Abstract
The present invention provides a preparation method of feed additive for control of avian coccidiosis. The preparation method comprises the following steps: (1) mixing essential oil products to obtain a semi-finished product; (2) mixing the semi-finished product 1 and medium chain aliphatic ester, homogenizing by a high-speed homogenizer, and emulsifying sufficiently to obtain a semi-finished product 2; (3) crushing the Macleaya cordata plants, sieing through a screen of 40 mesh to obtain a Macleaya cordata extract and silica particles and mixing to obtain a semi-finished product 3; and (4) mixing the semi-finished product 2 and the semi-finished product 3 in a spray manner by a spray tower to obtain the feed additive product after mixing. The method solves the volatile failure of volatile plant oil products, and explores the appropriate ratio of essential oils and Macleaya cordata plant. Compared to the prior art, the feed additive not only can effectively control avian coccidiosis, but also has the advantages of small addition amount, easy usage and security; therefore, the feed additive is worth promoting in the poultry industry.
Description
Technical field
The present invention relates to feed addictive preparation technology, be specifically related to a kind of feed addictive preparation method preventing and treating chicken coccidiasis.
Background technology
Along with China's poultry cultivation intensive degree is more and more higher, the danger coefficient that bird infects various epidemic disease also obviously rises, and wherein chicken coccidiasis is that one is the most common, endangers and very serious parasitic disease simultaneously.Chick after catching an illness, the death rate is up to 80%; Even if recover, the growth of chick also can be obstructed, and feedstuff-meat ratio increases, and causes serious financial consequences.The medicine preventing and treating global-worm illness of current use, three kinds can be divided into, one is polyether ionophoric antibiotics, as Hainanmycin, salinomycin, NARASIN, Tiamulin etc., though antibiotic thing effect is good, but have the problem of antibiotic residue and cross pollution, as the mixing of Monensin and Thailand wonderful mycin will cause poisoning; The second is chemical synthetic drug, as sulfamido, Robenidine, dimethiamine etc., this type of chemical synthetic drug inherently has very strong toxicity, as several anticoccidial chemical synthetic drug couplings, or easily produce poisoning with other antibiotic couplings, and due to drug-fast existence, the result of use of single chemical synthetic drug is not always very desirable.The third is Chinese herbal medicine, as sweet wormwood, Changshan, hairyvein agrimony, only dysentery grass etc.Although Chinese herbal medicine is environmental protection more, be used alone and there is drug effect slowly, the shortcomings such as addition is large, also counteracts that it further to the paces of marketing.
Plants essential oil is that the volatile aromatic oil mixture extracted by methods such as steam distillation, extrusion, solvent extractions, is had special odor, dissolve in organic solvent from the flower of plant, leaf, stem, root or fruit.Active component in essential oil has very strong surface-active tension force and fat-soluble, the cell membrane of pathogenic microorganism can be penetrated, its content is run off, stop Intramitochondrial breathing oxidizing process, finally cause pathogenic microorganism dead, essential oil can also stimulate the receptor on poultry alimentary canal mucous membrane simultaneously, activate digestion enzymatic activity, promotes digesting and assimilating of nutriment.
Macleaya cordata, Classification system Macleayacordata, belongs to Papaveraceae perennial vertical herbage plant.Be rich in the alkaloid components such as sanguinarine, opium alkali, Chelerythrine in macleaya cordata plant and seed, there is good antibacterial action.Test proves, macleaya cordata can stimulate T lymphocyte and bone-marrow-derived lymphocyte, reduces the level of serum lactic deaminase, improves the ratio of haemocyanin/hyperglobulinemia, reduces animal case fatality rate.
All there is both at home and abroad the hit and miss experiment about using plants essential oil and macleaya cordata as feed addictive, utilize the chemical agents such as Sha Linuo mycin, niclosamidum and the essential oil such as carveol, thymol material to be combined as patent publication No. CN101175532A, to parasite, especially antimalarial has good effect; Patent publication No. CN101171954A utilizes the essential oil materials such as firpene, thymol, eugenol, and saccharomycete, lactic acid bacteria mix, and also have good prevention and therapy effect to coccidia, clostridium disease; Patent publication No. 101972309A have studied the application of macleaya cordata extracts on economic animal veterinary drug, finds that it has good inhibitory action and killing effect to livestock and poultry encountered pathogenic bacteria; Patent publication No. CN104137949A have studied and directly uses the application of macleaya cordata plant on feed; Patent publication No. CN104247879A have studied other materials such as macleaya cordata, B B-complex, composite trace element and coordinates, the effect of preparation laying hen material.
Above-mentioned research, as prior art, the feed addictive preparation method of control chicken coccidiasis has following deficiency:
(1) reckon without the volatile feature losing drug effect of plants essential oil, above patent or directly employing liquid add; Or the adsorbent such as direct simple and practical active carbon, but essential oil belongs to volatile substances, and undressed essential oil product very easily loses drug effect;
(2) essential oil series products and probiotics mixing, reckon without the toxic and side effect of essential oil self to probiotics product;
(3) macleaya cordata plant or macleaya cordata extracts still belong to blank to the prevention effect of coccidia.
Summary of the invention
The present invention proposes a kind of feed addictive preparation method preventing and treating chicken coccidiasis, the present invention first by plants essential oil and macleaya cordata with the use of, and pass through research and probe, find the appropriate proportioning of plants essential oil and macleaya cordata, under this proportioning, this feed addictive has fabulous collaborative prevention effect to chicken coccidiasis.And plants essential oil and medium chain fatty acid ester are passed through homogenizer homogeneous by this method, plants essential oil is wrapped up by medium chain fatty acid ester, decreases the volatilization of plants essential oil, extends shelf life of products; Final products are pulverulent solids, compare with other liquid essential oil additives, and the interpolation that the present invention is more conducive to feed factory uses.
The present invention realizes particular by following technical scheme:
Prevent and treat a feed addictive preparation method for chicken coccidiasis, comprise the following steps:
(1) essential oil product is mixed, obtain semi-finished product 1;
(2) by after semi-finished product 1 and medium chain fatty acid ester mixing, by high-shear homogenizer homogeneous, make it fully emulsified, obtain semi-finished product 2;
(3) macleaya cordata plant was pulverized 40 eye mesh screens, the macleaya cordata extracts obtained afterwards and silica dioxide granule mixing, obtain semi-finished product 3.
(4) by semi-finished product 2 and semi-finished product 3 by spray tower spraying mixing, the product obtained after mixing i.e. feed addictive finished product for this reason.
Preferably, in step (1), essential oil product composition is cinnamic acid, Thymol, eugenol, carvacrol, peppermint oil and eucalyptus oil.
Preferably, in step (1), each composition of essential oil product is as follows by weight: cinnamic acid 30 ~ 40 parts; Thymol 10 ~ 20 parts; Eugenol 5 ~ 10 parts; Carvacrol 5 ~ 10 parts; Peppermint oil 1 ~ 3 part; Eucalyptus oil 30 ~ 40 parts.
