Here, we analysed quantitative trait loci (QTL) for fatty acid composition, one of the factors
\naffecting fat quality, in a Japanese wild boar \u00b7 Large White cross. We found 25 significant
\neffects for 17 traits at 13 positions at the 5% genome-wise level, of which 16 effects for 12
\ntraits at 10 positions were significant at the 1% level. QTL for saturated fatty acids (SFA) in
\nback fat were mapped to swine (Sus scrofa) chromosomes (SSC) 1p, 9 and 15. QTL for
\nunsaturated fatty acids in back fat were mapped to SSC1p, 1q, 4, 5, 9, 15 and 17. Using a
\nregression model that fits back fat thickness as a covariate, two of the QTL for linoleic acid
\ncontent on SSC4 and SSC17 were not significant, but one QTL for total SFA composition
\nwas detected on SSC5 with correction for back fat thickness. Wild boar alleles at six of seven
\nQTL tended to increase SFAs and to decrease unsaturated fatty acids. QTL for fatty acid
\ncomposition in perirenal fat were mapped on SSC2, 3, 4, 5, 6, 14, 16 and X. QTL for melting
\npoint (in back fat samples) were mapped on SSC1, 2 and 15. Wild boar alleles in QTL on
\nSSC1 and SSC15 were associated with elevated melting points whereas those on SSC2 were
\nassociated with lower melting point measurements.<\/p>\n","protected":false},"excerpt":{"rendered":"
