Lameness is one of the most significant welfare problems in cattle, and early detection through improved observation and technology can dramatically reduce suffering and economic losses.
Lameness welfare impact is immense and often underestimated: lame cows experience constant pain with every step, affecting feeding behavior, social interactions, and reproductive health. The chronic nature means suffering persists for weeks or months, not briefly. Detection failures are a major welfare bottleneck - stockpeople may observe a cow limping but not flag it for treatment, or subclinical lameness goes unnoticed entirely until the animal is severely affected. Attitude toward lame animals matters enormously: farms with strong lameness management culture achieve 5-15% lameness prevalence, while farms that normalize lameness have 30-50%. Technology offers promise but cannot replace stockperson engagement and empowerment to act when they observe problems. Economic pressures that delay treatment are a welfare concern embedded in farm business models.
