One of the efforts to improve feed quality is by using BLS (Bacillus licheniformis., Lactobacillus spp. andSaccharomyces cerevisiae) microbial services from the shrimp waste substrate, hereinafter referred to as PrebioticsBLS.BLS microbes are probiotic organisms that can improve the performance of livestock effectively (growth-promoter).PrebioticsBLS is expected to function as an emulsifier in increasing nutrient absorption and metabolism so that it iseffective in converting feed proteins into growth in Indonesia local chickens. The aim of the study was to determine theresponse of PrebioticsBLS in feed to the performance of Indonesia local chickens. The study used 120 local one-day oldchickens which were divided into 24 cage units, each cage unit consisted of 5 chickens, and kept for eight weeks. The experimental design used was a completely randomized design, consisting of 6 feed treatments (R0 = basal feed / CP15%; R1 = basal feed + 1.0% PrebioticsBLS; R2 = basal feed + 1.5% PrebioticsBLS; R3 = basal feed + 2.0%PrebioticsBLS; R4 = basal feed + 2.5% PrebioticsBLS; and RS = standard feed / CP 18%), each treatment was repeatedfour times. The variables observed were feed consumption, protein consumption, body weight gain, and proteine fficiency ratio. Data obtained from the results of the study were analyzed using analysis of variance, and differences between treatments were tested using Duncan's Multiple Distance Test. The experimental results showed that PrebioticsBLS (based on shrimp waste) can be used as a feed supplement in the local chicken feed formula, and the use of PrebioticsBLS at the level of 1.5-2.0% in feed (R4) is equivalent to the standard ration (RS / CP 18%).
