Short summary
Estimated breeding values (EBVs), relative breeding values (RBVs), and daughter yield deviations of Holstein cows with exceptional longevity (more than nine lactations completed) and the RBVs of their sires were analyzed. Exceptional cows had on average significantly lower EBVs for yield traits but significantly higher RBVs for somatic cell score (RZS) and functional longevity (RZN). Correlations among the proportion of exceptional cows per sire and RZN, RZS as well as fitness were positive.
