Se-enriched feedstuff containing selenium element and uses thereof

Abstract

The invention relates to a feed with rich selenium, which comprises the raw materials of 10 to 100 portions of black food, 1 to 20 portions of seafood and 5 to 50 portions of Chinese herb extracts. The application method is that: 3 to 10 percent of the feed with rich selenium is stirred into normal chicken feed and the mixture feed can feed chicken after even stirring and mixing with labors or machines. After 5 to 10 days, eggs are sent for detection and the content of selenium of the eggs is between 2.0 to 2.5PPM. Compared with normal eggs, eggs produced by the chicken fed with the feed with rich selenium contain 60 to 80 mg of selenium per egg, besides high selenium content, the eggs have high content of beneficial elements of calcium and zinc and reduce the content of harmful elements of lead and mercury. The technical characteristics do not exist in the prior art.

Description

technical field [0001] The invention belongs to the technical field of feed production, and relates to a feed additive containing selenium, more specifically, the invention relates to a selenium-rich feed containing selenium and its production method and application. Background technique [0002] Selenium is an essential trace element for the human body. Diseases such as cancer, liver disease, cardiovascular and cerebrovascular diseases, diabetes, cataracts, and low immunity are closely related to selenium. my country is a big selenium-deficient country. There are two-thirds of selenium-deficient areas in the country, and one-third of the areas are severely selenium-deficient areas. Residents in selenium-deficient areas, due to selenium deficiency in local water and soil, cause selenium in edible grains, vegetables, and fruits. Insufficient content has long caused the selenium level in human blood to drop, which can easily cause cardiovascular and cerebrovascular diseases, di...

Problems solved by technology

[0004] There are quite a few selenium-supplementing foods that have been put on the market in my country, but there are two problems: one is that the selenium content of the products is low, and because the selected feed additives have different composition ratios, the contained feed additives are absorbed by the animal body. The situation is different, causing the selenium content of the eggs to be low, and the requirement of quantitative selenium supplementation cannot be met according to normal consumption; the second is that the price is too expensive, and the normal daily intake of selenium per person according to the World Health Organization is 50-250 micrograms, The lowest price is about 10 yuan per day, and the highest is 30 yuan. Therefore, the economic burden is too heavy for most consumers, which affects the promotion and consumption of selenium-enriched eggs.
