The objective of this study was to evaluate risk factors associated with foot lesions and lameness in Swiss dairy cows. Potential risk factors were recorded by means of examination of 1'449 Swiss cows and the management systems of 78 farms during routine claw-trimming, and during personal interviews with the associated farmers. Statistical analysis of animal-based and herd level risk factors were performed using multivariate logistic regression models. The risk of being lame was increased in cows affected by digital dermatitis complex, heel-horn erosion, interdigital hyperplasia, Rusterholz' sole ulcer, deep laceration, double sole and severe hemorrhages. Cleanliness, BCS, affection with other foot lesions, breed, importance of claw health to the farmer, frequency of routine claw-trimming, producing according to the guidelines of the welfare label program RAUS, and silage feeding were shown to be associated with the occurrence of some of the evaluated foot lesions and lameness. The identified risk factors may help to improve management and the situation of lameness and claw health in dairy cows in Switzerland and other alpine areas with similar housing and pasturing systems.
本研究的目的是评估瑞士奶牛足部病变和跛行的相关风险因素。在常规修蹄期间，通过检查1449头瑞士奶牛以及78个农场的管理系统，并与相关农民进行个人访谈，记录潜在风险因素。使用多变量逻辑回归模型对基于动物和畜群水平的风险因素进行统计分析。患有指皮炎综合征、蹄踵角质侵蚀、趾间增生、鲁斯特霍尔茨氏足底溃疡、深部撕裂伤、双蹄底和严重出血的奶牛跛行风险增加。清洁度、体况评分、其他足部病变的影响、品种、爪健康对农民的重要性、常规修蹄频率、按照福利标签计划RAUS的指导方针生产以及青贮饲料喂养与一些评估的足部病变和跛行的发生有关。所确定的风险因素可能有助于改善瑞士以及其他具有类似住房和放牧系统的高山地区奶牛跛行和爪健康状况的管理。
