^a,bMeans within rows with different letter superscripts differ significantly (P < 0.05).

Data are expressed as mean with pooled SEM for 6 replicates of 2 broilers each replicate.

¹Control = basal diet + 80 mg Zn from ZnSO₄/kg diet; Zn-POS-200 = basal diet + 200 mg/kg zinc pectin oligosaccharides (66 mg Zn from ZnSO₄ + 14 mg Zn from zinc pectin oligosaccharides/kg diet); Zn-POS-400 = control diet + 400 mg/kg zinc pectin oligosaccharides (52 mg Zn from ZnSO₄ + 28 mg Zn from zinc pectin oligosaccharides/kg diet); Zn-POS-600 = control diet + 600 mg/kg zinc pectin oligosaccharides (38 mg Zn from ZnSO₄ + 42 mg Zn from zinc pectin oligosaccharides/kg diet); Zn-POS-800 = control diet + 800 mg/kg zinc pectin oligosaccharides (24 mg Zn from ZnSO₄ + 56 mg Zn from zinc pectin oligosaccharides/kg diet).
