The conducted researches allow to determine the following theoretical basis for the creation of flexible breeding management systems and processes in pig farming working with FT «Black Sea» ULW-3: ? due to increased breeding value of each next generations compared with previous one there is a feasibility of faster replacement boars-sires after index ratings of their descendants, this can speed up the level and efficiency of the selection process and the stability of the gene pool; ? give preference in the selection of replacement youngsters class distribution for
live birth weight М + , which is the most highly productive in the future; ? there is a shift towards increasing the number of individuals with a high frequency of М + options (for live birth weight, average daily gain) and alternative shift towards increasing the number of individuals with high frequency variations М – (for age achieving live weight of 100 kg, thick bacon, feed consumption) under condition of maintenance pigs different age-sex groups with recommended level of crude protein in the diet; ? it was determined the optimal level of intensity growing replacement young pigs FT «Black Sea» ULW-3 during ontogeny.
