Abstract. Phytogenics have been widely used as alternative feed additives to replace antibiotics in animal production. The present study aims to evaluate inclusion of S. cumini extract as feed additives on performance and haematological parameters of commercial broiler chickens. A total of 100-day-old commercial chickens (mixed sex) were randomly allocated to four treatments with five replicates. Each treatment was administrated different level of S. cumini extract in the drinking water (P0=control, P1=0.25 g/l drinking water, P2=0.50 g/l drinking water and P3=1.0 g/l drinking water). Commercial diet was provided to feed broiler during experiment based on nutrition requirement for starter and grower. Water and feed were given ad libitum. Data were collected to measure broiler performances (BW, FI, FCE and WTC) and haematological parameters. One way ANOVA was applied in this study and significantly different among treatments were stated (P≥0.05). The results indicated that inclusion of S.cumini extract as feed additives in drinking water did not significantly affected (P>0.05) on animal performances and haematological parameters of commercial broiler chickens. Therefore, it concluded that S.cumini extract can be applied as alternative feed additive due to no harmful effects of the S.cumini iextract on performances and haematological parameters.
