DairyTalk 357: TPI Revision Confirms Structural Shift in Holstein Breeding Strategy - by Helmut Demmelhuber

This podcast episode builds on an expert analysis of the 2026
revision of the TPI formula, where protein gains weight while fat
is reduced in importance. It examines how this shift reshapes the
ranking of proven Holstein sires and favors genetic profiles with
higher protein efficiency. The discussion reflects a broader
structural change driven by processor demand for casein and
longer-lasting cows. These adjustments send clear economic
signals for breeding decisions at farm level. The episode
contextualizes why existing mating strategies and semen
inventories may need reassessment under the updated index
framework. With comments on a "The Bullvine"-article (April 1st,
