For the billions of animals slaughtered for food each year, the quality of the slaughter process is a critical welfare moment. Evidence-based improvements can significantly reduce fear and pain.
The slaughter moment is where welfare improvements can have an outsized impact — even small improvements in process consistency affect billions of animals each year. Pre-slaughter welfare involves transport conditions, lairage time, mixing of unfamiliar animals, and the sensory environment of the abattoir. Cattle are particularly sensitive to novel sounds, smells, and visual distractions that cause fear responses in the raceway. Stunning quality — measured by the proportion of animals rendered unconscious at first attempt — varies widely between facilities and is one of the most important measurable welfare indicators. Effective oversight, trained operators, equipment maintenance, and feedback systems to correct failures in real time are all essential components of high-welfare slaughter systems.
