Table 4 Apparent ileal, cecal, and total tract digestibility coefficients of dry matter (DM), nitrogen (N), organic matter (OM), and energy (GE) in non-infected pigs (NC), Lawsonia intracellularis inoculated pigs (PC), and vaccinated Lawsonia intracellularis inoculated pigs (VAC)

From: Lawsonia intracellularis infected enterocytes lack sucrase-isomaltase which contributes to reduced pig digestive capacity
