Replication Data for:Standing behavior and sole horn lesions: a prospective observational longitudinal study

Data from a prospective observational longitudinal study examining the relationship between sole hemorrhages or sole ulcers in peak to mid-lactation and time standing during the weeks around calving. A convenience sample of 8 dairy cattle herds were visited every other week, and animals without previous severe horn lesions and deemed sound at 4 to 8 wk before calving were enrolled. Standing behavior was measured with data loggers attached to a rear leg, and standing time and duration of the longest standing bout were determined for each cow. Standing behavior was summarized into 3 periods: before (d -14 to -2), around (d -1 to 1), and after (d 2 to 14) calving. Average daily standing time and average daily longest standing bout were determined for each cow and period.

本数据集源自一项前瞻性观察性纵向研究，旨在探究泌乳高峰期至泌乳中期奶牛的蹄底出血（sole hemorrhage）与蹄底溃疡（sole ulcer），与产犊前后数周内站立时长之间的关联。本研究采用便利抽样设计，选取8个奶牛群并每隔一周开展一次访视；将产犊前4至8周时无既往严重蹄角质病变、且经评估蹄部健康的奶牛纳入研究队列。通过安装于后肢的数据记录仪（data logger）采集站立行为数据，并测定每头奶牛的站立总时长与最长单次站立持续时长。研究将站立行为数据按产犊节点划分为三个阶段：产犊前（第-14至-2天）、产犊期（第-1至1天）以及产犊后（第2至14天）。针对每头奶牛的各阶段数据，分别计算其日均站立总时长与日均最长单次站立持续时长。
