  Se midió la digestibilidad y consumo voluntario de Brachiaria humidicola CIAT 679, bajo tres cargas equivalentes a 1.9, 2.9 y 5.7 animales/ha, utilizando como marcadores papel óxido de cromio y fibra neutra indigerible. El consumo voluntario fue mayor (P < 0.05) en la carga de 2.9 an/ha (59.8 g MS/W°*75/dia) que en la de 5.71 an/ha (44.3 g MS/W0,7S/dia, pero sim ¡lar al consumo déla carga de 1.9 an/ha (50.4 g MS/W0,75/dia). La diges- tibilidad del forraje (52.1 o/o) no varió significativamente con carga animal o fase de medida.

  The digestibility and voluntary consumption of Brachiaria humidicola CIAT 679 under three diferent pasturing pressure or equivalent charges of 1.9, 2.9 and 5.7 an/ha was measured; using cro- mium oxide paper and digestible neutral fiber as indicators. The voluntary consumption was greater (P< 0.05) in the charge of 2.9 an/ha (59.8g D.M/ W°*75/day) compared with the charge of 5.7 an/ha (44.3 g jDM/W°-7S/day); but similar to the consumption of the charge of 1.9 an/ha (50.4 g DMA/V0,75/ day). The consumption in phase I (583 gDM/V^/day) was greater (P< 0.05) than phase II (44.1 g DM/W0,7S/day). The digestibility of forage (52.1 o/o) did not vary significantly with pasture preasure of measurement phase.
