alopecia copper deficiency iron zinc manganese copper absorption

TLDR High iron, zinc, and manganese levels in soil hinder copper absorption in cattle, causing deficiency.

In the Middle Paraíba region of Rio de Janeiro, Brazil, a study was conducted on 7 areas with bovines showing signs of poor health, including alopecia, depigmentation, and weight loss. Despite normal to high copper levels in soil and forage, the animals exhibited low serum copper levels, suggesting a deficiency. This discrepancy was attributed to high concentrations of iron, zinc, and manganese in the soil and pastures, which likely interfered with copper absorption, leading to a conditioned copper deficiency. The study highlighted the impact of mineral interactions on animal health.
