E495 The Invisible Architects: How George Wiggans and Paul VanRaden Helped Double Your Herds’ Genetic Gain

You know Net Merit. You sort by it. You build your breeding program around it. But you've probably never heard the names of the two men who built the system that generates every number on every sire proof in North America.George Wiggans grew up milking cows on a dairy farm in Aurora, New York. Paul VanRaden was a 16-year-old DHI supervisor earning $2.20 an hour weighing milk for neighbors in Iowa. Neither planned to spend 38 years in the same government lab. Neither expected their math to reshape an entire industry. But from a quiet USDA facility in Beltsville, Maryland, they built the evaluation infrastructure that today drives billions of dollars in genetic decisions worldwide — and doubled the rate of genetic progress almost overnight. This is the story of how the most influential team in your barn never milked a single one of your cows.The Story You'll Hear:The calculus grade that sent a farm kid down a hallway to meet the professor who changed his lifeTwo years in Laos during the Vietnam War — and the unlikely path back to dairy geneticsWhy the "goat guy" at USDA ended up rebuilding the entire cattle evaluation systemThe moment a microscope slide with 50,000 markers made daughter proofs obsoleteThe calves that never arrived — how their math uncovered lethal genetic combinations hiding in plain sight for decadesAn industry that swore by daughter inspections forced to accept that DNA was a better answerThe $135,000 question: what genomic selection is actually worth to a 300-cow herd every decadeA Pioneer Award in Madison — and the man who retired from USDA only to walk across the hall and keep workingDr. George Wiggans and Dr. Paul VanRaden are not salesmen, AI marketers, or celebrity geneticists. They are career scientists who spent nearly four decades building the system you use every single day — the Net Merit formula, the genomic prediction model launched in January 2009, and the haplotype research that found lethal recessives your mating software now flags before you make the cross. Before their genomic evaluations went live, genetic progress was roughly $40 per cow per year. Since 2010, it has been $85. That delta is real money in real bulk tanks on real farms. Their story is a reminder that the most transformative forces in this industry don't always stand at a podium or appear in a catalog. Sometimes they sit behind a computer screen for 38 years, quietly rewriting the math underneath everything.Read the full article, "The Invisible Architects of Your Herd's Genetic Gain," at https://www.thebullvine.com/dairy-industry-professionals/the-invisible-architects-how-george-wiggans-and-paul-vanraden-helped-double-your-herds-genetic-gain/.
