What’s a fertility leader?

In April 2025, the US dairy genetic base was updated to reflect the amount of genetic progress made since the last base change five years ago.

Have you ever really thought about what’s involved to get highly fertile semen from the bull to your tank, and then into your cows or heifers? Fertility leadership is backed by the Alta people, processes and programs involved in every step.

PEOPLE

Fertility excellence is what drives our team! We hire and extensively train only those who share a commitment and passion to your herd’s reproductive success. From semen collection and evaluation to distribution and delivery, our barn and lab staff, veterinarians, distribution crew, technicians, and sales force are all committed to help you get cows pregnant.

PROCESSES

We deliver the highest quality semen through continual innovation. Our scientists on staff are always looking for the best ways to enhance semen quality through extender research, potency trials, and more. We implement the same, strict semen handling processes and quality control checks at each of our AI centers located in six different countries around the world.

PROGRAMS

We choose the industry’s leading sire fertility evaluation, CONCEPT PLUS, as the only way to measure Alta sire fertility. CONCEPT PLUS is based on pregnancy check results from DairyComp data in our large, progressive partner dairies. We update results every other month for the most reliable sire fertility information – and we’re transparent about which bulls offer superior or inferior fertility.

You can trust CONCEPT PLUS.

Twenty years ago, we challenged traditional fertility evaluations to align with the real needs of progressive herds: creating efficient pregnancies. CONCEPT PLUS goes above and beyond today’s industry evaluations to bring you the most trusted, accurate, and proven designation in sire fertility.

How does this genetic base change compare to previous base changes?

We’ve made more genetic progress in the past five years than during any other five-year span in recent history.

The charts below show the base change numbers for 2025, 2020, 2015, and 2010. As you can see from the charts, the base change in 2025 is significantly more for most traits than it was for previous base changes.

That means we’ve made more progress over the last five years than during any other five-year span in recent history.
