Abstract
A 3-year-old Jeju native black sow with sudden death was requested to the Jeju Self-Governing Provincial Veterinary Research Institute for diagnosis in July 2009. Because the pig died suddenly, we could not find any clinical signs. Gross lesions such as pulmonary edema, redness of heart, liver, kidney and lymph nodes were observed at necropsy. Histopathologically, there were severe eosinophilic meningoencephalitis, atrophy, degeneration and necrosis of laminar neurons, and neovascularization in cerebral cortex. Based on histopathological findings and history taking about temporal suspension of water supply, this case was diagnosed as salt poisoning of a Jeju native sow. In our best knowledge, this is the first report for salt poisoning of sow in Korea, especially in Jeju native pig.
