^aBlood was collected on d 8 of the experiment 6 h post-feeding, prior to the immune challenge beginning on d 10
^bn = 10 pigs per treatment
^cControl diet was a corn, soybean mean, and soy hulls based diet containing 1.33% β-mannans, and did not contain β-mannanase enzyme. Pigs on the control (CON) treatment were fed the control diet and estimates are representative of the CON treatment only
^dEnzyme diet was the control diet supplemented with 0.056% β-mannanase (Hemicell™ HT-D, Elanco Animal Health, Guelph, ON, Canada; endo-1,4-β-mannanase (160 × 10⁶ units/kg) from Paenibacillus alvei). Pigs on the enzyme (ENZ) and immune system stimulation (ISS) treatments were fed the enzyme diet. Estimates are representative of the ENZ and ISS treatments prior to immune stimulation
^eBasophils (Baso); eosinophils (Eos); immature neutrophils (Bands); lymphocytes (Lymph); mature neutrophils (Neut); monocytes (Mono); white blood cells (WBC)
