%X this research evaluated, using the in situ technique, the dry matter and fiber fraction degradability of the mineir£¿o stylo (stylozanthes guianensis). the nylon bag method was used for the degradability assay, with two incubations in rumen-cannulated adult female cows. in each incubation, 25 samples of 7.0 g each were used. the samples were collected at 0, 6, 9, 12, 24, 36, 48, 72 and 96 hours. the experiment was conducted according to a randomized blocks design and data were submitted to analysis of variance. the maximum effective degradability was obtained in the 2% passage rate. for the 5% passage rate the mineir£¿o stylo showed effective degradation of 75.70% for dry matter, 59.01% for neutral detergent fiber and 76.81% for acid detergent fiber. the digestibility achieved by the dry matter and fibrous fraction from mineir£¿o was considered high. these results, coupled with the low lag time found reveal the forage potential of the cultivar.
