Sentul chicken is a specific local chicken from Ciamis region in West Java and a dual- purpose type that can utilized for eggs and meat production. In other way, these birds are very good for chicken meat species, because they have a compact body and white skin colour. One of the alternatives to improve performance is by giving the ration added with a mangosteen peel meal (Garcinia mangostana). Mangosteen peel meal (MPM) is one of the medicinal plants used as a herbal medicine containing xanthone compounds as antioxidants, and antimicrobials. The research aimed is to find out of protein efficiency ratio of Sentul chicken fed diets containing mangosteen peel meal (Garcinia mangostana). This experiment used 100 day old chicks of Sentul chicken that were raised in cages until 10 weeks old. It was used completely randomized design, with four level of mangosteen peel meal (ration without MPM (R0), and ration that added 2.5% (R1), 5% (R2), and 7.5% (R3), of MPM, and five replications, each replicated consisted of five Sentul chickens. Protein consumption, body weight gain and protein efficiency ratio were parameters observed. The results that using mangosteen peel meal until 7.5%, gave no significant effect on feed and protein consumption, but the use of ration with the addition of mangosteen peel meal at 5% and 7.5% gave a significant effect on body weight gain and protein efficiency ratio. This research indicated that the addition of mangosteen peel meal (MPM) in the ration until 7.5 % gave the best protein efficiency ratio of Sentul chicken.
