Ruminant production in the tropics is challenged by forage scarcity in the dry season. The conservation of forages particularly as silage can bridge this gap. This study assessed silage quality and nutrient digestibility of Megathyrsus maximus ensiled with varying levels of Gmelina arborea leaves (GAL) as dry season feed for West African Dwarf (WAD) sheep. Different mixtures of Megathyrsus maximus and Gmelina arborea leaves (GAL) were ensiled and designated as follows: T1: 100% Megathyrsus maximus; T2:75% Megathyrsus maximus + 25% GAL; T3: 50% Megathyrsus maximus + 50% GAL.; T4: 25% Megathyrsus maximus + 75% GAL; T5:100% GAL. Silage characteristics and chemical composition were investigated. Fifteen WAD sheep were used in the digestibility trial. Result revealed pH (4.6-5.1), 26.55% - 31.48% dry matter (DM), 10.93 – 15.88% crude protein (CP), 60.58 – 63.18% Neutral detergent fiber (NDF), 32.72 – 38.75% Acid detergent fiber (ADF), 17.37 – 19.50% Acid detergent lignin (ADL). The order of DM and CP digestibility coefficient of silage diet by WAD sheep is T2, T1, T3, T4 and T5. Megathyrsus maximus ensiled with varying levels of GAL holds potentials as dry season feed for ruminants showing better quality and digestility by WAD sheep as GAL increased in the diets.
