Research was performed on 1567 females Landrace and Yorkshire, and 24 boars of Danish origin, or 5294 consecutive farrowing, and period of 2009 end of 2011 year. Estimated genetic parameters for litter traits size show the same tendency, and the legality and females pure breeds that produce 11-14 piglets weaned per sow per year or less. The influence of environmental factors, YS, and food technology and management showed no significant effect on the traits. Heritability and repeatability of live and dead piglets born, litter size and the fifth days after birth and the number of piglets weaned in the low category of hereditary whose values vary within the limits of 0.08 to 0.11 for the heritability of 0.14 to 0.17 for the repeatability of the analyzed traits.
