How to prevent:
Environmental sanitation and feeding management of chicken houses are an important cause of this disease. Excessive concentrations of harmful gases such as ammonia and carbon dioxide in the air in the chicken house, excessive flock density, insufficient feeding space and drinking water space for chickens, vaccination, group transfer, and nutritional imbalance all lead to the occurrence of colibacillosis. There are colibacillosis and more cross-infection with other viruses, we should pay attention to comprehensive prevention and control.
1. Prevent chickens from drinking contaminated water. To disinfect the drinking water of chickens, add 0.5-1 grams of bleaching powder per kilogram of water or 0.5 mg of Chlorine per kilogram of water.
