Falkova, Lenka
Skatole and androstenone and their accumulation in fat are the main molecular compounds causing the unpleasant boar taint of porcine meat. This research focused on the variability of genotypes in two genetic markers associated with skatole (CYP2E1) and androstenone (TEAD3) levels in boars of five breeds in the Czech Republic. Four wide-spread commercial breeds and one autochthonous breed (genetic resource) - Large White, Landrace, Duroc, Pietrain and Prestice Black-Pied pig - were chosen for analysis. Fifty breeding boars from each were genotyped by PCR-RFLP method. Differences in genotypes and allele frequencies provide important information and the possibility of genomic selection of makers associated with boar taint compounds. The allele and genotype frequency results indicate a higher incidence of preferred alleles of both genes in Prestice Black-Pied pig and Pietrain compared with Large White, Landrace and Duroc.
