Assessment of stun quality at commercial slaughter in cattle shot with captive bolt

Cattle may suffer pain and distress if incorrectly stunned. Regular monitoring of stun quality in abattoirs is now required by EU law. This study aimed to assess stun quality in cattle slaughtered under commercial conditions. A stun protocol was developed to evaluate when inadequate stunning occurred. This included rating of identified symptoms into three levels […]

Factors Affecting Penetrating Captive Bolt Gun Performance
