    “Clinical signs in dairy goats consisted of pale mucous
    membranes, anemia, emaciation, diarrhea, achromotrichia, brittle hair and alopecia.”

    Translated that means:

    • low FAMACHA
    • iron deficiency
    • poor body condition
    • diarrhea
    • pigment loss in hair
    • brittle hair
    • hair loss

    But these symptoms are very non-specific and it’s important to understand that there is no unique to copper physical symptom that definitively points to copper deficiency. When we treat based on these symptoms without actually knowing the goat’s copper status, we risk toxicity. Advanced toxicity is fatal.

    The clinical, pathological and reproductive aspects of an outbreak of copper deficiency
    in dairy goats and kids from the semiarid region of Pernambuco, Brazil are described. Ten
    adult dairy goats with clinical signs of deficiency and four kids presenting enzootic ataxia
    born from copper deficient does were separated from the herd, and examined. In the
    dairy goats, the average serum concentration of copper was 6.1±2.8mmol/L and iron was
    39.5±8.2mmol/L. In kids, the average serum concentration of copper was 3.8±0.9mmol/L
    and iron was 38.5±4.1mmol/L. Clinical signs in dairy goats consisted of pale mucous
    membranes, anemia, emaciation, diarrhea, achromotrichia, brittle hair and alopecia. The
    main reproductive alterations consisted of prolonged anestrus, embryonic resorption and
    high indices of retained placenta. The kids born from copper deficient dairy goats were weak,
    and presented neonatal or late ataxia until 70 days of life. Six dairy goats and four kids were
    necropsied. Most ovaries examined were small, firm and did not present viable follicles on their
    surface. Microscopically, there was reduction of viable follicles in addition to disorganization
    of follicular and stromal structures, with marked follicular atresia. Microscopically, changes
    in kids with enzootic ataxia consisted of neuronal chromatolysis and axonal degeneration,
    mainly in neurons of the spinal cord. In this study, the source of high iron was not identified,
    but it is known that outbreaks of copper deficiency can occur due to excess iron intake, mainly
    when adequate mineral supplementation is not provided for the goat herds.
