An experiment using orange peel essential oil microcapsules (OPEOM) was added to the Sentul chicken feed to assess the effect of OPEOM on feed utilization, performance, and metabolite profiles in blood plasma. Two hundred two-month-old Sentul chickens were used, divided into five experimental groups, with the following treatments: MC0: Basal Ration, without OPEOM; MC1: Basal Ration + 100 mg OPEOM; MC2: Basal Ration + 150 mg OPEOM; MC3: Basal Ration + 200 mg OPEOM; MC4: Basal Ration + 250 mg OPEOM, respectively. All sample analyses were performed using standard procedures with the UV-VIS spectrophotometer and ELISA techniques based on reagent kit protocols were used in this research. The effects and differences in treatment responses were tested using analysis of variance based on a completely randomized design and Duncan’s test. The results showed that the chickens that received the MC2 treatment had the lowest malondialdehyde (P<0.05), at 0.04 mg/dL, compared to the other treatment groups (0.09 and 0.08 in MC0 and MC1). Similarly, this group showed the best results regarding feed utilization (73.68% DCP), performance (1473 g body weight), and blood biochemistry profile (8.27 mg/dL of total protein).
