This study was conducted to find the effect of inclusion of ginger (Zingnber officinale) and thyme (Thymus vulgaris) and their mixture on broiler performance, carcass characteristic and bacterial count. One hundred and sixty eight one day old broiler (Ross 308) chickens were allocated randomly to seven dietary treatments from 0–42 day of age with two replicates (12 birds/pen). The experimental diets were: control (T1), 0.25% ginger powder (T2), 0.5% ginger powder (T3), 0.25% thyme powder (T4), 0.5% thyme powder (T5), 0.25% ginger + 0.25% thyme (T6) and 0.5% ginger + 0.5% thyme powder (T7). Result showed that birds consuming 0.25% ginger and 0.25% thyme had significantly higher body weight and average weight gain at day 14 of the experiment compared to the control. Similarly, body weight measured at 42 day of the experiment was significantly higher in group fed 0.25 and 0.5% thyme powder. Birds consumed 0.5% thyme powder had significantly higher feed intake during 0-14 days, however, during the whole experiment (0-42 days), the mixture of 0.25% ginger + 0.25% thyme and 0.5% ginger + 0.5% thyme powder caused significantly higher feed intake. Overall 0.25% ginger + 0.25% thyme fed birds expressed the best FCR at the end of the experimental period of 42 days. Dietary supplementation of ginger, thyme and their mixture have a significant (P>0.05) increase in Lactobacillus count compared with the control group. The results indicated that the use of thyme and ginger improved the performance and beneficial bacteria of the gut.
