The indicators of growth and development, fattening and meat qualities of pigs of the breeding center “Lozovoe” CJSC “Plemzavod-Yubileyny” of the Tyumen region were evaluated. The indicators that characterize the growth and development of young animals were taken into account: live weight, age, average daily growth. When the live weight of 100 kg was reached, an ultrasound device was used to evaluate the thickness of bacon, the depth of muscles and the yield of lean meat, which are in the database of breeding records for 2011-2020. To characterize the meat qualities, 1144 Landrace piglets were slaughtered, 275 - large white breed, 129 - Pietren breed, 339 hybrids (LxKB), 159 hybrids (LxD), 460 hybrids obtained from boars of foreign selection. A comparative analysis of commercial hybrids of various variants of crossing pigs of domestic and foreign selection is carried out. Processing of the research results was carried out in the laboratory of Molecular diagnostics and Biotechnology of the Don State Agrarian University. The influence of the breed is established.
