Abstract

In order to identify regions of the genome associated with some meat quality traits in the Avileña Negra-Ibérica (ANI) breed in two muscles, the genomic regions cointainig the 205 genes differentially expressed (DE) between Psoas major y Flexor digitorum in this breed were taken into account. Genotypes of 397 ANI calves with the Illumina Bovine 50K SNP platform were available. Markers with a call rate bellow 98% or fixed were excluded from the analysis. A total of 3110 markers were within the DE genes (104) or within the flanking regions of the same genes. The traits included in the analysis were two sensory traits (flavor and tenderness) and two laboratory measurements (intramuscular fat and instrumental tenderness). The software used for the analysis was QXPak 5.0. Twenty markers were found to be associated with intramuscular fat (12), tenderness (5) and instrumental texture (3). None of the markers were associated to more than one character and in both muscles to the same trait. Twenty two genes were flanked by this markers and one of the markers was contained in one of the DE gene
