“…Claw health of dairy cows can be described using various key performance indicators obtained from different sources. Such sources include regularly determined lameness prevalences over a two-week interval [ 46 , 54 ], at the time of routine monthly milk performance testing [ 13 , 14 ], regularly registered veterinary diagnoses [ 55 ] and annually recorded culling reasons directly associated with claw and limb disorders [ 47 ]. Further important data sources are electronically recorded claw lesions assessed at each claw trimming visit [ 19 , 25 , 53 ] and regularly scored M-stages of digital dermatitis at two-week intervals in the milking parlour or during pen walks using a DD-app [ 56 ].…”

“…The 24 LKV employees had previously been trained in locomotion scoring for similar projects in recent years [ 13 , 14 ]. Additionally, these employees were retrained in locomotion scoring for the current project at a single commercial dairy farm by a single instructor in October 2019.…”

“…The negative impact of lameness on milk yield, fertility traits, animal welfare and premature culling has been described by numerous researchers [ 12 , 13 , 14 , 15 , 16 , 17 , 18 ]. The basis for efficient monitoring of claw health in dairy cows is the electronic recording of regularly assessed claw health data obtained at each claw trimming visit.…”

While benchmarking is already used for the assessment of performance gaps in cattle herd management and welfare concerns, its application to quantifying claw health performance is relatively new. The goal here was to establish a benchmarking system for claw health in Austrian dairy cattle. We used electronically registered claw health data of cows from 512 dairy herds documented by professional hoof trimmers, culling data from the same herds, and locomotion scores taken at regular milk performance testings in 99 dairy herds during 2020. Mean, median and the 10th, 25th, 75th, and 90th percentiles of the incidences of risk of lameness, 13 common claw lesions, and the annual culling risk directly related to claw and limb disorders were used as key performance indicators. Only validated data sets were used and participating trimmers and locomotion scorers had to pass interobserver reliability tests with weighted Cohen’s kappa values ≥0.61 indicating substantial interobserver agreement. This claw health benchmarking system is intended to be used henceforth in the transnational cattle data network (RDV) by all participating farmers and is also available for veterinarians and consultants, with the agreement of respective farmers.

“…The mean milk loss for cows suffering from septic subtendinous calcaneal bursitis has never been reported. However, milk losses for Austrian dairy cows showing locomotion scores ≥ 4 have been calculated with means of 319 and 602 kg of milk, depending upon the breed [ 31 ]. Alternatively, the mean annual milk yield of an Austrian dairy cow ranges from 7625 kg (for Brown–Swiss cows) and 7834 kg (for Fleckvieh cows) to 9117 kg (for Holstein cows) [ 32 ].…”

“…Therefore, prevention must focus on avoidance of deep sepsis at the CT region, particularly by early and adequate treatment of decubital wounds, by debridement, application of a bandage and temporary separation of affected cattle into well-padded recovery boxes. Nevertheless, prevention of these decubital wounds should start by optimizing the quality of cubicles and barns and their bedding and by regular hoof trimming of dairy cows approximately three times a year for prevention of painful claw lesions [ 6 , 14 , 31 ].…”

Septic subtendinous calcaneal bursitis in cattle commonly results from hock lesions, and less commonly from penetrating wounds. The goal of this retrospective study was to describe clinical and diagnostic imaging findings, outcomes, postoperative complications and postoperative survival times (SURV-T) in cattle with this condition. Clinical data from 29 cattle with a mean age of 4.1 years were included. Twelve (41.4%) cattle were assigned to group 1 (septic bursitis only) and 17 (58.6%) to group 2 (septic bursitis, concurrent bone infection at the calcaneal tuber (CT) and lesions of the superficial digital flexor tendon. Eleven cattle (37.9%) with comorbidities were euthanized after diagnosis due to poor prognosis. Surgical treatment was performed in 18 (62.1%) patients of which 15 showed full recovery and a median cumulative SURV-T of 23.0 months. The success rate of surgically treated patients was 100% (8/8) in group 1 and 70% (7/10) in group 2. There was no statistically significant association (p > 0.05) between the duration of septic bursitis and concurrent bone infection at the CT with occurrence of postoperative complications and SURV-T. However, there was a clear trend favoring more postoperative complications and shorter SURV-T in cattle with concurrent CT bone infection. In conclusion, cattle with septic subtendinous calcaneal bursitis exclusively have a good prognosis, provided adequate surgical treatment is performed.

Zusammenfassung Gegenstand und Ziel Die hier vorgelegte Arbeit soll eine aktuelle Bestandsaufnahme der Kühe der Hinterwälder Rasse in Baden-Württemberg und in der Schweiz vorlegen. Weiterhin sollen die Leistungsdaten und die registrierten Abgangsursachen der Hinterwälder Kühe mit denen der Vorderwälder-, Holstein- und Fleckviehkühe in Baden-Württemberg über einen längeren Zeitraum verglichen werden, um mögliche Unterschiede zwischen Extensiv- und Intensivnutzung aufzuzeigen. Material und Methodik Über einen Zeitraum von fast 70 Jahren, von 1953 bis 2021, wurden die entsprechenden Dokumentationen der Rinderunion Baden-Württemberg und deren Vorgängerorganisationen zusammengetragen und ausgewertet. Auch die Daten der Hinterwälder in der Schweiz, wo es seit 40 Jahren eine bedeutende Hinterwälder-Population gibt, wurden berücksichtigt. Ergebnisse Die Anzahl der Hinterwälder Milchkühe nimmt in ihrem ursprünglichen Verbreitungsgebiet der Höhenlagen des Südschwarzwalds stark ab, so dass zu befürchten ist, dass die Milch-Nutzungsrichtung dort verloren gehen könnte. Die extensive Nutzung der Hinterwälder für die Fleischgewinnung hat hingegen zugenommen; sie ist auch in der Schweiz die bevorzugte Nutzungsart. Im Vergleich mit Vorderwälder-, Holstein- und Fleckvieh-Kühen stieg die Milchleistung bei Hinterwälder Kühen im Untersuchungszeitraum nicht wesentlich an, jedoch waren die Gesundheitsdaten, im Besonderen die der Reproduktion, die der Euter-, Klauen- und Gliedmaßengesundheit sowie der Langlebigkeit herausragend. Im Vergleich mit den hochleistenden Milchkühen über die Jahrzehnte wurde deutlich, dass der starke Anstieg der Leistungen von den Tieren mit einer stetig ansteigenden, hohen Krankheitsprävalenz und damit zusammenhängend einer zu kurzen Lebensdauer bezahlt wird. Schlussfolgerungen und klinische Relevanz Die kleinste Zweinutzungsrasse Mitteleuropas konnte bisher noch durch die Resilienz der Tierhaltenden, durch das Engagement privater Organisationen sowie nicht zuletzt durch staatliche Hilfen überleben. Ihre herausragenden Fitnesswerte machen sie für künftig wieder vermehrt notwendige, nachhaltige Haltungsformen bestens geeignet, gerade im Hinblick auf die sich schnell manifestierende Klimaänderung. Sie und andere Rassen müssen als wertvoller Genpool weiterhin unterstützt und erhalten werden.
