DairyTalk 320: Genomic Selection: DNA Testing Reduces Genetic Defects in Cattle Breeding - by Helmut Demmelhuber

This podcast episode is based on a professional article examining
how genomic technologies are transforming disease management in
cattle breeding. The analysis explains that the apparent rise in
genetic defects largely reflects improved detection of mutations
that previously remained hidden. Through DNA testing and
systematic recording, breeders can avoid high-risk matings and
gradually reduce the prevalence of harmful traits in the
population. This strategy has already contributed to lower
economic losses associated with stillbirths and congenital
abnormalities. Overall, the article highlights how genomic data
is becoming a central component of health-oriented and more
efficient breeding programs. With comments on a "Hoards´
Dairyman"-article (February 2026) by Chad Dechow:
