ResumenTenderness and marbling are polygenic traits used as indicators of good meat quality. Among different genes related to meat quality, mu-calpaine (CAPN1) and thyroglobulin (TG5) have been specifically linked to tenderness and marbling, respectively. Objectives: to estimate the allelic and genotypic frequencies of markers in CAPN1 and TG5 genes, and relate their presence to beef carcass quality. Methods: CAPN1 and TG5 polymorphisms were identified by PCR-ACRS and PCR-RFLP, respectively, validating their putative effects on beef carcass using real time ultrasound in Charolais candidate sires (n=80). Results: computed genotypic frequencies in CAP4751 and TG5 showed Hardy-Weinberg equilibrium, while CAP316 expressed deviation from equilibrium. Association analysis indicated a significant effect of CAP4751 on rib eye area (REA) (p<0.05) and intramuscular fat (IMF) (p<0.10), while TG5 showed a significant trend on yield grade (YG). Conclusions: these results support the use of these markers for assessing traits related to meat quality, and warrant further studies to validate their use in cattle herds for breeding purposes.es_ES
