Wisconsin fell below 5,000 licensed herds on August 1. Federal payroll data shows what that thinning costs on a 120-cow milk check — and it depends on which county line you farm inside.

Clark County, Wisconsin had 609 licensed dairy herds on August 1, 2026 — more than any county in the state, according to USDA’s National Agricultural Statistics Service working from the Wisconsin DATCP producer license list. The average Clark producer paid 44¢ per hundredweight to move milk.

In Juneau County, 36 herds were left. The average Juneau producer paid $1.2898.

Same state. Same month. Same federal study. On a 120-cow herd shipping 70 pounds a day, that’s roughly $26,000 a year in difference — before anyone makes a single decision about feed, labor, or debt.

Statewide, the count just crossed a line few expected this decade: 4,991 licensed dairy herds on August 1, down from 5,222 twelve months earlier, and the first time on record below 5,000.

The Milk Stayed. The Farms Didn’t.

Run the division and each of Wisconsin’s 4,991 remaining herds now moves about 6.6 million pounds of milk a year. That’s our own arithmetic — cow inventory times yield, divided by herd count — not something NASS or DATCP publishes. They report the three series separately.

The drop underneath it is well documented. Wisconsin had 7,292 licensed herds in January 2020. It has 4,991 now — a 31.6% decline in six and a half years while cow numbers held near 1.29 million and average production climbed to 25,599 pounds per cow.

The cows didn’t leave with the farms. The trucks just have fewer driveways to spread a load across — and that’s where the hauling math starts.

Two Auctions, and What the Record Actually Says

On September 30, 2025, the Downing family of Wonewoc sold their dairy cattle. The Gavin Bros Auctioneers listing says it flatly: they’d “sold their dairy cattle and are quitting farming.” Seven months earlier, Winkel Highland Dairy Farm near Elkhart Lake closed out its equipment in a retirement auction dated April 8, 2025.

That’s the whole public record on both. Farms exit for retirement, succession, health, a good offer, a son or daughter who wants something else — none of which makes it onto an auction bill. We don’t know why either family stopped milking, and neither does anyone else outside those two kitchens.

Geography put them in different positions, though, and that part is documented. Wonewoc sits in Juneau County, where the average producer paid $1.2898/cwt. Elkhart Lake sits in northwestern Sheboygan County — 78 licensed herds, but an average hauling charge of just 48¢, well under the state average. Whether either number had anything to do with either decision, the record doesn’t say.

Not Everyone’s Leaving

Miltrim Farms went the other direction. The Athens operation in Marathon County milks 3,100 cows and crops 5,100 acres solely for the dairy — split between 1,800 cows on 30 Lely A5 robots and the balance through a conventional double-24 herringbone parlor. Eighteen robots went in during 2019; twelve more followed in 2023.

The farm was established in 1988 by Scott Trimner, Tom Mueller and Martin Mueller, and now sits with the third generation — David Trimner and his wife Jessica Pralle-Trimner, who manages the dairy, alongside Andy and Jenny Miller. They bought it from the previous generation in summer 2024.

Co-owner David Trimner put the logic plainly to Xcel Energy in January 2026: “We don’t get to decide what we sell our milk for. It’s kind of based on the general market. And so you have to be very efficient with everything that you do.” That’s a long way from a 150-cow tiestall. It shows where capital’s flowing, not a template you can lift.

Statewide, the financial pressure has sharpened. Wisconsin’s Chapter 12 farm bankruptcy filings went from two in 2023 and two in 2024 to 16 in 2025, per U.S. Courts data reported by Wisconsin Public Radio. Nationally, Chapter 12 filings rose 46% that year with the Midwest leading. Those are 16 specific cases with court files behind them. For operations weighing the decision now, the timing gap between a planned dispersal and a forced one gets decided years ahead of the auction.

What Do Wisconsin Counties Actually Pay to Haul Milk?

There are two ways to average a county, and the difference matters more than you’d think. The simple average treats every farm equally; the study’s own footnote says it “increases the likelihood that it approximates a typical dairy farmer’s average hauling charge.” The weighted average weights by pounds shipped, so a couple of large farms can drag a county’s number way down. If you’re mid-size, the simple average is the one that looks like your milk check.

Herd counts: USDA NASS, Wisconsin Dairy Producer License list, August 1, 2026. Hauling: Federal Milk Market Administrator Staff Paper 25-03, May 2025. Annual figures assume 70 lbs/cow/day — that assumption is ours.

Sheboygan is the honest complication. Only 78 herds, but 48¢ — because it sits close to processing and population, and the study lists distance to plants and handler competition right alongside farm concentration. Density isn’t the only variable. It’s just the one that changes when your neighbors quit.

THE DENSITY EQUATION

The five factors the federal study says set your rate:

• Producer pounds
• Distance to plants
• Distance to population centers
• Competition among handlers
• Concentration of dairy farms in the local market

What that looks like on the ground:

Wisconsin pays the lowest weighted hauling charge on the Upper Midwest order: 47.1¢, against 50.9¢ order-wide, 70.4¢ in Iowa and 80.4¢ in Illinois. The study credits the state’s “high number of farms generally in close proximity to high demand areas.”

That advantage rests on farm count and proximity to processing. One of those fell by 231 in twelve months.

Why Fewer Neighbors Can Raise Your Deduct

Here’s what happens when your neighbor sells. The truck still runs the route. It just fills slower, and the study doesn’t hedge on who carries that: “hauling costs are higher for smaller farms, given the increased number of stops in order to fill out a load.” Most Upper Midwest handlers charge a flat hauling fee regardless of volume. Fewer pounds, same fee, higher cost per hundredweight.

You can see it in Wisconsin’s size brackets. Producers shipping under 50,000 pounds a month paid $1.0433/cwt in May 2025. Producers shipping 5 million pounds or more paid 33.3¢ — right around a third of that. Distance is the other half of the equation, and we’ve watched what happens to a route when a plant closes and the milk suddenly has to travel.

Where the plants get built decides who has leverage, which is why processor investment patterns matter as much as herd counts.

Then there’s fuel, which behaves oddly here. Midwest diesel fell 7.68% between May 2024 and May 2025, while average hauling charges moved just −0.84% over the same stretch. Fuel is one input among several — labor, equipment, and insurance all move too — and the study doesn’t pin that gap on any single cause. Worth asking your co-op about anyway.

Is Your Herd Size Even the Right Benchmark?

Wisconsin’s average herd is around 260 cows. Milking 120 or 200, it’s easy to read that as falling behind.

Don’t. The 2022 Census of Agriculture puts the median Wisconsin dairy farm in the 50-to-99-cow bracket, where the bracket average was 67 cows — against a state average of 203 that same year. The average sat roughly three times higher than the midpoint of the bracket the median farm falls in. A handful of very large operations drag it up: 61.8% of Wisconsin dairy farms milked fewer than 100 cows in 2022, and together they held 12.9% of the state’s milk cows. The 217 farms above 1,000 head — 3.5% of operations — held 36.2%.

So at 120 or 200 cows, you’re not behind the typical Wisconsin dairy farm. You’re well ahead of it. (One caveat: the Census counts farms with milk cow inventory, a slightly different universe than DATCP’s licensed-producer list, so the two counts don’t line up exactly.)

That loops straight back to the truck. A 67-cow herd at 70 lbs/day ships about 143,000 pounds a month, landing in the 100,000–249,999 bracket at 60.4¢/cwt — roughly 28% above the state weighted average. On 17,200 cwt a year, that’s about $2,280 more than the state-average farm pays for the same service. The median Wisconsin dairy farm is already sitting on the wrong side of the hauling curve.

Three Things to Run Before Your Next Budget Meeting

Action 1 — Audit your milk check against your county. Do this within 30 days.

What to do: Pull Staff Paper 25-03, free at fmma30.com. Find your county in the Wisconsin table. Use the simple-average column. Compare it against the hauling deduct on your last milk check.

What it tells you: Whether you’re paying a typical rate for your area or an outlier rate. If you’re materially above your county’s simple average, that’s a specific question for your field rep backed by federal data — a data point, not a complaint.

The limit: Counties with fewer than three producers are restricted from the data entirely. And where simple and weighted diverge sharply, one large farm is doing the work — Adams County reads $0.9173 simple against $0.0671 weighted.

Action 2 — Find the volume cliff nearest you.

What to do: Calculate your monthly pounds shipped. A 250-cow herd at 70 lbs/day ships roughly 532,000 lbs a month — just under the 600,000 lb line where Wisconsin’s rate drops from 63.2¢ to 53.2¢/cwt.

The math: Add about 32 cows and you cross it. Total annual hauling falls from roughly $40,400 to $38,400 — while shipping more milk.

The limit: Not a reason to expand on its own. But it’s a real line most expansion pro formas leave out entirely, and it can move a marginal project.

Action 3 — Stress-test new debt against your region’s ceiling.

What to do: Financing a barn or robots? Run the pro forma at $1.29/cwt alongside your current rate.

The math: Against Wisconsin’s all-milk price of $17.70/cwt in February 2026 — the most recent state figure NASS has published — Clark’s 44¢ is 2.5% of gross, the state simple average of 70¢ is 4.0%, and Juneau’s $1.29 is 7.3%. Prices have recovered since; the U.S. all-milk price was $21.10/cwt in June 2026, pulling those shares to 2.1%, 3.3%, and 6.1%.

The trade-off: This can make a sound project look worse on paper. It also means you find the sensitivity before your lender does. While you’re at it, price the permit timeline in before you finance the barn.

And three more lines belong in that same pro forma. Hauling isn’t the only cost that behaves differently at your scale, and if you’re already running the sensitivities, run these alongside it.

The first is labor, which doesn’t shrink with effort. USDA Economic Research Service puts total labor — hired plus unpaid family — at $13.18/cwt for herds of 10–49 cows, $5.12/cwt at 100–199 cows, and $1.85/cwt on farms with 2,000 or more (ERR-274, MacDonald, Law and Mosheim, 2020, ARMS 2016 data, national scope). Note the vintage — directionally solid, but not 2026 dollars. The full breakdown by herd-size band is here.

The second is the zero-deduct farms that skew every average you’ll read. 327 Wisconsin and Michigan UP farms showed no hauling deduction on handler payroll in May 2025, usually because they self-haul or use a third party outside the payroll system. Strip those out and Wisconsin’s weighted average jumps from 47.1¢ to 60.1¢/cwt. If you pay a deduct, the higher number is closer to your world.

The third only matters if exit is genuinely on the table inside five years — but if it is, start the tax and succession conversation now. The equity difference between a planned dispersal and a forced one gets decided years ahead of the auction, not weeks.

Key Takeaways

• Can’t recall your hauling deduct? That’s this week’s phone call, not next quarter’s.
• County herd count dropped since 2024? Treat hauling as a variable cost in this year’s budget, not a fixed one. The NASS county table publishes annually and it’s free.
• Comparing yourself to a county average? Use the simple-average column. The weighted column describes the county’s biggest shippers, not you.
• Two neighbors gone off your route since 2024? Run your annual cwt against both your current rate and your county’s simple average. That difference is your exposure.
• Milking 50 to 99 cows? You’re the median Wisconsin dairy farm — and the median already pays roughly 28% above the state’s weighted average.
• Shipping just under 600,000 lbs a month? Price out what crossing that line does to your total hauling bill before you rule out expansion on cost alone.
• Would 44¢ to $1.29/cwt break your debt service? Hauling isn’t the problem. The margin structure is, and you’ve got more options now than you will later.

Go Count the Farms on Your Road

Count how many are still shipping within ten miles of your driveway, then count how many were there five years ago.

That number tells you more about next year’s milk check than the state herd count ever will. Wisconsin’s cheap hauling is built on farm density and processor competition, and both are moving. The question worth raising at the next co-op meeting isn’t whether the state count keeps falling — it’s what your route looks like when it does.

We’re testing the density-versus-cost relationship across all seven Order 30 states, with the outliers explained instead of smoothed over, for an upcoming Bullvine Weekly. That’s where the full county tables and the sensitivity model will live.

Methodology note: County herd counts come from “Wisconsin Milk Cow Herds by Type of Milk Produced, Number and Percent by County, August 1, 2026,” USDA National Agricultural Statistics Service, based on the Dairy Producer License list, Division of Food Safety, Wisconsin DATCP. Herd-size distribution comes from the 2022 Census of Agriculture, Wisconsin, Table 17, USDA NASS; the median is derived by cumulative farm count across published brackets and falls within the 50–99 cow class — NASS does not publish a median. Hauling charges come from “Milk Hauling Charges in the Upper Midwest Marketing Area, May 2025” (Staff Paper 25-03), by Dr. Areerat Kichkha, Agricultural Economist, Federal Milk Market Administrator’s Office, Minneapolis, September 2025, covering 7,805 producers, 5,073 of them in Wisconsin. Herd-count and hauling datasets are fifteen months apart. Milk-per-herd figures are The Bullvine’s own calculation. Labor figures are USDA ERS ERR-274 (MacDonald, Law and Mosheim, 2020), ARMS 2016 data, national scope. Wisconsin all-milk price from USDA NASS Agricultural Prices via the DATCP Wisconsin Farm Reporter. Miltrim Farms details come from the farm’s own published history, American Dairy XPO 2026 speaker materials, Farm Progress (2023), and a January 2026 Xcel Energy feature. The auction records referenced are public listings; they state no reason for either exit, and no financial circumstances of either family are known to us or asserted here. Herd-size equivalents assume 70 lbs/cow/day and are ours. Counties with fewer than three producers are restricted in the federal data and excluded here. All figures USD.
