Abstract

The relationships between reproduction parameters of dams and their daughters were analyzed in 303 406 Holstein cows.Parameters of reproduction (days open (SP), first service to conception interval (PSI), corrected milk (FPCM) at first lactation of cows)were collected from 1st to 3rd calving interval. A multi-factorial analysis of variance was used to evaluate the data using the CORR and GLM procedures of the statistical program SAS. Correlations between SP of dams in 1st calving interval and SP of daughters in 1st to 3rd calving interval were found r = 0.13 to r = 0.23. Differences of SP length between the groups of daughters assigned to groups according to SP of dams were 15.56 days in 1st, 13.93 days in 2nd and 11.91 days in 3rd calving interval.
