Historical reports of hemorrhagic bowel syndrome (HBS) in swine describe infrequent, explosive outbreaks of sudden deaths with intestinal hemorrhage and no apparent infectious cause. Hemorrhagic bowel syndrome does not have a single, known etiology nor are specific risk factors consistently associated with the deaths. A diagnosis of HBS is applied only after thorough efforts to rule out other causes of rapid death and intestinal hemorrhage have been completed. The most common differential diagnoses are intestinal volvulus (twisted gut), the hemorrhagic form of porcine proliferative enteritis (PPE, ileitis), gastric ulcers, bacterial toxemia (e.g. acute infections with Salmonella or hemolytic E. coli), or other causes of sudden death. Control requires that one accurately rule out other known causes of sudden death, objectively assess environment and feeding practices, and properly manage risk factors that may be present. Reports of specific, consistently successful therapeutic interventions are rare.

Technological advances and an enhanced understanding of the finishing pigs needs have resulted in the application of new, innovative methods of housing and managing the finishing pig. Housing of finishing pigs in very large pens, containing 500 or more pigs, is now being practiced throughout the U.S. swine industry. Large pens can capture efficiencies of space and help alleviate problems associated with animal aggression and behavior. Application of automated sorting technology has improved animal handling within large group finishers while expanding producer opportunities to fine-tune management decisions regarding feeding, monitoring, and marketing finishing pigs. Enhanced management has allowed producers to capture economic benefits from finishing facilities while maintaining productivity and welfare of the pig. This fact sheet describes the industries current understanding of automatic sorting technology.
