The basal buffer capacity of different combination of alternative forage and concentrate will be tested. After the single buffer agent addition, the treatment effect will be measured through fermentation performance and products assay. The mixture type of buffer agent will be tested in the final step to select the better mixture agent with high palatability and buffer capacity. The fermentation liquid pH, VFA and microbial protein synthesis efficiency will be including in evaluation parameters. The result from buffer capacity index (BVI) and diet digestion ability will provide a reference data for buffer agent application on alternative forage diet for high milk production ruminants.替代性芻料緩衝劑體外發酵Alternative forageBuffer agentIn vitro
