AbstractThis experiment was conducted to investigate the effect of adding different levels of dietary Marjoram (Origanum vulgarae) powder supplementation in some carcass measurement of broiler reared at 42 days. Four hundred and fifty one old day chicks of Ross 308 were randomly divided into five treatments (90 chicks per treatment) with three replicates (30 chicks per replicate). Chicks were fed on starter for periods from1-22 day and finisher rations for periods from22-42 day with 23 and 20 % crude protein and metabolic energy 3027 and 3195.3 Kcal kg-1 diet respectively, in addition to the five levels of Marjoram powder 0, 0.5, 1 and 1.5 and 2 kg ton-1 dietary treatments T1, T2, T3, T4 and T5 respectively. Results revealed that the supplementation groups T2, T3, T4 and T5 exhibited higher (P<0.05) in carcass measurement and body weight.The T5 showed was superior (P<0.05) circumference of breast and body filling degree as compared with other treatments. Moreover superior (P<0.05) due to dietary treatments were also showed in circumambient of breast and lengths of thigh and drumstick bones in comparison with T1 group. In conclusion, supplementation of Marjoram (Origanum vulgarae) powder to broiler diet led to improve some characteristics of carcasses and its measurements.
