Chronic respiratory diseases in ducks mainly refer to duck sinusitis, which has a high incidence. Infected ducks and sick ducks are the main sources of infection of the disease. In the process of raising ducks, duck sinusitis usually occurs in an environment with poor air quality and excessive humidity. Due to the poor environmental conditions of duck breeding, the incidence of duck sinusitis in duck breeding industry is generally high.

2. Duck colibacillosis.

Duck colibacillosis, also known as Escherichia coli septicemia, is an acute septic infectious disease caused by Escherichia coli. Duck Escherichia coli will do harm to ducks at every growth stage, and the infection rate of ducklings is much higher than that of adults. The environment of duck farm is poor, or the farm is poorly ventilated, or the ground of the farm is wet. Will lead to the occurrence of duck colibacillosis. Infected ducks and sick ducks are the main sources of infection.

3. Duck filariasis

Duck filariasis is a parasitic disease caused by ostrich nematodes. Under normal circumstances, the disease will occur in ducklings, and the main onset time is in autumn. The disease of ducklings is mainly due to their weak self-resistance, and duck filariasis has high infection efficiency and lethal efficiency.

Strengthen disinfection: clean up feces in time, change grass frequently, and isolate sick ducks in time when they are found. Disinfect duck houses, activity areas, etc. Use bleaching powder regularly, and provide enough rest space to prevent ducks from trampling when resting.

Pay attention to management details: set up a sand bath in the activity area of ducks, so that ducks can take a sand bath in their leisure time to remove parasites and residual feathers. The feed must be nutritious and free from mildew. Each duck house should prepare a set of special clothes and rubber shoes to prevent germs from being brought into the duck house through cross-contamination of clothes and soles.

In order to promote the healthy development of duck industry in China, it is necessary to analyze the common diseases in duck industry, clarify the causes and take targeted prevention and control measures to ensure the healthy growth of ducks and obtain more economic benefits.
