The aim of this study was to quantify the main effects influencing the tissue composition measured by computed tomography (CT) of pork cuts. A representative sample of the French pig slaughtering was selected in three abattoirs and stratified according to sex (50% castrated males and 50% females). An ear sample was analysed for Halothane gene (Hal). The left sides were cut according to the EU procedure and the four main cuts were CT scanned. Images were thresholded in order to determine muscle, fat and bone weight. Sex and Hal effects on tissues proportions were analysed by variance analysis. Interaction between sex and Hal was never significant. Sex was significant on all the tissues proportions in the cuts, except the bone % in ham and loin. Hal was significant on all the tissues proportions in the cuts, except the fat % in shoulder and the bone % in belly. Sex had a major effect (1 standard deviation) on the muscle% in the loin and the fat % in the shoulder. The important effects of sex and Hal on pork cuts composition should be taken into account by pork industry for sorting cuts and carcasses and for selecting suppliers.
