DairyTalk 88: From Calf to Reference Cow - Carmen’s Journey in Modern Genetics - by Helmut Demmelhuber

Progress in breeding isn’t just numbers - sometimes it has a
name.
In this DairyTalk episode, Helmut Demmelhuber tells the story of
Carmen, a Holstein cow whose journey from calf to reference
animal illustrates the real power of modern genomics and patient
herd management.
With an RZG of 145, strong fertility, and consistent production,
Carmen embodies what true breeding means: reliability, balance,
and lasting genetic progress.
Her legacy lives on - not in records, but in generations of solid
cows that work.
