The Cow Herd

Built On Forty Years Of Maternal Selection

Our sale bulls start here, in a cow herd built on proven Krebs foundation females. We breed them every year to elite AI sires and develop them slow and sound on irrigated pasture.

Foundation Females

A Strong Base, Bred Forward

We built this herd on purpose. We chose Krebs Ranch (KR) foundation females because they’re the kind of cattle we want to raise — beautiful, phenotypically correct cows that have held up year after year. That gave us a strong base to start from. From there we researched the cow families that fit our program, invested in our favorites, and have kept our best every year since.

Cow-Family Spotlight

The Heartland Val Line

One family shows what the program actually does. KR Heartland Val 0083 is a solid, honest Krebs-bred female. Decent, not a standout. The story isn’t her; it’s what we’ve built on her. Three generations of careful sire selection have molded her line forward, until her best daughters and granddaughters outrun her on the numbers that matter.

That’s the whole point. We didn’t start with a superstar. We started with a good base and kept molding it — breeding our best females to the right sires and keeping only the ones that move the program forward.

How We Manage

Disciplined, And Deliberate

The maternal base is the raw material. What we do with it every year is the program.

Great Basin raised

Rotational grazing on irrigated pasture with winter alfalfa. We develop cattle on the same green Fallon ground we run on, selected for fertility and structural soundness, not finished in a feedlot.

No shortcuts

We wean around a year, later than most operations, then develop bulls and females to 18–24 months with no push for early condition. Slow, sound development builds the durability and longevity a commercial cowman needs.

Forty years of Mark’s stockmanship

Udder quality, fertility, longevity, disposition, structure. Mark has selected on these for four decades. The numbers matter, but they never override a cow that can’t hold up.

We AI the whole herd, every year

Every spring the cow herd is synchronized and AI’d to reputable sires that cross well with our cows, then our own herd sire, R9R Home Town 406, cleans up. He’s a powerful, sound bull who never takes a bad step, and his calves are exactly what we’re after. We research every mating, pick what fits our program, and invest in it. That discipline is why the calf crop keeps getting better.
