The aim of the study was to investigate the fattening and meat qualities of young pigs of the Large White breed, to determine the criteria for selecting sows and boars of the “improver” category based on the age of reaching a live weight of 100 kg, backfat thickness at the level of the 6th–7th thoracic vertebrae, chilled carcass length, and the Kh3 selection index, as well as to calculate the level of correlation between traits and the economic efficiency of the experimental results. It was established that the young pigs of the controlled population are characterized by sufficiently high fattening and meat qualities, and in terms of the age of reaching a live weight of 100 kg, backfat thickness at the level of the 6th–7th thoracic vertebrae, and chilled carcass length, they exceeded the minimum requirements of the elite class by 6.57%, 31.0%, and 3.82%, respectively. A significant difference between animals of group II (Kh3 = –2.542 to –0.017 points) and group I (Kh3 = +0.027 to +2.781 points) was found for average daily live weight gain (by 24.0 g or 3.06%; td = 2.10), age of reaching 100 kg live weight (by 5.1 days or 2.82%; td = 3.51), backfat thickness at the level of the 6th–7th thoracic vertebrae (by 1.60 mm or 7.47%; td = 2.35), chilled carcass length (by 0.8 cm or 0.82%; td = 2.16), length of the bacon half of the chilled carcass (by 1.7 cm or 1.97%; td = 2.17), maximum (anterior) carcass width (by 1.7 cm or 4.89%; td = 2.53), and minimum (posterior) carcass width (by 1.6 cm or 6.42%; td = 2.35). The number of significant pairwise correlation coefficients between V. I. Khalak’s index (Kh3), fattening, and meat qualities of young Large White pigs reached 100%, which confirms the efficiency of its use in breeding and selection work with animals of the controlled population. The highest increase in additional production was obtained from young pigs of group II (+1.30%), in which V. I. Khalak’s index (Kh3) ranged from –2.542 to –0.017 points. The criterion for selecting sows and boars of the “improver” category is the compliance of the fattening and meat qualities of their offspring with the elite class according to the current Instruction on Pig Appraisal, as well as the value of V. I. Khalak’s index (Kh3) within the range of –2.542 to –0.017 points
