Where Jorgensen Genetics Begin

The Motherlode®

For over 60 years, we have made the same selection decisions in the same pastures. The bulls we sell, the semen in our catalog, and the embryos we now offer all trace back to this one cow herd.

One Herd, One Standard

The foundation everything flows from

Continuous Selection

For over 60 years we have made the same selection decisions in the same pastures, breeding females that are more balanced, efficient, and productive than the generation before.

One Closed Herd

We don't chase fads or piece together fragmented genetics. The Motherlode is a single, closed herd. One source, one standard behind every bull, straw, and embryo we offer.

The Engine of Our Operation

Sixty years of single-herd selection

Built, Not Bought

For over 60 years, the Jorgensen family has meticulously developed a single, closed herd. We don't chase fads or piece together fragmented genetics. We rely on continuous selection, rigorous data, and a commitment to producing functional, efficient, and high-performing cattle.

One Herd, One Standard

Every bull we sell starts with the Motherlode. Every embryo. Every straw. It's the foundation of everything we do, and it's why ranchers trust Jorgensen genetics year after year.

Our Life's Work

"You can't buy our best cows. But you can breed them."

The Motherlode cow herd is never sold. It is our engine and our competitive advantage, but its genetics are within reach.
