L.  aHybanthus calceolaria poisoning in cattle.h[electronic resource]  c2014  aHybanthus calceolaria, also known as ?papaconha? or ?ipepacuanha,? is a herbaceous plant found in northeastern Brazil, which is often implicated by farmers as the cause of neurological signs in livestock grazing. Several poisoning outbreaks associated with the ingestion of this plant were observed in cattle in the municipalities of Colônia de Gurguéia in the state of Piauí and Sirinhaém in the state of Pernambuco, Brazil. The main clinical signs were ataxia, recumbency, and myokymia. No significant lesions were observed during necropsy or on histological examination. The disease was experimentally reproduced by the administration of 2 daily doses of 40 g/kg/body weight of the fresh green plant containing fruits. The plants without fruits were nontoxic, which is in accordance with the farmers? information, as it was stated that the poisoning only occurs when the plant is fruiting.  aAnimal production  aBovino  aIntoxicação  aProdução animal  aEnvenenamento  aHybanthus calceolaria  aIpepacuanha  aPapaconha  aPlantas tóxicas1 aNASCIMENTO, E.
