Casting and Handling Stress in Sheep

Casting sheep for foot care, shearing and veterinary procedures causes significant short-term stress and welfare impacts that can be mitigated through good technique and handling equipment.

Key Facts

Casting refers to turning sheep onto their back or side for handling procedures
Pressure on the rumen when cast restricts breathing and increases stress
Electronic handling equipment reduces the need for casting in many procedures
Calm, low-stress handling before casting reduces the fear response
Sheep can die from casting stress if left in a compromised position for too long

Welfare Considerations

Casting causes significant acute stress evidenced by struggling, vocalisation, elevated heart rate and cortisol. Respiratory restriction when cast elevates discomfort. The stress of repeated casting in the same session accumulates. Training stock to be handled calmly from birth dramatically reduces the welfare impact of necessary procedures. Mechanical handling aids allow procedures to be done with the animal standing where possible.

What You Can Do

Invest in sheep handling equipment to reduce need for casting
Train sheep from birth to accept handling calmly
Minimise casting duration and avoid leaving animals cast unattended
Use low-stress livestock handling techniques in all sheep management
Ensure all farm staff receive training in sheep welfare handling techniques
