Previous issue date: 2012-08-31 / Funda??o Carlos Chagas Filho de Amparo ? Pesquisa do Estado do RJ - FAPERJ / Considering the practice of using liquid alcoholic yeast (beer yeast) - a byproduct of the
brewery industry - for animal feed on some farms in the southern Fluminense region of
Brazil, this study was made to establish the safety margin and the clinic-pathological picture
of the intoxication characterized mainly by staggering gait, trips and falls; furthermore, to
suggest preventive measures that could avoid or minimize this type of alcoholic intoxication
in sheep and pigs. It was seen that the clinic-pathologic picture of the experimental
intoxication by beer yeast in sheep, and the natural and experimental intoxication in pigs, is
similar to that observed in other animal species poisoned by ethanol, or in cattle by beer yeast.
Concentrations of 3.8 and 8.875mL/kg of ethanol contained in the yeast, caused respectively
mild to moderate clinical signs and severe ones in sheep. As prophylactic measures are
suggested (1) appropriated dilution of beer yeast in water or with beer yeast already stored on
the farm (old yeast), (2) beer yeast administration proportionally to animal weight/size, (3)
continuous administration without interruption, providing other food is given, as soybean or
corn meal, with water ad libitum. It was concluded that despite beer yeast is increasingly used
for sheep, pigs and cattle on farms in southern Rio de Janeiro state - since many farmers apply
one or more prophylactic measure suggested here - ethanol intoxication through beer yeast is
uncommon and death rarely occurs; so, the yeast could be used, providing the prophylactic
measures are observed. / Considerando a pr?tica de utilizar ?levedo? l?quido (alco?lico) (LC) - subproduto da ind?stria
cervejeira - na alimenta??o de animais, em alguns estabelecimentos da Regi?o Sul
Fluminense, esse estudo foi realizado para estabelecer as margens de seguran?a e o quadro
cl?nico-patol?gico caracterizado principalmente por andar cambaleante, trope?os e quedas;
bem como sugerir medidas profil?ticas que impe?am ou minimizem esse tipo de intoxica??o
alco?lica para ovinos e su?nos. Verificou-se que o quadro cl?nico-patol?gico na intoxica??o
experimental em ovinos e nas intoxica??es natural e experimental em su?nos, ? semelhante ao
observado em outras esp?cies intoxicadas por etanol ou em bovinos pelo LC. Concentra??es
de 3,8 e 8,875mL/kg de etanol contido no LC, causaram quadros cl?nicos de leve a moderado
e grave em ovinos, respectivamente. Como medidas profil?ticas sugere-se: dilui??o adequada
do LC com ?gua, soro de leite ou com o LC j? estocado na propriedade (LC antigo);
administra??o do LC proporcional ao peso/tamanho dos animais, administra??o cont?nua, sem
interrup??es, disponibilizar outro alimento no cocho, como farelo de soja ou fub? de milho e
?gua ? vontade. Conclui-se que apesar do ?levedo de cerveja? ser cada vez mais utilizado nas
propriedades criadoras de ovinos, su?nos e bovinos, no sul do Estado do Rio de Janeiro j? que,
muitos propriet?rios aplicam uma ou mais medidas profil?ticas aqui sugeridas, as intoxica??es
pelo etanol, contido no LC s?o pouco frequentes e raramente ocorrem mortes, de forma que
esse produto deve ser utilizado, desde que as medidas profil?ticas sejam observadas
