Swine enzootic pneumonia is a common disease of pigs in the process of pig raising, which will seriously affect the development of pig production and pig raising industry. Therefore, if farmers want to ensure the economic benefits of pig breeding, they must take effective measures to prevent swine enzootic pneumonia.Prevention and control, which is also the World Swine Industry Expo farmers always pay attention to the issue.

1The symptom of swine enzootic pneumonia

1.1 Latent infection

Latent infection is usually difficult to detect, and the pig with latent infection is not much different from the ordinary pig, but if you look carefully, you will find that the pig with latent infection will have symptoms such as decreased appetite and slow growth.

1.2. Chronic infection

Chronically infected pigs, the disease will last for a long time, and there will be symptoms such as cough, wheezing, poor breathing, when the outside temperature rises suddenly, piglets will appear cough, especially when eating and drinking, there will often be cough, and sick pigs will also appear runny nose phenomenon, in the later period, Constipation, visual mucosal cyanosis and other symptoms may also occur.

1.3 Clinical manifestations of acute infection

The disease is characterized by sudden onset, and infected pigs only have symptoms such as low mood, loss of appetite, shortness of breath, and elevated body temperature.

2 Epidemiological characteristics of swine enzootic pneumonia

2.1 Higher incidence in piglets

There is a high incidence of swine enzootic pneumonia in piglet populations and it is highly contagious. The difference with adult swine asthma is that the piglet disease occurs in a dominant form and is usually sicker and more contagious.

2.2 High scale incidence

The transmission route of Swine enzootic pneumonia is not only airborne, but also not limited to contact transmission, so the spread of this disease is wider, the spread of this disease is larger, therefore, the spread of this disease is faster, once it occurs, it will spread in a very short time, there will be a large area of spread and the incidence is very high.

2.3 Seasonality is obvious

Swine enzootic pneumonia is highly time-sensitive. Although outbreaks may occur in all seasons, they occur more frequently in cold winter months.

3 Swine enzootic pneumonia prevention and control

3.1 Improvement of pig raising environment

As far as swine enzootic pneumonia is concerned, sick pigs and infected pigs are the main source of infection and also cause swine enzootic pneumonia

An important reason. Even if a pig's swine enzootic pneumonia is treated, the germs will still lurk in the pig's trachea. To change this situation, it is necessary to improve the conditions of pig raising and strengthen the environmental management of pig raising.

3.2 Timely implementation of feeding isolation

In the pig feeding and quarantine, the mobile pig must be comprehensively and carefully inspected and isolated from the relevant production area, the isolation period is three months, and the mixed culture can be carried out if the inspection is qualified after the end of the isolation.

3.3 Do a good job in the injection of preventive breeding vaccines

In raising pigs, the best way to prevent diseases is to inject piglets with the attenuated freeze-dried vaccine for porcine asthma. The vaccine is used for preventing porcine asthma, and freeze-dried vaccines are generally used for intrapulmonary injection

3.4 To strengthen the quality of piglets

Pigs have a high sensitivity to swine enzootic pneumonia and are highly infectious, so the quality of pigs must be strictly tested when they are introduced. Adhere to the pig self-breeding, as far as possible to reduce the introduction of foreign breeding pigs, when the breeders buy piglets, be sure to choose a formal business license, operating in good condition of the pig farm.

3.5 Drug Prevention

In order to effectively prevent swine enzootic pneumonia, antibiotic drugs such as Timicosin, flufenicol and linum hydrochloride can be applied in time to enhance the immune capacity of swine population.

4 Treatment Methods

4.1 TCM Therapy

Pig asthma is generally caused by wind cold, and may also be caused by hot weather, but if the disease is slow and the symptoms are mild, it can be treated by traditional Chinese medicine. For example: Honeysuckle 10 g, Polygala 10 g, Clover 10 g, Draba 10 g, almond 5 g, melon 5 g, loquat 5 g, Aristolochia 5 g, dragon 5 g, licorice 3 g, Perilla 3 g. All the herbs were ground into powder, then mixed with food and fed three times a day. If it is a mildly sick pig, it can play a very good role.

4.2 Western Medicine

Western medicine is characterized by quick results, but it also has a certain irritation. Western medicine usually uses antimicrobials, mainly lincomycin and oxytetracycin bases. There is also the option of intramuscular injection, the effect of antibiotics is rapid and significant.

4.3 Toad ear coating treatment

The toad is a very poisonous amphibian. Toad pulp is a common agent, this agent is toxic, but has a strong anti-inflammatory effect, and has a good therapeutic effect on swine asthma.

5 Summary

Swine asthma is a high-risk disease of pigs, which can easily lead to a large number of deaths of pigs. It is very harmful to pigs and has a great impact on the economic interests of pig farms. Therefore, farmers should always pay attention to the health status of pigs, understand the etiology, pathology and prevention and control measures related to swine asthma, and take timely actions when found to avoid major economic losses caused by asthma disease. If the piglet has sudden asthma, it must be effectively treated under the guidance of the farm veterinarian.
