| The occurrence of pharmaceuticals in the environment was frequently reported and possible adverse effects on non-target organisms are of increasing concern. The presence of veterinary drugs in manure may cause largely unknown ecotoxicological effects. Organic animal health management puts emphasis rather on prevention than on treatment. This could be an approach to develop a more sustainable production system. The current health situation in organic farming still requires veterinary drugs. Investigating the extent of the use and the toxic potential of pharmaceuticals could demonstrate that organic farming is the less polluting system. |

| Oak and Walnut are both of ethnoveterinary importance, especially for anthelmintic treatment of ruminants [1,2]. H2O and EtOH-water (1:1) extracts of oak and walnut foliage were used for phytochemical profiling and for in vitro assays with Caenorhabditis elegans and gastrointestinal nematodes (GIN). Oak extracts contained mainly tannins, walnut extracts were dominated by flavonoids. Oak EtOH extract caused significant lethal effects in adult C. elegans (LC50 1.5 mg/mL); motility of GIN L3 larvae was reduced by the EtOH extract but at substantially higher concentrations. Egg hatching was inhibited by both, the oak H2O and EtOH extract. In vivo: 42 lactating Alpine goats carrying natural GIN infections were allocated to 3 feeding groups: oak, walnut and... |
