Attitudes of Swiss consumers towards meat from entire or immunocastrated boars: a representative survey.

Male piglets are castrated in order to prevent boar taint in pork. The surgical intervention is currently done without anaesthesia. Growing public concern about the welfare issue of this procedure forces the meat industry to evaluate alternative methods. The acceptance of such methods was studied in Switzerland within a large representative survey on the image of Swiss meat. Five questions were aimed at our subject. It was found that only a small part of the population has actually experienced boar taint. Nevertheless, the majority would not buy products made from tainted meat even if the absence of any perceivable boar taint and identical quality with current products could be guaranteed. The acceptance of meat from immunocastrated animals was low. Among the proposed four alternative methods, the production of entire males (with two options regarding processing of the tainted meat), immunocastration and castration with anaesthesia, only the last one seems to be acceptable to the interviewees.
