Gastric Ulcers: An Under-Recognized Cause of Mortality and Morbidity

摘要

Ulceration of the pars oesophagea is a common cause of death loss in the grower-finisher stage of pig production, and to a lesser extent, a cause of mortality in the sow herd. Stomach lesions can occur in glandular regions but these tend to be uncommon and generally associated with systemic diseases and will not be discussed in this paper. The cause of pars oesophagea ulceration is not fully understood, but some of the important risk factors have been identified. Despite this relatively good level ofunderstanding, the prevalence of gastric lesions at slaughter and the mortality rate due to gastric ulceration has increased over the past decade, and this problem has become one of the most important causes of death loss in the late finisher stage of production on many farms.
