Abstract
The invention discloses a kind of piglet calm the nerves increase exempt from growth-promoting feedstuff additive, comprising: the red sage root, polygala root, grass-leaved sweetflag, L-thiamine and nano level modified montmorillonite. The present invention also provides preparation method and application's method of above-mentioned feed addictive. It is that primary raw material prepares feed addictive by multiple Chinese herbal medicine and L-thiamine that the present invention adopts, and realizes the coordination linkage of multiple Chinese herbal medicine and L-thiamine, can make piglet daily ingestion amount, daily gain significantly improve, and material anharmonic ratio and Scours index significantly decline; Immunologic function (comprising Immune Organs Index, periphery blood T lymphocyte conversion ratio, immunoglobulin content, IL activity index) significantly strengthens; Anti-oxidation function (comprising serum glutathione peroxidase, superoxide dismutase and catalase activity) significantly strengthens, and also has obvious anti-stress effect.
Description
Technical field
The invention belongs to field of feed additive technology, specifically relate to a kind of piglet growth that improvesFeed addictive, the preparation side of can, improve immunity, improve oxidation resistance and strengthen antistress functionMethod and application thereof.
Background technology
Along with developing rapidly and the continuous expansion of the scale of raising pigs of aquaculture, in modernized pig raising is producedProgressively popularize the early weaned technology of piglet. Early-weaned piglets is due to growth, physiology spyPoint and environment, nutrition, stress wait the impact of factor, there will be a series of stress reaction, mainly tableNow growth retardation, premunition weak, be afraid of cold and suffer from diarrhoea, finally cause piglet survival ratio low, give cultivationVery large economic loss has been brought in field (family), therefore, needs suitable product to solve this in productionA large difficult problem.
Undeniable, in the past few decades, antibiotic is being prevented and treated animal disease as feed addictiveDisease, improves breeding performonce fo animals aspect and has played huge effect. But, antibiotics additiveLong-term use, causes many adverse consequences, makes germ produce drug resistance, and then in livestock productsThe residual health that has influence on people. For this reason, developed country is used and has carried out strict restriction antibiotic,Within 2006, European Union forbids fodder antibiotics comprehensively. The new feed addictive management rules of China are also to antibiosisStrict regulations have been made in the use of element additive.
Therefore, the growth promotion of the safety of development of new, increase immunity, anti-stress with oxidation resistant feedAdditive is to overcome in animal production process, to occur hypoimmunity, improve animal product quality safetyAnd overcome the optimal path that stress wait problem. For example publication number is that 103504138A discloses oneAdditive for feed for piglets, is made up of the material combination of following weight proportioning: every kilogram of pig starter feed addsAgent is containing amino acid chelate iron 50-200g, zinc-amino acid chelate 50-100g, quinocetone 50-100g, dysenteryThe clean 50-100g of bacterium, all the other are carrier. This feed addictive has prevention dysentery, promotes the merit of growthEnergy. But above-mentioned feed addictive mainly adopts western medicine composition, easily cause medicament residue. Moving at presentThing nutritionist carrys out substitute antibiotics seeking natural active matter. Mainly research and develop prebiotic both at home and abroadThe multiple additives such as element, oligosaccharides, plant extracts, Chinese herbal medicine, to growth promotion, improve immunity,Anti-stress having certain effect, but effect does not have breakthrough progress.
We,, in having accepted multinomial provinces and cities scientific research project, are devoted to the research of theanine always,It can be produced by extraction in tealeaves, microorganism fermentation and chemical synthesis, and cost is controlled, ringPacking pressure is little, does not have the problem of resource shortage. The theanine aqueous solution is subacidity, have sweet taste andFresh refreshing taste. Except being proportionate with tea flavour, also have promote cerebral neural growth, antitumor,Hypertensive tranquilizing, the gentle solution of antianxiety tired, anti-ly stress, be helped smoking cessation, promotes growth, raising machineThe effects such as body immunity, can be used as novel antidepressant and green hypnotic etc. (U.S. of a lot of developed countryState, Japan, European Union etc.) it is listed in to medicine, food additives. And China only using its asNew medicine product are used, and not yet list in food additives and food enrichment. We pass throughThe discovery of animal experiment Primary Study, theanine can effectively improve animal immune ability and resist stress energyPower, and promote growth of animal is that a kind of immunity of novel green safety and environmental protection is anti-stress additive. KnotClose our research as feed addictive at Chinese herbal medicine in early days, comprise that improving the calm Chinese medicine of immunity joinsSide and process technology (cellular level pulverizing technology), can be used as supporting technology and further investigate,Form brand-new growth promotion, increase immunity, anti-stress and antioxidant, be expected to solve upper in producingState a difficult problem.
Summary of the invention
The invention provides a kind of piglet and calm the nerves to increase and exempt from growth-promoting feedstuff additive, this additive adopts multipleChinese herbal medicine and theanine are that primary raw material prepares, can significantly improve piglet growth performance, immunity,Anti-oxidant and antistress function.
The present invention also provides a kind of above-mentioned piglet to calm the nerves to increase and has exempted from the preparation method of growth-promoting feedstuff additive,This preparation method's technique is simple, can be suitable for suitability for industrialized production.
The present invention also provides a kind of above-mentioned piglet to calm the nerves to increase and has exempted from the application process of growth-promoting feedstuff additive,In application process, can make piglet daily ingestion amount, daily gain significantly improve, Scours index and material anharmonic ratio are aobviousWork declines; Piglet immunological, anti-oxidant and anti-stress ability significantly strengthen.
A kind of piglet is calmed the nerves to increase and exempts from growth-promoting feedstuff additive, comprising: the red sage root, polygala root, grass-leaved sweetflag, L-Theanine and auxiliary material; Described auxiliary material can adopt nano level modified montmorillonite.
As preferably, to calculate according to percentage by weight, described piglet is calmed the nerves to increase and exempts from growth-promoting feedstuff interpolationAgent comprises:
As further preferably, to calculate according to percentage by weight, described piglet is calmed the nerves to increase and exempts from short long raisingFeed additives comprises:
In above-mentioned each traditional Chinese medicinal components:
