Effect of pectin oligosaccharides and zinc chelate on growth performance, zinc status, antioxidant ability, intestinal morphology and short‐chain fatty acids in broilers

A 42‐day trial was conducted to investigate the effect of pectin oligosaccharides (POS) and zinc chelate (Zn‐POS) on growth performance, antioxidant ability, zinc status, intestinal morphology and short‐chain fatty acids in broilers. A total of 324 1‐day‐old Arbor Acres broilers were randomly assigned to three treatments with six cages of 18 chicks. Treatments were: (a) Control, 80 mg/kg Zn from ZnSO 4 ; (b) POS, 80 mg/kg Zn from ZnSO 4 + 482...
