How transport stresses farm animals and what evidence-based management practices reduce welfare harm during long-distance movements.
Livestock transport involves a cumulative sequence of welfare stressors — separation from familiar environments, mixing with unfamiliar animals, loading via ramps under pressure, confinement in moving vehicles, thermal stress and dehydration — that individually would each cause measurable welfare harm. Combined across journeys of 8, 16 or 24 hours, the welfare costs are substantial. The most welfare-impactful improvements are: reducing journey length by moving carcasses rather than live animals where feasible; enforcing rest, water and feed requirements during long journeys; improving vehicle thermal management; and training transport operators in low-stress livestock handling. Slaughter at origin with cold chain transport is the single most welfare-effective structural alternative.
