In global pig production hybridization is one of the main methods of increasing the performance of commercial pigs. In Ukraine, for several decades, widespread industrial crossing of different breeds of pigs; only in recent years, when began an intensive importation of pigs foreign selection and use of foreign technologies proven to significantly improve slaughter and meat quality of commercial piglets can also through the use of a cross as parental forms of specialized meat breeds, lines and types of pigs that selected on combining ability. However, till remain problematic issues of effective use of new factory structures in various combinations to obtain the heterosis effect. The aim of our research is to determine the combining ability of pigs factory type when crossbreeding and hybridization, the study of meat quality and physico-chemical properties of muscle tissue of crossbred and hybrid pigs. Materials and methods research. Studies were conducted in an industrial complex PJSC “Bakhmut Agrarian Union” Artemovsky district, Donetsk region. The use of factory type in the schemes of crossbreeding and hybridization in industrial pig farming makes it possible to significantly increase the meatiness and to reduce the content of fat in carcasses. Proven efficiency in the use of maternal form LWxL when combined with boars of pietrain breed and DxP, which is confirmed by the calculation of specific combining ability. The study of physico-chemical parameters of meat of crossbred and hybrid pigs revealed the advantage of hybrid animals on individual quality indicators. In fact, despite the differences, meat and crossbred hybrid pigs characterized by good quality indicators.
