¹ Treatments: (1) basal diet; (2) basal diet + ZnO (3100 mg/kg d 1–14, 1550 mg/kg d 15–35 and withdrawn entirely d 36–45); (3) basal diet + mushroom powder (2 g/kg feed) containing 200 mg/kg β-glucan; and (4) basal diet + Vitamin D₂-enriched mushroom powder (2 g/kg feed) containing 200 mg/kg β-glucan with 100 ug/kg additional vitamin D₂. ^a–b Mean values within a row with unlike superscript letters were significantly different (p < 0.05). ² A total of twelve replicates were used per treatment group (experimental unit = pig).
