Comparison of productive parameters of two analyzed groups (the first generation of imported gilts and the gilts born on the domestic farm) was conducted on a nucleus farm that imported the gilt lines from the TOPIGS breeding program. For the purposes of the nucleus pig farm, TOPIGS gilts were imported from Netherlands. The nucleus farm where the analysis of the two groups’ productive parameters was conducted imported the ancestral and grandfather lines to produce the parenting generation TOPIGS 40 sows which are bred with a Pietrain line of boars. The TOPIGS 40 sow is an animal based on A-line and B-line characterized by high fertility rate, excellent maternal characteristics, good capacity for growth, and quality meaty body. The analysis of productive parameters of the two observed groups of gilts (the first generation of 105 imported gilts and 88 gilts born on the domestic farm) resulted in significantly higher number of total born, born alive and weaned piglets after the first farrowing (P<0.001) as well as significantly higher number of total born and born alive piglets at third farrowing (P<0.05). The results of the observed qualities confirm the fact that, apart from the unquestionable genetic potential, other factors such as adaptation, accommodation conditions, microclimate, nutrition, and management have a significant effect on the increase of production results.
