Sheep Copper Management and Toxicity

Copper is essential for sheep health but the range between deficiency and toxicity is narrow, with supplementation requiring careful management to prevent both conditions.

Key Facts

Sheep are particularly susceptible to copper toxicity compared to other ruminants
High copper pastures particularly in parts of the UK cause chronic accumulation
Toxicity causes haemolytic crisis with acute jaundice and death if untreated
Copper deficiency causes swayback in lambs with permanent neurological damage
Feed analysis and blood testing enable copper status to be managed accurately

Welfare Considerations

Both copper deficiency and toxicity cause serious welfare harm in sheep. The narrow margin between adequate and toxic copper levels requires knowledge of local conditions and careful supplementation management to prevent preventable suffering from this essential but dangerous mineral.

What You Can Do

Test your pasture and feed copper content before supplementing sheep
Monitor flock copper status through liver copper analysis in casualty and cull ewes
Avoid feeding cattle concentrates or minerals to sheep due to higher copper content
