ABSTRACT: As a result of the worldwide ban on antibiotic growth promoters in food animals, essential oils have gained considerable importance. Animal meat and carcass quality traits have also been reported to be influenced by essential oils. This study investigated the effects of common nettle essential oil (Urtica dioica L.) in broiler chicken nutrition on performance and carcass quality characteristics. For this experiment which has lasted a 42-days, a total of 648 one-day-old broilers hybrid Cobb 500 were used. A total of 12 replicates were used per dietary treatment, leading to a total of 18 broilers per replicate, of an average initial body weight 34±0.58 g. The three dietary treatments com-prised a control diet (C), a control diet + 0.5% of nettle essential oil (EO1), and a control diet + 1.0% of nettle essential oil (EO2). Despite the carcass and breast yields being higher in the essential oil treatments (EO1 and EO2) compared to the control treatment (C), the thigh yields were unaffected by diet (P>0.05). Shank yield was higher in the EO1 and EO2 treatments as compared with the control (P<0.05) treatment. The weight of the viscera decreased (P<0.05) in the dietary treatments with the addition of essential oils. The EO2 treatment had a lower meat pH compared to the other two treatments. Based on the obtained results, it is concluded that the EO2 treatment was equally effective as the EO1, regarding the carcass traits, and therefore can serve as an alternative to the banned antibiotic growth promoters in broiler chickens.However further in vivo studies are required to assess the effect of the nettle essential oil on the gut health, immunity, and welfare of birds.
