PSIII-16 Evaluating the impact of group stunning on physiological parameters of pigs in a small abattoir

Small abattoirs commonly process pigs and sheep in a handling system designed for cattle. Smaller species are usually stunned in groups in the cattle shackling area in front of the stun box. The purpose of this study was to determine the effects of stun order on physiological parameters in pigs. A total of 148 barrows and gilts were stunned in 29 groups of four to five pigs with seven control pigs. All pigs were moved together into the stunning...
