Not long ago, Jerseys were gaining ground on many dairies. Strong butterfat tests and a reputation for feed efficiency made the smaller brown cows an attractive option for producers chasing component premiums. In many herds, Jerseys filled that role well, especially when milk checks heavily rewarded fat.
But the advantage that once set Jerseys apart has narrowed. Years of genetic progress have pushed Holsteins to improve components while maintaining their high production levels. As that gap closes, some dairies that once leaned into Jerseys are beginning to reconsider the role the breed plays in their herds.
Changing Views on Herd Composition
This shift is easy for Jason Anderson to spot. As a dairy consultant with Progressive Dairy Solutions, he works with dairies across the western U.S. and says herd makeup conversations are happening more often.
“Jerseys made a lot of sense when butterfat premiums were really strong and producers were chasing components,” Anderson says. “But now that Holsteins are improving components and still bringing the production, some dairies are reevaluating that balance.”
That change is showing up in herd composition in different ways. Some producers who once expanded Jersey numbers are now leaning more toward Holsteins or rebalancing their breed mix, while others are turning to crossbreeding programs.
In each case, the goal is the same: select cows that fit the environment and the way milk is paid.
Payment Signals Are Shifting
Behind many breeding decisions is a change in how milk is valued. In some regions, processors are not only reducing premiums for high butterfat but also applying deductions when fat levels run too high relative to protein.
“[Processors] have taken the premium off fat a little bit because there’s been so much of it produced,” Anderson says. “Essentially, they’re trying to bring the protein-to-fat ratio closer together.”
Protein is playing a larger role as processors adjust product mixes, shifting emphasis in how milk is evaluated.
“We’re continually trying to increase protein content,” Anderson says. “You can push protein nutritionally with amino acids, but that can get expensive. Doing it genetically is a much cheaper approach.”
Because genetic change takes time to reach the bulk tank, producers are making breeding decisions based on where they expect markets to go, not just where they are today. For many operations, that outlook is shifting herd direction away from Jerseys and toward more Holstein influence.
Those market signals are also showing up in herd economics.
“Using data from our high-producing herds within PDS, Holsteins show about a $3.20 per cow advantage in gross margin compared to Jerseys,” Anderson says. “That comparison used the Adisseo MilkPay model, assuming a Jersey at 68 pounds of milk with 5.3% fat and a Holstein at 94 pounds with 4.3% fat, while holding feed efficiency constant.”
Crossbreeding Gains Momentum
While crossbreeding is not new to the industry, interest has grown as producers look for improvements in fertility, longevity and overall herd performance.
As production levels climbed through purebred genetics, some herds began to see more challenges with reproduction, metabolic stress and cow turnover, prompting them to rethink breeding goals.
By combining breeds, producers have been able to capture hybrid vigor, which often shows up in fertility, survival and resilience. Crossbreeding can also help improve production consistency and better balance components to match today’s milk pricing signals.
Anderson says many dairies are now several generations into structured crossbreeding systems.
“About half of one of my client’s herd is crosses, F1, F2, F3s, HoJos, whatever you want to call them,” Anderson says. “Our strategy is we’re breeding these crosses back to F1 bulls, and we’re working on our fifth generation.”
The result is improved fertility and lower replacement needs as cows remain productive longer.
“When cows stay in the herd longer, that changes the economics pretty quickly,” Anderson says. “You’re not raising as many replacements, and the cows that are in the herd have already paid off their rearing costs.”
Crossbreeding can also moderate cow size, helping animals fit more comfortably into modern facilities.
“A lot of producers want a more moderate cow that still produces well but is easier to manage,” Anderson says. “You can get that balance when you start combining breeds.”
The Herd Continues to Evolve
The way producers think about breed balance is shifting, and herd makeup is changing with it. Jerseys still have a place on many farms, but their numbers may slide back in some regions as producers rethink the balance with Holsteins.
“The industry used to have a very specific picture of the ideal cow,” Anderson says. “Now producers are thinking more about what works in their system and what makes the most economic sense.”
That flexibility is reshaping herds across the country, whether through crossbreeding or more targeted selection within Holsteins and Jerseys.
A decade ago, herd dynamics looked different from what we see today. Walk through a dairy barn ten years from now and the cows may look different once again. What will stay constant is the goal behind them: building a cow that fits the farm, the market and the future.
