Ensilage potential and nutritional value of Columbus grass (Sorghum almum Parodi) at different phenology and storage duration in the derived savanna zone of Nigeria

Insufficient forage supply from natural rangelands during the dry season hampers ruminants' performance in the derived savanna zone of Nigeria. Therefore, to provide alternative feed resources, we evaluated silage potential of Columbus grass (Sorghum almum Parodi) at boot, dough and maturity st...

Zusammenfassung:	Insufficient forage supply from natural rangelands during the dry season hampers ruminants' performance in the derived savanna zone of Nigeria. Therefore, to provide alternative feed resources, we evaluated silage potential of Columbus grass (Sorghum almum Parodi) at boot, dough and maturity stages for 4‐, 8‐, 12‐ and 16‐week ensiling durations, in a 3 × 4 factorial experiment. The dry matter yield (DMY) was determined at each harvest stage, and the forages were subsequently ensiled. The results revealed that the DMY of S. almum at maturity was 8.98% and 18.67% higher than at dough and boot stages, respectively (p
