Popular characteristics
Sick people, animals and carriers of recessive infection are all sources of infection. The virus exists in the intestinal tract, excretes to the outside world with feces, and infects susceptible people and animals through the digestive tract. The disease spreads rapidly and mostly occurs in the cold season. Piglets and piglets are common. Adult pigs are generally occult infection.
Pathological changes
Diseased piglets are depressed, anorexic, vomiting, diarrhea, feces are yellow or gray, watery or paste. The lesions were mainly limited to the digestive tract (especially jejunum and ileum), the intestinal tube became thinner and the small intestinal villi shortened.
Prevention and cure measures
At present, there is no specific treatment for this disease, which mainly depends on strengthening feeding management and health measures to prevent it. The vaccine is still in the development stage. Sick pigs should be isolated to clean, dry and warm pig houses, strengthen nursing and minimize stress factors. Can give sick pigs oral glucose saline or compound glucose solution, pigs per kilogram of body weight oral gas 30ml, twice a day.
