We investigated factors involved in the etiology of mesenteric fat necrosis in Japanese black cattle using 32,586 cases in the carcass inspection database. The incidence was significantly higher in females than in castrated males and increased with age. It differed significantly among farms (P＜0.01). In addition, this disease was found to have a correlation to perirenal fat necrosis, gastritis, hemorrhagic inflammation, pneumonia and hepatitis in farms with a higher incidence rate. These findings suggest that sex, age and feeding management methods are related to the onset of mesenteric fat necrosis in Japanese black cattle.
