In this STtalks we learn more about the genetics behind heat-tolerant cattle by diving into the slick gene. The group outlines how slick was introduced into the Holstein breed, and why heat tolerance matters for productivity in tropical and heat-stress regions. They also cover potential benefits for Beef on Dairy calves, recent progress in building higher-merit slick sire lines, and practical implementation using genomic testing, STrategy™, and Chromosomal Mating® to track and increase slick frequency over time.

After the April 2026 genetic evaluations, Canada experienced a rollback and changes to the LPI formula, we visit with Mike Barnum and Maxime Ten-Have to discuss how STgenetics® Canada is prepared to meet producer’s needs and handle industry change and market trends. Focusing on a few sires like BREEZER, RHETT, BECK, MYLO, BEATBOX and more, we dive into some unique offerings from the various portfolios like Eco$ and RCI sires. Additionally, we hear about the success of CAPTAIN daughters in Canada and what his release off the Legend™ program means to Canadian dairy producers.

To every farm mom wearing countless hats behind the scenes, this STtalks is for you. In this special Mother’s Day episode, we celebrate the moms who do it all long before the sun rises; feeding calves, packing lunches, balancing books, driving kids to school and supporting the farm team, while somehow still making home feel warm and cared for!

Let’s take a closer look at STgenetics®’ new laser-measured udder traits that are bringing even greater accuracy to the industry-leading Robotic Cow Index (RCI). Join Kevin Ziemba, Natalia Rodrigues, and Piush Khanal as they discuss these innovative new traits, their heritability, and how this selection can benefit not only robotic milking systems, but dairy operations as a whole. The conversation also dives into labor shortages, the growing need for more precise udder conformation data, and how technology is reshaping genetic selection on today’s dairy farms.

In this STtalks we discuss how the dairy industry defines and breeds for true efficiency beyond simply reducing cow size. Kevin Ziemba, Jocelyn Johnson and David Kendall join us to introduce two new STgenetics® traits; Mature Live Weight (MLW), built from over 1.8 million robot-recorded body weight records from more than 5,000 Holstein cows, and STurdy, an index combining linear type traits with MLW to identify cows that are wider and more robust relative to height and weight, designed to help producers moderate size while maintaining durability and functionality. This STtalks takes a deep dive into the concept of truly STurdy cows and how selection with these two new traits can achieve athletic, durable and profitable herds.

In the final episode of our Journey of Genetics Series, we are joined by Jack Hippen, STgenetics® North American and EU Sales Director, to break down what really happens when a producer buys that final straw and why it matters. From advancing gender-sorted semen performance to packing more female cells per straw, Jack shares how STgenetics® is pushing beyond sorting and driving true genetic progress. He dives into the power of Beef on Dairy as a third revenue stream and how genomics is reshaping herd decisions, boosting production, improving health and longevity and tightening efficiency from the ground up. It’s a fast-paced look at how smarter genetics translates to stronger profitability and a more sustainable future for dairy producers.

After a short break during April Genetic Evaluations, we’re back with our 6th episode of our Journey of Genetics Series! In this STtalks episode, we cover the logistics of distribution with Jim Chapman, STgenetics® Distribution Manager. He walks us through how semen moves from lab approval to your farm while maintaining temperature and quality, ensuring traceability as well. Jim goes over safeguards as well as improvements in tracking to ensure the product gets to where it needs to go when it needs to get there!

New release sire news is here! We have 33 New Sires, 10 of which are in the Legend™ program, the group averaged +3330 TPI with 15 bulls are over +1100 NM$, 23 bulls over +170 CFP, 23 bulls over +3.0 PL, three new Red sires and two new polled sires. The diversity and genetic impact this group of sires brings is exciting not only for the STgenetics® portfolio but also for our customers and the Holstein breed!

More proof news is here! David Kendall and Kevin Ziemba join us to review the results of STgenetics® Colored Breeds following the April 2026 Genetic Evaluations. They highlight strong Jersey momentum with bulls like GARLAND and GORMAN, additional high JPI young sires in the pipeline, and STyle™ standouts such as CANADIAN CLUB and LASPADA, plus new additions MR. BRIGHT and more. We learn more about the exciting Brown Swiss portfolio as well as how STgenetics®' STamina™ program has proven to be profitable and consistent for those who are breeding in that direction.

Proof news is here and this time we are joined by four members of STgenetics® Genetic Advancement team as we deep dive into the April 2026 genetic evaluations. Together they break down the impact of the latest TPI® updates, how the industry responded, and what these changes mean for the future direction of genetic progress. The team shares insights across key indexes, including TPI®, NM$, and STgenetics® Robotic Cow Index and Eco$ index, offering both a technical perspective and practical interpretation for breeders. From evolving emphasis on protein to the reliability and consistency of our proven sires as well as advancements in polled, this conversation covers the trends, bulls, and strategies that matter most right now.
