Özet:

 

In this study, the genetic and phenotypic correlations between milk production traits (milk yield, lactation duration, dry period) and reproductive traits (the number of inseminations per conception, service period, calving interval and gestation period) in Holstein Cows were investigated. The data relating to milk and reproductive traits in the period of  1985-1992 of a Holstein herd at the Bala State Farm was used.  The genetic correlations were generally higher than phenotypic correlations between traits investigated in this study. In milk production traits, the phenotypic correlations between the milk yield and the lactation duration (0.41) and the dry period (-0.14) were statistically significant (P.
