The purpose of this study was to evaluate degree of taint compounds i.e., androstenone, skatole and indole of boars and their
relationship of traits so that to find possibility to breed low level taint compounds boars. Genetic parameters of Boar taint compounds
were estimated for 310 boars constitute of three breeds and one crossbred, include their genetic correlation with performance and
reproductive traits. The chemical analysis of three boar taint compounds were assessed by GC/MS/MS facilities using 3~5 g of fat
tissue collected by biopsies. The average of three compounds, androstenone (1.193±1.114 µg/g), skatole (0.092±0.096 µg/g) and
indole (0.062±0.082 µg/g) were obtained. Duroc showed the highest level of androstenone as 1.684±1.334 µg/g and those of native
breed was 1.287±0.673 µg/g, crossbred (Duroc X native bred) was 1.286±0.673 µg/g, Landrace was 0.086±1.077 µg/g and Yorkshire
was 0.823±0.763 µg/g. Native breed showed the highest level of skatole as 0.118±0.171 µg/g and Landrace showed the lowest level of
skatole 0.086±0.071 µg/g. Native breed also showed the highest level of indole of 0.237±0.023 µg/g and Yorkshire showed the lowest as
0.041±0.043 µg/g. The heritabilities of androstenone was 0.40, skatole was 0.17 and indole was 0.001. The genetic correlations of boar
taint compounds and performance traits were not significant (p>0.05). The genetic correlations of boar taint compounds and the dam
of boars reproductive traits were also not significant (p>0.05). It is concluded that it is possible to breed the low taint boars, since the
heritabilities of major taint compounds were moderate and their correlation with economic traits were not significant.
