Vertical fissures (sandcracks) affect approximately 20% of adult beef cattle in western Canada. The risk factors associated with the formation of these lesions are not well understood. This paper describes a case-control study that identifies the role of increased claw size (claw volume > 390 cm3, odds ratio 7.8) in the formation of the lesion. No connection was found between vertical fissures and horn hydration status. However, horn hydration was found to vary significantly between samples collected in the summer and winter, the latter samples having significantly reduced moisture content. The importance of these findings and the implications for the prevention of fissure formation are discussed.
垂直裂缝（砂裂）影响加拿大西部约20%的成年肉牛。与这些病变形成相关的风险因素尚未完全明确。本文描述了一项病例对照研究，该研究确定了爪尺寸增大（爪体积>390立方厘米，优势比为7.8）在病变形成中的作用。未发现垂直裂缝与角的水合状态之间存在关联。然而，发现夏季和冬季采集的样本之间角的水合情况有显著差异，冬季样本的水分含量显著降低。讨论了这些发现的重要性以及对预防裂缝形成的意义。
