Problems solved by technology

However, the residual inorganic selenium has a poor absorption effect for animals and has a high risk of toxicity. Improper use can easily cause selenium poisoning
[0009] The Chinese patent application with the application number 201010579798.1 discloses a kind of organic selenium-rich fish and its breeding method, but neither the selenium-rich fish nor the feed have reached a high selenium level, and the selenium content of the organic selenium-rich fish is far lower than that of the present invention. Selenium content of selenium-enriched fish
[0010] In addition, there are related news reports that fish with high total selenium content were found in the Heidingzi Reservoir of Chagan La...

Embodiment 1

[0068] In a freshwater fish breeding base, selenium-enriched fish feed was started to be fed 90 days after the fry were released. The fish feed consists of the following:

[0069] (1) Select the above-mentioned selenium-enriched corn flour, selenium-enriched broccoli powder, selenium-enriched soybean meal, imported fish meal, chicken meal, cuttlefish viscera powder, rapeseed meal, and 57% soybean meal after cleaning impurities and removing iron, respectively pulverized and passed through the diameter It is a 2 mm sieve and has been ultrafinely pulverized (the particle size is guaranteed to pass through a 100 mesh sieve);

[0070] (2) Take 5 parts of the crushed selenium-enriched corn flour, 5 parts of selenium-enriched broccoli powder, 5 parts of selenium-enriched soybean meal, 25 parts of imported fish meal, 16 parts of chicken meal, 2 parts of squid viscera powder, and 12 parts of rapeseed meal , 11 parts of 57% soybean meal;

[0071] (3) Take 3 parts of the above-mentione...

Embodiment 2

[0079] The raw materials and processing method are the same as in Example 1, and the weight ratio of each component is: 6 parts of selenium-enriched corn flour, 8 parts of selenium-enriched broccoli powder, 7 parts of selenium-enriched soybean meal, 24 parts of imported fish meal, and 17 parts of chicken meal , 2 parts of squid offal powder, 9 parts of rapeseed meal, 9 parts of 57% soybean meal, 3 parts of molasses yeast, 4 parts of full-fat soybean powder, 3 parts of soybean lecithin, 0.3 part of multidimensional compound, 0.7 part of compound mineral salt, dihydrogen phosphate 3 parts of calcium, 0.6 part of choline chloride, 1.4 parts of allicin, 2 parts of refined fish oil, the feed preparation method is the same as embodiment 1, the selenium content in the feed is 5.8 mg / kg, and the ratio of selenomethionine to total selenium is 71.3%. Selenocysteine ​​accounts for 5.6% of the total selenium.

Abstract

The invention discloses selenium-rich feed for cultivating selenium-rich fish, which is characterized in that the content of total selenium in the selenium-rich feed is 1.5-20mg/kg, wherein selenomethionine accounts for 60%-80% of the total selenium, and selenocysteine accounts for 1%-10% of the total selenium. The selenium content of the selenium-rich fish cultivated by the selenium-rich feed is stable and controllable (the meat selenium content can reach to 1.5-10.0mg/kg, and the proportion of organic selenium is larger than or equal to 80 %), the selenium is safe in form and good in absorption effect, and patients lack of the selenium can improve the condition of lack of the selenium in a short time by eating the selenium-rich fish. In addition, a selenium-rich method is easy to popularize, and large-scale production can be achieved.

Description

technical field [0001] The invention relates to aquatic products, in particular to a method for cultivating selenium-enriched fish and selenium-enriched feed, and belongs to the technical field of aquatic products 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, Antagonize heavy metals in the body. The United Nations Health Organization announced at the Beijing Conference in 1996: "Selenium is an essential trace element for the human body." One-third of my country's population has insufficient selenium intake to varying degrees. Our nutrition society recommends an adult daily intake of 50-250 micrograms , but the intake of adults in my country is only 26-50 micrograms, and about 70% of China's population is in a selenium-deficient area [0003] Selenium is...
