Farm Pig: Piglet Iron Supplementation

Iron deficiency anaemia is universal in housed piglets without supplementation, causing significant welfare harm through anaemia and immune compromise.

Key Facts

Piglets are born with very limited iron reserves and sow milk contains insufficient iron
Outdoor piglets access soil iron naturally but housed piglets require supplementation
Clinical anaemia develops within 2-3 weeks of birth without iron treatment
Standard iron dextran injection at 3-5 days of age prevents anaemia effectively
Oral iron supplements are available as an alternative to injection for welfare-conscious producers

Welfare Considerations

Iron deficiency anaemia causes weakness, pallor, rapid breathing, and immune compromise in piglets. Untreated anaemia is a preventable welfare harm that occurs universally in housed systems without supplementation. The welfare case for routine iron supplementation in housed piglets is clear and uncontroversial - it prevents a specific, measurable welfare harm at minimal cost.

What You Can Do

Administer iron supplementation to all housed piglets at 3-5 days of age
Use appropriate iron dextran formulations at the correct dose for age and weight
Consider oral iron supplementation as an alternative to injection where preferred
Record any piglets showing anaemia signs to identify supplementation failures
Ensure outdoor piglets have access to rooting areas with soil for natural iron access
