Abstrakt: Forty steers were utilized to evaluate the accuracy of predicting the weight of wholesale cuts from live beef steers by the use of electrogrammetry. Multiple correlations between the weights and the 14 line measurements obtained by electrogrammetry ranged from .60 for rib to .77 for chuck and flank weight. The flank and plate had the highest coefficient of variation, 12.4 and 15.6, respectively, while the chuck was the lowest with a value of 6.6. The combination of the four primal cuts to develop prediction equations gave greater accuracies than an individual wholesale cut alone. Sample size estimates were also calculated and results indicated that 10 runs per animal would be adequate for averaging dimension voltage.
