Porcine intramuscular fat content and composition are regulated by quantitative trait loci with muscle-specific effects

ABSTRACT: Intramuscular fat (IMF) storage is a biological process with strong impact on nutritional and technological properties of meat, and also with relevant consequences on human health. The genetic architecture of IMF content and composition phenotypes has been thoroughly studied in pigs through the identification of quantitative trait loci (QTL) and the estimation of genetic parameters. A question that has not been elucidated yet is if the genetic determinants of IMF-related phenotypes are muscle specific or, conversely, they have broad effects on the whole skeletal muscle compartment. We have addressed this question by generating lipid QTL maps for two muscles with a high commercial value, gluteus medius (GM) and longissimus thoracis et lumborum (LTL), in a Duroc commercial population (N=350)
