Sheep Welfare: Fly Control and Blowfly Strike Prevention

Overview of sheep fly strike prevention approaches and welfare implications of different methods.

Key Facts

Blowfly strike can kill sheep within 24-72 hours if undetected
Prevention through insecticide application remains most effective in high-risk periods
Jetting and dipping have welfare implications requiring appropriate handling
Breeding for resistance and dagging reduce blowfly strike vulnerability
Daily monitoring during peak risk periods is the critical welfare management practice

Welfare Considerations

Sheep blowfly strike welfare requires a prevention-first approach combining management, insecticide use, and rigorous monitoring. Prevention is more welfare-positive than treatment of established strike. Good stockmanship including daily monitoring during peak summer risk periods is the most critical welfare practice. Insecticide treatment decisions require balancing welfare benefits against environmental impact. Breeding for resistance offers a long-term welfare and environmental improvement.

What You Can Do

Implement rigorous daily monitoring during peak blowfly risk periods
Use preventive treatments appropriately based on veterinary guidance
Follow SCOPS guidelines for sustainable blowfly management integrated with welfare
