  • Title: Intrinsic labeling of bovine milk with enriched stable isotopes of zinc.
    Author: Serfass RE, Lindberg GL, Olivares JA, Houk RS.
    Journal: Proc Soc Exp Biol Med; 1987 Oct; 186(1):113-7. PubMed ID: 3628249.
    Abstract:
    Bovine milk was labeled intrinsically with enriched stable isotopic zinc for human bioavailability studies. Intrajugular administration of zinc isotopes temporarily increased the plasma zinc concentration of Ayrshire cows by as much as 76%, but milk zinc concentration and the distribution of zinc between casein and whey did not change appreciably. Milk zinc isotopic enrichment reached 105 and 613 atom % excess for 67Zn and 70Zn, respectively within 4-12 hr of zinc administration and decreased gradually over several days. This degree of isotopic enrichment is sufficient for testing bioavailability to infants of intrinsic zinc from milk-based formulas.
