Chemical composition, digestibility and performance of Brachiaria decumbens at different ages of recovery
The objective of the study was to determine the chemical composition, digestibility and yield of Brachiaria decumbens at different regrowth ages. The times were; little rainy (January-April) and rainy (July-October). The treatments (regrowth ages: 30, 45, 60, 75, 90 and 105 days) were distributed in...

The times were; little rainy (January-April) and rainy (July-October). The treatments (regrowth ages: 30, 45, 60, 75, 90 and 105 days) were distributed in a randomized block design with four replications. The dry matter (DM) presented higher values (p≤0.01), at 60 days with 6.05 and 1.83 t DM ha-1 for the rainy and dry season. The crude protein (p≤0.01) in both periods was reflected at 30 days, 11.82% for the rainy season and 12.28% for the dry season. The digestibility showed the highest percentages (p≤0.001) at 30 days in rains and little rains, with 57.9 and 61.13%.

El objetivo del estudio fue determinar la composición química, digestibilidad y rendimiento de Brachiaria decumbens a diferentes edades de rebrote. Las epocas fueron; poco lluvioso (Enero-Abril) y lluvioso (Julio-Octubre). Los tratamientos (edades de rebrote: 30, 45, 60, 75, 90 y 105 días) se distribuyeron en un diseño de bloques al azar con cuatro réplicas. La materia seca (MS) presentó valores superiores (p≤0.01), a los 60 días con 6.05 y 1.83 t MS ha-1 para el lluvioso y poco lluvioso. La proteína bruta (p≤0.01) en ambos períodos se reflejó a los 30 días, 11.82 % para el lluvioso y 12.28 % para el poco lluvioso. La digestibilidad mostró los porcentajes mayores (p≤0.001) a los 30 días en lluvias y pocas lluvias, con 57.9 y 61.13%. La composición química, digestibilidad y rendimiento de Brachiaria decumbens fue influenciada de forma directa por las diferentes edades de rebrote, al aumentar la producción de la planta y disminuir su calidad. Se obtuvieron ecuaciones de regresión cuadráticas y cúbicas (coeficientes superiores a 0.72) que establecieron una estrecha relación con la edad y los indicadores del rendimiento, la composición química y digestibilidad.
