[case.gif] Case summaries
A goat breeder put his herd into a new pasture. Within 15 days, four animals had died; the remainder presented with colic and diarrhoea. Several animals had more pronounced symptoms such as salivation, tremor, and paddling movements of the legs. In addition, the milk production of the herd fell considerably. There were no characteristic lesions.
A detailed inspection of the land found only two toxic plants, silverweed (Potentilla anserina) and ground ivy. Poisoning by the former was discounted as the analytical laboratory found only ground ivy in the gastnc contents of the animals.
