Embodiment 1
[0027] Feed for laying hens: 55 parts of corn, 20 parts of soybean meal, 5 parts of bran, 5 parts of sorghum, 5 parts of fish meal, 3 parts of bone meal, 3 parts of oyster powder, 1 part of amino acid and 0.2 part of table salt. Sodium selenite, zinc lactate and ferrous lactate were added to the layer feed of the above formula, so that the concentrations of selenium, zinc and iron were 8 mg / kg, zinc 500 mg / kg and iron 1000 mg / kg, respectively.
Embodiment 2
[0029] Feed for laying hens: 58 parts of corn, 16 parts of soybean meal, 4 parts of bran, 4 parts of sorghum, 8 parts of fish meal, 4 parts of bone meal, 4 parts of oyster powder, 1.5 parts of amino acid and 0.1 part of table salt. Sodium selenite, zinc lactate and ferrous lactate were added to the layer feed of the above formula, so that the concentrations of selenium, zinc and iron were 10 mg / kg, 400 mg / kg zinc and 1200 mg / kg iron, respectively.
Embodiment 3
[0031] Feed for laying hens: 50 parts of corn, 25 parts of soybean meal, 8 parts of bran, 4 parts of sorghum, 6 parts of fish meal, 3 parts of bone meal, 2 parts of oyster powder, 1.5 parts of amino acid and 0.2 part of table salt. Sodium selenite, zinc lactate and ferrous lactate were added to the layer feed of the above formula, so that the concentrations of selenium, zinc and iron were 6 mg / kg, 600 mg / kg zinc and 800 mg / kg iron, respectively.

Abstract
The invention discloses chicken feed rich in selenium, zinc and iron as well as a production method of eggs rich in selenium, zinc and iron. Layer feed rich in selenium, zinc and iron is prepared, layers are fed with the feed one week before the egg production period, and the eggs rich in selenium, zinc and iron can be produced. The contents of selenium, zinc and iron in the eggs are 1.16-1.57 mg / kg, 12.1-14.8 mg / kg and 20.2-25.3 mg / kg respectively, which are 10.4, 3.3 and 2.0 times higher than those of selenium, zinc and iron in ordinary eggs (in contrast), and the eggs can supplement the human body with required selenium, zinc and iron microelements simultaneously after being eaten and have better promotion effects on improvement of human immunity and intelligence development of children. The eggs have yellow color and good taste. The technology is simple, low in cost and easy to promote, the products are safe and healthy, and the economic benefits of layer breeding can be significantly increased.
Description
technical field [0001] The technology relates to a chicken feed and an egg-laying feeding method, in particular to a chicken feed enriched in selenium, zinc and iron and a production method of eggs enriched in selenium, zinc and iron at the same time. Background technique [0002] Selenium is one of the essential trace elements in human life activities. It is an antioxidant in the human body, can improve human immunity, and has the functions of preventing diabetes, cataracts, cardiovascular and cerebrovascular diseases, Keshan disease, Kaschin-Beck disease, arthritis, detoxification, and detoxification. , and protect the liver and other functions. Human cancer, cardiovascular and cerebrovascular diseases, children's mental retardation, senile dementia and other 42 diseases may all be related to selenium deficiency. Normal people need to supplement dietary selenium 50-250 µg per day, the maximum safe intake is 400 µg, and the limit toxic dose is 800 µg. my country is a coun...
