established. It is planned in future to bring the cross-breeding volume of Holmogory
and Holstein breeds to 45-50 %. Among traditional Holmogory cattle lines the highest
ranks of productivity per 1 lactation are obtained by animals of genealogical lines:
Nailuchshy СХ-0856, Limon СХ-0721 and Khlopchatnic СХ-1097. In each line bulls-
producers giving the best effect are selected by posterity quality. The best milk-giving
stock of traditional numerous lines of Holmogory cattle should be used in pure-breeding,
applying defined successful variants of selection for improving the milk-yield.
