Resumo: | Ruminal degradability of dry matter, neutral detergent fiber and acid detergent fiber of cultivars Stylozanthes guianensis (Mineirão) and Stylozanthes spp. (Campo Grande) were evaluated. Two incubations in rumen-fistulated adult bovine females were undertaken. Each incubation comprised of 25 samples of 7.0 g of each cultivar and samples were collected at 0, 6, 9, 12, 24, 36, 48, 72 and 96 hours after incubation. At a 5%/hour passage rate, Stylozanthes guianensis had 75.70, 59.01 and 76.81% effective degradability for dry matter, neutral detergent fiber and acid detergent fiber, respectively, whereas Stylozanthes spp. had 68.39, 51.93 and 58.89% for the same fractions. The lag time was different (P&lt;0.05) only for acid detergent fiber. Stylozanthes guianensis presented higher ruminal degradability in dry matter and fiber fraction when compared to those by Stylozanthes spp. The decision to adopt one or another cultivar depends on studies that take into account the cost of deployment and maintenance of leguminous cultivar and its assets.
