Plain-English summary
Four young horses grazing near industrial areas showed signs of poor growth, limping, and bone deformities. These issues were linked to low copper levels caused by too much zinc in their diet, likely from the pasture they were eating. The high levels of iron in the grass may have made the situation worse. Treatment focused on correcting their mineral imbalances, which helped improve their health and mobility over time.

Abstract
Four young horses grazing pastures near industrial plants developed illthrift, lameness and skeletal abnormalities characterised by periarticular enlargement of the long bones. The clinical signs and lesions were attributed to hypocuprosis induced by an excessive intake of zinc from pasture. High pasture intakes of iron may have further compounded the problem.
