Description
Technical field
The present invention relates to field of feed additive technology, particularly relate to a kind of feed additive preventing and treating bird flu and system thereof
Preparation Method.
Background technology
Bird flu (Avian Influenza, AI) is caused by orthomyxoviridae family's Influenza Virus influenza A virus
Birds infects, and shows as the systemic infection of high incidence and high mortality, serious threat aviculture all over the world.Owing to fowl is flowed
The variation many, easy of Influenza Virus gene segment and restructuring, thus cause chemicals and vaccine to be all difficult to play the optimal anti-of them
Control effect.Under the ideological trend of current back to nature, food-safety problem is increasingly paid attention to by the world, the green preventing and treating of fowl diseases
Become main flow.
China's Chinese herbal medicine resource enriches, and Chinese herbal medicine has suppression virus replication, regulation immunologic function, stops virus to cause cell
The comprehensive effect such as pathological changes and easing pain and diminishing inflammation, and low toxic and side effects.Therefore, Chinese herbal medicine has wide for the preventing and treating of bird flu
Development prospect.
Summary of the invention
The technical problem to be solved is to provide a kind of effect and significantly prevents and treats the feed additive of bird flu.
Another technical problem to be solved by this invention is to provide the preparation side of the feed additive of this preventing and treating bird flu
Method.
For solve the problems referred to above, a kind of feed additive preventing and treating bird flu of the present invention, it is characterised in that: it by
The raw material composition of following weight portion: Folium Isatidis 30 ~ 60 parts, Herba Hyperici perforati 20 ~ 40 parts, the Radix Astragali 10 ~ 30 parts, 10 ~ 25 parts of Radix Glycyrrhizae.
The preparation method of a kind of feed additive preventing and treating bird flu as above, comprises the following steps:
(1) weigh by proportioning；
(2) after Folium Isatidis, Herba Hyperici perforati, the Radix Astragali, Radix Glycyrrhizae mix homogeneously, it is crushed to 40 ~ 120 mesh, obtains medical material powder；
(3) prepare fermented liquid:

~ 3.0 mg, cobaltous chloride 10 ~ 30mg, mix homogeneously, obtain fermented liquid；
(4) aspergillus niger seed culture fluid:
By 100 μ L Aspergillus niger suspension inoculations to potato dextrose agar, 30 DEG C of constant incubators are cultivated 3d,
A layer thickness to be grown uniform black spore；Then slant pore 3 is inoculated by every 150ml potato dextrose broth
Ring, shakes cultivation 24h at 30 DEG C with the speed of 130r/min, obtains aspergillus niger seed culture fluid；
(5) add fermented liquid described in 200 mL according to medical material powder described in every 100 g, and inoculate aspergillus niger seed described in 10 mL
Culture fluid, obtains mixed liquor；Described mixed liquor shakes cultivation 10 ~ 100 hours at 10 ~ 45 DEG C with the speed of 100 ~ 500 r/min,
Obtain the medicine after fermentation；
(6) after the medicine after described fermentation being dried 12 ~ 24h at a temperature of 35 ~ 65 DEG C, size-reduced, cross 100 mesh sieves and get final product.
Described step (4) middle potato dextrose agar refers to 200g peeling potatoes stripping and slicing, adds 1L distillation
Water, boils after 10 ~ 20min by filtered through gauze, and adds distilled water to 1L；It is subsequently adding 20g glucose and 20g agar, heating
Through 121 DEG C of sterilizing 20min and get final product after fusing.
Described step (4) middle potato dextrose broth refers to, by 200g peeling potatoes stripping and slicing, add 1L distilled water, boil
By filtered through gauze after boiling 10 ~ 20min, and add distilled water to 1L；It is subsequently adding 20g glucose, goes out through 121 DEG C after adding heat fusing
Bacterium 20min and get final product.
The present invention compared with prior art has the advantage that
1, the present invention selects the Radix Astragali, Radix Glycyrrhizae to join Folium Isatidis, Herba Hyperici perforati, mends and settles accounts conjunction, mends and does not help heat, is not just the most hindering；And wherein
Folium Isatidis, Herba Hyperici perforati primary efficacy be antiviral, antibacterial, heat-clearing and toxic substances removing, diuresis, profit larynx；The Radix Astragali, Radix Glycyrrhizae mainly strengthen machine
Body resistance, promotion immunity, promotion antibody tormation and the raising of resistance against diseases, therefore, this Chinese medicine composition selects medical material reasonable.
2, the present invention is produced by aspergillus niger cellulolytic enzyme, hemicellulose catabolic enzyme destroy plant amedica cell wall knot
Structure, such that it is able to increase substantially active constituent content and the animal utilization ratio to effective ingredient in medical material.Through efficient liquid phase
Chromatograph detection shows, its principle active component 4 (3) H quinazolone, hypericin, astragalus polysaccharides and the content of liquirtin after fermentation
It is respectively increased 12%, 30%, 8.2% and 5.8%.
3, the present invention is notable through test preventing and treating bird flu effect.
Test method: take 2 week old chickling 200,100 feeding normal diets；100 feedings contain embodiment 1 to be prepared
Chinese herbal medicine additive feedstuff.To two groups of chickling intramuscular injection bird flu (AV) after 24 hours, mortality rate (ginseng in recording 2 weeks
It is shown in Table 1).
Table 1
Result of the test shows, the chickling mortality rate of feeding Chinese medicine feed additive is substantially less than matched group.
4, the present invention can prevent and treat bird flu, can improve again the immunity of animal, the most also has that side effect is little, cost
Low, technique is simple, it is easy to the features such as industrialization.
