Sheep Copper Deficiency and Supplementation

Copper deficiency causes swayback in lambs and poor fleece quality in ewes, requiring careful diagnosis and supplementation management.

Key Facts

Swayback in lambs results from copper deficiency during gestation
High molybdenum in grass blocks copper absorption even with adequate dietary intake
Copper supplementation must be precise - toxicity occurs at relatively low excess
Individual boluses provide sustained release for at-risk ewes
Breed differences in copper metabolism affect supplementation requirements

Welfare Considerations

Copper deficiency causes serious neurological welfare harm in lambs and poor health in ewes. The precise balance between deficiency and toxicity requires veterinary guidance rather than routine blanket supplementation. Blood testing to confirm deficiency before supplementing is the welfare-sound approach.

What You Can Do

Test blood copper levels before starting supplementation programs
Consult your vet or nutritionist about breed-specific copper needs
Monitor supplemented animals for signs of toxicity
