Description
Technical field
What [0001] the present invention relates to is the feed addictive in agriculturist's poultry raising field, specifically a kind of feed addictive of layer chicken that contains compound selenium element.
Background technology
The selenium element produces in vivo regulates immunity and antitumaous effect, obtained social recognition, and the people can not directly eat selenate, because directly edible selenate is to the toxic elements in human body evil.Someone adds selenate in the chicken feed, after using through chicken feed, transform and enrichment through absorbing, because the selenium element in chicken internal deposition and enrichment, also contains the selenium element in the egg of being produced.Though in egg, contained the selenium element, selenate is to the harmful effect of having grown of chicken, thereby reduced the general level of the health of chicken, shortened the life-span, and the easy infection disease, even bears soft-preserved egg, and egg production reduces.
Through network retrieval, have the explanation of a data following: selenium be between metal and nonmetal between trace element, chemical property is similar with sulphur.Modern medicine study shows: selenium can be removed " rubbish " in the body at human body, constitutes effective protection system of a lipid peroxidation, and is collaborative with preventing that " rubbish " in the body is to the attack of healthy cell with vitamin E; Improve erythrocytic oxygen carrying capacity; Improve the human immunological competence; Can play and detoxify and the toxin expelling effect can carcinogenic harmful metal ion in the body directly getting rid of externally, be described as natural antidote, resist environmental pollution during the struggle, play an important role the mankind; Symptoms such as dementia, feeblemindedness and the skeleton development that can prevent thyroid hormone secretion hypofunction or disorder to cause is bad; Protect organum visuale's the function that perfects; Protect cardiovascular and myocardium health; When numerous diseases such as current cancer do not have specific drug, prevent multiple disease to seem particularly important through absorbing enough selenium.Disclose according to " People's Republic of China's localized disease and environmental factor atlas ": North China, northeast, East China, south China, the Delta of the Pearl River, most of areas such as Yangtze River Delta all belong to and lack the selenium area, lack selenium population and reach 700,000,000.China trace element is longer than if wood is pointed out with the healthy director of association: " China is scarce selenium big country, and it is to be related to the healthy major issue of hundreds of millions of Chinese people that human body is mended selenium, should popularize relevant knowledge; start to develop and produce selenium-enriched food; and the large-scale promotion selenium-enriched food, science is mended selenium, and is very urgent ".
Nature selenium element is just few, organic selenium just still less, and inorganic selenium has severe toxicity, the people can not directly eat, and in view of the important function of organic selenium at human body, how to be converted into the focus that organic selenium has just become various countries' researchs to inorganic selenium.The scientific research personnel of China has carried out bold trial in this respect, has obtained huge achievement.
Let the simplest way of the rich selenium of egg be exactly directly to eat the inorganic salts sodium selenite to chicken---or mix with water in, or mix in feed.Begin to eat the inorganic salts sodium selenite from chicken, the organic selenium enriching quantity in the egg progressively promotes, and reaches peak value in general 15 days.The shortcoming of feeding chicken production Se-enriched egg with the inorganic salts sodium selenite is the injury of inorganic salts sodium selenite to chicken, eats the inorganic salts sodium selenite to chicken for a long time, and chicken egg production can occur and descend; Very person's total crop failure; The chicken body falls hair, and is One's spirits are drooping depressed, and chicken is dead in serious causing.Health from chicken is considered, directly feeds chicken with the inorganic salts sodium selenite and produces Se-enriched egg, and must be intermittent, so just caused the instability of the rich selenium amount of egg, can not form stable commodity.
In order to produce the egg product of rich stable selenium content; To the shortcoming of directly feeding chicken with the inorganic salts sodium selenite; Someone is used for alfalfa planting to inorganic salts sodium selenite as fertilizer sources, just is converted into organic selenium to the inorganic salts sodium selenite through clover, lets chicken eat clover again.This method can be produced the stable egg product of Se content, and shortcoming is that inorganic salts sodium selenite as fertilizer sources in use produces harm to the people easily, simultaneously there is harm to a certain degree in environment.
What the production Se-enriched egg was comparatively advanced now is: be converted into organic selenium to the inorganic salts sodium selenite through zymotechnique with yeast, let chicken eat the yeast of this rich selenium then.Utilize the harm of inorganic salts sodium selenite to chicken, human and environment though the method for this production Se-enriched egg has solved, because of its complex process, investment is big, is not suitable for the ordinary people development.
Because the cheapness property of inorganic salts sodium selenite; Someone still directly lets chicken feed use the inorganic salts sodium selenite in order to produce Se-enriched egg, and different is to let chicken eat certain Chinese medicine simultaneously; With of the injury of Chinese medicine antagonism inorganic selenium, thereby produce the stable egg product of Se content to chicken.Related data shows the people and has obtained national patent in this respect.
The above method all is simple technique of enriched selenium.Modern Chinese medicine research shows that a lot of Chinese medicines also also have abundant organic selenium, and the rich selenium Chinese medicine of generally acknowledging now has the Radix Astragali, honeysuckle, rabbit silk etc.Modern Chinese medicine research shows that also the organic selenium in the Chinese medicine is to have synergistic material one to work with the material identical with the selenium effect and with selenium.Can the organic selenium in the Chinese medicine and with the selenium effect roughly the same, synergistic material enrichment in the middle of egg, make the health care of egg more powerful.Principle according to the restriction or checking relation in five elements of traditional Chinese medical science mutual generation of five phases; Reasonable formula; Successfully extracted in the Chinese medicine selenium and with the selenium effect roughly the same, synergistic material, the egg of producing is the test of spectrum Buddhist nun test center through Beijing, Se content reaches 32ug/100g (national regulation Se-enriched egg standard: 20ug/100g < selenium < 50ug/>100g); Further detection is also underway, and next step object of experiment is to make the selenium content of egg near 50ug/100g.
How to produce Se-enriched egg, selenium is one of important trace element of needed by human, have anti-ageing, anti-oxidant, improve multiple effect such as immune function of human body.Edible Se-enriched egg is to replenish a not enough optimal path of human body selenium.According to research, the selenium in the Se-enriched egg is organic selenium chelate that inorganic selenium combines with amino acid, lipoprotein, and is non-stimulated to intestines and stomach, and advantages of easy digesting absorbs, and is without any side effects.
Through patent retrieval, one piece of document is arranged, be a kind of application for a patent for invention.The content of its specification digest is: the present invention relates to a kind of production method that reduces the Se-enriched egg of lead concentration of children.Comprising that (1) adds the Se-enriched feedstuff that contains the selenium element in the chicken feed to according to 0.1-15% mixes, and it is subsequent use to process special-purpose chicken feed; (2) special-purpose chicken feed was pressed normal amount feeding chicken 3-5 days, the selenium element of 6-10 days adding 0.001-0.01 parts in special feed; In special feed, added the selenium element of 0.001-0.005 part in (3) 10-15 days, the feeding laying hen is collected the egg censorship and detects, and the egg Se content is controlled at 2.0-2.5PPm.The egg that the present invention produced is except that the selenium content height; Beneficial element calcium, zinc content increase; Harmful element is plumbous, mercury content reduces, and proves the effect that the Se-enriched egg that edible the present invention produces has obvious reduction lead concentration of children through the clinical observation to 200 3-6 year children.
Through as above document and explanation proof,, how to obtain stable and the adjustable method of content is held and waited to study though Se-enriched egg has a lot of benefits to human body.
Summary of the invention
Chicken is not produced harm in order to obtain to contain the selenium egg, the present invention proposes a kind of feed addictive of layer chicken that contains compound selenium element.This feed mixes the selenium forage additive that contains of composition in proportion with manganese sulfate, zinc sulfate and sodium selenite and biology enzyme, is added in the egg feedstuff, solves feed and feeds behind the chicken technical problem that contains the selenium egg by predetermined Se content production and chicken do not produced harm.
