DairyTalk 331: Genotype and Phenotype - aligning genetics with management for real progress - by Helmut Demmelhuber

This episode is based on a technical article examining the
fundamental distinction between genotype and phenotype in dairy
cattle breeding. It highlights how observable traits and
performance are heavily shaped by environmental conditions,
limiting their value as indicators of true genetic merit. The
discussion outlines how genomic tools enable a more accurate
assessment of hidden genetic potential and reduce the risk of
selection errors based on appearance alone. At the same time, it
underlines that superior genetics require appropriate management
conditions to be fully expressed. Sustainable breeding progress
therefore depends on combining precise genetic selection with
effective herd management.
