DairyTalk 339: Few Lines, Global Impact: Genetic Convergence in Modern Holstein Breeding - by Helmut Demmelhuber

This podcast episode draws on an industry article examining the
growing genetic convergence within modern Holstein breeding. The
analysis explains how artificial insemination, global genetic
trade and genomic selection have created pedigrees that
increasingly trace back to a limited number of influential lines.
These developments allow elite sires to spread rapidly across
international populations and accelerate genetic progress. At the
same time, the resulting pedigree networks become more
interconnected, raising concerns about declining genetic
diversity. The article highlights the need to balance breeding
efficiency with the preservation of a broad and resilient genetic
base.
