Loading and unloading pigs for transport is a high-injury-risk period where stockmanship quality directly determines welfare outcomes.
Loading is a welfare bottleneck because it compresses the interaction between animals and handlers into an intense short period under time pressure. Pigs experiencing loading stress show elevated cortisol and adrenaline, and physical injuries from falls on slippery surfaces or inappropriate handling cause lasting welfare harm. Low-stress stockmanship techniques — using animals' natural movement tendencies, minimizing noise, and avoiding electric goads — reduce both stress and injury rates. The investment in training and infrastructure pays back in reduced mortality and improved carcass quality.
