In vitro study that was conducted dilution methods using Ketapang extract at 5%, 10%, 15%, 20%, 25% and 30% concentrations.<em> In vivo</em> study was conducted by randomly dividing 20 layers into five treatment groups, four per group. The chickens (except in group P0−) were infected with APEC aged 24 weeks. Then, the treatment was conducted according to the divided groups in one week. The said treatments are P0− (uninfected APEC and unadministered with Ketapang extract), P0+ (infected with APEC and unadministered with Ketapang extract), and P1, P2, and P3 (infected with APEC and administered with Ketapang extract with 5%, 10%, and 20% concentrations, respectively). The data from layers’ performance were analyzed using ANOVA and Duncan’s test. The dilution method (MIC and MBC) exhibited the antibacterial ability of Ketapang extract against APEC at 5% dose. The Ketapang extract administration in layers exhibited improved performance of chickens infected with APEC, with the administration of 10% dose of Ketapang extract showing the best result. In summary, about 10% concentration Ketapang extract can serve as an antibacterial agent and showed the best results in layers infected with APEC.</p>
