This experiment was conducted at Animal Resources Dept.

College of Agriculture, from 8-3-2014 to 19-4-2014 to study the effect of supplementing ginger (zingnber officinale ) and thyme (Thymus vulgaris ) powder and their mixture to broiler diet ( Ross 308) on performance , carcass quality and bacterial count( jejunum E.coli and Lactobacillus ) .

A total of 168 day old unsexed broiler chicks were randomly allocated to seven dietary treatments ( T1:control )(T2: 0.25% , T3: 0.50 %) ginger powder ( T4: 0.25% , T5: 0.50%) thyme powder and ( T6: 0.25% +0.25% mixture ( T7:0.50% + 0.50 %)mixture ( 2 replicate / treatment) each include( 12 birds / replicate pen ).

Feed was available ad libitum by using starter diet from 1- 28 daysWith crude protein level 21.94 % and 2921.9 Kcal ME/ Kg diet and finisher diet contain 20.07 % crude protein and 3038.2 Kcal.ME/ Kg diet was fed from 29 – 42 days of age .

Results reveled that final live weight was significantly ( p<0.05) highte in supplemented groups as compared to the control .

While feeding 0.25% level of both powder resulted in significantly ( p<0.05) better weight gain .birds fed diet T6 and T7 consumed significantly (p<0.05) less feed as compared with other groups .

Carcass quality , internal organ % and E.coli count were not affected by treatments .T2 ,T4 and T7 had significantly higher lactobacillus count compared to other treatments.

Bursa of fabricia relative weight was significantly (P<0.05) higher for the supplemented groups and for spleen in T2 and T4 .i t can be concluded from this study that supplemented broiler diet with ginger or thyme powder have a positive effect on broiler productive performance and microbial count .
