This study conducted to determine the effect of dietary Thyme vulgaris in broiler chicks on some productive&biochemical parameters.

Atotal of 60 Ross broiler chicks of one day old have been raised for 32 days under agood hygienic condition.The chicks were randomally divided into two groups:Treatment group(T) &Control group(C) each of one have 3o chicks.the Thyme Vulgaris powder added to ration of treatment group(0.5mg/kg food) along the time of experiment while the control group given the standard feed only.the results showed that the (T) group was significantly difference(p<0.05) better as acompared with (C) group in body weight gain at 32 day,but there are no significantly difference in feed conversion ratio between the two groups&also (T) group have reduce in mortility rate but insignificantly difference.also the (T) have reduced significantly difference in,cholesterol,glucose &increased significantly in total protein&globulin concentration in blood serum,.but there are no significant difference in albumin,calcium&phosphor concentration in blood serum between the two groups.

From this research we can say that the dietary Thyme vulgaris will improve the production&physiological body state in broiler chicks and there are no visual side effect.
