Hemorrhagic Bowel Syndrome (HBS) is a sporadic, highly fatal disorder of adult dairy cattle. It is characterized by acute necrohemorrhagic enteritis that primarily affects the small intestine. Affected animals develop large intraluminal blood clots that result in obstruction of single or multiple segments of small intestine. HBS could be defined as a multi-factorial syndrome. Clostridium perfringens type seems to play an important role in the pathogenesis of this syndrome. The Authors analyzed the risk factors and set up a preventive plan based on correction of feed management practices and immunoprophylaxis in a Brown Swiss dairy farm with a history of sporadic peracute death losses and 3 diagnosed cases of HBS. The herd owner and the local veterinary practitioner put into practice the preventive strategies arranged to reduce the potential risk factors. No deaths were reported during the 6 months after vaccination and the feed management interventions. While further studies are expected to provide better understanding of the pathogenesis and risk factors of this syndrome, as well as progress in vaccination strategies, good management and feeding practices remain the best means of preventing HBS in cattle.
