Resumo
O tema abordado neste trabalho incide sobre a intoxicação por taninos dos bovinos, que ocorre após a ingestão de um elevado número de bolotas, levando à perda anual de um elevado número de animais, e consequentemente com perdas económicas relevantes junto do produtor. Uma vez que o tratamento desta doença é bastante complexo e encontra-se pouco descrito, o objectivo deste trabalho é contribuir para um melhor esclarecimento sobre a mesma, bem como, determinar a taxa de sucesso dos diferentes tratamentos. Foram realizados cinco tratamentos diferentes, numa amostra de trinta e cinco animais afectados, pertencentes a uma população de 440 animais, e foram determinadas as taxas de mortalidade e morbilidade. Níveis sanguíneos de ureia foram determinados em alguns dos animais afectados. Foi realizada a comparação da taxa de sucesso dos tratamentos e relacionada com os sinais clínicos apresentados. Os resultados do trabalho comprovaram que esta doença tem níveis de mortalidade e morbilidade significativos. O tratamento pode ser complexo e dispendioso, e é aplicado apenas a nível sintomatológico. Deste modo, concluiu-se que, em relação aos tratamentos efectuados, aquele que obteve a maior taxa de sucesso baseou-se na administração de Biorúmen®, tendo atingido uma taxa de 47%, em animais com sintomatologia ligeira, e a segunda melhor taxa de sucesso foi obtida com Biorúmen®, Sulfato de Magnésio, Indigest® e Diurizone®, em animais com sintomatologia severa.
This work addresses the cattle poisoning by tannins, an event that occurs after the ingestion of a large number of acorns, potentially leading to the loss of a large number of animals, and consequently carrying significant economic losses to the producer. Since this disease’s treatment is highly complex and is not well documented in the literature, the aim of this work is to contribute for a better clarification about this topic, as well as determine the success rate of the different treatments. Five different treatments were carried out in this study, on a sample of thirty-five infected animals out of a population of 440 animals, and the respective mortality and morbidity rates were calculated. Urea blood levels were determined in some of the affected animals. A comparison of the treatments’ successful rate was performed and related to the clinical signs of the disease. The results obtained in the work proved that this disease has significant mortality and morbidity levels. The treatment can be complex and expensive and administered only at a symptomatic level. Thus, it was concluded that, amongst the treatments carried out, the one with the highest success rate was the administration of Biorúmen®, reaching a rate of 47%. in animals with mild clinical signs, and second highest success rate of 40% was a combination of Biorúmen®, Magnesium Sulphate, Indigest® and Diurizone® in animals with severe clinical signs.
