The Best Linear Unbiased prediction (BLUP) procedure of animal evaluation using WOMBAT was done for estimation of breeding values of sires. Estimated overall mean breeding values for BWT, AWWT and PADG were 0.046 ± 0.23 kg, 0.26 ± 2.4 kg and 0.0002 ± 0.009kg, respectively. The trends of sire breeding values for all growth traits were negative. The hypothesis, selection based on phenotypic performance of animals can bring genetic progress in the herd was rejected and it is concluded that selection based on physical appraisal did not bring genetic progress. The selection method should be updated and must be based on genetic evaluation of individual animals. The coefficient of change in genetic trends for BWT, AWWT and PADG were -0.00134 ± 0.0012 kg, -0.05 ± 0.011 kg and -0.0001 ± 0.000045 kg respectively. The reduction of genetic potential of sires over years implies that the selection method based on the physical appraisal was not efficient.
