摘要

目前,爪伤的流行率和发病率被用作爪健康基准的参数。本研究的目的是利用牛群的牛爪健康指数(FCS)和个体的牛爪健康指数(CCS)建立一个牛爪健康基准系统,并对奥地利三个主要奶牛品种的牛爪健康状况进行基准测试。对来自奥地利 508 个奶牛场的 17,642 头奶牛的牛爪健康数据进行了分析。根据记录的牛爪病变及其三个严重程度,采用几何加权评分法计算出 CCS 和 FCS。每个奶牛场的 FCS 被划分为五个百分位阈值(P10、P25、P50、P75、P90),而 FCS 是根据每个牛群的 CCS 中位值计算得出的。此外,还使用爪伤发病率和 CCS 值对三个品种(弗莱克维赫牛、荷斯坦牛和棕瑞牛)的爪伤健康状况进行了基准测试。计算 FCS 中位数时,P50 及以下的牧场 FCS 为 20.0,表明爪伤健康状况非常好。然而,P90 级牧场的 FCS-MEDIAN 值为 67.5。对所考虑的 14 种牛爪病变的发病率和 CCS 值进行评估后发现,与棕瑞牛(CCS-MEDAN:12.0)相比,弗莱克维赫牛(CCS-MEDAN:24.0)的牛爪健康状况明显较差(P < 0.0001),紧随其后的是荷斯坦牛(CCS-MEDAN:22.7)。使用CCS和FCS作为主要的牛爪健康指标,可在基准系统中快速评估奶牛个体和牛群的现状。通过查看相应电子文档系统中显示患病率(尤其是与跛足相关的患病率)的诊断列表,可轻松查看每头奶牛和奶牛群的详细爪部健康信息。

Benchmarking claw health across three dairy cow breeds in 508 dairy farms using numerical claw health indicators

Currently, prevalence and incidence of claw lesions are used as parameters for benchmarking claw health. The aims of this study were to create a benchmarking system for claw health utilizing the claw health indicators Farm-Claw-Score (FCS) for the herd and Cow-Claw-Score (CCS) for the individual animal, and to benchmark claw health of the three predominant dairy cattle breeds in Austria. Claw health data from 17,642 cows from 508 Austrian dairy farms were analyzed. The CCS and FCS were calculated based on recorded claw lesions and their three severity levels using geometrically weighted scoring. The FCS of each of the dairy farms was classified into five percentile thresholds (P10, P25, P50, P75, P90), with the FCS calculated using the median value of CCS in each herd. Furthermore, claw health was benchmarked for three breeds (Fleckvieh, Holstein, Brown Swiss cows), using claw lesion prevalences and CCS values.

When the median FCS was calculated, dairy farms in P50 and below had an FCS of 20.0, indicating very good claw health. However, P90 farms showed an FCS-MEDIAN of 67.5. Evaluation of the prevalences of the 14 claw lesions considered and the CCS values revealed that Fleckvieh cows (CCS-MEDIAN: 24.0), followed closely by Holstein cows (CCS-MEDIAN: 22.7) had significantly poorer claw health (P < 0.0001) compared to Brown Swiss cows (CCS-MEDIAN: 12.0). The use of CCS and FCS as primary claw health indicators allowed for a quick assessment of the current state of an individual cow and a dairy herd in a benchmarking system. Detailed information on the claw health of each animal and the dairy herd can be easily reviewed by examining diagnosis lists that display prevalences, particularly those related to lameness, in the respective electronic documentation systems.
