Abstract: | Growth performance, organ biometrics, bone characteristics, and intestinal morphometry were evaluated in broilers fed a diet containing orange (Citrus sinensis L.) essential oil. A completely randomized design was used, with five treatments with orange essential oil (0, 100, 200, 300, and 400 mg kg−1 diet) and six replications with 20 birds per experimental unit. In the pre-starter phase, feed intake and weight gain of all birds linearly increased, while feed conversion decreased with the addition of orange essential oil in the feed. At day 21, bone density (Seedor Index) and body weight were higher in the birds that received the maximum level of essential oil (400 mg kg−1) compared with those not treated with essential oil. The observed effects resulted from the better functioning of the physiological mechanisms of digestion and absorption of nutrients, characterized by the increase in villus height. Glycemia and weights of gastrointestinal tract organs of broilers at 21 days of age were not influenced by the evaluated essential oil. The results show that the addition of phytogenic additives to the diet does not cause any physiological impairment in birds |
