An experiment was carried out to investigate the apparent nutrient digestibility and nitrogen utilization of feed for West African Dwarf (WAD) sheep fed five selected plants in small ruminant research farm, Yaba College of Technology, Lagos. Twenty WAD sheep were subjected to five dietary treatments with four animals per treatment in a completely randomized design for an in vivo experiment that lasted for 84 days. The animals were fed Anacardium occidentale, Gmelina arborea, Mangifera indica and Gliricidia sepium leaves using Panicum maximum as a basal diet. Dry matter (DM) digestibility varied (p<0.05) between sheep fed Mangifera indica + Panicum maximum and Anacardium occidentale + Panicum maximum respectively. Crude protein digestibility was highest (p<0.05) in sheep fed Anacardium occidentale + Panicum maximum and lowest in sheep fed Mangifera indica + Panicum maximum. Nitrogen digestibility ranged from 79.64% in animals fed Panicum maximum (control) to 93.62% in animals fed Anacardium occidentale + Panicum maximum. Sheep fed Anacardium occidentale + Panicum maximum had highest (p<0.05) value (1.63 g/d) urinary nitrogen while the lowest value (0.65 g/d) was observed in animals fed Mangifera indica + Panicum maximum. Nitrogen absorbed had least value (2.36g/d) in animals fed the control diet whereas significant highest value was recorded in animals fed Anacardium occidentale + Panicum maximum (7.56g/d). The study concluded that sheep fed Anacardium occidentale supplemented with Panicum maximum had the higher values of nutrient digestibilities and nitrogen intake.
