Recognising Pain in Livestock: Science and Practice

Pain recognition in cattle, sheep, pigs and poultry has advanced significantly, with validated pain scales now available. Early identification enables timely treatment and improves welfare outcomes.

Key Facts

The Grimace Scale identifies pain through facial muscle changes in multiple species
Cattle show ear position changes, orbital tightening and altered posture when in pain
Lameness is one of the most common painful conditions in dairy cattle
Post-surgical analgesia remains under-used in many livestock settings
Pain negatively impacts growth, reproduction and immune function

Welfare Considerations

Animals cannot verbally report pain, making observer skill essential. Research shows farmers and vets who use validated pain assessment tools intervene earlier and more appropriately. Training in pain recognition is a high-impact welfare intervention with direct productivity benefits.

What You Can Do

Learn to use species-specific pain assessment tools like the Bovine Grimace Scale
Ensure pain relief protocols are standard for procedures like castration and dehorning
Work with your vet to develop farm pain management guidelines
Train staff in recognising subtle signs of pain in livestock
Advocate for mandatory pain relief requirements in livestock production standards
