Abstract

The present invention provides a method for producing a selenium-enriched feed additive. The method consists of the following steps: (1) selenium-enriched yeasts, plant stalks, fruits, vegetables, mulberry leaves and wheat brans are mixed, and the mixture is fermented to obtain fermentation products; (2) the fermentation products are used to feed grass-eating fly larvae, tenebrio molitor larvae or silkworm larvae to obtain chicken edible pupae; (3) the chicken edible pupas are added into a chicken basic feed to feed chickens and chicken manure produced by the chicken is collected; (4) chicken feathers of the chicken manure are removed, the feather removed chicken manure is dehydrated, and the dehydrated chicken manure is used for feeding grass-eating fly larvae, tenebrio molitor larvae or silkworm larvae to obtain feed pupae; and (5) the feed pupae is separated, the separated feed pupae is dried in a conventional manner, the dried feed pupae is crushed, and the crushed feed pupae is granulated to obtain the selenium-enriched feed additive. The present invention also provides a use of the selenium-enriched feed additive for feeding fish.

Description

technical field

[0001] The invention relates to a method for producing a selenium-enriched feed additive. Background technique

[0002] Selenium (Se) is an essential trace element for the human body and has important physiological functions. It can prevent and inhibit tumors, resist aging, maintain the normal structure and function of the cardiovascular system, prevent arteriosclerosis and coronary heart disease, and has anti-oxidation and anti-tumor properties. and enhance immunity. Currently known human diseases related to selenium deficiency include cancer, cardiovascular and cerebrovascular diseases, diabetes, liver disease, high blood pressure, and sexual dysfunction. The Chinese Nutrition Society recommends that the daily selenium intake of Chinese people from the diet is 50-250 micrograms, and the daily selenium intake recommended by the World Health Organization is 400 micrograms. my country is a selenium-poor country, 72% of the area is in the soil selenium-poor z...
