Abstract

Gastric ulcer is a common disease among pigs in the whole world where an intensive
production occurs. It is mainly the upper region, the nonglandular region of the stomach that
is affected. Gastric ulceration is a disease with several risk factors. The factor that seems to
have the largest impact on the development of gastric ulceration is a small particle size of the
feed. The reported prevalence of gastric ulceration differs from 5 to 100 % and it is a large
herd-to-herd variation. Gastric ulcer is a disease that is hard to detect on the live animal
because the symptoms are difficult to interpret. It is not unusual to find healthy looking pig
that sudden die due to gastric ulcer. Some factors that have a positive impact on growth and
fed efficiency have a negative impact on the development of lesions and gastric ulceration in
the nonglandular region of the stomach. This relationship makes the prevalence of gastric
ulcer to be a problem that remains.
