Resumo: The experiment was carried out being used four bovine cannulated at rumen. Corn silage and chopped sugar cane, treated with 2% NaOH were furnished to the animals during the experiment. Four treatments consisting of sugar cane treated with 0, 2, 4 and 6% NaOH were evaluated by ruminal incubation using nylon bags. Dry matter (DM), organic matter (OM), neutral detergent fiber (NDF), acid detergent fiber (ADF), cellulose (CELL) and hemicellulose (HEM) disappearance were evaluated in 0, 6, 12, 24, 48, 72, 96 and 144 hours of ruminal incubation. Potencial degradability (PD) and effective degradability (ED) were determinated using the model suggested by Orskov & Mc Donald (1979), accepting a passage rate of 5%/hour. It was observed highest (P < 0.05) PD and ED, respectively, for DM (62,01% and 49,39%), OM (62,98% and 49,10%), NDF (57,61% and 34,75%), ADF (55,67% and 35,25%), CEL (64,89% and 36,73%) and HEM (61,44% and 35,72%), in sugar cane treated with 6% NaOH. It can be concluded that the chemical treatment of the sugar cane with 6% NaOH promoted highest potential degradability of the dry matter, organic matter and fibrous fraction. PD and ED values of the fibrous fraction of the sugar cane treated with 6% NaOH, justify the use of this treatment in conditions in that these were used.

Durante o experimento, os animais receberam uma dieta à base de silagem de milho e cana-de-açúcar picada e tratada com 2% de NaOH. Foram avaliados quatro tratamentos à base de cana-de-açúcar com diferentes níveis de NaOH (0, 2, 4 e 6%) incubados no rúmen usando-se sacos de náilon. Determinou-se o desaparecimento da matéria seca (MS), matéria orgânica (MO), fibra em detergente neutro (FDN), fibra em detergente ácido (FDA), celulose (CEL) e hemicelulose (HEM) em 0; 6; 12; 24; 48; 72; 96 e 144 horas de incubações no rúmen. As degradabilidades potencial (DP) e efetiva (DE) foram determinadas segundo o modelo proposto por Orskov & McDonald (1979) a uma taxa de passagem de 5%/h. Dentro dos tempos de incubação, houve maior desaparecimento de MS, MO, FDN, FDA, CEL e HEM. para o tratamento com 6% de NaOH. Observou-se maior (p < 0,05) DP e DE, respectivamente, para MS (62,01% e 49,39%), MO (62,98% e 49,10%), FDN (57,61% e 34,75%), FDA (55,67% e 35,25%), CEL (64,89% e 36,73%) e HEM (61,44% e 35,72%), da cana-de-açúcar tratada com 6% de NaOH. Pode-se concluir que o tratamento químico da cana-de-açúcar com 6% de NaOH promoveu maior degradabilidade potencial e efetiva da MS, MO e da fração fibrosa. Os valores de DP e DE da fração fibrosa da cana de açúcar tratada com 6% de NaOH, justificam a utilização deste tratamento nas condições em que estas foram utilizadas.UEL2007-08-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/299310.5433/1679-0359.2007v28n3p503Semina: Ciências Agrárias; Vol. 28 No. 3 (2007); 503-512Semina: Ciências Agrárias; v. 28 n. 3 (2007); 503-5121679-03591676-546Xreponame:Semina.
