Key Discussion Points

  1. US Genetic Base Overhaul
    • Why the largest recalibration since 2020 impacts herd benchmarks (even for elite herds).
    • How to interpret relative rankings vs. absolute PTAs post-adjustment.
  2. Polled Genetics Breakthrough
    • Case studies: Cardiff P (Germany) and Triton-PP (Canada) redefine "elite" with welfare-friendly traits.
    • Why polled sires now compete on fat yield, fertility, and conformation.
  3. Germany’s Single-Step Revolution
    • How merging pedigree, genomic, and phenotype data boosts health trait reliability by 14%.
    • Practical impact: Fewer "genomic reruns" for functional traits.
  4. Swiss TPI Surprises
    • Sous-Moron BOSTON’s +80-point leap: What commercial herds gain from his fertility focus.
    • Sustainability meets protein: Why Swiss evaluations prioritize eco-efficiency.
  5. Global Takeaways for Breeders
    • Balancing act: Production vs. longevity in high-merit sires like DARTH VADR ($1,270 NM$).
    • Red flags: Managing inbreeding spikes amplified by genomic selection.
