Abstract:Porcine pneumonia is an acute, febrile infectious disease of pigs caused by Pasteurella multocida, also called Pasteurellosis or hemorrhagic septicemia. This is often characterized by acute sepsis and hemorrhagic inflammation of tissues and organs. Pigs of all ages can occur, which is more harmful to the pig industry. This paper expounds the diagnosis and prevention process of Tibetan swine pneumonia in a Tibetan pig farm, and provides a reference for the prevention and control of the disease.
