Production method for selenium-rich cow feed and selenium-rich milk

Abstract

The invention discloses a production method for selenium-rich cow feed and selenium-rich milk. Selenium content of organic-selenium-rich milk is 100-500 mug / kg, and organic selenium content >=80%. The method includes that healthy cows beginning to produce milk are selected and fed with organic-selenium-rich concentrated feed for 7-10 days, and milk produced by the cows fed in the method is organic-selenium-rich milk. The organic-selenium-rich concentrated feed for producing the organic-selenium-rich milk comprises 3-10 parts of high-selenium corn starch, 3-15 parts of high-selenium broccoli powder, 25-35 parts of common corn starch, 3-7 parts of bran, 30-40 parts of wheat straw, 3-7 parts of rice chaff, 8-16 parts of cottonseed cake, 0.5-1.5 parts of bone meal, 0.5-1 part of salt and 0.5-1.5 parts of additives. The organic-selenium-rich milk is stable and controllable in selenium content, safe in form and good in absorbing effect. The selenium enriching method is easy to popularize and suitable for massive production.

Description

Technical field [0001] The invention relates to selenium-enriched milk and a production method thereof, in particular to a production method of organic-rich selenium milk and an organic-rich selenium concentrate feed, belonging to the technical field of milk 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 ris...

[0004] The Chinese patent "A Production Method of Selenium-Enriched Milk" (publication number: CN101433239A) discloses a method of adding selenium powder to milk to produce selenium-enriched milk. The method of directly adding it to milk is currently under food safety control conditions. It cannot be implemented in production practice

[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 organic selenium
