However, changes also are required of the rumen epithelium, that is, the layers of tissue that make up the rumen wall.

In the April 2012 Miner Institute Farm Report, Cotanch discusses the epithelium’s adaptive responses to dietary changes during the transition period, as well as epithelial health when cows go off feed in early lactation.
