Drylot Cow-Calf: Costs, Pen Space and Hay Needs Without Pasture

By the XES Netting team — bale net-wrap manufacturer · Updated October 7, 2026 · ~17 min read

Drylot cow-calf production — keeping cows and their calves in a pen on harvested feed instead of on pasture — is back in the farm-forum conversation. Pasture rent and land prices have climbed, calves are worth more than they have been in years, and plenty of row-crop farms that would like a few cows have no grass at all. Done well, a drylot can hold a herd together through a drought or let a farm add cows without buying land. Done on optimistic math, it turns a winter feed bill into a 365-day feed bill.

This guide is for cow-calf producers weighing a drylot against renting or buying pasture, and for row-crop farms thinking about adding cows. It is not a ration, facility design or veterinary recommendation; work with a nutritionist, your county Extension office, a veterinarian and your state environmental agency before you build or fill a lot. XES manufactures bale net wrap, and stored forage is the backbone of most drylot rations. We compared 26 archived AgTalk discussions about drylot and confinement cows (298 posts, 2022–2026) with Extension guides from North Dakota State, Nebraska and Kansas State, a controlled drylot-versus-pasture trial and the federal permit rules.

Why farmers are drylotting cows again

The reasons producers gave on AgTalk in 2025 match the ones Extension guides list: land, drought and labor. North Dakota State University’s Drylot Beef Cow-Calf Production guide (AS974, revised March 2023) says drylot production “is an option during a drought, or when expanding a cow herd or an operation has experienced a loss of pasture resources,” and that it may let new producers start a herd without a large investment in land.

"Not year round. But been dry lotting pairs since 2012 drought… Has proven to work very well. Pasture rent and freight has gotten out of hand. Can drylot cheaper."

— ahay68979, Saronville NE · AgTalk thread 1217721

Land is the other driver. One producer who hauls cows 60 miles to grass summed up the row-crop side of the problem: it is “hard to use several acres per pair of 10-15k per ac land for cows.” An Iowa farmer feeding 60 head in a lot alongside a hog operation said drylotting “helps me alot with time management and feeding fast everyday.”

"I think labor efficiency would go way up when most of the cattle are 100 yards from the silage pit."

— 7210jd, Nw mo · AgTalk thread 1212491

The longer-serving voices in those threads added a warning about timing. A southwest Minnesota producer pointed out in 2023 that cow-calf confinement was “all the rage” in 2013 and mostly gone by 2015, and told anyone running numbers to “pencil in 5 years of $700 calves and 50 cent cull cows.”

"That topic seems to come up when cattle prices are high and go away when prices are low. It probably works as long as feed is cheap, but bedding will be pretty significant."

— Haleiwa, West Chazy, New York · AgTalk thread 1217721

The University of Nebraska–Lincoln’s Management Considerations for Beef Cows in Confinement (G2237) frames confinement as an alternative to partial or total herd liquidation when forage is short or too expensive, and adds a caution worth reading twice: “Keeping cows in confinement 12 months out of the year may not be an economical management strategy. However, partial confinement may be a viable option when pastures need deferment or forage is not available.”

What the research says about drylot vs pasture

The cleanest comparison we found is a 2021 summer trial by University of Illinois and Western Illinois University researchers, published as a Journal of Animal Science abstract (Hofer and others). They split 108 spring-calving Simmental × Angus pairs, about 77 days after calving, between drylots and rotationally grazed pasture for 110 days. Drylot cows were limit-fed corn silage, dried distillers grains, cornstalks, cracked corn and a supplement.

Nebraska Extension’s drylotting guide reaches a similar overall verdict, that data suggest cow and calf performance is similar whether pairs are drylotted or on pasture. A Nebraska producer who custom-drylots pairs went further in 2024, reporting calves “actually bigger then calves on grass” and better breed-back; that is one operation’s experience, and the Illinois trial found no pregnancy difference. What the research does make clear is the trade: heavier, better-milking cows in exchange for more lameness and a feed bill every single day.

Kansas State University’s Beef Cattle Institute describes the economics the same way in The Confined Cow-Calf System (2021). Limit feeding a high-energy byproduct diet cuts the cow’s maintenance energy requirement by 20 to 40% compared with a low-energy forage diet fed free choice, but “harvesting and delivering feed to the cow rather than the cow harvesting feed herself always adds cost,” and studies show net returns fall as the confinement period gets longer.

The daily cost worksheet

Drylot plans usually go wrong in the multiplication, not the ration. When a north central Missouri producer posted in 2025 that feed and yardage would run under $1,200 a year at about $2 a day in feed, the first reply did the arithmetic:

"Well, you're missing that $2/day is only $730. Even $2.99/day is only $1091. So sharpen your pencil. LOL"

— tmrand, Southeast Colorado · AgTalk thread 1212491

The fix is to price every input per head per day, then multiply by 365 once at the end. The table fills each line with numbers producers actually posted on AgTalk between 2023 and 2026. They come from different farms, regions and years, so treat them as a starting point, not a budget.

Add the first four lines and the illustration lands at about $2.85 a day, roughly $1,040 a year, with a new barn, or about $2.47 a day, roughly $900 a year, in facilities that are already paid for — before health, death loss, bulls and manure. For comparison, custom grazing quotes in an October 2023 AgTalk thread ran from “$1.50 per day per pair” in Saskatchewan to “$2.25 to 2.50/pair/day” in northeast Nebraska, which is the same ceiling producers describe in our pasture rent rates guide: past about $2.50 a pair per day, a drylot starts to look cheaper. Custom drylot operators quoted $2.75 a day for pairs including yardage, and $3.00 to $3.10 a day for dry cows, in August 2025.

"Don't think I would do it if I had to build new facilities, just using the barns that were there for when dad milked. It would definitely not be "worth" it if you added a barn payment."

— mn_feeder, MN · AgTalk thread 1098529

That is the pattern the arithmetic predicts. With paid-for facilities and cheap feed, a drylot can sit right at the price of rented pasture; a new barn payment usually pushes it past. Run the worksheet with your own feed prices and a realistic yardage figure — your time has a price even if no one sends you a bill.

Pen space, bunk space and water

Space recommendations vary with soil and drainage, and the published figures are minimums for well-drained ground. This table collects them in one place.

Two details from the NDSU guide are easy to miss. Feeding on the ground in a pen is not recommended, because feed gets fouled with manure and waste climbs; and very large dirt lots let more dust blow, which the guide flags as a pneumonia risk for baby calves. For the surface under the bunks and bale feeders, our cattle feeding pad guide covers gravel versus concrete and scraping frequency.

Producers building bedded-pack barns in a 2023 thread were working with roughly 75 to 100 square feet per cow under roof and a scrape alley at least 12 feet wide, or 14 feet where a skid steer has to turn. Those are farmer rules of thumb for covered packs, not Extension standards, and they are not comparable to the open-lot figures above.

Full-fed hay or a limit-fed ration

A cow that eats free-choice hay in a pen eats a lot of hay. Most of the cost savings in confinement research come from limit feeding: meeting the cow’s energy and protein needs with a diet smaller than she would eat if given all she wanted. Nebraska’s G2237 describes an energy-dense, protein-adequate diet fed at less than 2% of body weight on a dry-matter basis, built on the cheapest regional feeds — crop residues and poor-quality hay balanced with silage, grain or byproducts — and says the data suggest limit-fed rations are the most economical strategy for confined cows.

• Keep a forage floor. Nebraska Extension’s rule of thumb is at least 0.5% of body weight as forage dry matter to keep the rumen healthy: 6 lb of dry matter, or about 7 lb of 85% dry-matter hay, for a 1,200-lb cow. NDSU raises the hay minimum to 0.75 lb per hundredweight in extreme cold.
• Expect hungry-acting cows. Cows adjust to a limit-fed diet over a week to 10 days. Feed at the same time daily and spread the ration along all the bunk space so timid cows get their share.
• Limit hay by time if you lack a mixer. In a University of Illinois study summarized by Nebraska’s BeefWatch, cows with 3 hours a day at a round-bale feeder ate 17 lb of hay dry matter, against 34 lb for cows with 24-hour access, and waste dropped when access was held to 14 hours or less. That hay was high quality; test yours before you restrict it.
• Grain can replace hay. In an Ohio State study cited in the same article, cows fed about 11 lb of whole shelled corn, 2.5 lb of pelleted supplement and 2 lb of hay (dry matter) through late gestation and early lactation did as well afterward as cows on free-choice hay, which ate twice as much feed.
• Watch distillers limits. NDSU puts the dietary sulfur ceiling at 0.3% to 0.5% of dry matter, counting sulfate in the water, and fat at no more than 5% to 6% of intake. Nebraska’s G2237 adds limestone when distillers grains are fed to hold a calcium-to-phosphorus ratio of at least 1.5:1.
• Deliver mineral, vitamins and monensin in the feed. Cows on limited hay tend to overeat free-choice mineral, and monensin has to be fed daily with at least a pound of feed per head. Nebraska’s mineral guide also warns that cows confined long-term have little stored vitamin A and suggests at least 100,000 IU a day; our guide to mineral for cattle in winter explains why stored feed runs short.
• Feed the calf too. G2237 warns that “if the calf’s ration out of the bunk is not included, the dam will be underfed.” Nebraska Extension estimates a 200–300 lb calf eats about 1% of its body weight in dry matter.

The rations producers described are built on cheap energy. One Nebraska custom feeder runs cows in good condition on 95% rye silage and 5% wet distillers grains, adding about 10 lb of corn for thin cows; a northeast Nebraska producer held 35 extra pairs on roughly 25 lb of corn silage, 15 lb of alfalfa and 10 lb of cornstalks; a 2026 ration for older pairs was 57% corn silage, 5% dried distillers and 38% grass-alfalfa hay. Rye and triticale cut for silage or baleage show up again and again — see our guides to baling cereal rye for forage and triticale baleage.

"You can't starve a profit out of cows."

— ahay68979, Saronville NE · AgTalk thread 1149445

If hay or baleage goes through a TMR mixer or a bale processor, count the processing too. A northeast Iowa producer figured grinding at about $11 a bale locally, so grinding a hay bale and a stalk bale to mix together added $22 to a stalk bale “worth say $35” — about $57, roughly what a bale of hay costs if you shop around. And take the net wrap off first: our guide to grinding bales with net wrap on explains why chopped wrap ends up in the rumen, where cattle cannot digest it.

How many round bales a drylot cow needs

On pasture, hay covers the winter. In a drylot, harvested feed covers every day, so the bale count changes completely. The arithmetic is the same one our how much hay does a cow eat guide walks through step by step:

Bales offered per cow per year = (lb of hay dry matter eaten per day × days) ÷ (bale weight × bale dry matter) ÷ (1 − feeding loss)

The table runs that formula for a 1,300-lb cow and 1,200-lb bales at 85% dry matter (1,020 lb of dry matter per bale), across the hay-waste results from an Oklahoma State feeder trial reported in Nebraska’s BeefWatch: 5.3% for a cone feeder with a sheeted bottom, 13% for a sheeted-bottom ring and 20.5% for an open-bottom steel ring.

XES calculation. The 2.0% intake is an illustration inside the measured and planning figures our intake guide discusses, not a prediction for your cows; storage loss before feeding is extra, and the limit-fed row covers hay only — the rest of that ration comes from silage, byproducts or grain.

For a 50-cow lot, that is the difference between roughly 535 bales a year on full-fed hay in sheeted rings and about 134 bales when hay is held to the forage floor. Calves eating at the bunk add to both numbers, and bedding adds its own line: at Nebraska’s long-run reference of about 4 lb a head a day, 50 head bedded for 150 days use roughly 30,000 lb, or about 25 bales of 1,200 lb. Store those bales well — every pound lost in the stack has to be replaced at the bunk — and plan wrap from your own baler’s results with the method in our net wrap per bale guide.

Calves, mud and feet

Calf health is the warning that came up most in the forum threads, and it lines up with what Extension guides describe.

"Calves get 'bored' and will eat manure in a lot which is a scours risk. When it rains the lot turns to mud, which is hard on calves"

— HuskerJ, East of Broken Bow · AgTalk thread 1157971

"Just remember sunlight and dry is a calfs friend. dank and wet is not."

— dt4020, Fairbury, NE (Southeast) · AgTalk thread 1098529

NDSU’s guide says a poorly designed or poorly managed drylot “can be a hot, crowded, dusty or muddy, fly-infested environment,” that a well-drained or paved site with a southern exposure and regular manure removal reduces stress, and that animal density spreads disease faster, so prompt treatment and a vaccination plan from your veterinarian matter more than on pasture. Producers who calve in the lot described bedding it down well, giving calves a creep gate to a quiet corner and moving pairs out to grass or a clean field anywhere from one day to a week after calving.

Mud is the other recurring problem. A northeast Missouri producer who argued for overstocked pasture over a pen put it plainly:

"A dry lot will have its issues with mud season and rain all the time too. Fresh bedding, scours, scraping pens, etc."

— cows-n-crops, NEMO · AgTalk thread 1212491

Nebraska’s 2024 BeefWatch article on bedding cattle yards recommends scraping at least weekly during cold spells and bedding right after scraping. Building the base of a bed pack takes at least 12 to 14 lb of bedding per head, double that if the pen is already deteriorating, and about 4 lb per head per day over the long run. Those are feedyard figures; heavier cows with calves will not use less. Feet are the last piece: the Illinois trial’s 33% lameness-treatment rate in drylot cows is the number to plan around, with clean, dry footing at bunks and waterers and quick treatment of foot rot.

Permits and manure

A drylot can turn a farm into a regulated feeding operation. Under the federal Clean Water Act rule at 40 CFR 122.23, a lot is an animal feeding operation when animals are confined and fed for 45 days or more in any 12-month period and crops, vegetation, forage growth or post-harvest residues are not sustained over any part of it in the normal growing season. A large concentrated animal feeding operation starts at 1,000 cattle, and the rule specifically counts cow-calf pairs. States run their own permit programs and thresholds, which can be stricter, so Nebraska Extension advises checking with your state environmental agency before you fill a lot.

Manure is the other side of the ledger. NDSU estimates a beef cow produces about 63 lb of fresh manure a day, and drylot cows on paved lots from May 1 through September 15 accumulated 1.75 to 2 tons of manure dry matter per cow. Open-lot manure at 50% dry matter carries roughly 21 lb of total nitrogen, 14 lb of phosphate (P₂O₅) and 23 lb of potash (K₂O) per ton, so test it before you spread. Hay ground is a natural home for it; our guide to manure on hay ground covers rates and timing.

Partial drylot: the version that usually pencils

Very few of the producers who reported success in those threads kept cows in a pen 365 days a year. Most used the drylot for part of the cycle and let cows harvest something else the rest of the time:

1. Fall calving plus stalks. The Nebraska custom feeder quoted above calves in August and September, moves pairs to an irrigated feed field a few days after calving, grazes cornstalks until mid-January and drylots only until weaning.
2. Drylot from winter until grass. NDSU notes that many producers already hold cows in a drylot through winter and after calving until pastures are ready.
3. Alternating grazing and lot. One northeast Iowa producer with only half the pasture the herd needs rotationally grazes for about two and a half weeks, then feeds in a lot for two and a half weeks.
4. Overstocked pasture with bunks. Double the stocking rate, set fence-line bunks and supplement after the spring flush — with a plan for where the cattle stand when it rains.
5. Residue and stockpile first. Cornstalks and stockpiled forage are usually the cheapest feed a cow can harvest herself; see our guides to grazing or baling cornstalks and stockpiling forage for winter grazing.

"Why not just double the stocking rates of the pastures you already have? Set up fence line bunks and after the spring flush of grass, start feeding/supplementing them."

— cows-n-crops, NEMO · AgTalk thread 1212491

That matches the Kansas State finding that returns shrink as confinement gets longer, and Nebraska’s view that partial confinement is the viable version. Price each month in the lot against what that month on grass or stalks would cost, and keep the lot for the months when it wins.

Frequently asked questions

How much does it cost to keep a cow in a drylot per day?

Producers posting on AgTalk in 2025 and 2026 reported about $2 a day for feed, yardage of 30 to 40 cents a day at custom lots, and $2.75 to $3.10 a day all-in for custom drylotting. Your cost depends on feed prices, bedding, facilities, labor and health, so build the daily stack from your own inputs.

How much space does a cow-calf pair need in a drylot?

North Dakota State University recommends at least 500 square feet per pair, with 800 to 1,000 square feet better on poorly drained ground, and no more than 60 to 80 pairs per pen. Plan 26 to 30 inches of bunk space per cow for limit-fed rations, plus a creep area where calves can get away.

How much hay does a drylot cow eat?

Full-fed on hay alone, a 1,300-pound cow eating 2% of her body weight needs about 26 pounds of hay dry matter a day, roughly 10 to 12 round bales a year after feeding loss. Limit-fed rations hold hay near 0.5% of body weight and supply the rest with silage, byproducts or grain.

Is drylotting cows profitable?

It can be when pasture is scarce or costs more than about $2.50 a pair per day, feed is cheap and facilities are already paid for. Kansas State University notes that net returns fall as the confinement period lengthens, so partial drylot systems usually pencil out better than keeping cows in a pen year-round.

Do you need a permit to drylot cattle?

Possibly. Under federal Clean Water Act rules, a lot where animals are confined and fed 45 days or more in a year without vegetation is an animal feeding operation, and 1,000 or more cattle, including cow-calf pairs, makes a large CAFO. States set their own permit thresholds, so check with your state agency first.

The bottom line on drylot cow-calf

Drylot cow-calf works when the arithmetic works: a full daily cost that beats the pasture you could rent, a limit-fed ration built on cheap energy with hay as the forage floor, enough pen and bunk space, and a plan for calves, mud and manure. Start with partial confinement, use facilities you already own, and price every input per head per day before the first cow goes in the pen. Whatever the ration, a drylot runs on stored forage, and round bales wrapped in XES bale net wrap hold their shape from the stack to the feeder.

Research note: We screened all 30 archived AgTalk discussions with drylot, dry lot or confinement in the title (316 captured posts) and read the 26 about beef cattle in full (298 posts, 2022–2026), plus a 2023 custom-grazing rates thread, then checked the linked Extension guides, research and federal rule on October 7, 2026.
