Reasons for the high incidence of respiratory diseases in winter:

1. The climate is cold and dry, and the temperature difference between day and night in the pig house is large. The respiratory system is stimulated by cold air and the defense function of the tracheal mucosa is reduced;

< p>2. For the sake of keeping warm, the ventilation in the house is poor, which makes it easier for the spread of pathogens;

3. The mixing pattern of pigs of different ages or different origins;

4 , the overall health of the upstream pig herd is poor.

The main clinical symptoms are:

1. Decreased feed intake

3. Runny nose, flu

4. Whiteness, weight loss

5. Uniform Poor degree

6. Increased secretions from the corners of the eyes, etc.

Principles of prevention and treatment: prevention first, treatment as a supplement.

In the breeding industry, the principle of prevention and control of respiratory diseases in winter is "mainly to stabilize the disease, supplemented by the prevention of secondary infections", such as ring, mycoplasma, secondary infections of the chest, and at the same time, do a good job in the pig house Heating and ventilation measures.
