Selenium-rich chicken feed and preparation method thereof

Abstract

A selenium-rich chicken feed belongs to the field of feeds and is composed of the following raw materials: rice bran, corn, haw, cordate houttuynia, Chinese yam, carrot, grape pomace, purple sweet potato, lycium ruthenicum slag, garlic, dried orange peel, Chinese sauerkraut, rotten vegetable leaves, domestic fungus and distillers' grains. The method for preparing the selenium-rich chicken feed comprises the following steps: (1) fetching rice bran, corn, haw, Chinese yam, carrot, purple sweet potato, garlic and dried orange peel and respectively crushing; (2) fetching cordate houttuynia, grape pomace, lycium ruthenicum slag, Chinese sauerkraut, rotten vegetable leaves, domestic fungus and distillers' grains and carrying out composting fermentation; and (3) uniformly mixing all the raw materials, granulating, and drying. Chicken bred with the selenium-rich chicken feed is rich in selenium and is healthy and safe.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a selenium-enriched chicken feed and a preparation method thereof. Background technique [0002] Selenium is an important trace element in the human body, which can resist aging and maintain vitality; the important physiological functions of selenium on the human body have attracted more and more attention from scientists from all over the world, and all countries have formulated recommended intakes of selenium nutrition according to their own conditions. At present, the commonly used selenium supplement methods for the human body mainly include taking sodium selenite, eating iodized salt, etc., but because these methods are difficult to control the intake and have potential toxicity and other reasons, they have obvious limitations; people from the perspective of long-term and safety At present, people are discussing the production of selenium-rich agricultural products, so that peo...

AI Technical Summary

Problems solved by technology

[0004] At present, most selenium-enriched chickens are fed with selenium-enriched selenium salts and other inorganic selenium salts directly in the feed. Although it can increase the selenium content in the feed, the inorganic selenium salts are more toxic and can easily cause selenium in poultry eggs. Poisoning, if long-term consumption of eggs containing inorganic selenium salt feed, it will endanger human health

This single addition of inorganic selenium in the feed will lead to the production of selenium-enriched chickens with food safety hazards
