Sheep Transport Welfare: The Evidence on Long-Distance Journeys

Long-distance transport of live sheep is one of the most welfare-contentious practices in the livestock industry, with documented suffering during journeys that can last days or weeks.

Key Facts

Australia exports approximately 1 million live sheep annually by sea, primarily to the Middle East — journeys lasting 2-3 weeks across the Indian Ocean.
Mortality rates during live sheep export voyages have reached 2-3%, with individual shipments recording deaths of thousands of animals.
Heat stress is the primary cause of mass mortality events, as tropical sea routes expose sheep in mid-ship pens to temperatures and humidity they cannot thermoregulate against.
Sheep transported by road for over 8 hours show significantly elevated cortisol, reduced immune function, and weight loss that takes days to recover.
EU regulations mandate maximum journey times, rest periods, water and feed access, and space allowances for sheep — but enforcement across borders is inconsistent.
Australia announced a phase-out of live sheep export by sea in 2023, responding to documented mass mortality events and sustained welfare advocacy.

Welfare Considerations

The welfare case against long-distance live animal transport rests on a substantial body of evidence documenting physiological and behavioral stress responses that increase with journey duration. For sheep, the evidence is particularly strong: beyond approximately 8 hours, welfare indicators consistently worsen, and beyond 24 hours, most studies show levels of stress, exhaustion, and immune suppression that are incompatible with good welfare. The economic logic of live transport — that importing live animals allows slaughter according to local religious requirements, and preserves shelf life — is real but increasingly challenged by technological alternatives including chilled and frozen meat combined with religious pre-slaughter certification programs. The trajectory of the evidence and public concern suggests that long-distance live transport is an industry under terminal pressure.

What You Can Do

Reduce consumption of lamb and mutton, particularly products from countries with high live export volumes.
Support Animals Australia and World Animal Protection campaigns for live export reform and phase-out.
Advocate for EU enforcement of transport time limits and welfare standards at borders.
Support the development of chilled and frozen alternatives that replicate the market functions of live export without the welfare costs.
Engage with your elected representatives to support national legislation restricting live animal export for slaughter.
