Problems solved by technology

[0006] (1) Only adding yeast selenium and selenium-enriched corn to feed is considered, but due to technical reasons, adding selenium to livestock and poultry drinking water is not considered
[0007] (2) Although the absorption and utilization rate of organic selenium mainly composed of yeast selenium is higher than that of inorganic selenium mainly composed of sodium selenite, the main valence state of its selenium element is still dominated by +2 valence, which is the same as the main valence state of selenium element. Compared with the water-soluble protein selenium in the state of zero valence, there is still a certain gap in the absorption and utilization rate.

Embodiment 1

[0028] (1) Dilute the water-soluble protein selenium with a selenium content of 0.2% with 20 times of water to obtain the diluted water-soluble protein selenium A, add A to the irrigation water in an amount of 1%, and spray it on the east of the pasture every day. In the forage on the side, after 4 months, the selenium content of the forage was detected to be 0.3mg / kg, and the selenium-enriched forage was collected for free feeding of chickens;

[0029] (2) The formula of selenium-enriched drinking water for chickens is: use selenium content of 0.3% water-soluble protein selenium, dilute it with 20 times of water to obtain diluted water-soluble protein B, add B to the chicken in an amount of 4% The theoretical drinking water selenium content is 0.12mg / kg, and the measured drinking water selenium content is 0.13mg / kg;

[0030] (3) According to the age of the chicks, the following different formula supplements are used for feeding:

Embodiment 2

[0036] (1) Dilute the water-soluble protein selenium with a selenium content of 0.3% with 50 times of water to obtain the diluted water-soluble protein selenium A, add A to the irrigation water in an amount of 1%, and spray it on the west of the pasture every day In the forage on the side, after 4 months, the selenium content of the forage was detected to be 0.15mg / kg, and the selenium-enriched forage was collected for the chickens to eat freely;

[0037] (2) The formula of selenium-enriched drinking water for chickens is: water-soluble protein selenium with a selenium content of 0.3% is used, diluted with 10 times of water to obtain diluted water-soluble protein B, and B is added to chickens in an amount of 2%. In the drinking water, the theoretical drinking water selenium content is 0.12mg / kg, and the measured drinking water selenium content is 0.12mg / kg;

Embodiment 3

[0044] (1) Dilute the water-soluble protein selenium with a selenium content of 0.1% with 50 times of water to obtain the diluted water-soluble protein selenium A, add A to the irrigation water at a dosage of 3%, and spray it on the south of the pasture every day. In the forage on the side, after 4 months, the selenium content of the forage was detected to be 0.25 mg / kg, and the selenium-enriched forage was collected for the chickens to eat freely;

[0045] (2) The formula of selenium-enriched drinking water for chickens is: water-soluble protein selenium with a selenium content of 0.3% is used, diluted with 10 times of water to obtain diluted water-soluble protein B, and B is added to chickens in an amount of 2%. The theoretical drinking water selenium content is 0.11mg / kg, and the measured drinking water selenium content is 0.13mg / kg.

Abstract

The invention discloses a breeding method of antibiotics and hormones-free selenium-enriched chicken. The method comprises following steps: (1) selenium-enriched forage grass selecting: diluting water-soluble protein selenium to obtain water-soluble protein selenium solution and spreading the solution on forage grass inside a farm once a week, and collecting and storing the selenium-enriched forage grass after four months for free feeding of chicken; (2) fodder selecting: natural grain and the selenium-enriched forage grass collected in step (1) are used as breeding fodder; (3) drinking water preparing: water-soluble protein selenium is added to drinking water for chicken according to prescribed ratio; (4) breeding environment: free-ranging covers the whole breeding process and no antibiotic and medicinal component is used. The bred chicken has no side effect and is non-toxic; the chicken has high selenium content, good taste, and meets the dual requirement of health and delicacy.

Description

technical field [0001] The invention belongs to the technical field of breeding, and in particular relates to a breeding method for non-resistant selenium-enriched chickens. Background technique [0002] my country is a selenium-poor country, and 72% of the regions are in selenium-deficient areas. The daily selenium intake recommended by the World Health Organization is 400 micrograms, and the daily selenium intake recommended by the Chinese Nutrition Society is 50-250 micrograms. Chinese people can only take in 17-30 micrograms of selenium from their diet every day. Selenium, as one of the 15 essential nutrients for the human body, is an excellent anti-peroxidation substance and has a good effect on malnutrition caused by lack of protein. Insufficient selenium intake in the human body, mild and moderate effects or not obvious, but severe deficiency can easily lead to cardiovascular diseases, diabetes, hypertension and other diseases. [0003] In the past, selenium supplement...
