Pre-slaughter handling and stunning quality determines the welfare of farm animals in their final moments, with evidence that high-quality stunning and reduced lairage stress are the most impactful end-of-life welfare variables.
Slaughter welfare is the final welfare variable in the production chain and one of the most impactful because it determines the quality of the animal last experience of life. Effective stunning that is reliably applied produces instantaneous loss of consciousness with no preceding distress. Poor stunning, rough handling, and stressed lairage conditions accumulate welfare costs in what should be the most controlled part of the production system. The technical and managerial tools to achieve consistent high-quality slaughter welfare are well-established and widely available.
