^an = 10 pigs per treatment
^bControl treatment (CON) = pigs fed basal diet (0.0% β-mannanase) with saline injection
^cEnzyme treatment (ENZ) = pigs fed enzyme diet (0.056% β-mannanase) with saline injection
^dImmune system stimulation treatment (ISS) = pigs fed enzyme diet (0.056% β-mannanase) with LPS (Escherichia coli serotype O55:B5) injection
^eATTD, % = [(nutrient intake (kg) – fecal nutrient output (kg)) / nutrient intake (kg)] × 100
