Through remarkable advancements in genetic testing and data-driven strategies, McCarty Family Farms are setting new standards in productivity, quality and sustainability.
The dairy industry is experiencing an exhilarating transformation, driven by an unprecedented demand for protein across the globe. Gregg Doud, president of the National Milk Producers Federation, captures this phenomenon aptly, describing it as a pivotal moment for dairy.
“Everywhere I go, I tell people we’re having a moment here on the dairy-side of the equation,” he says, emphasizing how dairy’s protein-rich offerings, from cheese to whey, are captivating consumers both domestically and internationally.
“You can’t manage what you can’t measure,” says Ken McCarty, one of the owners of McCarty Family Farms. “In 2011, we were milking about 7,000 cows, and today we’re milking nearly 20,000 cows, and we’ve increased productivity by almost 50%.”
Enhancing Herd Health and Milk Quality
The impact of genetic advancements extends beyond productivity to significantly enhance herd health and milk quality. By leveraging genomic insights, the McCartys have reduced disease rates and improved animal welfare, leading to superior milk quality. The reduction in somatic cell count averages that now hovers around 120,000 to 180,000 is a testament to healthier herds and stringent disease management practices, exceeding customer expectations.
Feed efficiency is crucial, with feed constituting 65% of the overall budget. The McCartys focus intently on indexes such as TPI and DWP, which are critical in informing their mating and breeding strategies.
“We really focus on specific indexes, like TPI and DWP$ (Dairy Wellness Profit Index) with Clarifide Plus, and those are really the kind of driving indexes behind our mating and breeding strategies,” he says.
Dan Weigel, a geneticist at Zoetis, has worked closely with McCarty Family Farms over the years, helping guide their genetic testing program and strategy. Weigel says McCarty’s dedication to improving life for both cows and employees reflects their continuous pursuit of optimization.
Strategic Breeding for a Better Future
Strategic breeding at McCarty Family Dairy not only caters to the global demand for protein-rich diets but also aims at creating an environmentally sustainable future. While butterfat can be nutritionally altered more easily than protein, the dairy focuses on enhancing protein content through genetic selection. This approach is designed to reduce carbon footprints by optimizing feed usage and production.
“Genetically, I think we all can recognize that it’s easier to drive butterfat through diet than it is to drive protein through diet. So, protein is really a major focus in our genetic planning, because it is so much harder to drive from a nutritional perspective,” McCarty says. “And what we’ve poured into our cows, from a genetic perspective, has shown up in the bulk tank.”
The McCartys are consistently hitting nearly 7.5 lb. of components per cow, with their dairies in Kansas and Nebraska averaging 3.35% to 3.4% for protein.
“And that is on high-producing Holstein animals,” McCarty adds. “We have the luxury of having a milk processing plant between us and our customer, so not only do we see the on-farm productivity, but we see the enhancements in terms of efficiency in our processing plant. Higher component levels milk that just drives throughput and efficiency in our processing plant as well.”
Partnership and Collaboration
The McCartys success story is also a narrative of collaboration. Strong outside partnerships, such as Zoetis team support for on-farm data analysis and genetic testing strategy, help drive holistic improvement.
“When our customer wants something, they want it now, and we position our herds to deliver,” McCarty says.
Their ability to transition farms efficiently reflects a deep pool of data and tailored herd profiles.
“We have to position our herds to deliver what our customer wants,” he adds, noting that 88% of their births are A2A2. “We have the ability today to transition farms quickly. We have that data, and we have the herd profile to be able to do that.”
High-productivity breeding strategies directly benefit animal welfare, reducing carbon emissions and aligning with stringent brand ethics.
“Breeding for high health animals has a direct positive benefit, not only on our bottom line and the productivity of our cows, but in terms of brand risk management,” McCarty says. “The single largest thing we can do to drive down our carbon footprint is to increase output. So, all of those things come from a sharper and better breeding strategy.”
Pioneering Toward Tomorrow
A data-driven approach has set an inspiring precedent at McCarty’s Rexford dairy, proving managing dairy farming no longer relies on intuition alone. Data integration empowers farmers to make informed, objective decisions, boosting production and laying the foundation for sustained long-term improvements.
McCarty’s Rexford dairy is proof positive that milking 10,000 cows averaging over 102 lb. of milk a day shows that with the right management and the right facility, along with the right genetics, the future potential is unlimited.

“We’re very emotional guys, but we try to minimize the impact that our emotions have on our farm,” McCarty says. “So, we try to be very data driven. Genomic testing is a prime example of that.”
According to Weigel there is no one-size-fits-all prescription for making improvements on dairies.
“However, data makes a difference and using data that you can glean from your farms or from DHIA or genomic testing and allowing that to help guide you, you can’t go wrong with that,” he says. “As demand grows, so does the value of precision. Data-informed decisions are what drives us forward. That’s been a huge piece to improvements in the dairy industry over the past decade.”
Innovation at farms like McCarty’s proves that data matters, guiding improvements and empowering farmers to drive the dairy industry forward into a new era of excellence.
