Sentul chicken is a specific local chicken from the Ciamis region in West Java and a dual-purpose type that can be utilized for eggs and meat production. The use of antibiotics continuously for maintenance to prevent and treat disease in Sentul chicken can lead residues in meat and eggs. To wean farmers for the antibiotic, it is necessary to find a natural antibiotic derived from herbal plants that Mangosteen Peel Extract (MPE). Mangosteen Peel Extract (MPE) is containing xanthone compounds like antioxidants and antimicrobials. This research was held to find out the effect of mangosteen peel extract on feed consumption, hen day production, feed conversion, and egg quality. This research used 40 female chickens aged seven months, which was kept in cages until three months, and each cage contains 2 chickens. The method used was a completely randomized design with four treatments namely P0 (ration without MPE), P1 (ration with 67 ml/kg MPE addition), P2 (addition of 100 ml/kg MPE) and P3 (addition of 133 ml/kg MPE) with five replications. Furthermore, treatment differences were tested using Duncan Multiple Range Test. The measured variables were feed consumption, egg weight, hen day production, feed conversion, thick of shell, egg yolk color, and egg cholesterol. The results showed the addition of MPE 133 ml/kg ration had a significant effect on egg production, egg weight, feed conversion, the thickness of eggshell, the color of egg yolk, and egg cholesterol but not significant to feed consumption, yolk index score and Haugh unit. It can be concluded that MPE can be used as a feed additive until 133 ml/kg ration to gave the best on production and egg quality of Sentul chicken.
