The bidara plant is known as a plant that contains active ingredients and phytochemicals that have the benefit of stimulating physiological processes in the body to run well and have a healthy effect. This study aimed to determine the effect of giving bidara leaf extract on the production performance and mortality of broiler chickens. A total of 60 DOC broiler chickens were used in this study with an average body weight of 45 g which was divided into 4 treatments, including T0: control, T1: 10% bidara leaf extract, T2: 15% bidara leaf extract, T3: 20% bidara leaf extract. Each treatment was repeated 5 times with 3 research units per plot. The study was carried out experimentally in vivo using the Completely Randomized Design (CRD) research method. The data was processed by analysis of variance with the F test at the 5% level and continued with Duncan’s test. The results showed that the treatment had a significant effect (P<0.05) on production performance and mortality in broiler chickens at the 10% bidara leaf usage level. The use of bidara leaf extract can be used as a supplement in the maintenance of broiler chickens as a substitute for synthetic supplements.
