Listening to the chest with a stethoscope, the alveolar breathing sounds in some parts are weakened and there are small bubble-like sounds. In some parts, on the contrary, alveolar breathing sounds rise and whistle.
Severe sick pigs have severe cough and difficulty breathing, so they need to open their mouths to breathe. Blue-purple skin appeared all over the body.
When suffering from foreign body pneumonia, the breathing gas is very unpleasant and smelly, and it is dirty and smelly from the nose.
The cause of pneumonia
Caused by a cold
Pigs get wet in the rain, pigsty is wet, cold, crowded, climate change, etc. Make pigs catch a cold and may get pneumonia.
Caused by foreign body stimulation
Pigs inhale irritating gas, swallow foreign bodies by mistake, inject drugs carelessly, and misplace the liquid medicine in trachea, which causes foreign body pneumonia in pigs.
Rapid prototyping. Piglets are the main disease groups in newly-built pig farms. During pregnancy, the sow's resistance decreases, and the rabbit's combat effectiveness decreases, so it will be infected with this disease. After pigs get acute swine pneumonia, there will be symptoms such as decreased appetite, increased respiratory rate and increased body temperature. With the further development of the disease, the pig's body humidity returned to normal, and the abdominal breathing and nose enlargement were aggravated. On the other hand, sick pigs will lose weight sharply due to loss of appetite and insufficient nutrient intake, and die of respiratory asphyxia.
If the sick pig has been sick for too long, the disease will change from acute plastic surgery to chronic plastic surgery, mostly in pregnant sows and fat pigs. The respiratory function of sick pigs recovered after a long illness, but the cough symptoms still existed, and a more serious cough appeared in the morning and evening when they were vegetarian. With the development of weapons, the respiratory function of sick pigs will be damaged, and most sick pigs will also cough up wet sputum.
