Abstract

The present invention discloses a preparation method of a selenium-enriched feed for penaeus vannamei. The preparation method comprises the following steps: squid paste, corn flour, mussel meat meal, wheat bran, sorghum powder, distillers' grains, lecithin, animal oil, wheat germ oil, edible salt, selenium-enriched yeasts, flavonoids and an oenothera biennis extract are prepared into a first mixture, then the mixture is mixed with an animal internal organ slurry liquid, the mixture is subjected to a vacuum sintering treatment, Chinese herbal medicines are added, the materials are mixed, the mixture is subjected to a fermentation, then a medium and trace element microemulsion and ultra-fine mineral powder soaked by selenium-enriched amino acids are used to conduct two film-forming treatments, and the selenium-enriched feed for the penaeus vannamei is obtained. The feed can improve a selenium content of penaeus vannamei meat, improves appetite, feed intake and disease resistance of the penaeus vannamei, further improves growth rates and survival rates of the penaeus vannamei, and can significantly improve health-care functions of the penaeus vannamei and economic income of farmers.

Description

technical field [0001] The invention relates to the field of prawn feed, in particular to a preparation method of selenium-rich Penaeus vannamei feed. Background technique [0002] Selenium is an essential trace mineral element to maintain human health. It has a strong antioxidant effect, can remove lipid peroxides and free radicals in the body to protect cell membranes, improve the body's immunity and disease resistance, and protect the body against foreign harmful substances. Once the selenium intake of the human body is insufficient, it will easily cause various diseases, such as the occurrence of Keshan disease. The absorption rate of organic selenium is as high as 80%, which is 1.6 times higher than that of inorganic selenium (sodium selenite, etc.), and it has the functions of scavenging free radicals, stimulating immunoglobulin, protecting lymphocytes, enhancing immune function, delaying aging and promoting children's development and growth. effect. There are very f...
