Pig transport density standards directly affect mortality rates, injury levels, and thermal stress during commercial transport, with welfare-positive standards achievable at modest cost.
Pig transport welfare is a point in the production chain where welfare improvements have dual benefits: reducing animal suffering and improving meat quality through reduced stress-related tissue damage. Appropriate stocking densities that allow pigs to lie down simultaneously, temperature management systems in transport vehicles, rest stop requirements for long journeys, and careful unloading protocols at slaughter plants all contribute to transport welfare. The commercial incentive of reduced carcass damage from transport stress provides economic support for welfare investment. Regulatory enforcement of existing transport standards is as important as the standards themselves given widespread non-compliance in some markets.
