Currently, the commodity production seeks to obtain a final hybrid with higher meat quality through identify the most productive combinations breeds at crossing. In this regard, the study of the effectiveness of different options crossing of sows with boars of meat productivity is important. It is important to determine how the crossing (which breed of father) will have a greater effect on the reproductive performance of sows and will show above heterosis effect in the hybrid offspring. Finding the best combination of rocks at interbreeding and hybridization in order to obtain high performance of the reproductive ability at hybrid sows and determined the purpose of our research. The purpose of research: to evaluate the reproductive ability of sows by crossing them with terminal and purebred boars. The object of stud: the hybrid sows breed combinations of Large White × Landrace (LW × L), Landrace × Yorkshire (L × Y), York­shire × Landrace (Y × L). As a result of studies found that the most effective variations of crossing at hybridization are the combinations of hybrid sows (Large White × Landrace) with terminal boars 731 and 734.
