چکیده
The prohibition uses of antibiotics and coccidiosis opens the door for research into natural alternatives to be used enhance animal performance. Origanum Majorana (OM) is a native plant in Middle East which have many secondary nutritional components that affect broiler Three hundred seventy-five, one-day-old (Ross 308) chickens were distributed five treatments with three replicates per treatment. Treatment T1 was positive control had fed coccidiostat. T2 negative control, feeding without T3, T4, T5 same feed as 0.5%, 1%, 1.5% added OM leaf powder. rearing period extended 35 days. Performance parameters measured weekly. Four birds from each pen slaughtered carcass cuts weighed. Breast thigh meat samples stored at 5Cο 7 days, color pH days 1, 3, 5, slaughtering. Feeding level 0.5% showed significant (P<0.05), increase total intake final body weight (3920 g, 2630.15g) compared other groups. lowest FCR obtained T4 on weeks 4, 5 (1.34, 1.33, 1.51, respectively). There no differences between breast L*, a*, b*, pH. L* value (59.19) tends improved (P=0.0873) due use In all means values increased significantly during storage while reduced. Using will performance may improve quality when it component substitute coccidiostat antibiotics.
