Problems solved by technology

However, the study found that although the indicators of protein, total amino acid and chicken fiber per unit area of ​​Ningdu Yellow Chicken are better than many broiler chickens in China, the selenium content of Ningdu Yellow Chicken is also better than that of ordinary yellow chicken breeds, but the advantage is not obvious. The invention According to human analysis, the main reason is that the body of Ningdu Yellow Chicken has not effectively absorbed selenium through rational breeding methods.

Abstract

The invention provides a method for breeding selenium-enriched Ningdu yellow chickens, aiming at the condition that the selenium content of underground water in Ningduan county in Gannhou City in Jiangxi reaches 3ug / L and is far higher than that of general underground water, selenium in water is enriched in a selenium catching agent through a selenium enrichment technology to obtain a selenium-enriched substance, and the selenium-enriched substance, conventional chicken feed and auxiliary additives in a certain proportion are granulated to obtain the selenium-enriched Ningdu yellow chickens. Meanwhile, the chickens in different growth stages are fed with three kinds of differentiated selenium-rich feed in the brooding period, the growing period and the fattening period, the problem that selenium in the selenium-rich feed is lost due to the poor selenium absorption effect can be effectively solved, the selenium-rich feed is reasonably matched, and the feed with different particle sizes is supplemented with the selenium-rich feed disintegration accelerant, so that the selenium-rich feed disintegration accelerant can be used for improving the selenium absorption effect of the chickens. Effective components of the selenium-rich feed are fully absorbed, the technical effect of increasing the selenium content of the chicken meat of the Ningdu yellow chickens is achieved, and then the quality, the nutritional value and the market competitiveness of the Ningdu yellow chickens are improved.

Description

technical field [0001] The invention belongs to the technical field of chicken breeding, and in particular relates to a method for breeding selenium-enriched Ningdu yellow chickens. Background technique [0002] Ningdu Yellow Chicken, formerly known as "Ningdu Three Yellow Chicken", is a special high-quality yellow-feathered broiler chicken. ". Ningdu yellow chickens are all carried out in the pollution-free production of forest grazing, with the characteristics of "three yellows" (beak, feathers, shanks), "five reds" (crown, beard, face, eye circles, ear leaves), etc. tender. Its indicators such as protein, total amino acid and chicken fiber per unit area are better than many domestic broiler breeds. [0003] Selenium is an essential micronutrient element for humans and animals. It has various pharmacological effects such as anti-oxidation, anti-cancer, improving body immunity, protecting the heart, protecting the liver, preventing and treating myopia and cataract, detox...
