Abstract

The present study was carried out to investigate the effect of clove essential oil nanoemulsion (CEON) on performance of broiler chickens fed wheat-based diet. A total of 280 day-old broiler chicks (Ross 308, mix sex) were used in a completely randomized design with seven treatments and four replicats. The experimental treatments were; 1- control, 2- control supplemented with enzyme (En), 3- control supplemented with 200 mg/kg clove essential oil (CEO) and 4 to 7 were control supplemented with 200, 150, 100 and 50 mg/kg of CEON, respectively. The results of this experiment showed that in the whole rearing period, the feed intake and body weight gain of birds fed diets supplemented with 200 mg/kg CEON decreased significantly compared with control and En treatments (P≤0.05). In the whole period of experiment, chicks fed diets supplemented with CEO and 50 mg/kg CEON had better feed conversion ratio compared with control group (P≤0.05). Serum triglyceride concentration decreased significantly in chicks fed diets containing different levels of CEON compared to En treatment (P≤0.05). Relative weight of bursa increased in chicks fed diets containing CEO and 200 mg/kg CEON in comparison with control treatment. Supplementation broiler diets with CEO and 200, 150 and 100 mg/kg CEON decreased significantly Escherichia coli populations of cecal content (P≤0.05). According to the results of this experiment, supplementation broiler wheat-based diets with CEON may decrease Escherichia coli populations of cecal content.
