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.

3. Runny nose, flu
4. Whiteness, weight loss
5. Uniform Poor degree
6. Increased secretions from the corners of the eyes, etc.
