The trial had included 8 generations of pigs and last 10 years of has been done at 4 different breeds: Landrace and Yorkshire as dam line and Duroc and Pietrain as a sire line. Trial included 62 sires, 1794 dams, 5694 progeny and slaughtered 838 heads in total. To examine fixed and random effects LS MME model has been used. Installed different selection criteria for L, Y and D, P showed positive and expected improvement. There are know significant differences at age of slaughter between L,Y and D, P showed significantly lower gain and logger age. Genetic trends for certain traits for all used traits showed a positive line. At the same time explain significance of optimal selection criteria during production.
