Advancements in genomics are opening new avenues for dairy profit.
Dairies need pregnant cows to keep their parlors filled and the milk trucks rolling. Beef feedlots need reliable year-round sources of feeder cattle to keep processing plants humming along. Today, with advancements in genomics and animal science, both needs can be met in different ways.
The first ever Beef on Dairy Symposium, a daylong event held in conjunction with the 2021 Beef Empire Days in Garden City, Kan., brings dairy farmers and cattle producers together to learn about new ways to add value to dairy cow pregnancies.

The use of terminal cross breeding is not new, explains Justin Waggoner, Kansas State University beef specialist. The use of sexed beef semen on dairy cows has been in practice for many years, but with more genomic information available to dairy producers, the matings of beef bulls to dairy cows doubled from 2015 to 2019, he says.
CATTLEMAN TO CATTLEMAN: Dairy farmer Gary de Graaf, owner of Jer-Z-Boyz Ranch, Pixley, Calif., talks with Sam Hands, owner of Triangle H Feedyard, Garden City, Kan., about pens of HerdFlex cattle finishing on feed. Dairy producers and cattle feeders are working together to bring more value to calves from dairies in the beef market.
The National Association of Animal Breeders says there are potentially 1.6 million to 2 million beef-dairy crossbred calves that will be born in 2021 — that’s just 2% of the entire calf crop of the U.S., Waggoner says. And it’s important to note that these calves aren’t displacing any beef cattle; rather, they’re displacing the dairy calves that would have already been entering the beef production stream.
“The concept of terminal crossbreeding is not new, but what has changed, I think, is the focus within the dairy industry on really improving the quality of those crossbred animals,” he says. “Both from a carcass standpoint, and from a growth and genetics standpoint.” Beef-dairy crossbred calves can bring $50 to $175 per head more than purebred dairy calves.
Waggoner calls these calves the “2.0 version” of the beef-on-dairy cross. As the practice becomes more widely accepted, it’s going to rely on data-sharing from feedyards back to the dairies where these cattle originate.
The next step
Crossbred beef-dairy calves are one thing, but what if dairy producers started transplanting beef cattle embryos in their dairy cows to result in a purebred beef calf to market? That’s the question that Chris Sigurdson, general manager of the Minnesota Select Sires Cooperative Inc., and others at Select Sires started asking themselves a few years back.
COMPOSITE CATTLE: In the feeding trial at Triangle H Feedyard, Garden City, there is a pen of beef-dairy crossbred cattle on feed alongside two pens of HerdFlex beef embryo transplant cattle. The composites had an average daily gain of 3.63 pounds, while the HerdFlex pens had average daily gains of 4.09 and 3.13 pounds.
“We started to explore what might be the next opportunity for them because of their successes as dairymen and their ability to have extra pregnancies. What else could we do with those pregnancies? And that’s where the idea for HerdFlex was really founded to use embryo transfer [ET],” Sigurdson says.
Select Sires has been the exclusive provider of beef embryos produced by SimVitro, a Simplot company for many years. In March 2020, Select Sires launched the brand name of HerdFlex beef embryos with SimVitro. The company started with a commercial trial on five Minnesota dairies, with calves finishing at Triangle H Feedyard, Garden City, Kan.
“We’re using modern embryo technology and dairy production systems’ existing assets,” Sigurdson says. “This is a beef production strategy designed to maximize calf value. Dairies contribute their extra pregnancies, calf-raising expertise and year-round production system.”
Sigurdson says the HerdFlex beef embryos are created using Simplot genetic recovery oocytes harvested from commercial black Angus-based dams, which are then matched with Select Sires Elite Proven Sires. The goal is a viable embryo that can be implanted in a dairy cow with dominant traits from the elite sires for calving ease, growth, dry-matter intake and more.
Initial results
Of course, the entire supply chain needed to find value in these animals to compensate the dairies for their investment in making these calves, Sigurdson says.
