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…
