This research was conducted on Jl. Village Hall of Dusun II Sumberingin Gang Anggrek No. 40 Pancur Batu in December 2022 - March 2023. The design used was a completely randomized design (CRD) with 4 treatments 5 replicates so that 20 experimental units were obtained. The super free-range chicken used is 100 DOC weights. The treatments given were P0 (basal ration without synbiotic), P1 (basal ration + synbiotic 150 ml/kg ration), P2 (basal ration + sinbiotic 300 ml/kg ration), and P3 (basal ration + sinbiotic 450 ml/kg ration).
