Abstract

An experiment was conducted to evaluate the nutritional and anti-nutritional characteristics of raw and  processed Mucuna sloanei meal, as well as their metabolisable energy. In the experiment some nutritional and anti-nutritional factors of the raw (RMS), boiled (BMS), toasted (TMS) and soakedand-boiled (SBMS) Mucuna sloanei meals and their metabolisable energy were assessed. Apparent metabolisable energy (AME) and true metabolisable energy (TME) of raw and processed meals were investigated via voluntary and force-feeding, respectively, using adult broiler birds (roosters), Mucuna sloanei and their respective diets were analyzed for proximate composition. The gross energy was determined using Adiabatic Bomb Calorimeter. In the  experiment SBMS caused significant (P<0.05) reductions in the anti-nutritional factors (L-Dopa=1.17%,  Tannin=0.15%, Trypsin inhibitor =0.11 Tiu/mg, phytate=0.26%). Soaked-and-boiled Mucuna sloanei (SBMS) gave lower crude protein value (28.58%). There were no significant (P>0.05) differences among the raw and processed forms for gross energy (GE) and AME while SBMS gave significantly (P<0.05) higher TME (2.85kcal/g) than all the others. SBMS gave the best value in terms of energy metabolism, anti-nutrient detoxification
