Manufacturing method of selenium-rich chicken feed

Abstract

The invention discloses a manufacturing method of a selenium-rich chicken feed, which comprises the following steps: A. preparation of animal viscera powder: selecting animal viscera, cleaning, boiling, pulverizing by a pulverizer, drying at 70-80 DEG C, and passing through a 80-100-mesh screen to obtain animal viscera powder; B. preparation of purple sweet potato powder: selecting purple sweet potatoes, cleaning, dicing, pulverizing, and drying to obtain the purple sweet potato powder; C. mixing seaweed meal, the animal viscera powder and purple sweet potato powder, adding amylase, polypeptide, phytase and xylanase, and stirring for 35-40 minutes; and D. pulverizing lily root to obtain lily root flour, adding the lily root flour into the substance obtained in the step C, adding 3 parts of salt, and mixing to obtain the selenium-rich chicken feed. The manufacturing method is simple, easy in product proportioning and convenient to use; and the selenium replenisher is organic selenium with high absorptivity, thereby obviously enhancing the rich selenium content in eggs.

Description

[0001] Technical field: [0002] The invention relates to the technical field of feed, in particular to a method for manufacturing selenium-enriched chicken feed. [0003] Background technique: [0004] Selenium is known by scientists as the "king of anti-cancer" among the trace elements in the human body. Research in the scientific community has found that the level of blood selenium is closely related to the occurrence of cancer. A large number of survey data show that the level of selenium content in food and soil in a region is directly related to the incidence of cancer. Therefore, people often like to choose some selenium-rich foods. As eggs, if the selenium content of eggs is increased, Only by supplementing the selenium element in the feed, after the chickens use the selenium-enriched chicken feed, the selenium content of the eggs can be significantly increased after self-absorption. However, the selenium added to the current selenium-rich chicken fines Most supple...

A large number of survey data show that the level of selenium content in food and soil in an area is directly related to the incidence of cancer. Therefore, people often like to choose some selenium-rich foods. As eggs, if the selenium content of eggs is increased, Only by supplementing the selenium element in the feed, after the chickens use the selenium-enriched chicken feed, the selenium content of the eggs can be significantly increased after self-absorption. However, the selenium added to the current selenium-rich chicken fines Most of the supplements are inorganic selenium, which has poor absorption rate
