Summary:The objetive of this study was to evaluate the ruminal fermentation characteristics of Bauhinia divaricata and Muntingia calabura foliages alone and combined with Pennisetum sp. Five treatments were evaluated: P = Pennisetum sp. (100%); Mc = M. calabura (100%); Bd = B. divaricata (100%); McP = M. calabura (30%)/Pennisetum sp. (70%), and BdP = B. divaricata (30%)/Pennisetum sp. (70%). The treatments with the highest in vitro dry matter degradability (DMS) were P, BdP, McP and Bd (> 50%) (P≤0.05). There were no significant differences (P> 0.05) in gas production (PG) among treatments Bd, BdP, McP and P; however, Mc produced 35% less gas (P≤0.05) than the other treatments. Conversely, Mc produced 153% more methane (CH4) than Bd (P≤0.05), being Bd and BdP the treatments with the lowest CH4 production. No significant differences (P> 0.05) were observed in volatile fatty acid (VFA) concentration, except for acetic acid between Mc and P with Bd, and isovaleric acid between Mc and Bd (P≤0.05). In conclusion, B. divaricata foliage decreased CH4 production and did not negatively affect other ruminal fermentation variables, thus representing a dietary alternative to reduce the ruminal methanogenesis of cattle in the tropics. El objetivo de este estudio fue evaluar las características de la fermentación ruminal de los follajes de Bauhinia divaricata y Muntingia calabura solos y combinados con Pennisetum sp. Se evaluaron cinco tratamientos: P=Pennisetum sp. (100%); Mc=M. calabura (100%); Bd= B. divaricata (100%); McP= M. calabura (30%)/Pennisetum sp. (70%), y BdP= B. divaricata (30%)/Pennisetum sp. (70%). Los tratamientos con la mayor degradabilidad in vitro de la materia seca (DMS) fueron P, BdP, McP y Bd (>50%) (P≤0.05). No hubo diferencias significativas (P>0.05) en la producción de gas (PG) entre los tratamientos Bd, BdP, McP y P; sin embargo, Mc produjo 35% menos gas (P≤0.05) que los demás tratamientos. Contrariamente, Mc produjo 153% más metano (CH4) que Bd (P≤0.05), siendo Bd y BdP los tratamientos con menor producción de CH4. No se observaron diferencias significativas (P>0.05) en la concentración de ácido grasos volátiles (AGV), excepto de ácido acético entre Mc y P con Bd, y de ácido isovalérico entre Mc y Bd (P≤0.05). En conclusión, el follaje de B. divaricata disminuyó la producción de CH4 y no afectó negativamente otras variables de fermentación ruminal, por lo que representa una alternativa alimenticia para reducir la metanogénesis ruminal de ganado en el trópico.
