Studies have shown that between the groups of bulls daughters breed differences in indicators of reproductive ability. Found that all groups of heifers with the exception of daughters of a bull Dowry 311 were characterized by practically identical values of the duration of pregnancy (P < 0,95), which was the average for all groups of heifers 279 days. The daughters of a bull Dowry 311 this figure was the short and 277 days, on average 3 days shorter than the daughters of all other bulls.
