| Summary: | This study aims to evaluate the effect of the combined extraction of Andrographis paniculata and Moringa oleifera leaves as phytobiotics on the digestive microbiology of broiler chickens. The number of chickens used in this study was one hundred twenty-eight (128) chickens divided into 4 treatments, 4 replications where each replication consisted of 8 chickens. The treatments in this study were T0 (control), T1 (basal diet + 0.25% Andrographis paniculata and Moringa oleifera leaves), T2 (0.50% Andrographis paniculata and Moringa oleifera leaves), and T3 (0.75% Andrographis paniculata and Moringa oleifera leaves). The method used in this research is in vivo. Data analysis used a completely randomized design. If there is a significant difference, it is analysed using the Duncan Multiple Range Test (DMRT). The results of the study showed that the use of Andrographis paniculata and Moringa oleifera leaves had a significant effect on the number of lactic acid bacteria, Escherichia coli and Salmonella in the digestion of broiler chickens. T3 showed the highest number of lactic acid bacteria compared to other treatments, while T3 showed the lowest number of E. coli and Salmonella. The use of Andrographis paniculata 0.75% and Moringa oleifera leaves had a positive influence on the number of lactic acid bacteria in the digestion of broiler chickens.
