Sažetak
Očevi su uticali na variranje uzrasta pri prvoj oplodnji, veličinu legla pri rođenju i zalučenju i perioda zalučenje-oplodnja svojih kćeri (P<0.001 do P<0.05). Uzrast pri prvoj oplodnji, broj živorođene i ukupno rođene prasadi su statistički značajno varirali (P<0.001 do P<0.05) pod uticajem korigovanog prosečnog životnog dnevnog prirasta ali ne i korigovane debljine leđne slanine i mesnatosti.
