    The effect of processing methods on the chemical composition of Bauhinia monandra seed meal as a feed ingredient in the diets of ruminants was assessed in this study. Seeds of Bauhinia monandra were subjected to processing methods [Raw (T1), autoclave for 20 mins (T2), autoclave for 30 mins (T3), one stage cooking (T4), two-stage cooking (T5) and roasting (T6)]. The seeds were assessed for their chemical composition, antinutrients and mineral contents. T4 (one-stage cooking) had the highest crude protein levels of 31.3 %. T2 and T4 had the lowest fibre levels of 4.71 % and 4.67 % respectively. Antinutritional factors were significantly (P<0.01) affected by processing methods with a reduction in the antinutrient concentration. Autoclaving for 30 min had the highest reduction effect on alkaloid, tannin, saponin, glycoside and stachyose. Manganese was significantly (P<0.01) the highest and similar in the seed meals subjected to one-stage and two-stage cooking. Values of Mn in the unprocessed seed meals were significantly (P<0.01) lowest. The values of Fe (ppm) in seed meals ranged from 1.9010 in T1 – 6.8275 (T3). Autoclaving for 30 minutes significantly (P<0.01) increased the Fe contents of seed meals. Values for Cu and Zn were significantly highest (P<0.01) in T3. Zinc value was lowest in the unprocessed B. monandra seed meals. Calcium values ranged from 52.97 mg/l in T4 to 74.45 mg/l in T2. Magnesium levels were significantly highest in T6 and lowest (P<0.01) in T3. Seeds cooked twice gave the highest (P<0.01) value for Phosphorus. It is concluded that two-stage cooking of seeds appears to improve their chemical composition, however anti-nutritive contents of seeds were better reduced by autoclaving for 30 minutes. Bauhinia monandra seedmeal may serve as one of the ingredients for compounding livestock diets in the Nigerian feed mill industry based on the results on its chemical composition from this study.
