[Metaphylactic antibiotic treatment of footrot in sheep using Florfenicol]

A case report describes the metaphylactic antibiotic treatment of 520 sheep suffering from footrot (lameness prevalence > 60%) in late pregnancy (targeted selective treatment). Because of the lack of pharmaceuticals licensed for sheep and footrot in Germany in 2009, Florfenicol was used off label. Clinical recovery was observed a few days after a one shot application of florfenicol without any further treatment. The examination of all feet after weaning revealed no clinical symptoms in 96% of the sheep. Complete healing of almost all affected sheep was achieved. No transmission of footrot to lambs was noticed. Since the goal of the treatment was relief from pain and suffering under the particular conditions of late pregnancy and not a clinical study on efficacy no untreated control group was established for comparison. The suitability of the method for eliminating footrot in sheep flocks during the housing period in winter is discussed.
