Pig Sow Lameness Welfare Impacts

Sow lameness is a major welfare and production issue in intensive pig systems. Early detection and treatment are critical welfare priorities.

Key Facts

Lameness affects an estimated 10-30% of sows in intensive systems
Claw lesions are the most common cause of sow lameness
Lame sows have reduced reproductive performance and are culled earlier
Regular claw trimming reduces lameness prevalence significantly
Pain management is underused in lame pig treatment

Welfare Considerations

Sows with lameness suffer pain that affects their ability to move to food and water, compete socially, and nurse piglets effectively. Lame sows often show suppressed pain behavior, making detection difficult. Regular mobility scoring, proactive claw care, and prompt pain management protect sow welfare and extend productive life.

What You Can Do

Implement regular mobility scoring for sows in your herd
Provide regular access to claw trimming for all breeding sows
Ensure pain relief is provided for sows requiring claw treatment
Support farms with documented sow lameness management programs
