Technical field
The present invention relates to the field of Chinese medicines, be specifically related to snorting Chinese medicine composition for the treatment of pig and preparation method thereof.
Background technology
Swine enzootic pneumonia or mycoplasma pneumoniae of swine, also known as mycoplasma hyopneumoniae, are a kind of chronic respiratory infectious disease of pig.The main clinic symptoms of primary disease is cough and asthma, and pathological change position is mainly positioned at thoracic cavity.Lungs are major organs of pathological changes.Acute case is based on pulmonary edema and emphysema; Subacute and chronic cases is shown in pulmonary's " Macrobrachium nipponensis " sample consolidation.The speed of growth of morbidity pig is slow, and efficiency of feed utilization is low, and the feeding for fattening phase extends.
This disease is also called mycoplasmal pneumonia of swine and epidemic swine pneumonia.All pig-raising countries all have this disease popular, and primary disease is caused by mycoplasma hyopneumoniae.The infection of piglets is mostly suffered from by contact caused by the sow of primary disease.Infected piglets relays other pigs again when weaning.Dense husbandry can promote that it is propagated.The incubation period of primary disease is longer, therefore has more swinery infected under not realized, causes primary disease often to be deposited in what swinery.The infection rate of primary disease is high, and mortality rate is low, but can cause retardation of growth and reduce meat change rate.In other words, the feeding period of pig listing will be extended.
Hyopneumoniae gas substance is one of 3 kinds of main pathogens causing porcine respiratory disease, suffers from recall rate in the case of respiratory tract disease be about 19% pig.Mycoplasma hyopneumoniae is mainly present in the respiratory tract of infected pigs, lung tissue, hilar lymph node and vertical phrenic lymph nodes, and sick pig and the pig that carries disease germs are its major source of infection.Its route of transmission mainly contains: respiratory infectious, direct contact infection and droplet transmission, source of disease Jun Zhi infected pigs; Initial infection mycoplasma hyopneumoniae is present in trachea and bronchus surface, and damages mucosa-cilium barrier, makes bronchus and blood vessel peripheral lymphoid like cell hypertrophy (immunoreation obviously participates in pathological development and causes lungs generation consolidation); Infected pigs mainly betides the later stage (after infecting 15 ~ 20 weeks) of disease to the immunne response of mycoplasma hyopneumoniae, and this infection has certain immunosuppressive action as can be seen here.
Primary disease clinical symptoms and dissection pathological changes, can for the reference in diagnosis.When large numbers of pig battle array dry cough, breathe, retarded growth or delay but very low mortality rate etc. and can suspect it is primary disease.Dissecting pathological changes is demarcate clear between the focus of lung and normal lung tissue, and lateral symmetry and diseased region mostly limit what point leaf, lobus cardiacus, middle leaf and every leaf front lower portion.There is the sensation that pancreas sample is solid.
When natural infection, easy secondary pasteurellosis bacillus, streptococcus pneumoniae, Actinobacillus pleuropneumoniae, Salmonella and various suppurative bacterium, mycoplasma hyorhinis and granular chlamydia etc., thus cause patient's condition to aggravate and mortality rate rising.
General antibacterial is as sulfanilamide, and penicillin, streptomycin and erythromycin etc. are all without therapeutical effect.A new generation's quinolones is the curative to primary disease optimum.The weak plain freeze-dried vaccine of mycoplasma pneumoniae of swine of domestic production can be used for 20-25 age in days sodium selenite, immunization rate can reach more than 80%.Kind of a swinery must be bred voluntarily in pig farm, and strict this encephalapthy agent of prevention invades.
Immunologic escape is caused because mycoplasma hyopneumoniae can change surface antigen, immunity is caused to weaken, therefore pig farm need coordinate medical treatment, general 3 ~ 5 days an of course for the treatment of, particularly farrowing sow spice purification, its pig that farrows is raised separately, use of not reserving seed for planting, segregated early weaning is carried out on the pig farm that condition possesses, and reduces the time of contact of sow and piglet as far as possible.
