摘要：Lablab purpureus (L) sweet was origin planted on east java province, Indonesia. The native name is komak beans. It has high protein (30% -33%), but the inclusion is limited caused by anti-nutrition factors such as tannin, phytic acid, and anti-trypsin. Anti-nutrition substances interfere with metabolism and protein synthesis in intestinal tract. Komak beans were processed with high pressure steam (2 atm; 121 0C; 20 min) and called Komak Beans Meal (KBM). This study focused on replacing Soybeans Meal (SBM) based diet using uplift level until totally replaced with KBM. The study designated for 100 birds one-day old Cobb strain. Raising period was 5 weeks. The treatments were: Control (Basal diet); 25 % KBM replacement; 50 % KBM replacement; 75 % KBM replacement and 100 % KBM replacement. Data were analyzed using analysis of variance (ANOVA). The results showed that 25% KBM replacement was not significantly different with control and could increase 1.04 % feed consumption; 1.23 % body weights gain, 0.97 % production index and decreased feed conversion rate (0.73 %). High pressure steam KBM process had been effective in decreasing anti-nutrition effect and didn’t cause abnormalities on broiler production performance. It could improve the broiler production performance at level of 25% KBM inclusion replacement.
