Abstract

Summary

Objective: To evaluate the relative efficacy of a novel, commercially available disinfecting agent containing ≥ 15 to < 20 % glutaraldehyde in a hydro-colloid matrix (“EIMÜ Klauen Sprint^®”; Eimermacher, Nordwalde, Germany, Biozid-Desinfektionsmittel, BAuA Nr. N-57213) as a walkthrough footbath in order to treat digital dermatitis of dairy cattle. Material and methods: The study was conducted in a dairy farm located in northern Germany from June 1st, 2015 to September 5th, 2015. Eighty-eight cows were enrolled in this study. In both trials of the study, a walkthrough footbath was applied on five consecutive milking times per week. Trial 1 was a blinded, randomised and controlled intervention study. The therapy group (n = 40) received the novel glutaraldehyde product in a 2 % solution while the control group (n = 40) was led through a footbath containing pure water. Trial 2 was a longitudinal study to investigate the development of claw health over a longer time period regarding the use of the new footbath solution. In trial 2 the disinfecting footbath was applied to all trial cows (therapy and control group) of trial 1. The development of claw health and lameness was systematically monitored in the two groups on days 0, 9, 17, 29, 35 (trial 1) and days 42, 68, 94 (trial 2), respectively. The adjusted odds of digital dermatitis lesions (DDL) throughout the study were analysed by mixed logistic regression models. Results: The odds of DDL were 0.15 for the glutaraldehyde foot-bath group compared to the control group. Hence, the disinfecting footbath significantly reduced the DDL prevalence and increased the cure rate of DDL. However, no preventive effect on new digital dermatitis (DD) cases could be identified. Conclusion: The efficacy of the novel glutaraldehyde footbath was evaluated and it was concluded that “EIMÜ Klauen Sprint^®” was well tolerated over a longer period of time and might therefore be an effective tool to control DD. Clinical relevance: In future, „EIMÜ Klauen Sprint^®“ could be used within a Mortellaro sanitation concept and thereby might help to solve a major problem of dairy cattle farms.

Zusammenfassung

Ziel der Studie war, die Wirksamkeit eines neuen, kommerziell erhältlichen Desinfektionsmittels („EIMÜ Klauen Sprint^®“; Eimermacher, Nordwalde, Germany, Biozid-Desinfektionsmittel, BAuA Nr. N-57213) zu testen, das ≥ 15 bis < 20 % Glutaraldehyd in einer Hydrokolloidmatrix beinhaltet und als Klauenbad zur Behandlung von Klauengesundheitsstörungen bei Milchkühen eingesetzt wurde. Material und Methoden: Die Studie wurde vom 1. Juni 2015 bis zum 5. September 2015 in einem Betrieb in Norddeutschland an 88 Milchkühen durchgeführt. In zwei Versuchen wurde das Klauenbad zu fünf Melkzeiten pro Woche angewendet. Versuch 1 bestand aus einer geblindeten, randomisierten und überwachten Untersuchung. Die Versuchsgruppe (40 Tiere) erhielt eine Klauenbadbehandlung mit einer 2 %igen Lösung des neuartigen Produkts, während die Kontrolltiere (n = 48) durch ein ausschließlich Wasser enthaltendes Klauenbad geführt wurden. In Versuch 2, einer Longitudinalstudie, wurden alle Tiere der Versuchs- und der Kontrollgruppe aus Versuch 1 mit dem neuen Klauenbad behandelt und die Entwicklung der Klauengesundheit während einer längeren Behandlung überprüft. Die Entwicklung der Klauengesundheit und der Lahmheiten wurde in beiden Gruppen an Tag 0, 9, 17, 29, 35 (Versuch 1) und 42, 68, 94 (Versuch 2) systematisch überwacht. Zur Analyse der korrigierten Wahrscheinlichkeiten von Dermatitis-digitalis-Läsionen (DDL) im Studienverlauf dienten gemischte logistische Regressionsmodelle. Ergebnisse: Die Wahrscheinlichkeit für eine DDL war 0,15 in der Versuchsgruppe im Vergleich zur Kontrollgruppe. Das Klauenbad reduzierte die Prävalenz von DDL signifikant und erhöhte deren Heilung. Ein Effekt auf die Neuentstehung von Dermatitis Digitalis (DD) zeigte sich nicht. Schlussfolgerung: „EIMÜ Klauen Sprint^®“, als Klauenbad angewendet, stellte sich gut verträglich und effektiv in der Kontrolle von DD dar. Klinische Relevanz: Zukünftig könnte „EIMÜ Klauen Sprint^®“, im Rahmen eines Mortellaro-Sanierungskonzeptes, Anwendung finden und dazu beitragen, ein großes Problem milchviehhaltender Betriebe zu lösen.
