An experiment was conducted to evaluate dry matter intake, total tract digestibility and nitrogen balance by red Sokoto bucks fed varying levels of Gmelina arborea leaf meal (GLM). Diet 1 devoid of GLM served as the control. Diets 2, 3 and 4 had GLM supplemented at 10, 20, 30% levels, respectively. A 4X4 Latin square design arrangement was employed for the study that lasted for 21 days. Animals fed 10 and 20% Gmelina arborea diets had statistically (P>0.05) similar dry matter intake (442.20 and 427.80g/day, respectively) and were significantly higher (P>0.05) than values obtained for animals fed 30% level of GLM inclusion. Organic matter intake (OMI) were statistically similar and higher (P<0.05) at 0 and 10% inclusion levels of GLM, while 20 and 30% inclusion level had the lowest (389.71 and 388.52g/d). Crude protein intake (CPI) at 10 and 20% GLM inclusion levels were similar and significantly (P<0.05) higher, followed by control and the least was observed in 30% GLM inclusion level. Dry matter digestibility (DMD) was significantly (P<0.05) different across the dietary treatments, with 10% inclusion level being higher, followed by 20, and 30%. retention differ (P<0.05) significantly, at 10% GLM inclusion had (22.93 g/day), followed by the control (18.88g/day), which significantly declined with increasing level of GLM (18.74, 12.12 g/day) at 20 and 30 % inclusion level, respectively. observed was significantly (P<0.05) different, diet with 10% GLM had high observed (39.97g/day) and decreasing at 20 and 30% GLM (36.86 and 37.96g/day). retention as percent of intake followed similar pattern. From the result of this study, it can be concluded that inclusion of GLM at 10% had no adverse effect on intake and nutrient digestibility in goats
