DairyTalk 486: Why Average-Ranked Cows May Be Critical for Future Breeding Success - by Helmut Demmelhuber

This podcast episode is based on an article by Helmut Demmelhuber
examining the breeding challenges created by the rapid expansion
of in vitro fertilization (IVF) in cattle genetics. The central
issue is how breeders should manage a growing surplus of embryos
without sacrificing long-term genetic diversity. The article
argues that selecting exclusively for top-ranked animals may
accelerate genetic gain in the short term while increasing
inbreeding risks and reducing the breed’s adaptive capacity over
time. A three-tier breeding model is presented as a framework for
balancing progress with the preservation of valuable cow
families. The analysis highlights why sustainable breeding
success depends not only on identifying elite genetics but also
on maintaining strategic genetic reserves for the future.
