Abstract

There seems to be either an acute, sudden-death syndrome or the subclinical, asymptomatic condition seen only at the time of slaughter. Generally only one pig in a herd dies, but losses do vary from a single pig to approximately 50% death loss do occur with stress from management or environmental changes, other changes, other disease, or immunization. One slaughter house observation (representing the subclinical syndrome) reported a 53% incidence. Another similar study of 443 slaughtered hogs showed 86% abnormal cornification of stomach linings, which is an early stage of any beginning ulcer.
