Abstract: Fifteen Yankasa rams, balanced for their weight, were used to evaluate the effects of feeding basal diet of Pterocarpus erinaceus forage supplemented with Sheabutter Fat (SBF) based concentrate diets on performance, nutrient digestibility and economic benefit. The rams were submitted to four supplemental diets containing: 0 g/kg SBF (control), 50 g/kg SBF and 100 g/kg SBF in a completely randomized design for 56 days. Average Daily Gain (ADG), intakes of Ether Extract (EE) and Crude Protein (CP), Feed Conversion Ratio (FCR), digestibility coefficients of EE and Organic Matter (OM), digestible OM, digestible and metabolizable energy concentrations and net benefit improved (p<0.05) with increasing levels of SBF supplementation. While forage intake was reduced (p<0.05) in SBF diets, the reverse was the case for the concentrate (p<0.05). Dry Matter (DM) intake and intake as the percentage of live weight, CP, OM and Crude Fibre (CF) intakes and CF digestibility were similar among the treatments. SBF diets improved (p<0.05) digestibilities of DM and CP compared to the control. OM intake was higher (p<0.05) in 50 g/kg SBF than in the control which compared with 100 g/kg SBF. Cost of feed consumed/sheep was lower (p<0.05) for 100 g/kg SBF compared to the control and 50 g/kg SBF. Feed cost/kg of mutton decreased (p<0.05) progressively from the control to 100 g/kg SBF. Differential and relative benefits were more (p<0.05) for 100 g/kg SBF than for 50 g/kg. 100 g/kg SBF supplementation improved the performance, nutrient digestibility and economic benefit.
