The aim of this study was to study the effects of microencapsulation of thyme and cinnamon essential oils on growth performance, intestinal microbial population and meat quality of broiler chickens. For this purpose, a total of 320 one-day-old male 308 strain chicks were randomly divided into 8 dietary treatment groups consisting of 4 replicates with 10 birds per replicate and fed until d 42. The birds fed diets supplemented with essential oils had significantly higher feed intake (FI) and weight gain (WG) and had improved feed conversion ratio (FCR) compared with the control group in total rearing period (P < 0.05). Dietary inclusion of encapsulated cinnamon resulted in a higher count of Lactobacillus sp. compared to the other groups on 42 days of age, while any treatments did not significantly affect Escherichia coli count (P < 0.05). The thiobarbituric acid values in thigh meat after 7 and 14 d of storage at 4 °C were linearly decreased in diets inclusion of essential oils (P < 0.05). In conclusion, the addition of thyme and cinnamon to the diet of broiler chickens especially as microencapsulated is recommended.
