Bioavailability of copper proteinate and copper carbonate relative to copper sulfate in cattle

JOURNAL OF DAIRY SCIENCE, 79(1), 127–132.

By: J. Ward n, J. Spears  n & E. Kegley  n

author keywords: bioavailability; copper; cattle
MeSH headings : Animals; Biological Availability; Carbonates / pharmacokinetics; Cattle / metabolism; Ceruloplasmin / metabolism; Copper / blood; Copper / pharmacokinetics; Copper Sulfate; Female; Liver / metabolism; Solubility
TL;DR: Two experiments were conducted to determine the relative bioavailabilities of Cu proteinate, CuCO3, and CuSO4 in heifers that had been depleted of Cu and in the absence of high Mo, Cu proteinates were similar in bioavailability toCuSO4 andCu proteinate A appeared to have a greater bioavailability than CuSO3.
