Fish feed selenium cream and use method thereof

Abstract

The invention relates to fish feed selenium cream and a use method thereof. The fish feed selenium cream is characterized by being prepared by breaking 1 part of eggs, stirring at a high speed, adding 1-3 parts of liquid edible grease, and slowly adding a selenium source when stirring is carried out, thereby obtaining the cream, wherein the selenium source content is 50-400mg / kg in the prepared fish feed selenium cream; the prepared fish feed selenium cream is preserved at 4 DEG C; the selenium source is one or multiple of selenium-enriched yeast, selenoprotein, selenium-polysaccharide and high polymeric selenium plant powder with the selenium content greater than 2000mg / kg, and ultra-polymeric microorganisms and nano-selenium with the selenium content greater than 30000mg / kg. The fish feed selenium cream has the beneficial effects that selenium-enriched fish can be bred after fish is fed with the fish feed selenium cream for 20 days or a longer time continuously before killing, and the selenium content of fish is 0.20-2.0mg / kg (the control selenium content of fish without selenium cream is equal to or lower than 0.20mg / kg, and the eating value and the disease resistance of fish can be improved).

Description

technical field [0001] The invention relates to a fish feed selenium cream and a using method thereof. Background technique [0002] Fish is people's favorite food. It has high nutritional value and is easy to digest and absorb. Fish resources are very rich in the world, and they are distributed in rivers, lakes, and cold and warm waters. , the selenium content of farmed commercial fish is not high, and the selenium content of different growth ages and different types of fish is different. The selenium content of fish below 3kg is generally below 0.20mg / kg, and it is unstable, and the selenium content is not enough. control. According to the test results of the selenium content in the feed and water, the analysis shows that: fish have strong selenium accumulation ability, can absorb and transform the selenium in the water and feed into organic selenium and store it in the fish body, providing human beings with safety, High-grade bio-organic selenium. The selenium sources ...
