Cultivating method for selenium-rich feed and selenium-rich abalone

Abstract

The invention discloses a cultivating method for selenium-rich feed and a selenium-rich abalone. The total selenium content of the selenium-rich abalone is 200 to 1500 Mug / kg, wherein the organic selenium content is greater than or equal to 80 percent. The cultivating method for the selenium-rich abalone comprises the steps that the organic-selenium-rich feed is fed to the abalone every day, wherein the organic-selenium-rich feed comprises following components by weight part: 2 to 6 weight parts of ground high-selenium corn flour, 1 to 5 weight parts of ground high-selenium wheat flour, 1 to 5 weight parts of ground high-selenium soybean flour, and 89 to 98 weight parts of conventional abalone feed; and the selenium content of the organic-selenium-rich feed is in the range of 300 mu g / kg to 1000 mu g / kg. The abalone cultivated by using the cultivating method is rich in selenium elements and integrally has a uniform selenium content; and the cultivating method disclosed by the invention has the advantages that the selenium content and the organic selenium proportion of an edible part of the abalone are increased and standardized large-scale production can be realized.

Description

technical field

[0001] The invention relates to a selenium-enriched feed and a method for cultivating selenium-enriched abalone, in particular to an organic-selenium-rich abalone and a method for cultivating the organic-selenium-rich abalone. 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, Reduce morbidity, improve production performance, improve meat quality evaluation, and at the same time antagonize heavy metals in the body. Selenium is used in aquaculture to remove free radicals in animals and make them more energetic. 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 ...
