Four hundred and fifty-one old day chicks of Ros 308 were randomly divided into five treatments (90 chicks per treatment) with three replicates (30 chicks per replicate).

Chicks were fed on starter and finisher rations with 23 and 20 % crude protein and 3027 and 3195.3 Kcal / kg diet respectively, in addition to the five levels of Marjoram powder 0, 0.5, 1, 1.5 and 2 % in chick diets for T1, T2, T3, T4 and T5 respectively.

There is significant increase (P<0.05) and improved for sensory characteristics of breast and thigh meat for whole supplementation groups compared with T.
