How shearing affects sheep welfare, the importance of timing and technique, and the welfare implications of wool abandonment.
Shearing is a genuine welfare necessity for modern wool breeds - unshorn sheep develop fleeces that cause overheating, mobility problems, and flystrike vulnerability. But shearing is also a significant welfare event in itself. Rough handling and poor technique cause injuries and intense fear responses in sheep. Restraint during shearing is inherently stressful. The welfare ideal is skilled, rapid shearing with minimum handling and stress, timed appropriately to avoid wool sheep being unshorn through hot summer periods. The declining economics of wool has created incentives that can compromise shearing quality and frequency.
