In the absence of selenium: the exudative quality of young chicks, muscle stomach and heart muscle disease of young turkeys, selenium plasma glutathione peroxidase and body weight gain decreased, and mortality increased. Ducks that died of selenium deficiency exhibited necrosis of myogastric and intestinal smooth muscles, myocardium, and skeletal muscles, as well as symptoms of hydrocephalus and ascites. Vitamin E and selenium have a coordinated effect on the prevention of these diseases. The severely selenium-deficient chicks showed poor growth and poor feather development, poor fat indigestion, pancreatic atrophy and fibrosis, and decreased selenium glucosylperoxidase activity in the pancreas. According to relevant reports, continuous sampling studies were performed on pancreatic lesions. The lesions began in six ages and showed the formation of vacuoles and transparent bodies of the exocrine pancreas. As the deficiency develops, the cytoplasm degenerates until the acinus is replaced by a ring of cells in which the fibrous tissue is embedded in the center of the cavity. Feeding 100IU/kg of vitamin E and promoting its absorption with bile salts can maintain a high level of plasma tocopherol, which can greatly reduce the incidence of exudative diathesis. The chicken's pancreas does not show exudative qualities until severely degenerated.
