Technical field
The invention belongs to field of feed additive technology, be specifically related to a kind of poultry fodder additive, also relate to a kind of preparation method of poultry fodder additive simultaneously.
Background technology
In recent years, people's living standard improved constantly, and also got more and more to the demand of livestock products.But because raiser hankers after the output pursuing livestock products usually, thus have ignored the problem of Safety of Livestock Products ' Quality, especially veterinary drug and the medicated premix residue problem in livestock products, causes food-safety problem to take place frequently.Therefore, reduce residual, the exploitation nuisanceless green livestock products of chemical substance in animal product and become the focus of people's growing interest and research.
Green feed additive not only can to solve in long-standing problem China animal husbandry development chemical synthetic drug in cultured product and remain excessive problem, can also solve the problem owing to adding the pathogenic bacteria resistance to drugs that antibiotic causes, therefore become the focus of research gradually.
Summary of the invention
The object of this invention is to provide a kind of poultry fodder additive, solve existing feed addictive and easily cause chemical synthetic drug in cultured product to remain the problem exceeding standard and add the pathogenic bacteria resistance to drugs that antibiotic causes.
Second object of the present invention is to provide a kind of preparation method of poultry fodder additive.
In order to realize above object, the technical solution adopted in the present invention is: a kind of poultry fodder additive, is made up of the component of following parts by weight: Astragalus Root P.E 20 ~ 50 parts, licorice 10 ~ 40 parts, Fructooligosaccharides 20 ~ 40 parts.
Described Astragalus Root P.E is prepared by following methods: get Milkvetch Root, adds boiling in distilled water and extracts 2 ~ 3 times, each 1 ~ 1.5h, after filtration, filtrate is condensed into ointment, the quality of ointment is 0.5 ~ 2 times of Milkvetch Root quality, ointment is carried out spraying dry, obtains Astragalus Root P.E.
The consumption of described distilled water is 6 ~ 8 times of Milkvetch Root quality.
Described licorice is prepared by following methods: extracting liquorice medicinal material, extracts 2 ~ 3 times, each 1 ~ 2h with ethanol water, after filtration, filtrate is condensed into ointment, the quality of ointment is 0.5 ~ 1 times of licorice medicinal materials quality, by ointment spraying dry, obtains licorice.
In described ethanol water, the mass fraction of ethanol is 30% ~ 60%; The consumption of ethanol water is 6 ~ 10 times of licorice medicinal materials quality.
A preparation method for poultry fodder additive, comprises the following steps:
1) preparation of Astragalus Root P.E: get Milkvetch Root, adds boiling in distilled water and extracts 2 ~ 3 times, each 1 ~ 1.5h, after filtration, filtrate is condensed into ointment, the quality of ointment is 0.5 ~ 2 times of Milkvetch Root quality, ointment is carried out spraying dry, obtains Astragalus Root P.E;
2) preparation of licorice: extracting liquorice medicinal material, extract 2 ~ 3 times with ethanol water, each 1 ~ 2h, is condensed into ointment by filtrate after filtration, and the quality of ointment is 0.5 ~ 1 times of licorice medicinal materials quality, by ointment spraying dry, obtains licorice;
3), after the licorice of the Astragalus Root P.E of 20 ~ 50 weight portions, 10 ~ 40 weight portions, the Fructooligosaccharides of 20 ~ 40 weight portions being mixed, cross 50 ~ 60 eye mesh screens, gained fine powder is described poultry fodder additive.
The consumption of distilled water described in step 1) is 6 ~ 8 times of Milkvetch Root quality.
Step 2) described in ethanol water the mass fraction of ethanol be 30% ~ 60%; The consumption of ethanol water is 6 ~ 10 times of licorice medicinal materials quality.
Poultry fodder additive of the present invention, during use, is mixed in bird feed according to the mass fraction of 1% ~ 5%.
The Radix Astragali, has effect that invigorating qi for consolidating superficies, arrest sweating are admittedly de-, hold in the palm sore myogenic, inducing diuresis for removing edema, and containing plurality of active ingredients such as polysaccharide, saponin, flavones, amino acid in its extract, these active components all have enhancing antibody to generate and immunoreactive effect.Wherein astragalus polyose has the utilization improving nutriment, the function promoting growth of animal, the multiple nutrients materials such as its embedded amine groups acid, vitamin, trace element; Containing UGF (UGF); Astragalus Root P.E can significantly improve the speed of growth of livestock and poultry as feed addictive, promotes Abwehrkraft des Koepers, improves meat, eggs and milk quality and output.
Radix Glycyrrhizae, has and invigorates the spleen and benefits qi, clearing heat and detoxicating, expelling phlegm and arresting coughing, relieving spasm to stop pain, effect of coordinating the drug actions of a prescription.Containing glycyrrhizin, glycyrrhizic acid in licorice, liquiritin, flavonoids of Glycyrrhiza, rear curtain, than wingceltis element, formoononetin, Quercetin etc., are wherein main active with glycyrrhizic acid.Licorice has removing toxic substances, anti-inflammatory, antibechic, antiulcer, the effect such as antibacterial, has the effect of develop immunitypty simultaneously.
Fructooligosaccharides is the general name of the one group of compound sugar formed in conjunction with several D-Fructose base with β-1,2-glycosidic bond on sucrose molecule, have relax bowel, the effect such as fire, develop immunitypty falls in toxin expelling; These effects are by promoting the propagation of intestinal beneficial bacterium and then regulating microflora balance in animal intestinal to realize.
Poultry fodder additive of the present invention, by Astragalus Root P.E, licorice, Fructooligosaccharides is composite forms, and is green feed additive, the feature have nontoxic, noresidue, having no side effect; By regulating the growth performance of bird intestinal microenvironment and then raising bird, strengthening the immunity of bird, improving bird resistance against diseases; Solve the problem that chemical synthetic drug in cultured product remains excessive problem and adds the pathogenic bacteria resistance to drugs that antibiotic causes.
The preparation method of poultry fodder additive of the present invention, technique is simple, easy to operate, is applicable to large-scale industrial production.
