Antibiotic Growth Promoters and Anise Seeds in Broiler Diets

Nafez A. Al-Beitawi, Safa S. El-Ghousein, Abdullah H. Nofal


The effect of replacing antibiotic growth promoter (Bacitracin Methylene Disalicylate: BMD) by anise seeds as natural growth promoter on broilers performance was studied. One-day old chicks were fed experimental rations for 42 days. The replacement of BMD by anise seeds significantly (P<0.05) increased live body weight, body weight gain and the antibody titer against Newcastle, inficious Bursal and infectious bronchitis diseases. The replacement of BMD by anise seeds also significantly (P<0.05) decreased feed conversion ratio and serum cholesterol and triglyceride concentrations. These findings suggest that anise seeds can replace BMD as growth promoter in broiler rations.
