Intoxicação espontânea e experimental por Eupatorium tremulum (Asteraceae) em bovinos

Abstract: Descreve-se a intoxicação natural e experimental por Eupatorium tremulum em bovinos. Um surto de intoxicação espontânea por esta planta foi diagnosticado no município de Lages, Santa Catarina. Em um lote de 19 bovinos, três morreram após a transferência para uma invernada aonde havia grande quantidade de E. tremulum. Os animais foram encontrados mortos, e dois foram necropsiados e coletado amostras de vísceras para exame histológico. Experimentalmente, folhas verdes de E. tremulum foram administradas a cinco b… Show more

“…weirii (marshy areas) and B. coridifolia (dry pastureland) differ 4,28 and this could help to differentiate between the 2 intoxications. Additionally, lymphoid necrosis is reportedly less severe in cases of B. coridifolia poisoning 28 and E. tremulum , 17 and does not occur in the poisoning caused by B. triplinervium . 16 Lesions in the forestomachs are much less severe in B. triplinervium poisoning 16 than in the poisonings caused by the other 3 plants.…”

“…16 Lesions in the forestomachs are much less severe in B. triplinervium poisoning 16 than in the poisonings caused by the other 3 plants. Larger amounts (20–30 g/kg/bw) of E. tremulum 17 and B. triplinervium 16 must be consumed to induce disease and death in cattle; this is translated in much lower mortality ratios for these 2 plants when compared to Baccharis spp. toxicosis.…”

“…Much of the inferences regarding Senecio species toxicity can be transposed to Eupatorium species because they belong to the same family and share similar habitats (These et al 2013). However, a much lower number of reports regarding animal intoxication from foraging species belonging to this genus are available, even though cattle (Camarão et al 1990;Lucioli et al 2007) and other ruminants are known to ingest members of this genus, both in Brazil and in contiguous countries (Riet-Correa & Medeiros 2001;Rymer 2008).…”

“…As lesões ruminais decorrentes da ingestão de soro de leite devem ser diferenciadas de outras doenças que se apresentem na forma de surto, com lesões principalmente no tubo digestivo, dentre elas, intoxicação por Eupatorium tremulum (Lucioli et al 2007); Baccharis coridifolia (Tokarnia & Döbereiner 1975, Barros 1993, Varaschin et al 1998, Rissi et al 2005; Baccharis megapotamica var. weirii e var.…”
