    In Uganda, the price of maize as the main source of energy in poultry feed is prohibitive due to its scarcity and competitiveness. Therefore, research is required to study the nutritional value of alternative energy feedstuffs such as Java plum (Syzygium cumini) beans (JPB). Chemical analysis and one feeding trial were conducted to assess the nutritional value of boiled Java plum beans (BJPB) in broiler chick diets. In the feeding trial, boiled Java plum bean meal (BJPBM) substituted maize meal (MM) by 0, 25, 50, 75 and 100% in broiler starter diets. The BJPB had dry matter (DM) content of 85.0±2.03%, nitrogen free extract (NFE) of 72.9±1.95%, calculated metabolisable energy (ME) of 13.3±0.25MJ/kg, crude protein (CP) of 4.23±0.48%, ether extract (EE) of 1.05±0.17%, crude fibre (CF) of 5.06±0.72%, ash of 1.75±0.11%, phosphorus (P) of 0.11±0.02% and calcium (Ca) of 0.05±0.01%. In the feeding trial, diets with BJPBM significantly (P < 0.05) depressed chick growth. Feed intake was significantly (P < 0.05) reduced above 25% replacement rate whereas feed efficiency did not change much. There was no mortality in the control treatment and at 25% boiled Java plum bean-maize replacement rate. The study showed that BJPBM cannot replace MM in broiler starter diets without deleterious effects on the birds. The boiling treatment did not improve the nutritional value of JPB.
