Interest in using herbal products as a source of antioxidants has increased in recent years, due to concerns about food safety and health. This study aims to determine the growth performance and intestinal histology of broilers given fermented aqueous extract of mangosteen peel (Garcinia mangostana L.) through drinking water. This research used a Completely Randomized Design (CRD) consisting of 4 treatments and 5 replications, each replication consisting of 8 broilers. The treatments given were: drinking water without fermented mangosteen peel aqueous extract (FMAE) as a control (P0), drinking water given 1.5% FMAE (P1); drinking water given 3% FMAE (P2), and drinking water containing 4.5% FMAE (P3). The results showed that broilers given aqueous extract of fermented mangosteen peel at levels of 1.5%, 3% and 4.5% (P1, P2 and P3) had no significant effect (P>0.05) on final weight, gain body weight, drinking water consumption, ration consumption, and Feed Conversion Ratio (FCR = feed consumption: body weight gain). Likewise, villi height, villi width and crypt depth showed no significant differences (P>0.05). Based on the research results, it can be concluded that the productivity of broilers given water extract of Garcinia mangostana peel fermented using Effective Microorganism-4 in drinking water has not been able to increase broiler productivity and improve intestinal histology. A more in-depth study is needed regarding the types of extracts and microorganisms used in fermentation.
