Hemorrhagic bowel syndrome (HBS) is a poorly understood, sporadic and often fatal disease in cattle. Although, HBS is considered an important disease in dairy cattle, epidemiological data is largely lacking. This study describes the epidemiology of HBS in Belgium and the Netherlands, based on necropsy records from 2009 to 2022, and reports characteristics from 27 cows and 35 dairy operations with HBS, gathered through a survey. The annual incidence of HBS has a significantly increasing trend both at cow and herd level, with incidence above 3.2% in necropsied mature dairy cattle in the most recent years. Estimated herd-level incidence in the Netherlands was double the estimated incidence in Belgium, which might be explained by higher herd size in the Netherlands. Occurrence of HBS was most prevalent in fall, being 40.1% higher than the average of the other seasons. In 35 Flemish (Belgian) surveyed dairy herds with HBS, manifestation of HBS was mostly as solitary cases, and if multiple cases occurred, the time interval was highly variable. In addition, the majority of cows with HBS (61.1%; 16/26) were in more than 100 days lactation. In conclusion, HBS is an important and possibly emerging disease in dairy cattle in Belgium and the Netherlands.
出血性肠综合征（HBS）是一种在牛群中了解甚少、散发且往往致命的疾病。尽管HBS被认为是奶牛的一种重要疾病，但流行病学数据在很大程度上仍然缺乏。本研究基于2009年至2022年的尸检记录，描述了比利时和荷兰HBS的流行病学情况，并报告了通过一项调查收集到的27头患有HBS的奶牛和35个奶牛场的特征。HBS的年发病率在奶牛和牛群层面均呈显著上升趋势，近年来尸检的成年奶牛发病率超过3.2%。荷兰估计的牛群层面发病率是比利时估计发病率的两倍，这可能是由于荷兰的牛群规模更大。HBS的发生在秋季最为普遍，比其他季节的平均水平高出40.1%。在接受调查的35个佛兰德（比利时）患有HBS的奶牛场中，HBS的表现大多为单个病例，如果出现多个病例，时间间隔差异很大。此外，大多数患有HBS的奶牛（61.1%；16/26）处于泌乳100天以上。总之，HBS是比利时和荷兰奶牛中的一种重要且可能正在出现的疾病。
