The goal of this work was to evaluate the effect of three strains of yeast Saccharomyces cerevisiae (Yea Sacc 1026 -Allthech  , Biosaf SC-47 -Lesaffre  e BioSynergy -Kraft  ), in their respective commercial forms, on liquid phase outflow rate, ruminal volume and in situ degradability for the dry matter, cellulose and hemicellulose of the sugar cane. For this, four ruminal canuladed buffaloes of the Mediterranean breed were used and fed with a composed diet by 83 % of sugar cane and 17 % of

The four treatments A, B, K and T, with no yeast addition, were added directly into rumen of each animal, in all experimental periods. During the different periods, samples of ruminal content were colleted for estimate liquid phase outflow rate and ruminal volume, and conducted in situ degradability. For liquid phase outflow rate and ruminal volume, no significant differences were observed among the treatments studied. However, in situ degradability showed significant differences among the A, B and K treatments in relation to T (control).
