The present study was carried out to clarify bioavailability of peptide zinc for weanling pigs.Twenty-five pigs (7kg initial weight) were allotted to five groups of each dietary treatment.
The experimental diets were basal, diets supplied Zn 25, 50, 100mg/kg of Zn as peptide zinc or 100mg/kg of Zn as zinc sulfate of diet.
Zinc concentrations in the liver, the femur and plasma were higher in pigs fed 100mg/kg of Zn as peptide zinc than in those fed the same amount of Zn as zinc sulfate. Pigs received 100mg/kg peptide Zn tended to have high solubility of zinc in the ileum than 100mg/kg zinc as sulfate.
It seems that the bioavailability of peptide zinc was approximately twice as much as that of zinc sulfate.
