Epidemic Status:
Bronchial embolization is one of the important diseases with high mortality rate and serious impact on breeding, which occurs frequently from October to May of the next year, mainly showing clinical respiratory symptoms, blackening of lungs, bronchial embolism and bursal inflammation in dissection. This disease is closely related to the seasonal climate change, breeding management, biological safety, animal immunity, vaccine immunization and animal health care, the disease has always been on of the most important diseases of various breeding enterprises in winter and spring.
Pathogenesis:
1. Inducement:
(1) Climate change: the temperature difference between day and night is large and poor insulation performance of the breeding farm to cause cold stress reaction.
(2) Feeding management: temperature, ventilation, humidity and other factors in chicken farm
Cold stress reaction is the main inducement for bronchial embolization: In the process of feeding and management, the humidity is too low or the transient and continuous cold stress will cause the contraction of the tracheal mucosa, reduce or stop the cilia beat, and decline the ability to remove pathogenic microorganisms and dust. The pathogenic microorganisms will enter the blood through the damaged tracheal mucosal system, causing a series of symptoms of the trachea and the body.
(3) Body immunity: immunosuppressive disease lead to the decline of immunity and failure of vaccine immunization.
2. Pathogenic factors:
(1) Viral disease: The detection rate of mixed infection of IB and H9 in the chicken farm with the bronchial embolization is high, which is also recognized as the most important pathogenic factor in the industry.
(2) Bacterial diseases: Mycoplasma. E-coli and Avibacterium nasotracheitis mostly participate in secondary infection, which aggravates the mortality rate of the chickens.
Prevention Plan:
1. Feeding management: manage the temperature, humidity and ventilation control to reduce cold stress reaction.
2. Biological safety: disinfection to reduce the number of pathogenic microorganisms (Empty disinfection: Oufudi / Animal disinfection: Weilike).
