Chicken chronic respiratory disease (Chronic Respiratory Disease, CRD) is one of the common diseases affecting the poultry industry, although the mortality rate is low, but can cause a lot of ways to diversify and morbidity and following the disease, spread, spread very quickly. Mycoplasma vaccine development and promotion of the disease, there are some problems, drug prevention is still necessary. Makes the emergence of resistance in a large number of antibiotics, the chicken chronic respiratory disease still can not be effectively controlled. CRD Veterinary dialectical undoubtedly the lung and stomach excessive heat, thermal Yu phlegm obstruction the appropriate Qingfei Xiere, Yang Wei Yi Yin. The white tiger soup \Research purposes: 1. \2. Pharmacodynamic indicators to explore the white tiger soup \Research methods: 1. Double dilution method \sub-MIC conditions for 48h morphology and ultrastructure. 2. White tiger soup \The modeling week after respiratory symptoms, MG antibodies. A group for the healthy control group, B group for pathological control group, only modeling treatment; C group for the white tiger soup high dose treatment group (4g/kg); D group for white tiger soup dose treatment group (2g/kg); Group E is the white tiger soup low dose treatment group (1g/kg); Well if gatifloxacin F group control group (0.5mg/kg) administered once daily for five consecutive days, and each day after the administration 0h 2h, 4h, 8h, 12h blood collection, A and B, two groups simultaneously measured the dynamic changes of plasma SOD and MDA values. 3. \changes. The results: 1. Vitro antibacterial experiments measured: \/ mL. Electron microscopy results for: white tiger soup \2. Influence the results of the \White Tiger Decoction treatment group SOD values ??have increased the value of MDA, five days after treatment with no significant difference in group A, and with B group differences significant. That \3. White tiger soup \Modeling, 8 days, the epithelial cell shedding, tissue fibrosis, lumpy positive material decrease in SP-A positive cells fuzzy morphology SP-A positive cells; 12 days almost no positive reaction reduced the degree of staining. After three days of treatment, the increase in the C group SP-A positive cells, expression was strongly positive, visible more clearly positive cells. Group D SP-A positive cells increased expression weakly positive, positive cells than fuzzy morphology. Four days after the treatment, the E group SP-A positive cells increased staining intensity was significantly reduced compared with groups C, D to increase slowly. F positive cells were observed in a small number of SP-A was weakly positive reaction. The results showed that the \Conclusion: 1. White tiger soup \2. Pharmacodynamics: \
