Abstract

This study aims to determine the effectiveness of using yeast named Saccharomyces cerevisiae as a probiotic in the maintenance of broiler chickens that are free from antibiotic administration and to obtain the most efficient dose of Saccharomyces cerevisiae as a feed additive. The success of this study supports the government's program for the future that will prohibit antibiotics usage in poultry feed, especially broiler chickens. This study consisted of 5 treatments and 5 replications for each treatment. Each replication consisted of 10 heads of broiler chicken aged 14 days. Treatment I = formulation feed (control) without yeast addition (P0), treatment II = control plus yeast 0.5 g/kg of feed (0.05%) (P1), treatment III = control plus 1 g/kg of feed (0.1%) (P2), treatment IV = control plus yeast 1.5 g/kg of feed (0.15%) (P3), and treatment V = BR1 commercial feed (K). Observations were carried out since the chickens aged 14 days to harvested on aged 35 days. Data were analysed using one way analysis of completely randomized design (CRD) by IBM SPSS Statistics 23. Significantly different results were followed by Duncan's new multiple range test (DMRT) to determine differences between treatments. The results of this study indicate that the addition of S. cerevisiae up to 1.5 g/kg of feed (0.15%) on dietary free-antibiotics did not affect production performance (P1, P2, P3) compared to control (P0), however still lower than broilers fed BR1 commercial feed (K). Addition of S. cerevisiae as probiotic on dietary free-antibiotic had a greater role for improving health status by 0% mortality and tends to increase lactic acid bacteria in the duodenum intestinal tract.
