Abstract Text: The objective of this study was to investigate the possibility of reducing the amount of androstenone and skatole in fat tissues of intact males using genetic markers. A total of 3,474 pigs were genotyped for 97 SNP markers from which 61, 80 and 83 of genotyped SNPs were polymorphic (MAF>0.05) in Duroc, Landrace and Yorkshire pigs, respectively. Approximately 51% and 5% of Duroc, 27% and 15% of Landrace, and 24% and 11% of Yorkshire pigs had androstenone and skatole levels that were above consumer acceptance thresholds, respectively. A two-step validation analysis was performed to examine the association of SNPs with androstenone and skatole levels. A number of SNPs had significant association with androstenone and skatole levels in each of the breeds. Using genetic markers for selection of breeding animals against high levels of boar taint is promising.
