Resumo: | ABSTRACT Present study was conducted to investigate the effects of the dietary supplementation of coriander oil on broiler performance, blood characteristics, microbiota, and small intestine morphology measurements. A number of one-day-old broiler chickens (Ross 308) were allocated to five treatments, with four replicates according to a completely randomized design (CRD). Birds were offered either a corn-soybean meal basal diet (control), or the basal diet supplemented with 600 mg/kg of a flavophospholipol antibiotic, 100, 200, or 300 mg/kg coriander essential oil. At 42 days of age, two birds per replicate were selected for blood collection, slaughtered, and its intestinal microbiota and morphology were investigated. The results indicated that weight gain, feed intake, and feed conversion ratio significantly improved by the dietary inclusion of the coriander oil and antibiotic compared with the control treatment (p&lt;0.01). Blood biochemistry parameters were not affected by dietary treatments (p&gt;0.05). Birds fed the coriander oil and antibiotic diets had lower populations of Escherichia coli than control group in cecum (p&lt;0.05). The dietary treatments influenced the morphology of small intestinal villi. Birds fed antibiotic and coriander essential oil presented higher villus height and crypt depth compared with those in the control treatment (p&lt;0.01). Coriander essential oil supplementation significantly decreased epithelial thickness and the number of goblet cell of the small intestinal compared with the control treatment (p&lt;0.0001). In conclusion, coriander oil was shown to be an efficient growth promoter. The intestinal health improvement obtained with coriander oil was associated with improvements in broiler growth performance.
