Bedövningsmetoder vid slakt av svin : en jämförelse ur djurvälfärdsperspektiv

Abstract: Stunning of pigs at slaughter constitutes of primarily two methods; carbon dioxide and electricity. Both methods have advantages and disadvantages from an animal welfare point of view. The purpose of this study is to compare different methods of stunning pigs from a welfare point of view. Questions included in the study are 1) What differences are there, from an animal welfare point of view, between CO2 and electricity as methods for stunning pigs? 2) What alternatives are there to the methods currently in use? 3) Which method for stunning pigs is preferable from an animal welfare point of view? This report is a literature review. The results of the study are not conclusive; which method is preferred differs between situations. Argon seems better than CO2 from an animal welfare point of view, and for electricity there is a conflict of interest between slaughter efficiency and animal welfare.
