Highest Milk Producing Cow: Breeds Ranked by Yield

The highest milk producing cow breed in the United States is the Holstein. Cows of that breed with national milk-recording records averaged 28,023 lb (12,711 kg) of milk in a standardized 305-day lactation (twice-daily milking, mature-age basis) in 2020, against 20,931 lb for Jerseys (CDCB, national standardized averages). Yield is only one part of the answer, though. Jerseys, Guernseys and Brown Swiss give less milk but more fat and protein in each pound, and that changes which breed earns more on your farm.

This guide ranks the five best-known dairy breeds by milk yield, shows how the ranking changes when you count fat and protein, and adds a calculator so you can test your own milk price and feed cost. Numbers come from US, Canadian and university sources, and every figure carries its year.

Highest milk producing cow breeds ranked by yield

The table uses the national standardized lactation averages that the Council on Dairy Cattle Breeding (CDCB) publishes for cows with records used in US genetic evaluations. These are standardized yields for recorded cows, adjusted to 305 days, twice-daily milking and a mature-age basis, so they are higher than the actual herd-wide average for all US cows. They are not a promise for any single herd.

The table is CDCB data for calving year 2020, from the CDCB lactation averages over time. The last column adds the fat pounds and protein pounds the same tables list for each breed. Milking Shorthorn is in the table because CDCB reports it and it out-yielded the Jersey in 2020, from only 2,535 records and after a jump of about 1,600 lb on 2019, but it is not one of the five breeds covered in detail below.

Ranking at a glance

1. Holstein. The most milk and the most fat plus protein per cow. Best for: large, well-fed herds sold on volume.
2. Brown Swiss. Second for milk and third for fat plus protein, with a higher protein percentage than the Holstein. Best for: cheese milk, where protein is paid for.
3. Jersey. Lower volume, the richest milk. Best for: milk paid on butterfat and protein.
4. Ayrshire. Fourth of the five for volume, with fat and protein percentages close to the Holstein’s. Best for: herds that want Holstein-like milk components at a lower volume.
5. Guernsey. The lowest volume of the five in this table, with high fat and protein percentages. Best for: farms paid mainly on fat and protein, not on volume.

Which cow breed gives more milk: the five breeds in detail

Holstein: the milk volume leader

Holstein cows gave 28,023 lb of milk in 2020 and 1,111 lb of fat plus 882 lb of protein (CDCB). Holsteins are also the biggest group: the USDA Economic Research Service says most US dairy cows are Holsteins, a breed that tends to produce more milk per cow than other breeds (USDA ERS dairy background). In the milk-recording data Canada reports, Holstein cows gave 11,147 kg in 305 days, with 4.04% fat and 3.31% protein.

The trade-off is feed and climate. A high-yield cow needs a large, steady ration and cool, clean housing. A study of 418 herds in Costa Rica found that Holsteins lost more daily milk than Jerseys as the temperature-humidity index (THI) rose. We show those numbers further down.

Brown Swiss: high protein and a strong second for volume

Brown Swiss cows averaged 23,245 lb of milk, 4.12% fat and 3.36% protein in the 2020 CDCB tables. In Canada’s recorded herds they gave 8,858 kg in 305 days with 3.56% protein, which is above the Holstein’s 3.31%. Higher protein is useful to a cheesemaker, because protein is a main part of what makes cheese. Whether it pays depends on what your buyer pays for protein.

Jersey: smaller cow, richer milk

Jerseys averaged 20,931 lb with 4.82% fat and 3.68% protein, the highest percentages of the six breeds CDCB reports. In Canada the Jersey gave 7,282 kg with 5.14% fat in the recorded herds, and in Denmark and Sweden the breed’s recorded fat was 5.96% and 5.83% (Agriculture and Agri-Food Canada table of ICAR data). The same milk-recording tables show the Jersey far behind the Holstein for milk volume (7,282 kg against 11,147 kg), so a Jersey herd needs a milk price that rewards components.

Ayrshire: a practical all-rounder

Ayrshires averaged 20,266 lb, 3.97% fat and 3.17% protein in the CDCB tables, so their milk is close to the Holstein’s in composition but lower in volume. Canada’s recorded Ayrshires gave 8,420 kg with 4.16% fat and 3.42% protein. We found no independent study in this review that shows Ayrshires beat other breeds in poor weather or on rough ground, so treat that reputation as local farm experience, not a measured result.

Guernsey: the lowest volume, high components

Guernseys averaged 17,916 lb, 4.55% fat and 3.42% protein. That is the lowest milk volume in the CDCB table, with fat and protein percentages second to the Jersey. Canada’s recorded Guernseys gave 7,305 kg with 4.66% fat. The older claim that Guernsey milk is rich in beta-carotene has no figure in the tables used here, so we have left numbers for it out.

Milk volume versus fat and protein

The breed with the most milk is not always the breed with the most valuable milk. Where the buyer pays for fat and protein, the pounds of components matter more than the pounds of water. In the 2020 CDCB data the Holstein still led on fat plus protein (1,993 lb), the Jersey came second (1,777 lb) and the Brown Swiss third (1,738 lb). The Jersey beat the Brown Swiss on percentage but not on pounds, because the Brown Swiss gives about 2,300 lb more milk.

Milk prices differ by market. In the US, many buyers pay on components under federal or state pricing, while some pay on volume with a premium for butterfat. In Europe, milk is often paid per kilogram of fat plus protein. Check your own milk statement before you pick a breed for its percentages.

How yields have changed since 1980

Both breeds gave far more milk in 2020 than in 1980. Holstein recorded cows went from 17,566 lb in 1980 to 28,023 lb in 2020, a rise of about 60%. Jerseys went from 11,437 lb to 20,931 lb, about 83% (CDCB). Breeding, feeding and cow comfort all played a part. CDCB also says a change in how lactation records were calculated (made in 1997) explains part of the rise between 1990 and 2000, so the early years are not strictly comparable. A single new breed will not repeat this growth on your farm.

Record milk yield for a single Holstein

People who search for the highest milk producing cow often want a record. The US Holstein record for a 365-day lactation, announced by Holstein Association USA in October 2017, is 78,170 lb of milk, with 3,094 lb of fat and 2,393 lb of protein, from Selz-Pralle Aftershock 3918 in Wisconsin (Progressive Dairy, 2017). It beat a 77,480 lb record set earlier. We have not checked whether a later cow has passed it, and we do not claim a world record here.

That cow gave nearly three times the CDCB Holstein average. Records are made by the best cows, on the best days, with careful feeding and cow comfort. They show what a breed can reach, not what a herd will average (The Bullvine repeats the Holstein Association statement).

Breed yields in the US, Canada, the UK and Australia

The same breed gives different numbers depending on who counts. In the USDA NASS Milk Production tables, the 2024 annual average for all US milk cows was 24,178 lb per cow. That is lower than the 28,023 lb of recorded Holsteins in 2020, but the two are different measures: NASS counts actual milk per cow across all breeds and herds, including dry cows, while the CDCB figures are standardized 305-day yields for recorded cows (USDA NASS Milk Production, December 2025 release). The AHDB makes the same warning for UK averages: they divide total recorded milk by herd size, so use them with caution (AHDB, UK milk yield).

In Canada, Agriculture and Agri-Food Canada compiles milk-recording data. The Canadian numbers are 305-day yields in kilograms, on a different basis from the US mature-age standardized figures. For the same breed they are lower: Canada’s Holstein figure of 11,147 kg is about 24,600 lb, against 28,023 lb in the CDCB table.

Australia is a pasture-based market where the Holstein is not the only choice. The Dairy Australia 2022 Animal Husbandry and Genetics Survey, as reported by Farm Online, found that 67% of farms had Holstein and/or Friesian cows, 15% had crossbreds, 9% had Jerseys and 4% had red breeds (Farm Online, November 2025). That counts farms, not cows.

Heat, small breeds and crossbreds

Hot, humid weather cuts milk. A Costa Rican study of 6.5 million daily records from 418 herds, 1990 to 2015, found that when THI rose between 72 and 88, daily milk fell for Holsteins, Holstein-Jersey crosses and Jerseys, and fell least for the Jerseys. It put the extra loss per lactation in the hotter northern region, compared with the central region, at $680 per Holstein, $587 per cross and $477 per Jersey (the abstract gives dollars and does not name the currency) (Agronomía Mesoamericana, 2019). It is a tropical study, and it does not show the same size of loss in a US or European barn with fans and sprinklers. It does support one rule: in a hot region, cooling and a heat-tolerant type matter as much as the breed name.

Small breeds such as the Jersey give less milk per cow, so they have to earn their keep through components or lower costs, which the calculator below lets you test.

Hairy and cold-hardy breeds

Some readers ask about hairy cow breeds. CDCB, ICAR and the Canadian tables used here do not report yields for them, so we do not rank them. If you keep a local or cold-hardy breed, compare it with your own milk records and not with the table above.

Crossbreeding

At the University of Minnesota, Montbéliarde-sired crossbred first-calf cows (57 cows) were compared with Holsteins (40 cows). The crossbreds did not differ from the Holsteins in feed intake or fat plus protein for 305 days, and they had fewer days open, 122 against 150 (University of Minnesota study in Experts@Minnesota). It is one trial with first-lactation cows in one confinement herd. It does not show that crossbreds always match Holsteins for milk.

How to choose a dairy cow breed

Use these steps and let your own numbers decide.

1. Find your milk pay basis. Check whether you are paid per litre, per pound of fat and protein, or with a cheese premium.
2. Match the cow to the ration. A 28,000 lb cow needs a high-energy ration all year. A pasture herd with a lower-energy ration may do better with a smaller, hardier cow.
3. Count heat days. If THI is above 72 on many days, price cooling first.
4. Check fertility and replacement costs. Days open and cull rates change income as much as milk does.
5. Run the numbers. Use the calculator on your own records.

Feed, pasture and cow comfort

Satellite maps for pasture

Breed sets the ceiling, and feed and comfort decide how close a herd gets to it. Pasture and forage quality drive intake on grazing farms, and satellite vegetation maps can show which paddocks are growing well. They show plant cover, not cow health or milk, so use them next to your own records. Farmonaut Satellite + AI Farm Monitoring System offers this kind of field view on web, Android and iOS.

FAQ

Which cow gives the most milk?

The Holstein. CDCB reports 28,023 lb of standardized 305-day milk per recorded cow in 2020, ahead of the Brown Swiss at 23,245 lb and the Jersey at 20,931 lb.

Which cow breed has the richest milk?

The Jersey, with 4.82% fat and 3.68% protein in the 2020 US tables (CDCB). In Canada’s recorded herds it gave 5.14% fat and 3.89% protein.

What is the best cow for milk on a small farm?

There is no single answer. The Jersey and Guernsey give less milk but more fat and protein. Compare income over feed with the calculator, using your own milk price and ration cost.

Do Holsteins suffer more in hot weather than Jerseys?

In the Costa Rican study of 418 herds, yes: daily milk fell by more per THI step for Holsteins than for Jerseys. Cooling can cut the loss, and the result may differ in your climate.

Is crossbreeding a good choice?

It can help fertility. In one University of Minnesota trial, crossbreds matched Holsteins for fat plus protein and had fewer days open. It is one trial, so test it in your own herd and ask your breeding adviser.

How we checked the numbers

We used the CDCB national standardized lactation tables for calving year 2020, the Agriculture and Agri-Food Canada milk-recording table, the USDA ERS and NASS pages, and two peer-reviewed or university sources for heat and crossbreeding. The fat plus protein column adds figures from the CDCB tables. The CDCB tables show the latest year on that page as 2020, and use the older 305-day mature-equivalent method. CDCB replaced that standard with 305-AA (a 36-month age basis) in 2024, so newer CDCB figures will not match these. Breeding, diet and management advice here is general; get advice from your herd vet or dairy nutritionist before you change a ration or a breeding plan.
