Sir Inka May was the “Crown Prince” Minnesota breeders risked $25,000 on—a calf they could still pick up—and a century later his hidden red gene walked out of Madison as Supreme Champion of World Dairy Expo. From a 75‑cow show herd in Austin to the vast pastures of Carnation Milk Farms, this is the story of a bull who sired 33 All‑Americans and Reserves, built one of the most influential sire lines in Holstein history, and quietly carried a color factor the breed tried for decades to erase. By the time Golden‑Oaks Temptres‑Red‑ET stood Supreme in the Coliseum, the gene that once made breeders nervous had become the beating heart of Red & White Holstein pedigrees worldwide. This episode traces how that happened—and what was at stake each time someone chose to keep, cull, or double down on the blood of Sir Inka May.
