What are the prevention and treatment methods for swine influenza?

Swine influenza is an acute, infectious respiratory disease of pigs, characterized by sudden onset, coughing, difficulty breathing, fever and rapid recovery. It is caused by influenza A virus (type A influenza virus), usually breaks out among pigs, is highly contagious but usually does not cause death. It occurs most frequently in autumn and winter, but can spread year-round. It is mostly identified as influenza C virus (type C influenza virus), or as one of the subtypes of influenza A virus.
Symptoms of Swine Influenza
Swine influenza has a high incidence rate, with an incubation period of 2 to 7 days and a disease course of about 1 week. In the early stage of onset, sick pigs suddenly develop fever, are listless, have reduced or no appetite, often lie together on their sides, are unwilling to move, have difficulty breathing, severe coughing, and discharge mucus from the eyes and nose. If treatment is not timely during the onset period, it is prone to complicate with bronchitis, pneumonia and pleurisy, etc., increasing the mortality rate of pigs. Body temperature rises to 40°C to 41.5°C, mental depression, reduced or no appetite, muscle pain, unwillingness to stand, sticky fluid discharge from the eyes and nose, conjunctival congestion, some sick pigs have difficulty breathing, panting, coughing, abdominal breathing, sitting-dog posture, wheezing of sick pigs can be heard at night, some sick pigs have joint pain, especially pigs in better body condition are more severely affected.
Treatment of Swine Influenza
1. There is no specific drug for this disease; only symptomatic treatment drugs can be used to relieve the condition and avoid the occurrence of secondary infections. Compound morpholine tablets or compound amantadine tablets and Banlangen granules can be tried for treatment, and the dosage can be determined according to the pig's body weight and the drug content.
2. Administer antibiotics or sulfonamide drugs to prevent bacterial infection.
3. For severely ill pigs, penicillin and streptomycin plus virusling can be injected intramuscularly at the same time, twice a day, for 5 consecutive days.
4. Adding antibiotics and antibacterials to the feed at a ratio of 0.2% can also effectively control the condition.
Prevention of Swine Influenza
1. Strengthen feeding management, increase the nutritional requirements of the pig herd, clean the environmental sanitation regularly, and promptly isolate and treat pigs that are already sick.
2. Qingkailing injection + lincomycin hydrochloride injection + potent amoxicillin, at 0.2 to 0.5 mL per kg of body weight, mixed and injected intramuscularly, once a day, for 3 consecutive days.

At the same time, add electrolytic multivitamins to the drinking water. After taking the above treatment measures, the condition was quickly controlled, and the whole herd recovered to health after 3 days.

5. Isolate promptly. Pens and feeding utensils should be disinfected with 2% caustic soda solution. Leftover feed and stagnant water should be deeply buried or harmlessly treated. Add 0.05% morpholine guanidine hydrochloride (virusling) to the pig's diet and feed for 1 week.
