Cattle Tail Docking Evidence and Welfare

Tail docking in cattle has been practised to reduce mastitis and improve milker safety but evidence for benefits is weak while welfare costs are clear. Bans are in place in many jurisdictions.

Key Facts

Tail docking removes most of the tail switch at or near the first coccygeal vertebra
UK, most EU countries, Australia, and New Zealand have banned cattle tail docking
Evidence that tail docking reduces mastitis is not supported by well-designed studies
Docked cows cannot use their tails to disperse flies, increasing irritation and stress
Docking causes acute pain and phantom limb pain has been documented in cattle

Welfare Considerations

Cattle tail docking causes acute pain during the procedure and chronic welfare costs through inability to disperse flies and potential phantom limb discomfort. The claimed welfare benefits to milkers from reduced tail-slapping do not justify these animal welfare costs, particularly given the absence of evidence for mastitis reduction. Bans in most progressive dairy jurisdictions reflect appropriate application of the evidence.

What You Can Do

Support dairy farms that do not practise tail docking
Advocate for tail docking bans in jurisdictions that still permit the practice
Choose dairy products from farms committed to no tail docking
