Selenium-enriched chicken feed and preparation method thereof

Abstract

The present invention discloses a selenium-enriched chicken feed and a preparation method thereof, and belongs to the technical field of livestock and poultry feeds. The feed is prepared from the following components in parts by weight: 120-130 parts of corn, 30-40 parts of bean cakes, 28-30 parts of fish meal, 8-10 parts of vitamin E, 50-70 parts of modified konjak refined powder, 6-8 parts of fulvic acid, 12-14 parts of malt selenium and 7-9 parts of soybean lecithin. The preparation method comprises the following steps: (1) treatment of raw materials; (2) granulation treatment; (3) preparation of embedding wall material solution; and (4) coating treatment. The prepared chicken feed has stable property, and the content of selenium in the chicken feed is obviously improved. Meanwhile, thefeed is easy to be absorbed and converted by chickens, is safe, pollution-free, and good in taste, is beneficial to improving the daily intake and laying rate of chickens, and has high market promotion value.

Description

technical field [0001] The invention belongs to the technical field of livestock and poultry feed, and in particular relates to a selenium-enriched chicken feed and a preparation method thereof. Background technique [0002] Selenium (se) is an important trace element necessary for the human body, also known as "life element" and "king of anti-cancer". It is a component of glutathione peroxidase, an indispensable trace element for the human body to maintain normal life activities. It directly participates in the synthesis and metabolism of life nucleic acid and various oxidases, and affects cell division, reproduction and genetics , has super anti-oxidation, improves human immunity, and can effectively prevent and treat more than 40 kinds of diseases including: cancer, cardiovascular disease, diabetes, improve health and delay aging. [0003] Selenium exists in two ways in nature: inorganic selenium and organic selenium. Inorganic selenium generally refers to sodium seleni...

Problems solved by technology

[0004] In recent years, people have been taking selenium-containing medicines or health care products to supplement the selenium needed by the human body. However, medicines and health care products are generally expensive, and the real and fake are hard to distinguish. The effect of selenium supplementation is not very satisfactory. Adding selenium to food Among them, selenium is supplemented while supplementing nutrition. Selenium-enriched eggs are fully enriched in selenium into eggs through biotransformation of chickens, which is convenient for human consumption and absorption.

[0005] At present, most chicken feeds are added with sodium selenite to obtain selenium-enriched eggs, but sodium selenite is highly toxic, has a narrow safety range, and low bioavailability. Too much or uneven consumption can easily lead to chicken poisoning, and too little can not be obtained. Selenium-enriched eggs, and chickens have a very low absorption rate of selenium in the existing selenium-enriched chicken feed. In addition, the existing selenium-enriched chicken feed is unstable and easy to absorb water and deteriorate
