The degree of resistance to stress pigs is of great importance for the prediction of their performance and the implementation of appropriate breeding. Therefore, the study of the productive qualities of manufacturers of modern genotypes according to their adaptive properties in the conditions of industrial technology of pork production is an important issue.
Scientific and economic experiments were carried out in a plant breeding Limited Liability Company “Agroprime Holding” Odessa region, where the pig industry is conducted on the basis of modern technology using the latest technology developments and feeding the animals. For all groups used full feed.
The article presents the meat quality of boars of Large White breed and Landrace French selection for different stress inclination (I – stress resistant, II – stress and questionable III – stress-prone).
It was found that the best meat quality among Landrace boar were characterized by stress resistance of animals (I group), and the worst – stress prone (III group). Analyzing the meat quality by class distribution note, in particular, pig breeds Landrace class М+ was significantly (P <0.001) were superior to their peers class М0 and М- on 12.04 and 14.91%, respectively. Large White breed pig class M+ was significantly (P <0.001) superior to their peers class М0 and М- on 11.95 and 14.4%, respectively. In the boar class M+ tends to increase in weight of the posterior third sides and weight reduction of body fat. Based on the studies found that regardless of genotype stress resistant pig compared to stress and stress-sensitive uncertain are the best indicators of meat productivity. The prospect of further research is to determine the quality of meat products and resistance boars modern genotypes according to their stress stability. Keywords: pig, meat quality, stress-prone, Large White breed, French Landrace breeding classes distribution.

Представлены результаты работы со свиньями породы дюрок и предпосылки создания внутрипородного типа «Степной». Проанализированы продуктивные качества внутрипородного типа свиней породы дюрок украинской селекции «Степной» (ДУСС) в условиях ЧАО «Племзавод «Степной» Запорожской области. Представлены результаты бонитировки свиней вышеупомянутого типа. По комплексу признаков стадо свиней распределяется следующим образом: к классу элита-рекорд относят хряков – 84%, маток – 32%, к классу элита – 16 и 68% соответственно. Это свидетельствует, что основное поголовье маток и хряков стада соответствует только классу элита-рекорд и элита. Отмечено, что свиньи нового внутрипородного типа украинской селекции проявляют высокую эффективность при скрещивании как при использовании в качестве отцовской, так и материнской формы. Установлено, что в условиях «Племзавод «Степной» созданы условия, которые способствуют проявлению генетического потенциала продуктивности свиней.

The results of the work with the Duroc pigs breed and conditions of creating of «Stepnoy» type intrabreed are given. The productivity of Duroc interbreed pigs type of Ukrainian selection «Stepnoy» (DUSS) in terms of PJSC «Pedigree farm «Stepnoy» Zaporozhye region is analyzed. The results of the appraisal pigs of aforementioned type, for complex traits are discussed; and the classifi cation of pigs had been done: class elite-record have 84% of boars, 32% sows, to the class of elite respectively 16% and 68%. This indicates that the main herd of females and boars herd corresponds only to the class of elite-record. It is noted that pigs of new interbreed type of Ukrainian selection show high effi ciency at the crossing, as if using it as paternal and maternal forms. It is established that the conditions of «Pedigree farm «Stepnoy» are contributed to the manifestation of the genetic potential of productivity of pigs.
