Andere haltungstechnische Eingriffe bei K\u00e4lbern, wie Enthornung und Kastration, sind mit Stress und Schmerzen f\u00fcr das Tier verbunden. Auch eine weiter proximal, im Zwischenwirbelspalt durchgef\u00fchrte Amputation des Schwanzes hat erkennbare Auswirkungen auf das Tier. Dagegen gibt es zur Amputation der bindegewebigen Schwanzspitze bisher keine Studie, die entstehende Belastungen f\u00fcr das Kalb untersucht. Ziel der vorliegenden Pilotstudie war, das Schmerzerlebnis der K\u00e4lber bei diesem Eingriff zu erfassen.<\/jats:p><jats:p>\n          Material und Methoden Im Rahmen einer Doppelblindstudie wurden 16 m\u00e4nnliche, 8\u201310 Wochen alte Fleckvieh- oder Fleckviehkreuzungsk\u00e4lber untersucht. Probanden der Gruppe A (Amputation) wurde an Tag 0 ein Gummiring 3 cm oberhalb der Schwanzspitze angelegt, bei Tieren der Gruppe K (Kontrolle) erfolgte an dieser Stelle ein Kontrollhandling. Nach dem Eingriff wurde mittels ELISA die Konzentration von Kortisol und Substanz P im Blutplasma untersucht sowie Verhaltens- und Aktivit\u00e4tsparameter anhand videogest\u00fctzter Verhaltensbeobachtung und Pedometerdaten erfasst.<\/jats:p><jats:p>\n          Ergebnisse Der Eingriff beeinflusste die Substanz-P-Konzentration nicht. Anders als in Gruppe A sank in Gruppe K die Kortisolkonzentration im Vergleich zum Basalwert ab. An Tag 0 zeigten K\u00e4lber der Gruppe A im Vergleich zu Tieren der Gruppe K eine h\u00f6here Schrittzahl, vermehrtes Schlagen mit dem Schwanz sowie h\u00e4ufigere Interaktionen des Kopfes mit Schwanz oder Hinterhand.<\/jats:p><jats:p>\n          Schlussfolgerung Eine h\u00f6here Schrittzahl nach Anbringen des Gummirings l\u00e4sst sich als Zeichen f\u00fcr Unruhe interpretieren, geh\u00e4uftes Schwanzschlagen und Benagen\/Belecken des Schwanzes als schmerzbedingtes Abwehrverhalten. In Kombination mit dem gleichbleibend hohen Kortisolspiegel sprechen diese Parameter f\u00fcr eine schmerzhafte Belastung der K\u00e4lber durch die Amputation.<\/jats:p><jats:p>\n          Klinische Relevanz Um die Inzidenz von Schwanzspitzennekrosen zu vermindern, sollte zun\u00e4chst eine tierschutzgerechte Verbesserung der Haltungsumwelt im Vordergrund stehen. Bei Durchf\u00fchrung der Amputation l\u00e4sst sich auf Grundlage dieser Studie die Gabe eines nicht steroidalen Antiphlogistikums vor Anlegen des Gummirings empfehlen, um die Schmerzbelastung f\u00fcr das Tier zu minimieren.<\/jats:p>","DOI":"10.1055\/a-1261-6346","type":"journal-article","created":{"date-parts":[[2020,10,20]],"date-time":"2020-10-20T22:36:51Z","timestamp":1603233411000},"page":"328-337","source":"Crossref","is-referenced-by-count":5,"title":["Verhaltensassoziierte
