[ Method ] Conventional Chinese medicine plate dilution method, plate punching method and test tube method were applied to screen Chinese herbal medicines against avian infectious laryngotracheitis virus based on chicken embryo inoculation experiment. [ Result ] Forsythia suspensa, Radix lsatidis, Isatis iadigotica, Lonicera japonica, Codonopsis pilosula, Astragalus membranaceus, Rhizoma Atractylodis Macrocephalae, C, tyeyrrhiza uralensis and Pericarpium granati had relatively strong anti-ILTV effect; among the Chinese herbal medicines against avian E. coli, Sanguisorba offwinalis, Fructus Mume, Rheum palmatum, Anemarrhena asphodeloides, Radix Scutellariae and Fagopyrum cymosum had relatively strong effect against avian E. coli Os, while other Chinese herbal medicines had relatively weak or no inhibitory effect on avian E. coli 0s and 05. [ Conclusion] This study laid the foundation for further development of Chinese herbal medicine compound preparations to treat avian infectious laryngotracheitis, avian colibacillosis and other viral diseases and bacterial diseases.展开更多

E Methodl ＂Pak Ning＂ with different dosage forms and dosage time were used to carry out clinical observation of artificial infectious and natural infectious ILT of chickens. [ Result] The therapeutic efficacy of ＂Pak Ning＂ oral liquid water was better than powder with high cure rate, the difference was significant （P〈0.05）. compared with Ribavirin, the difference was significant （P 〈0.01 ）, and the preventive effects of feeding in advance were very well. I Conctusionl ＂Pak Ning＂ plays an important role in the treatment and prevention of ILl- with strong infectiosity and high mortality.展开更多
