The aim of this study was to predict carcass quality clusters from the relative abundance of 20 biomarkers of meat tenderness and adiposity measured from rectus abdominis muscle samples. The carcass quality clusters were determined from 3 carcass traits: cold carcass weight, dressing percentage and conformation score, measured on 75 heifer carcasses. The prediction model established, using the ordered multinomial logistic regression, displayed that an increase in the abundance of Heat Shock Protein 27 and Enolase 3 could allow to improve carcass quality. This model with a success of 57.3%, allowed to discriminate with an accuracy of 72.2%, carcasses with the lowest quality. New data will be required to confirm our results.
