This study has been carried out to evaluate the use of drinking water-soluble probiotics as an alternative to Zinc bacitracin Antibiotic Growth Promoter (AGP) in an effort to reduce the concentration of ammonia excreta as a result of increased feed digestibility. The probiotic used contains 2.0 × 10 7 CFU mL −1 Lactobacillus sp, 1.6 × 10 7 CFU mL −1 Bacillus sp, and 7.4 × 10 9 CFU mL −1 Streptomyces sp. The excreta sample was obtained from 15 male Lohmann strain broiler chickens aged 35 days from a total population of 300 chickens that had previously been reared since Day Old Chick. The chickens were distributed into three treatments and five replications in a metabolic cage with a size of 50 cm × 30 cm × 56 cm for three days. This study used Completely Randomized Design (CRD) with Analysis of Variance (ANOVA). The addition of probiotic significantly reduced (P <0.01) water content and ammonia concentration of broiler chicken excreta. The addition of drinking water-soluble probiotics significantly increased (P <0.01) the feed intake and feed digestibility of broiler chicken. The use of probiotics was better than Zinc bacitracin in reducing excreta ammonia concentration and feed digestibility.
