Carbon dioxide stunning is used only in large pig abattoirs. then fully hoisted to hang clear of the floor so that the viscera fall out under At this point, the pig can be lowered to a comfortable working height where we can begin the process of evisceration by cutting a wide swath of flesh just beneath the pigs tail and encircling the anus by a comfortable working margin.
