| English abstract | Two outbreaks of spontaneous poisoning in cattle by Phalaris angusta Nees ex Trin.("aveia louca", "aveia de sangue") are reported in cattle. The outbreaks occurred in the State of Santa Catarina, Brazil, during the winters of 1993 and 1996. In both outbreaks the animals were held in paddocks where P. angusta was a prevalent forage. Clinical signs in affected cattle included generalized tremors, alertness, hypermetria, ataxia and convulsions. Gross lesions were restricted to the brain and consisted of gray to greenish discoloration in the thalamus and mesencephalon. The disease was experimentally reproduced in cattle by administration of P. angusta |

Nos dois surtos os animais estavam lotados em piquetes onde P. angusta era a planta dominante. Os sinais clínicos incluíam tremores generalizados, olhar atento, hipermetria, ataxia e convulsões. Alterações macroscópicas eram restritas ao encéfalo e se caracterizavam por coloração cinza-esverdeada no tálamo e mesencéfalo. A doença foi reproduzida experimentalmente em bovinos pela administração de P. angusta |
