Adaptive responses of the bovine rumen epithelium and epithelial bacterial community in the rumen of Holstein cows recovering from a continous or transient long-term high grain feeding model

The feeding of high grain diets in cattle leads to microbial and host changes, and subsequently to health disorders. This study aimed to establish the effects of a continuous and a transient feeding model on the rumen epithelial bacteria, rumen absorption and host gene expression. This study showed that transient feeding of high grain disrupts the adaptation of the epithelial bacteria and the host gene expression in both the short and long term after forage feeding.
