Shearing is a necessary welfare procedure for domesticated sheep whose fleece has been bred to grow continuously, but improper timing and technique cause significant preventable welfare impacts.
Shearing presents a welfare paradox: it is essential for domesticated sheep welfare yet the process itself causes stress and potential injury. The breeding of sheep to produce non-shedding fleece has created a dependency on human intervention that is unavoidable. Proper shearing requires skill, appropriate timing relative to weather conditions, and humane handling - conditions frequently compromised in commercial operations where speed is prioritized. Shearing is acutely stressful regardless of technique, triggering elevated cortisol responses. The mulesing debate represents a case where preventing one welfare harm (flystrike) may impose another (acute surgical pain without analgesia), and non-mulesing alternatives are not yet universally effective.
