DairyTalk 368: Index compression at the RZG-top: Managing RealSyn and Rome concentration in Holstein pedigrees - by Helmut Demmelhuber

This episode draws on a technical analysis of the April 2026
German RZG evaluations, highlighting the unusually tight
clustering among leading Holstein sires. While Connect retains
the top position, the underlying pedigrees show increasing
concentration around a limited number of bloodlines, particularly
RealSyn and Rome. The source examines how this development
elevates inbreeding risk and complicates long-term breeding
decisions. Daughter-proven sires such as Picard and Pattern are
positioned as stabilizing alternatives with greater reliability.
The discussion emphasizes that breeders may need to weigh genetic
diversity and functional traits more heavily alongside headline
index values. With comments on a "The Bullvine"-article (April
