Sheep Welfare in Extensive Systems: Managing Health and Behavior in Pastoral Flocks

Sheep in extensive pastoral systems face distinct welfare challenges from intensively farmed species, but significant welfare problems remain underaddressed.

Key Facts

Approximately 1 billion sheep are farmed globally, predominantly in extensive systems
Lameness is the most prevalent welfare problem in sheep, affecting 5-10% of animals in many flocks at any time
Footrot and foot scald are the leading causes of lameness and cause significant chronic pain if untreated
Condition scoring is a practical tool for detecting undernutrition, which affects significant numbers in harsh winters
Shearing is an annual welfare event — skilled shearers cause fewer injuries than unskilled ones on the same animal
Mulesing — removal of skin around the breech to prevent flystrike — is banned in many countries but still used in Australia
Internal parasites (worms) are a major cause of chronic ill health, weight loss, and death in sheep, especially lambs
Sheep are prey animals with strong flocking instincts — isolation from the flock causes acute stress

Welfare Considerations

Sheep welfare in extensive systems is often characterized by the perception that natural conditions are adequate. In reality, flocks of hundreds or thousands of animals on open range can have significant welfare problems that go undetected for weeks. Lame sheep unable to keep up with the flock, animals with severe body condition loss, or those suffering from parasitic disease may not receive timely veterinary attention in large extensive operations. The welfare baseline in extensive sheep farming varies enormously — highly skilled farmers with good observation, veterinary access, and proactive health management achieve good outcomes; overstretched operations with limited stockpeople per animal may have persistent unaddressed suffering. Welfare improvement requires investment in stockpeople time, veterinary resources, and farm monitoring systems.

What You Can Do

Support welfare certification schemes that include lameness monitoring and treatment protocols for sheep
Advocate for mandatory lameness scoring and treatment records as part of sheep flock health plans
Choose wool and lamb products from producers certified under higher welfare standards where available
Support investment in parasitic disease monitoring and control programs that are accessible to smaller farms
Advocate for alternatives to mulesing to be adopted globally and mulesing to be phased out in Australia
Engage with wool industry bodies about the welfare implications of rapid mass shearing schedules
Support research into precision monitoring tools that can detect individual welfare problems in large extensive flocks
