Can Genetics Help Reduce Boar Taint in Pork? Canadian Researchers Are Finding Out

Boar taint — the unpleasant smell or taste that can occur in pork from intact (uncastrated) male pigs — is a real concern for producers and consumers alike. Castration has long been the go-to solution, but animal welfare concerns are pushing the industry to find alternatives. Researchers from Canadian Centre for Swine Improvement, the Centre de développement du porc du Québec, and the University of Guelph tested whether selecting boars with favourable genetic markers could reduce boar taint in their offspring. They ran three commercial trials across Québec and Manitoba, tracking over 1,600 pigs from weaning to slaughter. Offspring from low-taint boars showed slightly lower androstenone and skatole levels (the two compounds behind boar taint), but differences were small and rarely statistically significant. This research is a promising first step toward using genomic selection as part of a practical, on-farm boar taint reduction strategy — though genetics alone likely won't be the complete answer.
