Assessment of the influence of boars of different breeding on the indicators of sows and first generation mixeds

Relevance. Hybridization of pigs is one the main factors in production high-quality pork, since such animals combine genotype grandparent and parent breeds and, due to effect heterosis, have a high growth rate, improved meat qualities compared purebred ones. The paper presents an assessment reproductive large white sows productive young obtained as result industrial two-pedigree crossing. Methods. To implement scientific economic experience, 3 groups pairs-analogues Large White breed from Hypor company (KB Hypor) were formed. Sows 1st group crossed with Landrace boars PIC (Landrace Pic), 2nd – Genesus Genetics Genesus), 3rd Hypor). Results. According results research, it was found that multiple pregnancy higher by 7.7%, number stillborn piglets, on contrary, lower 0.6 heads than 3. weight nest piglets at birth experimental 9.9 6.1%, respectively, comparison analogues group. In hybrid during experiment, increase absolute, average daily relative gain live noted.
