Abstract:
Experimental researches were intended to the study of biracial swine reproductive capacities Large White x Landrace and Yorkshire x Landrace combined with Pietrain paternal form and Landrace x Pietrain. A significant prolificacy was obtained by combining Yorkshire x Landrace and Landrace x Pietrain, which contributed to the growth of breastfeeding capacity and piglets weight in the period after foaling. As a result, the reproductive capacities of sows was improved due to the influence of animals genotype. This makes us recommend to production units the use of obtained results in the process of swine reproduction.
