One Herd, Five Years, No New Equipment: A Real Genetic Testing Case Study
Jorgensen Land & Cattle ·
Talk to Jamie Wolf about the impact of genetic testing on a commercial herd, and one example comes up quickly: a set of commercial females in the Nebraska Sandhills.
Back in 2019, the operation was dealing with real unevenness in their calf crop, cattle that just weren't coming out the way the family wanted. It's a familiar problem, and one that's easy to misdiagnose using only the traditional tools: an eye and a gate down an alley.
The operation didn't actually start DNA testing until a couple of years later. But once they did, the change was significant enough that Wolf describes going back years later and pulling DNA on the heifers — by which point sorting purely by eye would have meant guessing.
Here's the detail worth paying attention to: none of this required new facilities or new equipment. The only thing that changed was adding one process, pulling a DNA sample and reviewing the results before making selection decisions. That's it. No capital investment, no overhaul of the operation. Just a new decision point added to a process the ranch was already running.
Interestingly, when JLC originally studied how long this kind of transformation might take for a herd starting from scratch, their estimate landed close to what actually played out: roughly five years of consistent testing to move a herd meaningfully in the direction they wanted.
It's a useful reminder that genetic testing isn't a quick fix — it's closer to a discipline. The return is real, but it compounds over years of consistent decisions, not a single season of dramatic change.
