description The aim of this study was to determine the effect of modified glucomannan adsorbent (ADS) on the clinical, hematological and ruminal parameters in sheep subjected to diets containing aflatoxins (AFLA). Twenty two crossbred ewes (Corriedale vs Texel), aging 18 months were separated into four groups according to the addition of AFLA (1,5 PPM) or ADS (2 PPM) in the concentrate portion of the diet: animals receiving AFLA in the diet (AFLA; n=6); animals receiving AFLA and ADS in the diet (AFLA/ADS; n=6); animals receiving ADS in the diet (n=5) and control group, without addition of the ADS or AFLA in the diet (CONTROL; n=5). The diets were supplied during 42 days. Ruminal fluid was collected and analysed every seven days and the clinical evaluations (clinical examination, urinalysis, and hemogram) every 10 days. The addition of adsorbent increased the plasmatic concentration of eosinophiles. Clinical and ruminal parameters were not affected by the presence of adsorbent or aflatoxin into the diet. The modified glucomannan adsorbent influenced the leukocyte response of sheep, but no effect on ruminal function and clinical parameters. O objetivo deste estudo foi determinar o efeito do adsorvente (ADS) glucomanano modificado sobre parâmetros clínicos, hematológicos e ruminais de ovinos submetidos a dietas contendo aflatoxina (AFLA). Foram utilizadas 22 ovelhas mestiças (Corriedale e Texel), com 18 meses de idade. Os animais foram divididos em quatro grupos, de acordo com a adição de AFLA (1,5 PPM) ou ADS (2 PPM) na fração concentrada da dieta: animais recebendo AFLA na dieta (AFLA; n=6); animais recebendo AFLA e ADS na dieta (AFLA/ADS; n=6); animais recebendo ADS na dieta (ADS; n=5) e grupo controle, sem adição de ADS ou AFLA na dieta (CONTROLE; n=5). As dietas foram fornecidas por um período de 42 dias. Foram realizadas coletas de fluido ruminal a cada sete dias e avaliações clínicas (exame físico geral, urinálise e hemograma) a cada 10 dias. Quanto ao perfil leucocitário, a suplementação com adsorvente aumentou a concentração plasmática de eosinófilos. Os demais parâmetros clínicos e ruminais não foram influenciados pela presença do adsorvente ou da aflatoxina na dieta. Assim, o adsorvente glucomanano modificado influenciou a resposta leucocitária de ovinos, porém sem efeito na função ruminal e nos parâmetros clínicos avaliados.
