What kind of disease is colibacillosis

Duck raising equipment has now been recognized by most people and used by most duck raising places. Although duck raising equipment can assist duck raising and ensure the cleanness and hygiene of the farm, duck raising equipment can not prevent the occurrence of colibacillosis. Colibacillosis is a kind of acute or chronic disease caused by pathogenic Escherichia coli. It is very lethal and has harmed many poultry breeding industry recently.
The incidence rate of infection is very high due to colibacillosis, which is able to infect ducks of all ages. However, due to the different environment of farms, some farms with relatively good environmental hygiene control have a low prevalence rate, while the poor farms with poor environmental hygiene control without using duck farming equipment have a higher incidence. The incidence rate and mortality rate of this disease are quite different. Ducklings passed through acute septicemia, while adult ducks mainly suffered from subacute and chronic infection. In most cases, due to the influence of various stress factors and other diseases, the infection of this disease may be very serious. The disease often occurs in adult laying ducks before opening. The addition of dead Amoy rate affects laying, and the production performance cannot be fully developed. After the disease occurred in the breeding duck farm, it directly affected the hatching rate and hatching rate of the eggs. Colibacillosis can occur all the year round, but it often occurs in rainy, hot and humid seasons. Poor ventilation, poor sanitary conditions and high density of culture are the main causes of the disease.
