摘要

A feeding trial was conducted to investigate the effects of dietary oregano (Origanum vulgare?L.) essential oil (OEO) on broiler performance, cecal microflora and serum antioxidant activity. One hundred?and?eighty?(180)?1-day old broiler chicks?were randomly divided into four groups. Group I was kept as normal control and received basal diet. Birds of groups II, III and IV were treated with basal diet supplemented with 300, 600 and 1200 mg/kg of OEO.?Inclusion of 600 mg/kg?ofOEO in grower diet significantly increased body weight gain when compared with the control group (P 0.05), populations of cecal?Escherichia?coliwere significantly lower in 300 and 600 mg/kg OEO supplemented groups in comparison with?the?control and 1200 mg/kg OEO supplemented groups (P 0.05), antioxidant activity of serum was higher in OEO supplemented groups. In conclusion, OEO exerted?growth promoting effects and also displayed?potent antibacterial effects against cecal?E.?coli.
