Effects of breed (Angus vs Simmental) and copper and zinc source on mineral status of steers fed high dietary iron

Journal of Animal Science, 81(1), 318–322.

By: L. Mullis n, J. Spears n & R. McCraw n

MeSH headings : Animals; Biological Availability; Breeding; Cattle / genetics; Cattle / metabolism; Ceruloplasmin / metabolism; Copper / administration & dosage; Copper / blood; Copper / pharmacokinetics; Copper Sulfate / administration & dosage; Iron, Dietary / administration & dosage; Iron, Dietary / metabolism; Liver / chemistry; Liver / enzymology; Male; Nutritional Requirements; Nutritional Status; Random Allocation; Zinc / administration & dosage; Zinc / blood; Zinc / pharmacokinetics; Zinc Sulfate / administration & dosage
TL;DR: Results indicate that neither CuSO4 nor CuProt were effective at the supplemental concentrations evaluated in alleviating the adverse effect of high Fe on Cu status. (via Semantic Scholar)

2003 journal article

Estimated copper requirements of Angus and Simmental heifers

Journal of Animal Science, 81(4), 865–873.

By: L. Mullis n, J. Spears n & R. McCraw n

MeSH headings : Animals; Breeding; Cattle / growth & development; Cattle / metabolism; Cattle / physiology; Copper / administration & dosage; Copper / blood; Copper / metabolism; Diet / veterinary; Dose-Response Relationship, Drug; Female; Lactation / metabolism; Lactation / physiology; Liver / chemistry; Nutritional Requirements; Pregnancy; Pregnancy, Animal / metabolism; Pregnancy, Animal / physiology; Random Allocation
TL;DR: Results suggest that Angus heifers have a lower minimal Cu requirement than Simmental, and Cu supplementation of the control diet increased plasma Cu during gestation and greatly increased liver Cu in both breeds. (via Semantic Scholar)
