Abstract

The present study was carried out in Poultry Department, Faculty of Agriculture. Alexandria University to evaluate the effect of adding some dried medicinal plants (M.P) as Nigella seeds (N.S), Chamomile flowers (CH.F). Thyme flowers (TH.F) and Hannala seeds (HS) at levels of 0.25. 0.25. 0.50, 0.25%, respectively, individually or in combination versus using Inc.Bacitraction (Zn B) or virginimicyin (VIR) at levels (20 mg/kg of diet) to broiler chicks diet on growth performance,nutrient di‌gestibility values, blood serum constituents and economical efficiency. Two hundred and forty hubbard broiler chicks at three weeks of age were used in this study. Chicks were weighed and randomly distributed into sixteen treatments, with three replicates (5 chicks of each). The ex‌periment was terminated when birds were 7 weeks old. Weight gain, feed intake, feed conversion and some blood serum constituents were meas‌ured. At the end of the experiment, digestibility values and carcass char-acteristics were measured. Results showed that : The Using of N.S.. TH.F, HS and CH.F at 0.25. 0.5. 0.25, 0.25%. dietary levels. respectively, individually or in combination, improved the performance compared to control and antibiotics (Zn B or VIR) supple‌mented groups. The use of 0.25% CH.F plus 0.25% N.S. improved body weight, body weight gain, feed conversion, carcass traits and proved to be more economical than the other treatments or control.
