Short description (German)	Die aktuell am häufigsten eingesetzten Desinfektionsmittel zur Bekämpfung der Moderhinke in der Schweiz zei-gen massive unerwünschte Wirkungen (Formalin ist kanzerogen; CuSO4 und ZnSO4 sind stark umweltbelastend). In Projekt 1.18.02 werden aktuell verschiedene alternative Desinfektionsmittel zur Bekämpfung der Moderhinke in Versuchen in in-vitro und ex-vivo getestet. Resultate der in-vitro Untersuchungen sind vorliegend und diejenigen der ex-vivo Untersuchungen werden auf Ende Mai 2019 erwartet. In-vitro hat Desintec Hoofcare Special D (DHSD) eine gute Wirkung gezeigt. Die Ziele der hier skizzierten Studie sind: Teil 1: Feldvalidierung von DHSD als Klauenbadlösung zur vollständigen Elimination von virulenten Stämmen von D. nodosus aus maximal 26 Schweizer Schafherden mit klinisch manifester Moderhinke. Teil 2: Bestimmung der mit der Bekämpfung einher-gehenden Kosten auf Herdenebene. Die Resultate dieser Studie werden eine der Grundlagen bilden für die For-mulierung der Empfehlungen des BLVs zur praktischen Umsetzung des geplanten Schweiz-weiten Moderhinke Bekämpfungsprogramms.
Short description (English)	The most frequently used disinfectants for therapy and control of ovine footrot in Switzerland are either cancero-genic (formaldehyde) or cause environmental pollution (CuSO4 and ZnSO4). Alternatives to these disinfectants are currently identified within the frame of the in-vitro and ex-vivo project 1.18.02. In-vitro, it was shown that Des-intec Hoofcare special D (DHSD) was effective in reducing viable D. nodosus (DN) by > 105. But in-vivo field data, using DSHD, is currently not available. The main goals of this study are to complete this knowledge gap by com-paring the efficacy and practical suitability of DHSD for its use in the planned Swiss footrot control program (part 1) and to evaluate the costs for complete elimination of virulent DN from the respective herds (part 2). For this purpose, up to 26 herds will be treated until completely sanitized (negative for virulent strains of DN). Results of this study can be used by the Swiss federal food safety and veterinary office (FSVO) to recommend measures for the practical implementation of the nationwide Swiss footrot control program.
Project aims (English)	- Part I: To compare under field conditions in up to 26 herds the efficacy and practical suitability of the new disin-fectant solution DHSD for its use in the planned Swiss footrot control program (in-vivo proof of concept study). - Part II: To evaluate the costs and investment of labour for complete elimination of footrot from the respective herds on herd level.
