Three breed groups were evaluated for slaughter weight (SW), average daily gain (DG), hot carcass weight (CW), eye-muscle area (MA) and dressing percentage (DP) of bulls resulting from crossing Karadi to Hereford and Charolais by least-squares procedure. Sire breed significantly affected SW and CW. Regression coefficients of performance measure traits (PMT) on feeding period and initial weight were significant. It was concluded that crossing Karadi cows to Hereford and Charolais sires improved SW by 22.97% and 14.01%, respectively, compared to straightbred Karadi.
