DairyTalk 476: The Myth of the Perfect Calf: What Biological Randomness Really Means - by Helmut Demmelhuber

This podcast episode draws on a technical article examining
genomic breeding values and the gap between statistical
expectations and biological reality. The central issue is why
offspring from top-ranked genetic pairings can still perform well
below expectations. The analysis highlights that genomic
evaluations describe probabilities and averages rather than
precise predictions for individual animals. Sustainable genetic
progress therefore depends less on exceptional cases and more on
assessing breeding programs across larger populations and over
time. The discussion offers a practical perspective on managing
expectations and understanding the role of genetic variation in
cattle breeding.
