Description

Technical field: [0001] The invention belongs to the technical field of medicine and medical engineering, in particular to a medicine for preventing and treating chicken infectious laryngotracheitis. Background technique: [0002] The large-scale chicken industry in my country mostly adopts the method of cage breeding and house feeding. Although the amount of feeding per unit area has been increased, due to the influence of factors such as high density of chicken flocks, environmental pollution, and poor ventilation, it is very easy to induce respiratory diseases in chickens. The disadvantages of the disease are high in late autumn, early spring and winter every year. For example, chicken infectious laryngotracheitis occurs every year. This is a viral acute respiratory infectious disease. The infection rate of adult chickens is about 80-90%, and the mortality rate is about 20-30%. Mucous membrane congestion, swelling, and yellow-white viscous fluid in the pipeline; microscop...

Problems solved by technology

The vaccine is highly virulent and has biological characteristics of genetic reversion to ancestors. It is generally not used or used with caution. Symptomatic therapy, such as using Virusin+penicillin+streptomycin to drink water can alleviate the condition and reduce death, but the curative effect is too poor, and it has the potential legacy of drug resistance and drug residue; other commercially available veterinary drugs such as Kechuanning, laryngitis Although powders and the like do not have the disadvantages of the above-mentioned western medicines, there are some defects in the composition of the formula and the application method, or the curative effect is affected because the formula is not rigorous, or most of the traditional Chinese medicine powders are directly mixed and fed according to the instructions in the application method, which delays the disease. Chickens absorb the active ingredients of the drug, and the control effect is not satisfactory
