The study used 100 DOC Sentul chickens that were kept until 12 weeks old. The experimental design used was a completely randomized design (CRD) with 5 treatments and 4 replications, namely basal ration (PO), basal ration added with 50 mg/kg Bacitacin Zn (P1), Basal ration added with 125 mg/kg ENF (P2), Basal ration was added with 250 mg/kg ENF (P3), and Basal ration was added with 375 mg/kg ENF (P4). The parameters observed were protein consumption, body weight gain, carcass weight, protein conversion, and meat protein conversion. The results showed that the five treatments had a significant effect on all treatments in Sentul chickens. It can be said that providing a basal ration that was added up to a level of 375 mg/kg of noni fruit extract supplemented with Cu and Zn (P4) quantitatively had results that were close to the positive control results (P1) so that the noni fruit extract with Cu and Zn supplements was expected substitute for antibiotics that can improve livestock performance.enCC BY-NC-SA 4.0https://creativecommons.org/licenses/by-nc-sa/4.0/conversion meat proteincarcass weightfeed additivenoni fruit extractSentul chickenArticle
