Abstract

The use of brewery by-products in cattle feed has grown in recent years as an excellent alternative for maintenance or increase in cattle productivity especially in Southeastern Brazil. Among the most employed by-products are malted barley waste and brewer's yeast, a liquid by-product that contains alcohol and is widely used in the State of Rio de Janeiro. Careless or incorrect use of these products, as well as inadequate storage, can cause ethanol poisoning, neurotoxicosis by Aspergillus clavatus, ruminal acidosis and botulism. This paper highlights the importance of these conditions as causes of severe economic losses to livestock, and provides support for the establishment of diagnosis, differential diagnosis and prophylaxis.
