Histology of colon tissue, comparing hay-fed and HG-fed goats.
Light microscopy cross-section of colon tissue from a representative hay-fed goat ((A) scale bar = 100 μm) or HG-fed goat ((B) scale bar = 100 μm). Comparison of colonic epithelial ultrastructure between hay-fed goat ((C) scale bar = 1 μm) and HG-fed goat ((D) scale bar = 1 μm). Colonic epithelial ultrastructure of junctional complexes in representative hay-fed goat ((E) scale bar = 200 nm) and HG-fed goat ((F) scale bar = 200 nm). M: mitochondria; TJ: tight junction.
