Embodiment 1

[0021] This embodiment provides a kind of selenium-enriched Peking chicken egg and its production method: prepare selenium-enriched premixed feed with selenium-containing yeast selenium of 3000 mg / kg, and add 10 kg of selenium-enriched premixed feed per ton of feed to prepare Selenium-enriched compound feed was fed to 72 egg-use Beijing oil chickens aged 22 to 65 weeks for 7 consecutive days to obtain selenium-enriched Beijing oil chicken eggs, and the selenium content of the eggs could reach 0.33mg / kg.

[0022] In this example, the breeding temperature of Beijing oil chicken is 18-28°C, the humidity is 50%-70%, the light time is 16-18h / d, the light intensity is 13-14 lux, and the daily feed intake is 75g-70%. Between 95g.

[0023] In the present embodiment, the selenium-enriched premixed feed contains 2 kg of phytase (5000 G) per 100 kg, 1 kg of Bacillus subtilis, 3.6 kg of multidimensional for laying hens, 8 kg of 50% choline chloride, 10 kg of methionine, pentahydrate Copp...

Embodiment 2

[0026] This embodiment provides a kind of selenium-enriched Peking chicken egg and its production method: prepare selenium-enriched premixed feed with selenium-containing yeast selenium of 3000 mg / kg, and add 10 kg of selenium-enriched premixed feed per ton of feed to prepare Form a selenium-enriched compound feed, feed 72 egg-use Beijing oil chickens aged 22 to 65 weeks, and feed them continuously for 14 days to obtain selenium-enriched Beijing oil chicken eggs, and the selenium content of the eggs can reach 0.40mg / kg.

[0027] In this example, the breeding temperature of Beijing oil chicken is 18-28°C, the humidity is 50%-70%, the light time is 16-18h / d, the light intensity is 13-14 lux, and the daily feed intake is 75g-70%. Between 95g.

[0028] Contain phytase (5000G) 2kg in every 100kg in the selenium-enriched premixed feed described in the present embodiment, Bacillus subtilis 1kg, multidimensional 3.6kg special for laying hens, 50% choline chloride 8kg, methionine 10kg,...

Embodiment 3

[0031] This embodiment provides a kind of selenium-enriched Peking chicken egg and its production method: prepare selenium-enriched premixed feed with selenium-containing yeast selenium of 3000 mg / kg, and add 10 kg of selenium-enriched premixed feed per ton of feed to prepare Selenium-enriched compound feed was fed to 72 egg-use Beijing oil chickens aged 22 to 65 weeks for 14 consecutive days to obtain selenium-enriched Beijing oil chicken eggs, and the selenium content of the eggs could reach 0.48mg / kg.

[0032] In this example, the breeding temperature of Beijing oil chicken is 18-28°C, the humidity is 50%-70%, the light time is 16-18h / d, the light intensity is 13-14 lux, and the daily feed intake is 75g-70%. Between 95g.

Abstract

The invention provides a selenium-enriched Peking oil chicken egg, the selenium content of the selenium-enriched Beijing oil chicken egg can reach 0.30 mg / kg-0.50 mg / kg, and the production method of the selenium-enriched Beijing oil egg is as follows: firstly, yeast selenium is used to Prepare selenium-enriched feed with a selenium content of 0.28mg to 0.50mg / kg, and then use the selenium-enriched feed to feed 22-65-week-old Beijing oil chickens for eggs. After feeding for 7-14 days, Beijing oil chickens for eggs can produce selenium. Selenium-enriched Beijing oil eggs with a content of 0.3mg / kg or more and meeting food standards. The production method provided by the invention has no adverse effect on the production performance of Beijing oil hens, can improve the health level of laying hens, improve the quality of eggs, is conducive to promoting the transformation and upgrading of laying hens with local characteristics and the functionalization of livestock and poultry products, and can be popularized and used.

Description

technical field [0001] The invention relates to the field of laying hen breeding, in particular to a selenium-enriched Peking oil chicken egg and a production method thereof. Background technique [0002] "Selenium" is an essential trace element in animals and humans, and is an important part of some antioxidant enzymes and selenoproteins, and plays an important role in life metabolism. In 1988, the Chinese Nutrition Society listed selenium as one of the 15 dietary nutrients that Chinese residents must take in every day. The dietary nutrient reference intake for Chinese residents (2013 edition) recommends 60 μg / d as the selenium supply standard for children over 7 years old, teenagers, adults and the elderly, and the intake of sub-health, cardiovascular patients, diabetes and other specific groups It is usually recommended to be above 100 μg. However, most of the residents in our country are in the state of selenium deficiency, the daily selenium intake is about 40 μg, and...
