DairyTalk 296: Polled Breeding at a Crossroads: A Dominant Gene Meets Genetic Diversity - by Helmut Demmelhuber

This episode draws on a technical article examining the genetic,
strategic, and economic implications of breeding for polled dairy
cattle. It explains the dominant inheritance of the hornless gene
and the importance of managing homozygous (PP) and heterozygous
(Pp) genotypes to achieve predictable outcomes. The analysis
cautions against an excessive focus on a single trait,
highlighting potential risks for genetic diversity, conformation,
and overall functional performance. It also questions whether the
premium prices often paid for polled genetics reflect true
biological value or are influenced by emotional market dynamics.
The podcast contextualizes these findings and underscores the
need for balanced breeding decisions grounded in comprehensive
health and performance data.
