Investigations were carried out in single pig herd. It included 9 genotypes of sows (4 breeds and 5 groups of crosses of different crossing combinations) and 25.040 of their litters. Traits such as size of litter of Swedish Landrace sows (18.511 litters) and crosses of F1 generation (4651 litters) obtained by crossing of Swedish Landrace (SL) sows and boars of Large White breed (LW) were especially investigated. The second part of the investigation related to effect of sire (SL, LW and D) and dam breed (SL and SL x LW) on average demonstration and variability of number od live born piglets in first seven farrowings.
