Locomotion scoring, lying behaviour and lesion recording during hoof trimming are all ways of evaluating hoof health in dairy cows. The objective of this study was to evaluate the relationship between these measures in a random sample of 1340 cows from 42 Danish dairy herds. The hypothesis was that locomotion scoring and/or the monitoring of lying behaviour could be used as tools to identify cows with hoof lesions, either of the horn or of the skin. Cows were locomotion scored, lying behaviour recorded and data on hoof lesions seen during hoof trimming collected. The results were analysed using logistic regression with hoof lesion as the outcome and locomotion score (1-5), mean duration of lying bouts, parity and lactation stage as explanatory variables. This analysis was undertaken for all types of lesions, for hoof horn lesions only and for skin lesions only. Odds of all hoof lesions and of skin lesions increased with increasing locomotion score and increasing mean duration of lying bouts. Odds of horn lesions also increased with increasing locomotion score, but there was no significant association between horn lesions and the mean duration of lying bouts. It was concluded that locomotion scoring and duration of lying bouts may be used as tools in the management of hoof health in dairy herds.
在奶牛蹄部修剪过程中，运动评分、卧姿行为和损伤记录都是评估奶牛蹄部健康的方法。本研究的目的是评估在来自 42 个丹麦奶牛场的 1340 头奶牛的随机样本中，这些措施之间的关系。假设是，运动评分和/或卧姿行为监测可以作为工具，识别出具有蹄部病变的奶牛，无论是角蹄病变还是皮肤病变。对奶牛进行运动评分、卧姿行为记录，并收集在蹄部修剪过程中观察到的蹄部病变数据。使用逻辑回归分析，以蹄部病变为结果，以运动评分（1-5）、卧姿持续时间的平均值、胎次和泌乳阶段为解释变量。对所有类型的病变、角蹄病变和皮肤病变进行了分析。所有蹄部病变和皮肤病变的几率随着运动评分的增加和卧姿持续时间平均值的增加而增加。角蹄病变的几率也随着运动评分的增加而增加，但角蹄病变与卧姿持续时间平均值之间没有显著的关联。结论是，运动评分和卧姿持续时间平均值可以作为奶牛场蹄部健康管理的工具。
