Swine asthma is also known as swine asthma, swine mycoplasma pneumonia or swine mycoplasma pneumonia. The pathogen is Mycoplasma hyopneumoniae, which has been translated as Mycoplasma. The pathogen is mainly found in the respiratory tract, lung and hilar lymph nodes of pigs.

Pig asthma is a chronic respiratory infectious disease, characterized by coughing and panting, high incidence, low mortality, affecting the growth and development of pigs, while easy to secondary infection of many diseases, to pig production has brought significant losses. There were no age, breed, sex and seasonality. The morbidity and mortality of suckling piglets and young pigs were higher, followed by late pregnancy and lactating sows. Cold, wet, rainy, improper feeding and management, poor sanitary conditions can induce the disease or aggravate the disease. Sick pigs after recovery with bacteria for a long time, some up to 1 year or so

1. clinical symptoms:

1. Acute symptoms

It is mainly found in newly infected areas and newly infected pigs. The sick pig had difficulty breathing, severe mouth breathing, and obvious abdominal breathing. The number of breaths increased dramatically, reaching 60-120 breaths per minute. The body temperature is generally normal, and the body temperature rises when there is a secondary infection. Appetite is greatly reduced or abandoned, gradually emaciated, the course of disease is generally 1 to 2 weeks, the sick pig often died of asphyxia, the mortality rate is higher.

2, chronic symptoms

From acute to acute, there are also some sick pigs that take chronic processes at the beginning, which are common in shelf pigs, fattening pigs and reserve sows in old epidemic areas. Long-term cough, the morning before and after eating and strenuous exercise is the most obvious, severe spasmodic cough can occur. There are often varying degrees of dyspnea, increased number of breaths, and abdominal breathing. Sick pig body temperature is not high, but thin, stunted. The course of the disease can be delayed to 2~3 months, some in more than half a year, the fatality rate is not high.

3, recessive symptoms

Can be from acute or chronic transformation, some pigs in good feeding management conditions, no symptoms, but with X-ray examination or autopsy visible pneumonia lesions. I occasionally see individual pigs cough, growth and development are generally normal. It is a hidden source of infection in parallel and vertical transmission. When the breeding management is poor, may appear acute or chronic symptoms, and even cause death

2. anatomical symptoms

Significant lung lesions, swelling, scuba, gas lung; the lower edge of each lobe of the lung appeared confluent bronchial pneumonia lesions, the boundaries are obvious. From "pork-like change" to "pancreatic change" or "shrimp-like change" (the initial lesion is red-gray, and the cut surface is like pork, commonly known as lung meat change, and the later is lavender, dark red, and grayish yellow, (increased toughness, commonly known as "pancreatic change")Secondary infection can be seen after pericarditis, pleurisy, lung and pleural adhesions.

3. prevention and control
