Measuring lameness prevalence: effects of case definition and assessment frequency

Data from an observational longitudinal study exploring lameness definitions, assessment frequencies and association between the lameness definitions and parity of dairy cattle. The data was collected at UBC dairy education and research farm. A sample of 282 cows were locomotion scored weekly and were followed from calving till 12 weeks in lactation.

本数据集源自一项针对奶牛跛行定义、评估频次以及跛行定义与胎次之间关联展开的观察性纵向研究。相关数据采集自英属哥伦比亚大学（University of British Columbia, UBC）奶牛教育与研究农场。研究共纳入282头奶牛作为研究样本，每周对其进行跛行运动评分，并从产犊后开始跟踪随访至泌乳第12周。
