Problems solved by technology

[0005] At present, there are many ways to produce selenium-enriched eggs in China. Most of them use excessive selenium (sodium selenite) in chicken feed to increase the selenium content in chicken feed. After feeding, the selenium content in eggs can be increased. purpose, but sodium selenite itself is a more toxic substance, and its disadvantages are that the content of selenium is unstable, the bioavailability is very low, the deposition of selenium in eggs is low, the dosage is difficult to control, and it is easy to add excessive amounts. cause egg toxicity
Therefore, it is difficult to produce selenium-enriched eggs by simply increasing the content of selenium in actual production.

Embodiment 1

[0035] Preparation of selenium-enriched feed

[0036] The composition of the selenium-enriched feed containing selenium: 30g black beans or black fungus, 5g mussels or seaweed, 15g each of astragalus and medlar.

[0037] The preparation method is to soak the astragalus medicinal material and wolfberry fruit in water for 60 minutes. Then carry out extraction, sink in water to prepare the traditional Chinese medicine extract, then mix with other raw materials according to the above ratio, add water and stir evenly, and set aside.

[0038] Mix 0.1% selenium-enriched feed with selenium chicken feed evenly to make special chicken feed for later use;

[0039] (2) After feeding the special feed for chickens in normal amount for 5 days, add 0.01 part of selenium element (in terms of special feed total weight) in the special feed total weight on the 10th day;

[0040] (3) On the 15th day, add 0.005 parts of selenium (in terms of the total weight of the special feed) to the special fe...

Embodiment 2

[0044] Preparation of selenium-enriched feed

[0045] The composition of the selenium-enriched feed containing selenium: 100g each of black beans and black fungus, 15g each of mussels and seaweed, 65g each of astragalus and medlar. The preparation method is to extract the astragalus medicinal material and wolfberry fruit with water, sink in water to obtain the traditional Chinese medicine extract, then mix it with other raw materials according to the above ratio, add water and stir evenly, and set aside.

[0046] (1) 5% selenium-enriched feed containing selenium is mixed evenly with rice chicken feed to make special chicken feed for subsequent use;

[0047] (2) After feeding the special feed for chickens in a normal amount for 5 days, add 0.08 parts of selenium element (in terms of special feed total weight) in the special feed on the 10th day;

[0048] (3) On the 15th day, add 0.01 part of selenium element (in terms of the total weight of the special feed) in the special fee...

Embodiment 3

[0051] A production method of selenium-enriched eggs that reduces children's blood lead concentration:

[0052] (1) Add the selenium-enriched feed containing selenium to the corn chicken feed according to 10% (weight percentage) and stir and mix evenly to make special chicken feed for subsequent use;

[0053](2) Feed the special-purpose chicken feed to chickens by normal amount for 5 days, and add 0.005 parts of selenium special-purpose feed (in special feed total weight) in the special-purpose feed on the 10th day;

[0054] (3) On the 15th day, add 0.005 parts of selenium element (in terms of special feed total weight) in the special feed, feed laying hens, collect eggs for inspection and detection, and the selenium content of eggs is 2.0PPM (method is the same as embodiment 1);

[0055] (4) Continuous feeding for 30-40 days, intermittent 10-15 days, and so on.

Abstract

The invention relates to a production method of an egg containing rich selenium, which can be used for reducing blood lead level of children. The method of the invention comprises the steps as follows: (1) the material containing rich selenium is added into chicken feed with a ratio of 0.1 percent to 15 percent and is stirred and mixed evenly, thus obtaining special chicken feed for reserving; (2) feeding chicken with the special chicken feed for 3-5 days according to normal feeding amount and then adding 0.001-0.01 portions of selenium element into the chicken feed for feeding in the sixth-tenth days; (3) adding 0.001-0.005 portions of selenium element into the chicken feed for feeding layer chickens in the 10th-15th days and collecting eggs for testing and controlling the content of selenium element in 2.0-2.5PPM. Besides containing rich selenium, the eggs produced according to the method of the invention contain higher beneficial elements of calcium and zinc and less harmful elements of lead and mercury. By clinically observing to more than 200 children of 3-6 years old, the produced egg in the method of the invention can effectively reduce blood lead level of children.

Description

technical field [0001] The invention belongs to the technical field of feed production and relates to a method for producing selenium-enriched eggs that can reduce the blood lead concentration of children. Background technique [0002] Selenium is an essential trace element for the human body. It has a variety of physiological functions, especially the obvious detoxification effect on toxic heavy metals. Selenium has a strong affinity with heavy metals and can combine with heavy metals in the body such as lead, mercury, cadmium, etc. to form Metal-selenoprotein complexes, thereby detoxifying and promoting the excretion of metals from the body. [0003] Lead is a neurotoxic substance. Low concentrations of lead can damage many functions of the nervous system, but mainly affect children's intellectual development. The blood lead content of children is closely related to the IQ (IQ). When the blood lead level is 300-400ug / L, the IQ will drop by 4-6 points, and there will be no...
