Answer: Comrade Mu Wang: According to the symptoms described, it is impossible to determine exactly what caused it. Generally, the cases that cause acute death of weaned piglets are roughly the following: 1. Piglet edema disease: autopsy of dead pigs showed edema of stomach wall, especially edema of large curvature of stomach; edema of mesocolon. 2, vitamin E, selenium deficiency (mulberry heart disease): visible acute hemorrhagic liver necrosis, skeletal muscle, myocardial edema, pale. 3. Salmonella sepsis: hepatosplenomegaly, mesenteric lymphomegaly, small white necrotic lesions in the liver. 4. Clostridium novelii disease: abdominal distension after death, chest and peritoneal fluid, hepatosplenomegaly. Prevention: Antibiotics should be added to piglet feed, and at the same time ensure that feed nutrition is comprehensive. Selenium and vitamin E should be supplemented appropriately in selenium-deficient areas to improve the environment and reduce stress. The above is for reference only.
