Rotavirus belonging to the Reoviridae rotavirus, can cause acute gastroenteritis in pigs, characteristics of acute diarrhea. 10 to 60 day old weaned pigs were vulnerable to disease, the incidence rate was 80%, mortality was 20%.
The epidemic characteristics of the disease is the main source of infection in adult recessive poison pigs and pigs, through the digestive tract and respiratory tract infection, endemic, have obvious seasonal, winter and spring multiple. Stress factors, especially cold and wet, bad health condition, the disease incidence and severity were greatly influence. The pigs once occurred of the disease every year, after the continuous occurrence.
Symptoms and lesions of various age and sex of the pigs can be infected with the disease, but in the affected areas as most adult pigs have been infected and acquired immunity, so the incidence of multiple of 60 day old weaned pigs below. The early onset of pig spirit fatigue, loss of appetite, vomiting, diarrhea, refused to move, stool watery or paste, black and white or dark. Pigs extreme exhaustion, prostrate, with thirst, persistent diarrhea leading to dehydration, acid-base imbalance after 4 ~ 7 days of death. Necropsy lesions are limited to the gastrointestinal tract. Gastric atony, filled with curds and milk, the thin, translucent, which is full of liquid, color yellowish gray or dark gray, intestinal villus shortening flat.
A comprehensive prevention and control, strengthen management, keep fold health, to promote warm in the cold work, reduce stress, strengthen the sow and pigs resistance. Two, in the affected areas as soon as possible let newborn pigs eat colostrum, which won the maternal antibody protection, in order to reduce the incidence of. Three, found that infected pigs, immediately be isolated to the clean, dry and warm in piggery strengthening nursing, reduce stress, remove feces and contaminated straw, disinfect contaminated environment and objects. Four, using glucose glycine solution (22.5 grams of glucose, sodium chloride 4.74 grams, glycine 3.44 grams, 0.27 grams of citrate, potassium citrate 0.04 grams, 2.27 grams of anhydrous potassium phosphate, dissolved in 1000 ml of water into) or oral rehydration salts solution (sodium chloride, 3.5 grams, 2.5 grams of sodium bicarbonate, potassium chloride 1.5 grams, 20 grams of glucose, 1000 ml water) to pigs free drinking, and symptomatic treatment, investment services convergence antidiarrheal agents, use of antibiotics and sulfa drugs, to prevent secondary infection, sodium bicarbonate solution intravenous injection of 5% glucose saline and 5% sick pigs, can prevent dehydration and acidosis.
