Object of research are pigs of breed Dyurok, selection herds and their efficiency. The genealogic structure of new factory type is generated. For creation of new lines and related groups by a complex estimation and selection it is planned five appreciated ancestors. Number of animals of new factory type in selection herds is finished up to 40 boars (sires) and 316 sows. Work according to genetic potential of selection herds of planted pigs of breed Dyurok is lead. It is established, that parameters of polycarpic effect, milkability, quantities of pigs and weights of a jack at wean in 35 days at Dyurok sows have made 9,6 heads, 46,6 kg, 8,7 heads, 79,2 kg accordingly. It is revealed, that the most highly productive selection herds of pigs of breed Dyurok are concentrated in enterprise Zadneprovskij where parameters of similar attributes make 9,7 heads, 46,1 kg, 8,6 heads, 67,3 kg. All estimated and selected for self-repair boars of breeds Dyurok (11,1%) will be partially used for creation of new lines, and also as continuers available
