Leguminous browse forages ensiled with cassava peel residues are increasingly used in ruminant feeding because of their high crude protein content, digestible energy, and overall nutritive value. Therefore, an 84-day feeding trial was carried out to investigate the effects of incorporating Gliricidia sepium (GS), Ficus thonningii (FT), and Gmelina arborea (GA) forages with cassava peel–maize residue (CPR) silage on nutrient intake and digestibility in West African Dwarf (WAD) bucks. A total of sixteen growing WAD bucks aged 6–9 months, with body weights ranging from 6.0 to 10.0 kg, were randomly assigned to four dietary treatments in a completely randomized design, with four animals per treatment and two animals per replicate. The experimental diets consisted of T1 (100% CPR), T2 (CPR70GS30), T3 (CPR70FT30), and T4 (CPR70GA30). Animals were fed the diets at 3% of their body weight and supplemented daily with 200 g concentrate. Results showed significant differences (p < 0.05) among treatments for both nutrient intake and digestibility parameters. The highest dry matter intake (363.28 g/day) was recorded in bucks fed T2, whereas the lowest value (342.81 g/day) occurred in animals receiving T4. Crude protein intake (132.14 g/day) was highest in bucks fed T3, while the lowest value (23.87 g/day) was observed in animals fed T1. Similarly, the greatest crude fibre intake (91.45 g/day) occurred in T1, whereas the lowest (74.08 g/day) was recorded in T2. Ash intake was highest in T4 (16.69 g/day) and lowest in T3 (14.42 g/day), while nitrogen-free extract intake was highest in T1 (168.42 g/day) and lowest in T2 (145.93 g/day). In terms of digestibility, bucks receiving the T3 diet showed the highest dry matter digestibility (46.89%), whereas the lowest value (41.78%) was observed in T4. Crude protein digestibility was lowest in T1 (39.75%) and highest in T3 (62.73%). The highest crude fibre digestibility (50.06%) was recorded in T4, while the lowest value (34.07%) occurred in T1. The results indicate that incorporating Ficus thonningii with cassava peel residues at a 70:30 ratio, alongside concentrate supplementation, can improve nutrient intake and digestibility in growing WAD bucks.
