No. of bitstreams: 1 PGCA15MA153.pdf: 768844 bytes, checksum: 09e919bb447b4491effdae453e00ced9 (MD5) Previous issue date: 2015-02-20 / Conselho Nacional de Desenvolvimento Científico e Tecnológico / Tifton 68 (Cynodon nlemfuensis Vanderyst) is a grass cultivated in southern Brazil and it causes peracute clinical manifestations of dyspnea, swallowing difficulty, muscle tremors, bloat and recumbency in cattle. After starting the first clinical signs, death occurs quickly. Gross and microscopic lesions were not observed. The present study describes the epidemiological, clinical and lesional spontaneous tifton 68 poisoning that occurred in Rio do Sul, Pouso Redondo, Taió and Rio do Campo, in Santa Catarina State. Data were obtained through information from Animal Pathology Laboratory, Centro de Ciências Agroveterinárias (LAPA / CAV) archives. Experimentally was performed the hydrocyanic acid concentration in fresh and dry leaves and treatment with specific antidote solution. The disease was experimentally reproduced with the administration of tifton 68 green leaves for two cattle in doses starting of 10.3 g/kg. The cyanogenic poisoning was confirmed by the immediate response to sodium thiosulfate and sodium nitrite intravenous treatment. Tifton 68 green leaves samples had positive response to picric acid paper test, with mild reaction, turning orange in color. Dried tifton 68 leaves showed no toxicity even at high doses (18 and 27 g/kg) being safe for cattle consumption / Tifton 68 (Cynodon nlemfuensis Vanderyst) é uma gramínea cultivada na região sul do Brasil e é responsável por manifestações clínicas superagudas de dispneia, dificuldade de deglutição, tremores musculares, timpanismo e decúbito em bovinos. A morte ocorre rapidamente após o inicio dos primeiros sinais e não são encontradas alterações macro e microscópicas significativas. O presente estudo descreve os aspectos epidemiológicos, clínicos e lesionais da intoxicação espontânea por tifton 68 que ocorreu nos municípios de Rio do Sul, Pouso Redondo, Taió e Rio do Campo, estado de Santa Catarina, registrados no Laboratório de Patologia Animal do Centro de Ciências Agroveterinárias (LAPA/CAV). Experimentalmente foram avaliados a concentração de ácido cianídrico nas folhas verdes e secas dessa planta e o uso de solução antídoto específica. A reprodução experimental consistiu na administração de folhas verdes de tifton 68 para dois bovinos com doses a partir de 10,3 g/kg. O quadro de intoxicação cianogênica foi confirmado pela imediata resposta ao tratamento endovenoso com tiossulfato de sódio e nitrito de sódio. As amostras da planta verde forneceram resposta positiva ao teste do papel picro-sódico. O feno de tifton 68 não demonstrou qualquer toxicidade, mesmo em doses maiores (18 e 27 g/kg), sendo seguro para a alimentação de bovinos
