DairyTalk 482: When pedigree records are no longer enough: Rethinking inbreeding monitoring in modern cattle breeding - by Helmut Demmelhuber

This podcast episode draws on a scientific study examining the
gap between pedigree-based and genomic estimates of inbreeding in
the Simmental population. The findings suggest that traditional
pedigree measures often fail to capture the full extent of
genetic change in highly selected breeding populations. Genomic
approaches provide a more direct view of homozygosity and allele
frequency shifts, frequently revealing stronger inbreeding trends
than conventional methods. A key insight is that genomic measures
based on neutral SNPs align most closely with pedigree estimates,
highlighting the role of marker selection in genetic monitoring.
The study offers an important framework for improving how
breeding organizations track and manage genetic diversity in the
genomic era. With comments on a "Journal of Dairy
