<![CDATA[This study was conducted to evaluate the effect of different levels of mangosteen peel meal (Garcinia mangostana Linn.) supplementation in commercial rations on feed consumption, body weight gain, and feed conversion ratio of broiler chickens. A total of 100 broiler chicks aged 8 days with uniform body weight were randomly assigned to four dietary treatments with five replications, each consisting of five birds. The treatments were: T1 (control, commercial ration without mangosteen peel meal), T2 (commercial ration + 2.50% mangosteen peel meal), T3 (commercial ration + 3% mangosteen peel meal), and T4 (commercial ration + 3.50% mangosteen peel meal). The experiment was conducted using a Completely Randomized Design (CRD). Data were analyzed using analysis of variance (ANOVA) and Duncan's multiple range test. The results showed that supplementation of mangosteen peel meal up to 3.50% did not significantly affect (P>0.05) feed consumption, body weight gain, and feed conversion ratio of broilers. The average feed consumption ranged from 603 to 640 g/bird, body weight gain ranged from 296 to 310 g/bird, and feed conversion ratio ranged from 1.99 to 2.17. It was concluded that mangosteen peel meal supplementation up to 3.50% in commercial rations did not improve the production performance of broilers.]]>
