This research was conducted to investigate the effect of the usage of silk worms (Bombyx mori) pupa in rations on male quail performance. It used 120 male quails of 7 days old which were divided in to 5 treatments. Each treatment consisted of 3 replicationa, and 8 quails for eac replication. The level of silk worms (Bombyx mori) pupa meal in rations were respectively 0; 2,5; 5; 7,5; and 10%. The performances were feed consumption, ADG, feed conversion, mortality and carcass weight. This research was designed One Way Completely Randomized Design, and the data were analyzed by variance analysis and the significant results were tested by Duncan’s New Multiple Range Tesr (DMRT). The results showed that the performance of male quail were not affected by the treatment. Feed consumtion were respectively 10,77; 10,74; 10,76; 10,78 and 10,76 g/quail/day. ADG were 2,27; 2,18; 2,10; 2,16 and 2,10 g/quail/day. FFed conversions were 4,73; 4,92; 5,12; 4,97 and 5,12. Carcass weight were 69,16; 68,67; 69,15; 67,40 and 68,19 %. It was concluded that silk worms (Bombyx mori) pupa a meal may be substituting fish meal up to 10 % level of the total rations. Key words : male quail (Coturnix-coturnix japonica), silk worms (Bombyx mori) pupa meal, performance.
