Pig transport causes significant stress and injury through loading, journey conditions, and mixing of unfamiliar animals, demanding improved standards throughout the transport chain.
Pigs enter transport already stressed from farm handling, then experience noise, vibration, crowding, unfamiliar animals, and extreme temperatures. Loading in particular involves intense fear responses - pigs are naturally cautious about novel environments and ramps. Trained loaders using non-aversive techniques significantly reduce stress indicators compared to those using electric prods. Minimizing mixing of unfamiliar pigs before transport eliminates a major aggression trigger.
