Tserenyuk O. Theoretical ground and practical realization of methods of increase of genetic potential of the productivity of pigs on the poligen-conditioned traqits

The object of the study. selection processes in improving the pig breeds Landrace and Welsh reproductive qualities of sows, the laws of species during their breeding. Subject of the study: the existing and the new breeding unit, created in the structure of the gene pool of the domestic pig breeds Landrace and Welsh and the reproductive ability breeds Landrace sows, Welsh, Large White, and others., Stress, fattening and greasy meat quality, chemical composition, physical and technological characteristics of meat and fat, gene polymorphism major QTL animals of different genotypes, blood biochemical parameters of different age and gender groups. Methods of the study. Zootechnical, statistical. The scientific novelty of the results. Solved an important scientific problem in breeding pigs - a persistent increase in genetic potential for productivity-mediated polygenic characters. First developed scientific principles and developed new techniques - the components of the complex methodological management and conservation of the local pig population of Welsh breed of Ukrainian breeding and identify further areas for breeding herd and leading progeny farms. Developed and implemented a regional system of hybridization, based on the effective use of new factory units in Landrace and Welsh as parental forms.
