Assessing the impact of oscillating dietary crude protein on the stability of the rumen microbiome in dairy cattle

This study investigated the influence of dietary crude protein (CP) levels (13.8% or 15.5% CP of ration dry matter) and CP feeding patterns (constant over time (static) or oscillating by 1.8 percentage units above and below the mean every 48 hours) on the composition, diversity, and function of the rumen microbiome. Using a replicated Latin Square design with eight rumen-cannulated Holstein cows.
