As far as raising chickens are concerned, it is very common for chickens to get sick. But sick chickens will cause people to spend more time on taking care of sick chickens, and they will also infect other chickens, causing economic losses. The causes of broilers are sick. Because of what?

1. Poor ventilation, the house is not ventilated on time, resulting in poor environmental quality in the chicken house, which will cause the chickens to suffer from respiratory diseases. If the ventilation is poor in summer, it will cause heatstroke and heat stress in the flock, and ammonia in the house. Excessive concentrations of gas and carbon dioxide will affect the health of the chicken.

2. The breeding density of the flock is too large. If excessive pursuit of high economic benefits, the environment will be deteriorated, and the respiratory diseases of the flock will be caused by the crowding.

3. The influence of stress factors, breaking the sputum, changing the feed or the temperature difference of thechicken battery cages, parasites, heat stress, etc., can cause stress response to the flock.

4. Lack of nutrients The lack of various nutrients required in the chicken body or the unreasonable proportion will result in a decline in the disease resistance of the chickens. Therefore, the farmers must pay attention to the various nutrients needed for the chickens during the breeding process.
