Eine Erhebung zur Parasitenkontrolle auf biologisch wirtschaftenden Schaf- und Ziegenbetrieben in der Schweiz

Summary

To determine the current control measures for strointestinal nematodes (GIN) on Swiss organic small ruminant farms, a phone questionnaire was developed and conducted. The survey also aimed to assess the understanding and implementation of
possible alternative GIN control options. In total, 52 meat sheep and 58 dairy goat farm questionnaires were completed, and it was found that in general, farmers were aware of the potential benefit of an adequate grazing management to reduce GIN infection. However, practical realisation was often limiting. On average it was stated that adult meat sheep and dairy goats were drenched 1.5 and 1.3 times per animal and year, respectively, whilst lambs and kids were treated 1.6 and 1.3 times per animal and year, respectively. Sixteen percent of the interviewed organic goat farmers
and 10% of the organic meat sheep farmers stated that they have confirmed anthelmintic resistance on their properties.
