Clinical veterinaries are listed as a cold category of pig influenza and pork cold.Pig flu and pigs are mostly occurred in winter, causing certain economic losses to pig farmers. Through the analysis of the symptoms and causes of this type of disease, it provides reference for the scientific prevention diseases of farmers.

With the increasing demand for pork products in my country, my country’s pig industry has developed rapidly, and the occurrence of pig flu and pigs have caused serious economic losses to farmers.Because pig flu and pigs have colds in the category of colds, their clinical symptoms are similar, it is difficult to distinguish, and there are misdiagnosis.How to improve the diagnosis of pig influenza and pig colds in clinical clinic is the key to ensuring good treatment effects.

The disease has the characteristics of a high incidence of high incidence, which is not easy to cure.

In clinical diagnosis, compared with pig flu, there are few cases of pigs in a cold, and their onset has no significant seasonal characteristics.The changes in temperature and the nutritional condition of the pig itself can cause disease.In general, pigs with poor resistance and sows during pregnancy have a higher chance of catching colds.The sick pigs have significant symptoms such as cough, fever, loss of appetite, and mental deficiency. The disease occurs quickly and has a short latent period. After the initial active treatment, the sick pig will soon heal.In severe cases, it can lead to symptoms such as constipation and diarrhea.Seasonal changes, unsatisfactory hygiene, and disinfection measures will cause pigs to catch a cold.

4 prevention and treatment measures

4.1 Pig flu

Pig flu is contagious and should strengthen prevention.The breeding staff should ensure that the living environment of the pig group should be cleaned and regularly disinfection of pig houses. Before buying pig seeds, you should investigate the source of the species to avoid the pig breeding white body with virus. The serum of pigs should be tested regularly, and the influenza vaccine should be used to ensure that the pigs are guaranteed to ensure that pigsThe immune status of the group meets relevant national regulations and requirements.Traditional Chinese medicine treatment or combination of traditional Chinese and western medicine is often used to treat pig influenza.In the case of diagnosis of full -group infection, Chinese medicinal agents should be used for mixed feeding.The prescriptions adopted are as follows: Banlangen, dried ginger, licorice, large green leaves, honeysuckle, Wanzheng, Bupleurum, astragalus, mumato, nepeta each 25-50 grams, grind them into powder and mix with feed.The prescription is generally suitable for pigs with a weight of about 50 kg.For some sick pigs with poor appetite, you can make the prescription and take the juice at the same time, and you can use it once, and basically heal it.When necessary, take i the next day.Western medicine therapy mainly uses drugs such as injecting penicillin beerine, and the injection concentration of the drug should be reasonably allocated in combination with the weight and age of the diseased pig.The combination of traditional Chinese and western medicine can significantly improve the efficacy.

After diagnosis is diagnosed, isolation measures should be taken to avoid exacerbating infection.For the prevention and treatment of this type of disease, the establishment of a biological safety epidemic prevention system should be strengthened, focusing on quarantine and reducing the risk of infection.The two episodes are mostly in winter and are frequent stages of species. They should choose a well-represented pig farm and adopt pigs isolation measures. The breeders should strengthen the management of pig groups and ensure that the temperature of the pig house is controlled at 20^C-27C.In the weather changes, heat insulation measures should be taken to ensure ventilation in the house, reasonably allocate feed, and enhance the anti -infectious power of pigs.
