1. Reasons for purple ears in pigs

Pulmonary dysfunction refers to inflammatory changes in the lungs caused by various causes, resulting in a decrease in the ability of the alveoli to exchange oxygen and a decrease in the oxygen content in the blood. The blood color decreases, the carbon dioxide content increases, the blood color becomes darker, and the areas with congestion and congestion tend to appear dark red-purple.

Heart dysfunction is a decrease in the pumping and circulation function of the heart, obstruction of blood circulation, and congestion in the periphery. Causes that can cause cardiac dysfunction, such as infectious pleuropneumonia, can cause increased pericardial fluid, cardiac hypertrophy, and contractile weakness; this may also occur when pulmonary dysfunction occurs for a longer period of time.

When lung function and heart function are impaired at the same time, the congestion that appears in the peripheral parts will be purple. Therefore, the appearance of purple ears in pigs is not a basis for judging an infectious disease.

2. Treatment principles for purple ears

As mentioned above, there are many causes of purple ears, such as swine fever, streptococcus, contagious pleuropneumonia, and asthma. Diseases such as blue-ear disease, pseudorabies, bacterial pneumonia, anaerobic pneumonia, toxoplasmosis, circovirus disease, and colds and colds can all cause purple ears. Treatment principles: treat pneumonia, prevent mixed feelings, and strengthen the heart.

Treatment of pneumonia refers to the causes of purple ears, which will cause lung lesions to varying degrees. Targeted treatment of pneumonia and restoration of lung function are the key to treating purple ears.
