This study investigates the effects of the probiotic Saccharomyces cerevisiae on protein digestibility and gas emissions in pens of ducks. We conducted a series of experiments to evaluate the impact of dietary supplementation with Saccharomyces cerevisiae on the protein digestibility profiles and gas emissions on the ducks. A total of 24 grower ducks were randomly assigned to one of four treatments, which consisted of (T0) basal diet (without yeast); (T1) basal diet + Sc yeast 0.5 g/kg feed; (T2) basal diet + Sc Yeast 1.0 g/kg feed; and (T3) basal diet+ Sc Yeast 1.5 g/kg feed. The experiment was conducted with a completely randomised design, with five replications for each treatment. The ducks were reared for 35 d. On d 35-38 we observed nutrient digestibility and d 40 gas analysis using a chamber on 2, 4, 8 and 12 h after incubation. The results demonstrated that yeast supplementation did not have a significant effect on retention nitrogen. Yeast supplementation dose 0.5 g/kg can effectively reduce ammonia production after 2 hours after incubation. Our findings suggest that incorporating Saccharomyces cerevisiae into the diet of ducks is a promising mitigating environmental impacts associated with ducks waste.
