Selenium-rich pig feed as well as preparation method and application thereof

Abstract

The invention discloses a selenium-rich pig feed. The selenium-rich pig feed comprises selenium-rich raw materials and main materials, wherein the selenium-rich raw materials are prepared from the following raw materials: selenium-rich corn, selenium-rich alfalfa, selenium-rich day lilies, selenium-rich astragalus membranaceus, selenium-rich gynostemma pentaphyllum, selenium-rich milk vetch, and selenium-rich sweet potato leaves; the main materials are prepared from the following raw materials: soybean meal, peanut meal, fish meal, bone meal, middling, soybean oil, table salt, lysine, methionine, valine, complex vitamins, choline chloride, a mycotoxin adsorbent and complex trace elements. The invention further discloses a preparation method of the selenium-rich pig feed. The preparation method comprises the steps of crushing, mixing and the like. The invention further discloses an application method of the selenium-rich pig feed. Before 40-80 days when porkers become full-grown and are ready for slaughter, the selenium-rich pig feed is fed according to the normal feeding number of pigs. According to the selenium-rich pig feed disclosed by the invention, selenium-rich Chinese herbal medicine ingredients are added, so that the nutrition is balanced, the immunity of the pigs can be improved, and the selenium content of pork is increased. The preparation method is simple. The selenium-rich pig feed disclosed by the invention is scientific and reasonable in application method, and the breeding benefits of the pigs can be increased.

Description

technical field [0001] The invention relates to a poultry breeding feed and its preparation method and application, in particular to a selenium-enriched pig feed and its preparation method and application. Background technique [0002] Selenium is an essential trace element for humans and animals, which can improve the immunity of humans and animals, and has anti-oxidation and anti-aging effects. Humans mainly supplement selenium through food intake. Pork has a good accumulation effect on selenium, and because it is the main meat food for most people in my country, selenium nutrition can be strengthened in the process of raising pigs, and the purpose of supplementing selenium in the human body can be achieved by eating selenium-enriched pork. [0003] Selenium is divided into organic and inorganic selenium. The selenium-enriched pork currently produced in the market is fed with sodium selenite and yeast selenium in the feed to feed pigs. This type of inorganic selenium is h...

Problems solved by technology

[0003] Selenium is divided into organic and inorganic selenium. The selenium-enriched pork currently produced in the market is fed with sodium selenite and yeast selenium in the feed to feed pigs. This type of inorganic selenium is highly toxic and difficult to be absorbed. It is not suitable for human and animal use; due to the increasing number of various diseases of pigs, farmers add large doses of antibiotics to pig feed in order to improve the immunity of pigs in order to save costs, and the residual antibiotics in pork exceed the standard, which will also directly affect to human antibiotic resistance
