Trace Element Deficiency in Cattle: Welfare and Supplementation

How copper, selenium, zinc, and iodine deficiency affect cattle welfare and productivity.

Key Facts

Trace element deficiencies are common on certain soil types — particularly in western UK
Copper deficiency causes poor coat, anaemia, and neurological signs in calves
Selenium deficiency causes white muscle disease in young stock — potentially fatal
Supplementation through boluses, injection, or dietary addition corrects most deficiencies

Welfare Considerations

Trace element deficiencies cause chronic welfare compromise — poor growth, immune suppression, reproductive failure, and in severe cases death or neurological disease. Welfare-focused herd management identifies deficiency risk through soil and blood testing, and supplements appropriately before clinical signs develop. Over-supplementation is also a welfare risk — copper toxicity is a particular concern in sheep.

What You Can Do

Test blood trace element status in cattle on farms with suspected deficiency
Use species-appropriate supplements — never give cattle products to sheep
Work with your vet to design a trace element programme based on blood and soil analysis
