Table 3 Rumen papillae density, dimensions and surface area of hay-fed (CON) and high-grain-fed sheep (G7–28)

From: Morphological adaptation of sheep’s rumen epithelium to high-grain diet entails alteration in the expression of genes involved in cell cycle regulation, cell proliferation and apoptosis
