The aim of this study was to evaluate meat quality from animal with different Expected progeny difference for growth (EPDg) and the prediction power of cooking loss (CL) and Warner-Bratzler shear force (WBSF) using time- domain nuclear magnetic resonance (TD-NMR) relaxometry data and multivariate models. Samples from 74 Nellore bulls were separated into two groups according the EPDg. Longissimus samples were analyzed by reference methods such as CL and WBSF. The raw beef samples of the same animals were analyzed by TD-NMR relaxometry using Carr-Purcell-Meiboom- Gill (CPMG) and Continuous Wave-Free Precession (CWFP) pulse sequences. The CL and WBSF, measured in aged beef samples, by reference methods and NMR relaxometry and analyzed by principal component analysis (PCA) did not show any difference between the two EPDg groups. The multivariate regression PLS model results did not show any correlation between the CL and WBSF measured by traditional methods and the TD-NMR data acquired with CPMG and CWFP pulse sequences.
