What to Do About Purple Pig Ears? Cause Analysis and Prevention and Treatment Methods
What to do about purple pig ears? Causes of purple pig ears and prevention and treatment!
Blue ear disease generally has a high mortality rate and a short course when it appears. There are many types of pig ear bluing, including blue edges of the ears, blue at the base of the ears (possibly with no death for many days after appearance), and the entire ear turning blue (with a very fast death rate: a little purple is seen in the morning, by the afternoon the ears are very purple, the whole body is also purple, and then the pig dies at night).
Blue pig ears should be considered in two situations: is it hemorrhage or congestion? Press firmly on the ear for one or two seconds, then release, and see whether the blue area fades (turns white). If it fades, it indicates congestion; if there is no change, then it is hemorrhage.
Congestion at the extremities is due to right heart failure.
⟧ Hemorrhage is a manifestation of septicemia. The lesions of septicemia are often reddening of the skin, especially the abdomen. Pulmonary edema, and hemorrhagic spots of varying degrees in multiple organs (sometimes they may not necessarily be found; hemorrhagic spots alone cannot be distinguished from swine fever).
⟧Causes of blue (purple) ears in pigs
⟧Pulmonary dysfunction refers to inflammatory changes in the lungs caused by various causes (such as swine fever, streptococcosis, infectious pleuropneumonia, asthma, blue ear disease, pseudorabies, bacterial pneumonia, anaerobic bacterial pneumonia, toxoplasmosis, circovirus disease and wind-cold common cold, etc.), resulting in a decline in the ability of the alveoli to exchange oxygen, a decrease in oxygen content in the blood, an increase in carbon dioxide content, darkened blood color, and areas of congestion and hyperemia tending to show dark red-purple.
⟧Cardiac dysfunction refers to a decline in the heart's pumping and circulatory function, with blood circulation being obstructed, causing congestion at the extremities (ear edges, under the abdomen, eyelids, etc.). Causes that can lead to cardiac dysfunction, such as infectious pleuropneumonia, can cause increased pericardial fluid, cardiac hypertrophy and weak contraction; when pulmonary dysfunction has a somewhat longer course, this situation can also occur.
⟧When pulmonary function and cardiac function are impaired at the same time, the congestion appearing at the extremities is blue (purple). Therefore, the appearance of blue (purple) ears in pigs is not a basis for judging a particular infectious disease.
⟧When purple ears appearTreatmentPrinciples
⟧As mentioned above, there are many causes that can lead to purple ears. Swine fever, streptococcosis, infectious pleuropneumonia, asthma, blue ear disease, pseudorabies, bacterial pneumonia, anaerobic bacterial pneumonia, toxoplasmosis, circovirus disease and wind-cold common cold can all cause purple ears.TreatmentPrinciples: treat pneumonia, prevent mixed infection, strengthen the heart.
⟧Treating pneumonia means that the causes that can lead to purple ears will all cause lung lesions to varying degrees. Targetedtreatmentof pneumonia and restoring lung function arethe key to treatingpurple ears.
⟧Preventing mixed infection means that the causes that can lead to purple ears are mostly mixed infections.
⟧Duringtreatment, carry out differential diagnosis, pay attention to mixed infection, and adopt differenttreatmentplans according to different causes.
⟧Strengthening the heart means that while treating pneumonia and mixed infection, drugs with cardiac-strengthening effects such as dexamethasone sodium phosphate or caffeine sodium benzoate are used in combination to promote cardiac function, improve blood circulation, and relieve and eliminate the symptoms of purple ears.
