Particle associated rumen liquid microbiota in cows differing in SARA severity during 40%-grain and 65%-grain feeding
The aim of this study was to elucidate individual SARA severity of second lactation dairy cows. And to understand how SARA severity, classified in the first lactation, affected ruminal microbiome in the second lactation. It has not been addressed yet, if cows maintain their individual SARA severity throughout their lifetime.
