Prediction equations for Warner-Bratzler shear force using principal component regression analysis in Brahman-influenced Venezuelan cattle

► Multivariate analysis allows getting reliable predictors for beef tenderness. ► There is a high variation (88%) in WBSF due to its regression with carcass traits. ► Fat cover score and bone maturity contributed with the variation in WBSF. ► Prediction equations for WBSF would improve the current carcass grading system.
