An outbreak of ethanol poisoning that affected a dairy cattle herd fed with the brewery by-product known as malt bagasse, wet brewery residue, malted barley waste or “barley”. The outbreak began about 24 hours after a new product of the by-product was offered to cattle that had an alcoholic odor. Chromatographic and microbiological analysis of this by-product sample confirmed the presence of ethanol and Saccharomyces spp., respectively, indicating the addition of another by-product brewery, brewer’s yeast or yeast. The main clinical signs observed were diarrhea, salivation, staggering gait and decubitus. Morbidity was 12.2% (5/41) and mortality was 2.4% (1/41). A cow that died after a 3-day of clinical course was necropsied. No significant macroscopic lesions were observed, but in the histopathology, there was acute, multifocal, moderate necrosupurative rumenitis with secondary bacterial and fungal colonization, indicating concomitant ruminal acidosis. In the chromatographic analysis of samples of rumen and liver contents of this bovine, variable amounts of ethanol were detected. The data from the present study indicate that the possibility of ethanol intoxication should be considered in cattle with neurological and digestive signs fed with RUC when added to brewer’s yeast. |
