007] Chinese patents CN1439283A, CN101081063A, CN101940258A, CN101744139A, and CN101331916A disclose dairy or beef cattle feed and preparation methods thereof, which basically belong to feed or additives with conventional nutritional element ratios, and cannot effectively improve the selenium content of beef
[0009] "Comparison of the effects of selenium-enriched broccoli and selenium-enriched corn on the selenium status of rat tissues" (Kong Linghong et al., Trace Elements and Health Research, Volume 18, No. 1, Pages 10-12) discloses that selenium-enriched broccoli and selenium-enriched Selenium-enriched grains such as corn can be used as selenium supplements, but there is no in-depth research and description on the form of selenium and the effect on animal organisms.

Embodiment 1

[0057] In a Simmental cattle breeding base, the organic selenium-rich concentrate of the present invention was fed to beef cattle at the age of 7 months, and the beef cattle grew to 13 months of age, and beef cattle fed with ordinary concentrate were used as a control. The components of the rich organic selenium concentrate are 5 parts of selenium-enriched corn flour, 3 parts of selenium-enriched broccoli flour, 34 parts of ordinary corn flour, 5 parts of bran, 35 parts of wheat straw flour, 5 parts of rice bran, and cotton seed cake according to the weight fraction ratio. 12 parts, 1 part bone meal, 1 part salt, 1 part additive. The above-mentioned selenium-enriched corn flour and selenium-enriched broccoli powder were purchased from Suzhou Segu Technology Co., Ltd., and the remaining components are available in the market.

[0058] The ratio of each component of the additive in parts by weight is: 4 parts of zinc sulfate, 5.2 parts of ferrous sulfate, 0.55 parts of anhydrous co...

Embodiment 2

[0064] In a certain Angus cattle breeding base, the organic selenium-rich concentrate of the present invention was fed to beef cattle at the age of 7 months, and the beef cattle grew to 13 months of age, and beef cattle fed with ordinary concentrate were used as a control. The components of the rich organic selenium concentrate are 7 parts of selenium-enriched corn flour, 4 parts of selenium-enriched broccoli flour, 31 parts of ordinary corn flour, 4 parts of bran, 33 parts of wheat straw flour, 6 parts of rice bran, and cotton seed cake. 12 parts, 1 part bone meal, 1 part salt, 1 part additive. The above-mentioned selenium-enriched corn flour and selenium-enriched broccoli powder were purchased from Suzhou Segu Technology Co., Ltd., and the remaining components are available in the market.

[0065] The ratio of each component of the additive in parts by weight is: 4 parts of zinc sulfate, 5.2 parts of ferrous sulfate, 0.55 parts of anhydrous copper sulfate, 0.48 parts of potassi...

Embodiment 3

[0071] In a Hayford cattle breeding base, the organic selenium-enriched concentrate of the present invention was fed to beef cattle at the age of 7 months, and the beef cattle grew to 13 months of age. The beef cattle fed with ordinary concentrate were used as a control. The components of the organic selenium concentrate feed are 9 parts of selenium-enriched corn flour, 7 parts of selenium-enriched broccoli flour, 28 parts of ordinary corn flour, 5 parts of bran, 31 parts of wheat straw flour, 6 parts of rice bran, and cottonseed cake. 11 parts, 1 part bone meal, 1 part salt, 1 part additive. The above-mentioned selenium-enriched corn flour and selenium-enriched broccoli powder were purchased from Suzhou Segu Technology Co., Ltd., and the remaining components are available in the market.

Abstract

The invention discloses a production method for beef rich in organic selenium and a concentrated feed rich in organic selenium. The selenium content of the beef rich in organic selenium is 200-1000 microgrammes / kg, wherein the content of the organic selenium is more than or equal to 85%. The method comprises the following steps of: selecting a healthy meat cattle under the fattened early stage; feeding 200-1000 microgrammes / kg of total selenium each day; and feeding with the concentrated feed of which the selenomethionine accounts for 60-80% of the total selenium ratio and the selenocysteine accounts for 1-10% of the total selenium ratio until fattening. The meat of the cattle fed with the method is the beef rich in organic selenium. The beef rich in organic selenium, which is disclosed by the invention, has the advantages of stable and controllable content, safer form and better adsorption effect, the selenium enriching method is easy to popularize, and large-scale production can be carried out.

Description

Technical field [0001] The invention relates to a production method of selenium-enriched beef, in particular to a production method of organic-selenium-enriched beef and an organic-selenium-enriched concentrate feed, belonging to the technical field of meat and feed production. Background technique [0002] Selenium is an essential trace element in animals. It has strong antioxidant properties and is an important part of the antioxidant enzyme glutathione peroxidase (GSH-PX) in the body. It can improve the body's immunity. Selenium is generally divided into two categories: inorganic selenium and organic selenium: the former includes selenate, selenite, etc. Inorganic selenium has poor absorption effect for humans and animals, and has a high risk of toxicity. Improper use can easily cause selenium poisoning; It mainly refers to the form of selenium combined with biological organic molecules. For humans and animals, the absorption rate of organic selenium is high, the toxicity risk...
