Sixteen West African dwarf bucks aged between 7 and 8 months with an average weight of 6.95kg were used to ascertain the effect of level of replacement (0, 25, 75, 100%) of soybean meal with Delonix regia seed meal on growth performance, nutrient intake and nutrient digestibility. The bucks were randomly assigned to four treatments, with four bucks per treatment in a completely randomized design. No significant (p<0.05) difference was observed in dry matter intake and crude protein intake across the dietary treatments. Dry matter intake ranged from 176.87 in T1 to 208.53g/day in T4. Crude protein intake ranged from 30.41 in T2 to 31.80g/day in T4. The crude fibre, ether extract and ash intakes were significant and followed similar pattern with crude protein. Significant difference (p<0.05) was observed in all the growth performance measured parameters across the treatments. Average daily weight gain of 30.71-78.10g/day was recorded with T3 recording the highest. Significant differences (p<0.05) were observed in all the digestibility parameters measured except for dry matter. Crude protein digestibility ranged from 76.50% in T4 to 84.89% in T3. Crude fibre digestibility ranged from 57.51% to 70.25% with T3 having the highest. It can be concluded from the results of this study that replacement of Delonix regia seed meal at 75% had no adverse effect on intake, nutrient digestibility and weight gain in West African dwarf bucks.
