We’re excited to announce the launch of the GenoSource Future Breeder Program, an initiative to create meaningful, life-changing opportunities for participants in the World Dairy Expo Showmanship and Fitting Contests. We’re so appreciative of World Dairy Expo for allowing us to launch this embryo program, which allows us to invest in the next generation of dairy leaders!

Through the Future Breeder Program, participants gain hands-on experience in reproduction, genomics, and herd management, giving them practical tools and knowledge that support their growth as future leaders in the industry.

So how does it work?
🧬 GenoSource will have 5 embryo packages ready to be shipped, each package has 3 embryos
🧬 From each division’s Top 10 finalists, one recipient will be randomly selected to be awarded the embryo package
🧬 Showmanship: 3 packages awarded across Junior, Intermediate & Senior divisions
🧬 Fitting: 2 packages awarded across Intermediate & Senior divisions (combined top 5 of each gender contest)

A life well lived. 🕊️🤍 Miss OCD Robst Delicious-ET VG-87 moved on to greener pastures yesterday. As one of the Holstein breed’s defining genomic matriarchs, we are incredibly honored to have been part of her journey for more than 15 years.

Her impact on the breed is undeniable - over 350 direct descendants, more than 100,000 granddaughters in the United States alone, and at one point, nine sons ranked simultaneously among the Top 25 TPI proven sires. Delicious consistently delivered genetics that drove production, created lasting cows, and brought reliability to herds around the world.

She was the queen of her pasture, and her legacy will continue to shape the industry for generations to come.

Rest easy, Delicious, we will miss you.
