Abstract

The invention relates to a feed which can improve immunity of livestock and is rich in organic selenium and organic zinc. The organic selenium is selenium gluconate, and the organic zinc is zinc gluconate. Selenium gluconate, zinc gluconate and chitosan oligosaccharide are uniformly mixed in a weight ratio of 1:10:100 and are combined into a feed additive. According to different livestock species, the feed additive is mixed into a basal feed in a corresponding ratio, and a weight ratio of the blended feed additive to the basal feed is 0.01-0.1%, wherein the basal feed refers to all the feeds used for farming the livestock such as chickens, ducks and pigs. The feed provided by the invention overcomes the defects that toxicity is high, absorption rate is low and palatability is poor as an inorganic selenium source sodium selenite and zinc sulphate are numerously added in the original technical scheme; meanwhile, chitosan oligosaccharide is added in compatibility, immunity of the livestock can be enhanced, and absorption of selenium and zinc elements can be promoted; and besides, cost is moderate, so that the feed provided by the invention is applicable to industrial farming.

Description

A kind of improve the immunity of livestock feedstuff rich in organic selenium and organic zinc

Technical field

The invention belongs to animal and fowl fodder technical field, relate in particular to and a kind of improve the immunity of livestock feedstuff rich in organic selenium and organic zinc。

Background technology

Selenium is not only the trace element of needed by human, is also the indispensable biological element of animal and plant growth simultaneously。Human body lacks selenium can directly cause the generation of more than the 40 kind of relevant diseases such as cancer, hypertension, cardiovascular and cerebrovascular disease, diabetes, hepatitis。Shi Que selenium big country of China, having 72% soil is Que Xi district in various degree, the population selenium Deficiency of Intake of about 2/3。The standard that international selenium association is recommended is that to take the photograph selenium amount per capita be 60 μ g/d, and China adult takes the photograph selenium amount and is only about 30 μ g/d, and therefore exploitation selenium supplement product is healthy significant to the whole people。Animal proteinum is the important sources of needed by human body albumen, has absorbance height compared with vegetable protein, the advantage that anaphylaxis is low。Therefore, develop the feedstuff rich in selenium element and be used for cultivating, thus developing the products such as selenium-rich meat, egg, milk is the effective means realizing human body selenium supplement, be also to ensure that livestock birds health grows simultaneously, ensure that aquaculture obtains the important measures of good economic benefits。

At present about producing Se-enriched feedstuff technically mainly through two kinds of methods realizations: 1) inorganic interpolation。Most interpolations are all sodium selenite。But, this mode is due to the shortcoming that sodium selenite toxicity is high and safety is low, and developed country prohibitted the use of in the nineties in last century；2) organic interpolation。One is to add in feedstuff after inorganic selenium being converted into organic form by the plantation of plant selenium-rich；Another kind obtains organic form selenium by microbial transformations such as fermentations and adds in feedstuff。The common shortcoming of both bioconversion be industry chain length, relatively costly, be difficult to form economic benefit；It addition, two kinds of bioconversion modes convert composition the unknown, conversion process is uncontrollable, and conversion results is unpredictable, it is difficult to meet the requirement that industrial standardization produces。Therefore, finding desirable organic selenium source is the key of exploitation organic selenium-rich feedstuff, and it should possess following condition: good water solubility, absorbance height, safety height, definite ingredients, dosage are accurate, moderate cost。

Zinc is another required trace element of human body, various metabolic activities in wide participation body。The symptoms such as zinc deficiency can cause malnutrition, growth retardation, the hypophrenia, aging, anorexia and dermatosis。The nutrition recommended amounts of China's adult's zinc every day is 15-20 milligram, but actual intake differs from it by very remote。Zinc especially growth promoter and intelligent development to youngsters and children is most important, is related to the happiness in all one's life。A lot of the child of China's zinc deficiency, child especially likes edible animal proteins food, therefore, the rich organic zinc animal and fowl fodder of exploitation, produce zinc supplement food, equally that national health is most important。

For aquaculture, reducing sufferer and occur, it is most important for guaranteeing safe production。Therefore, improve immunity of livestock, reduce disease and occur aquaculture is meant a great。Oligochitosan is a kind of very strong raising animal body immunity material being found in recent years, there is advantage nontoxic, without thermal source, nothing variation, microbiota metabolic activity in animal intestinal can be regulated, increase gastrointestinal motility, Selective activation propagation probiotics growth, obstruction growth of pathogenic bacteria is bred, thus improving poultry resistance against diseases。In addition, it is important that oligochitosan can also promote that selenium, zinc element are in the absorption of small intestinal, improve its bioavailability。

Having been reported that about the patent rich in selenium zinc feed, it is contemplated that the factor such as cost and production technology, most is all inorganic constituents rich in the selenium zinc composition in zinc selenium feedstuff, selenium element many employings sodium selenite, zinc element many employings zinc sulfate more。The mode of this interpolation has the drawback that: 1, for sodium selenite, toxicity is bigger, and safety limit narrow easily causes toxic and side effects, even if some inorganic selenium being converted into organic selenium form by the body bioconversion of poultry, but convert not thorough, livestock meat egg milk still has more inorganic selenium, there is potential safety hazard；2, for zinc sulfate, after dubbed feed, palatability is poor；It addition, absorbance is low, it is necessary to some albumen, polysaccharose substance assistance increase its absorbance。

Summary of the invention

The present invention is directed to the problems referred to above, selenium-rich and zinc-rich meat, eggs and milk product for production safety nutrition, the inorganic selenium source of sodium selenite is replaced using the Glucose acid selenium of inventor's patented technology production as organic selenium source, the inorganic zinc source of zinc sulfate is replaced using zinc gluconate as organic selenium source, original technology use the toxicity caused by inorganic constituents big thus solving, absorbance is low, the defect of palatability difference, and glucose can promote the absorption in vivo of selenium element and zinc element and conversion as glycosyl, additionally, by two kinds of materials and the biological polyoses oligochitosan compatibility with raising immunity, not only can improve the premunition of poultry, the absorption of selenium zinc and other mineral element can be promoted again, it may be said that, after these three material compatibility, not only each played a role but also effect had been worked in coordination with, and moderate cost, it is suitable for industrialized production。

The present invention adopts following technical method to realize:

A kind of immunity of livestock that improves refers to Glucose acid selenium rich in the organic selenium in the feedstuff of organic selenium and organic zinc, and organic zinc refers to zinc gluconate。Preparing of feedstuff is as follows: first, the preparation of feed additive。It is that 1: 10: 100 mix homogeneously hybrid combination becomes feed additive by weight by Fructus Vitis viniferae acid selenium, zinc gluconate, oligochitosan three。Secondly, the preparation of feedstuff。In corresponding ratio, above-mentioned feed additive is blended in normal feedstuff according to different poultry kinds, the feed additive prepared and normal feedstuff are 0.01%～0.1% proportioning by weight, wherein, normal feedstuff refers to all feedstuffs for livestock and poultry cultivations such as chicken and duck pigs。Raw material Fructus Vitis viniferae acid selenium used in feed additive is prepared with reference to the present inventor's patent CN201510615403 method。
