DairyTalk 81: DNA Roadmaps - How Genetic Markers Guide Smarter Breeding - by Helmut Demmelhuber

Breeding begins in the genome.
In this DairyTalk episode, Helmut Demmelhuber explains how
genetic markers - from haplotypes and casein variants to polled
genetics - are transforming modern cattle breeding.
Haplotypes (HH1–HH6) prevent fertility losses, A2A2 and BB casein
improve milk and cheese yield, and polled genetics (pp/Pp)
promote welfare and safety.
Understanding these DNA markers means breeding with precision -
and turning science into sustainable success.
