Effects of Diet Composition and Yeast Cell Wall Supplementation on Ruminal Fermentation, Gas Kinetics, Methane Production and Digestibility Assessed In Vitro Using Gas Production and DaisyII Incubator Systems.

BACKGROUND: Optimizing ruminant diets and mitigating methane emissions using feed additives like yeast cell wall is of growing significance in animal nutrition. OBJECTIVES: incubator. METHODS: diet. RESULTS: production, with greater effects observed in high roughage diets. CONCLUSIONS: volumes and influenced gas kinetics differently based on the R:C ratio. Further research is recommended to investigate the effects of YCW under different diet compositions, inclusion levels and shorter incubation periods.
