Feed for selenium-rich pigs

Abstract

The invention relates to a feed for selenium-containing pigs. The feed comprises corns, wheat bran, vegetable oil, bean meal and a selenium-containing premixed feed, wherein the selenium-containing premixed feed is a high-selenium formula feed prepared from selenium-containing materials, multiple vitamins and Chinese herbal medicines; the Chinese herbal medicines mainly comprise rhizoma coptidis, Shiyao angelica sinensis, Enshi Banqiao radix codonopsis, cortex eucommiae and wild vegetables. The feed is nutrient, healthy and safe; the meat quality can be improved, and the content of selenium of pork is high, so that the content of the selenium of a human body can be increased; besides, the culture benefit can be increased, the daily gain of the pigs can be increased, the material weight ratio is remarkably decreased, and the immunologic functions of the pigs can be enhanced.

Description

technical field [0001] The invention relates to a feed in the field of breeding industry, in particular to a feed capable of producing selenium-rich pork. Background technique [0002] Selenium is an essential trace element for humans and animals, lack of which can seriously affect health. According to the survey by the Chinese Academy of Sciences, there are as many as 22 selenium-deficient provinces in China, and 28% of the counties and cities are seriously deficient in selenium. Most of the population in China now lives in a serious selenium-deficient environment. Because about 72% of the country's land area is selenium-deficient in soil, relying on natural food to supplement selenium cannot meet the needs of humans and animals for selenium. Pork accounts for more than 63% of residents' meat consumption, and the research and development of selenium-enriched pork is of great significance to the human body's selenium supplementation. [0003] Studies in recent years have s...
