Resumo: This study was carried out in order to evaluate the effects of two sorghum varieties (high and low tannin) and levels of methionine (0.0%, 0.60% and 0.90%) in Nile tilapia, Oreochromis niloticus L. (Perciformes, Cichlidae), diets on apparent digestibility of dry matter, crude protein and crude energy. 100 fish were distributed in ten aquarium (250L). After a climatization period of three days, representative samples of feces were obtained daily until reach six replicates each treatment. The apparent digestibility coefficient was calculated based in chemical analysis of diets and feces to determine chemical composition and chromic oxide. It was concluded that for Nile tilapia the low tannin sorghum has similar apparent digestibility to corn and that the high tannin variety has significant lower apparent digestibility than corn and low tannin. The supplementation of methionine it is not enough to control the anti-nutritional effect of tannin.

(Perciformes, Cichlidae). Foi avaliada a digestibilidade aparente da matéria seca, proteína bruta e energia bruta. Empregaram-se 100 peixes distribuídos em 10 grupos, os quais receberam rações contendo sorgo alto e baixo tanino e 0,0%; 0,60% e 0,90% de metionina. Após um período de aclimação de três dias, foram colhidas amostras representativas das fezes produzidas diariamente até completar seis repetições de cada tratamento. A partir das análises químicas das rações e das fezes e utilizando-se o óxido de crômio como marcador inerte, foram calculados os coeficientes de digestibilidade aparente. Pode-se concluir que para tilápia do Nilo, o sorgo variedade baixo tanino apresenta coeficientes de digestibilidade aparente que podem ser considerados semelhantes aos do milho; que a variedade alto tanino apresenta coeficientes de digestibilidade aparente significativamente inferiores aos do milho e da variedade baixo tanino e; que a suplementação de metionina não é suficiente para controlar a ação antinutricional do tanino.Editora da Universidade Estadual de Maringá2008-04-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/234710.4025/actascianimsci.v24i0.2347Acta Scientiarum.
