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.
