Effect of jamblang extract ( Syzygium cumini L ) on performance, carcass and giblet characteristics of broilers

The aim of this experiment was to determine the effect of using herbal feed ingredients jamblang leaves ( Syzygium cumini L ) as a feed additive on performance, carcass and giblet characteristics. A total of 100 DOC (CP 707) broilers were randomly assigned to 20 cage units with 4 treatments and 5 replications. Each treatment was given jamblang leaf extract in drinking water with different doses (P0 = control. P1 = 0.25 g/L, P2 = 0.50 g/L and P3 = 1 g/L). The feed used in this study was commercial feed for the DOC period up to the harvest period. Weight gain and feed consumption were calculated at the end of the study (4 weeks of rearing). All data were recorded to determine the performance, characteristics of the carcass and giblet. ANOVA was performed for data analysis. The difference between treatments was stated if P < 0.05. The results showed that the administration of jamblang leaf extract as a feed additive had no effect (P>0.05) on performance, carcass and giblet characteristics, but the wing carcass pieces showed a difference (P
