Abstract

The invention discloses a preparation method of a selenium-enriched moringa feed additive, which comprises the following steps of: (1) moringa raw material collection and pretreatment, (2) moringa curing treatment: performing sealing fermentation on pretreated moringa coarse powder for 6-8 days at the temperature of 45-60 DEG, performing turnover and crushing for once, and performing the sealing fermentation for 2-3 days at 35-50 DEG C to form cured moringa powder with maturity of 80-87%, and (3) moringa powder drying and storage. The invention further discloses application of the selenium-enriched moringa feed additive. The prepared selenium-enriched moringa feed additive is absorbed by fish and poultry animals easily, increases a selenium content in fish and poultry meet, can further provide other rich nutrient substances, accelerates growth of the fish and poultry animals and has a wide market popularization value.

Description

【Technical Field】 [0001] The invention relates to the field of feed additives, in particular to a preparation method and application of a selenium-enriched Moringa feed additive. 【Background technique】 [0002] Selenium is an indispensable trace element for maintaining the normal functions of the human body. The lack of selenium in the human body can lead to various diseases. Modern scientific research has proved that selenium has the effects of anti-oxidation, enhancing human immunity, effectively removing harmful garbage, promoting human health, and delaying aging. Normally, the normal daily intake of selenium per person should not be less than 50 micrograms. The selenium content of ordinary fruits is extremely low and cannot meet the normal needs of the human body. Seventy-two percent of the country's areas are selenium-deficient or low-selenium areas, and more than two-thirds of the population have insufficient selenium intake to varying degrees. People who lack selenium ca...
