Abstract: The aim of this study was to evaluate the effects of mixture multi-strain probiotics (MP) and katapang leaves extract (CE) on performance and digestive organ weight of broiler chickens during the finisher period. Two hundred 21- day old broiler chicken were randomly placed to the five treatments and four replicates, with ten 10 chicken each replicate. Experimental diets included a basal diet only (T1), a basal diet with 6 g/kg MP and 1 g/kg CE (T2), a basal diet with 6 g/kg MP and 1.5 g//kg CE (T3), a basal diet with 6 g/kg MP and 2 g/kg CE (T4), and a basal diet with 6 g/kg MP and 2.5 g/kg CE (T5). The variables were initial weight, live weight gain (LWG), feed intake, and feed conversion ratio (FCR) and digestive organ weight. The data were analysed using analysis of variance and the Duncan test. The results demonstrated that adding CE along with MP substantially increased LWG and improved FCR (p<0.05), others variables were not affected by CE supplementation (p>0.05). In conclusion, inclusion of 1.5 g/kg Terminalia catappa L. extract combined with 6 g/kg multi-strain probiotics significantly improved live weight gain and feed efficiency in finisher broilers, without affecting digestive organ weight. Therefore, the optimum dose rate is 1.5 g/kg Terminalia catappa L. extract with 6 g/kg multi-strain probiotics in the diet.
