MeSH headings : Animals; Antibodies / blood; Antibody Formation; Cattle; Cattle Diseases / immunology; Cells, Cultured; Ceruloplasmin / metabolism; Copper / administration & dosage; Copper / deficiency; Copper / metabolism; Cytokines / biosynthesis; Diet; Erythrocytes / enzymology; Erythrocytes / immunology; Immunoglobulin M / blood; Interleukin-1 / biosynthesis; Liver / metabolism; Male; Molybdenum / administration & dosage; Superoxide Dismutase / blood; Swine; Tumor Necrosis Factor-alpha / biosynthesis

TL;DR: Calves fed the Cu and Mo diets gained weight more efficiently than those fed the control and Cu + Mo diets during the 112-d study and had a more severe Cu deficiency based on depressed humoral immune response and superoxide dismutase activity. (via Semantic Scholar)

TL;DR: The data indicate that dietary levels of Mo and Cu can affect body temperature and feed intake responses to disease by affecting TNF and perhaps other cytokines. (via Semantic Scholar)

MeSH headings : Analysis of Variance; Animals; Cattle / immunology; Cattle / physiology; Colostrum / chemistry; Copper / deficiency; Copper / pharmacology; Copper / physiology; Diet / veterinary; Dose-Response Relationship, Drug; Female; Immune System / drug effects; Immune System / physiology; Immunoglobulin G / analysis; Immunoglobulin G / blood; Iron, Dietary / pharmacology; Liver / chemistry; Liver / physiology; Lymphocyte Activation / physiology; Lymphocytes / drug effects; Lymphocytes / physiology; Male; Mitogens / pharmacology; Molybdenum / pharmacology; Phytohemagglutinins / pharmacology

TL;DR: Copper deficiency and Cu deficiency coupled with high dietary Mo or Fe produced inconsistent immune function responses, indicating that Cu deficiency may not affect specific immune function of calves. (via Semantic Scholar)

TL;DR: A study to determine the effects of copper (Cu) depletion by feeding diets high in either iron (Fe) or molybdenum (Mo) on performance and Cu status of beef cows and calves found heifers receiving supplemental Cu had higher plasma Cu levels and ceruloplasmin activities than heifer fed the other diets.
