The experiment animals were twenty chicken, divided into four treatments and five replications. Four different probiotic dosages, P0: controls, P1: drinking water supplemented by probiotic dosage 0.5 ml/liter, and P2: drinking water supplemented by probiotic dosage 1 ml/liter and P3: drinking water supplemented by probiotic dosage 1.5 ml/liter. The data were analyzed using the Analysis of Variance Statistic Method (ANOVA, α=5%) and if there were differences among the treatments, The Duncan’s Multiple Range 5% Test was used.
