DairyTalk 367: Volatile genomic leaders, stable proven bulls: portfolio strategies gain relevance under new TPI - by Helmut Demmelhuber

This episode builds on an analysis of the April 2026 U.S.
Holstein TPI update, shaped by a major shift in economic
weighting toward protein yield. The so-called protein flip has
triggered notable ranking changes, elevating Aurora Gs
Woodford-ET to the top of the genomic list while reducing the
appeal of fat-dominant sires. The leading genomic group is
tightly clustered, increasing short-term volatility in the
highest ranks. In contrast, daughter-proven bulls such as
Sheepster provide comparatively stable reference points despite
modest adjustments. The discussion frames these changes within a
broader portfolio approach, emphasizing risk management and
profitability under the revised TPI structure. With comments on a
