    Area of Science:

    • Veterinary Medicine
    • Animal Nutrition
    • Biochemistry

    Background:

    • Copper (Cu) is an essential trace element vital for numerous physiological processes.
    • Understanding copper metabolism is crucial for animal health and preventing metabolic disorders.
    • Variations in copper metabolism exist across different animal species, necessitating species-specific considerations.

    Purpose of the Study:

    • To provide a comprehensive review of copper metabolism in animals.
    • To highlight the factors influencing copper absorption, transport, and storage.
    • To discuss the mechanisms underlying copper-related diseases.

    Main Methods:

    • Literature review of existing studies on copper metabolism.
    • Analysis of factors affecting copper bioavailability and utilization.
    • Synthesis of information on copper-induced pathologies.

    Main Results:

    • Copper absorption varies significantly between monogastric and ruminant animals.
    • Dietary components such as molybdenum, zinc, and specific binding compounds influence copper uptake.
    • The valence state of copper ions impacts intestinal absorption.
    • Metallothionein and lysosomes play key roles in hepatic copper accumulation.
    • Copper-induced liver damage and hemolysis may stem from lipid peroxidation.

    Conclusions:

    • Copper metabolism is a complex process influenced by multiple dietary and physiological factors.
    • Differences in copper metabolism contribute to varied disease mechanisms and manifestations.
    • Further research into copper-related diseases can elucidate specific pathogenic pathways.
