Abstract：
The control of digital dermatitis (DD) among cattle is crucial; however, effective and environmentally-sound control measures have yet to be identified. From the monitoring data of DD which were recorded during regular hoof trimmings in a farm in Hokkaido, Japan, we detected a decrease in the DD prevalence in a herd where an anaerobic bacterial fermentation enhancer (ABFE) was distributed. The possible effect of ABFE was analyzed using a retrospective repeated cross-sectional design. The prevalence of DD decreased over time in the ABFE-distributed group. Furthermore, a selected regression model indicated the time-dependent enhancement of the decreasing trend. While potential coincidental factors may influence, this study provides a basis for further research on the preventive effect of ABFE against DD.
摘要：
控制牛的指性皮炎（DD）至关重要；然而，尚未确定有效和无害环境的控制措施。根据北海道某农场定期修剪蹄时记录的DD监测数据，Japan,我们发现在分布有厌氧菌发酵增强剂（ABFE）的牛群中DD患病率降低。使用回顾性重复横截面设计分析了ABFE的可能影响。在ABFE分布组中，DD的患病率随时间下降。此外，选定的回归模型表明下降趋势的时间依赖性增强.虽然潜在的巧合因素可能会影响，本研究为进一步研究ABFE对DD的预防作用提供了依据。
