ADG, average daily gain; ADFI, average daily feed intake. 1 Treatments: (1) basal diet; (2) basal diet + ZnO (3100 mg/kg d 1–14, 1550 mg/kg d 15–35 and withdrawn entirely d 36–45); (3) basal diet + mushroom powder (2 g/kg feed) containing 200 mg/kg β-glucan; (4) basal diet + Vitamin D2-enriched mushroom powder (2 g/kg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–c 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 = pen). * A faecal score of greater than 3 was categorized as diarrhoea. 3 Faecal score range: 1 = hard, firm faeces; 2 = slightly soft faeces; 3 = soft, partially formed faeces; 4 = loose, semi-liquid faeces; and 5 = watery, mucous like faeces.
