Sudden deaths of finishing pigs in modern pig herds cause economic losses and therefore draw constant attention worldwide. In the case of peracute mortality associated with gastrointestinal bleeding, pigs usually die during a short period without clinical manifestations. Necropsy can detect bleeding into various parts of the digestive system. Determining the exact aetiology of the sudden death can be difficult in many cases. Diseases and conditions such as gastric ulcers, abdominal torsion, haemorrhagic bowel syndrome and infectious diseases should be taken into account in the differential diagnosis. Because some of these diseases still have an unclear aetiology and pathogenesis, the aim of our work was to provide a summary of existing knowledge as well as to describe related pathognomonic pathological changes.
