This study was conducted to evaluate the comparative effects of ginger, cinnamon and synbiotic on performance, carcass characteristics, blood biochemical and hematological parameters of broilers. A total of 224 male one-day-old broiler chicks were assigned at random to 7 treatments with 4 replicates (8 chicks per replicate) in a randomized complete block design. Dietary treatments consisted of basal diet with no additives (control) or the basal diet supplemented with synbiotic (Biomin IMBO), antibiotic (virginiamycin), 0.4% ginger, 0.8% ginger, 0.4% cinnamon or 0.8% cinnamon. The results showed that all supplemented with feed additives decreased (P 0.05) on the relative weights of spleen, bursa of Fabricius and thymus, and blood concentrations of glucose, total protein and low-density lipoprotein cholesterol level. In conclusion, this study showed that either 0.8 % ginger or 0.8% cinnamon could be suggested as effective alternative for virginiamycin with respect to the feed efficiency and health parameters
