“What caught our attention was her massive frame, wide chest, and high-quality udder. She was the kind of cow that could look after herself and never had a bad day. In addition to that, she milked like crazy.” - Pat Conroy“Cows that have some power and strength, yet are still dairy, will ultimately outlast and out milk the high style younger cows that seem to be one-hit wonders. I think that Iron O’Kalibra is one example that proves this fact to be true.” - Pat ConroyTakeaways for Breeders: • Importance of balanced breeding goals (conformation and production) • Value of strong cow families and consistent breeding philosophies • Potential for excellence to emerge from any geographical locationhttps://www.thebullvine.com/donor-profile/decrausaz-iron-okalibra-the-swiss-holstein-queen-who-conquered-the-world/
