Preliminary diagnosis: 1, influenza is a highly contagious viral disease. Once it happens, most pigs in the pigsty are infected within two or three days. The main symptoms are fever, cough, runny nose, severe abdominal breathing, muscle pain, depression and lethargy, but influenza generally does not cause obvious skin redness (except those with mixed feelings).

Treatment plan: 2. Is the temperature measurement of the sick pig confirmed? Generally, red skin and vomiting will make people think of serious diseases first, so it is best to find someone to draw blood for laboratory diagnosis in time, so that the results can be accurate and measures can be taken to minimize the losses. It seems that the seriously ill pigs were isolated and thoroughly disinfected. Pigs were treated conservatively, injected with hyperimmune serum once, and injected with compound sulfamonomethoxine sodium once a day for two or three days, and drank vitamin C water as much as possible to enhance their tolerance to diseases.

Usually, the swine fever vaccine must be done well.
