What is the symptom of chicken infectious bronchitis? How to treat it? What kind of medicine should I use?
Infectious bronchitis is an acute and highly contagious respiratory infectious disease in chickens caused by infectious bronchitis virus. What are the symptoms of chicken infectious bronchitis? How to treat it? What kind of medicine should I use?
1. Due to climate and various reasons, laying hens are easily infected with infectious bronchitis, which can cause weight gain and lower feed reward price, and mixed infection can cause pneumonitis to eliminate broilers in the process of processing, resulting in a decline in the number and quality of eggs.
two。 Infectious bronchitis (IB) is an acute, highly contagious, viral respiratory disease characterized by tracheal rales, coughing and sneezing. In addition, the disease may also affect the kidneys and cause a decline in the number and quality of eggs laid by laying hens. Chicks can die from respiratory or kidney infections.
3. Infectious bronchitis virus can replicate in respiratory tract, intestine, kidney and fallopian tube. the virus can spread rapidly in chicken flocks, and susceptible chickens in the same house with infected chickens usually develop symptoms within 48 hours. The virus could be isolated from trachea, lung, kidney and bursa of Fabricius from 24 hours to 7 days after aerosol inoculation. the isolation rate of the virus decreased with time and varied with different strains.
4. Although the persistence of infectious bronchitis virus infection has not been determined, long-term and intermittent detoxification proves that personnel and equipment contamination is a potential risk of transmission between chicken flocks.
5. Non-specific treatment of infectious bronchitis can reduce the loss caused by infectious bronchitis by improving feeding and management conditions, such as preventing cold stress, avoiding overcrowding and ensuring feed intake to prevent chicken weight loss. The use of appropriate antibiotics can reduce the loss caused by balloon inflammation. In Australia, it is recommended to add electrolyte substitutes to drinking water to supplement lost sodium and potassium to reduce the loss of glomerulonephritis. The recommended concentration of sodium and potassium is 72 (millimoles per liter) mmol/l, of which at least 1/3 are citrate or bicarbonate ingredients.
The best way to prevent and control the disease is to manage and vaccinate.
