Molybdenum poisoning causes a secondary hypocuprosis, and clinical signs including chronic diarrhea, illthrift and depigmentation of hair. It occurs most commonly on pastures growing on soils naturally rich in the element, but can be caused by excessive pasture supplementation in an attempt to stimulate the growth of Rhizobium spp., the nitrogen-fixing bacteria of legume roots.
