Abstract

This experiment was conducted to determine the optimum level of green tea extract (GTE) in diets without antibiotics and to evaluate its effect on broiler performances. A total of 100 Cob broiler chicks were kept for a period of 5 weeks. Dietary treatments used in this experiment were antibiotic free group (basal diet as a control), GTE 0.5% (basal + GTE 0.5%), GTE 1% (basal + GTE 1%) and GTE 2% (basal + GTE 2%) and antibiotic added group (basal + 0.05% oxytetracycline). GTE supplemented group showed significantly higher body weight and better feed conversion ratio (FCR) than other treatments (P < 0.05) where highest live weight (2034 g/bird) was recorded in broilers group provided with 0.5% GTE. The best FCR (1.58) was observed in the group supplemented with 0.5% GTE. The obtained results also revealed significant (P < 0.05) difference among treatments in the lipid profile parameters (total cholesterol, HDL and triglyceride except LDL). Broilers treated with 0.5% GTE showed lowest total cholesterol (115.0 mg/dl), triglyceride (116.3 mg/dl) and highest HDL (30.75 mg/dl). In conclusion, GTE can be added in the diet @ 0.5% for better growth performances of broiler as an alternative to antibiotic without any negative effect on lipid profile.
