Heatmap of correlations between gene expression changes and phenotypic variations. Correlations were estimated for growth performances and carcass traits (A), liver weight, pH, and chemical composition (B), and liver fatty acid composition (groups of fatty acids) (C).

<p>The heatmap was generated using the CorrPlot package in R. The gene was included in the heatmap when a significant correlations for at least one phenotype was found (<i>P</i> < 0.05, Pearson product-moment correlations). Blue indicates negative correlations with values <i>r</i> < -0.51; grey indicates correlations values in the range -0.50 < <i>r</i> < 0.50; red color indicates positive correlations with <i>r</i> values > 0.51. BW: body weight; DG: daily gain; FS_IV: fat covering <i>in vivo</i>; MS_IV: body conformation; CW: carcass weight; MS_PM: carcass muscularity score; FS_PM: carcass fatness score; WT: liver weight. DM: dry matter; SFA: saturated fatty acids; MUFA: monounsaturated fatty acids; PUFA: polyunsaturated fatty acids; SCFA: fatty acids < C16; C16: fatty acids with 16 carbon chains; LCFA: fatty acids > C16; OCFA: odd-chain fatty acids; BCFA: branched-chain fatty acids; TFAC18_mono: Trans C18:1 fatty acids; CLAct_tc: conjugated linoleic acid <i>c</i>,<i>t/t</i>,<i>c</i> isomers; n_Ratio: ratio n-6/n-3.
