Sharing is caring!

Have you ever watched cows grazing peacefully in a pasture and wondered how much milk they actually produce? Maybe you’re even dreaming of adding a beautiful, brown-eyed Jersey to your homestead or hobby farm. If so, you’re in the right place! Let’s dive into The Truth About Daily Milk Production for Jersey Cows.

What is a Jersey Cow?

The Jersey breed is a brown bovine with large brown eyes. They have iconic long eyelashes, and usually darker brown tips on the ears and tail. While Jerseys are not as large as Holsteins or Brown Swiss cows, don’t let their moderate size fool you—they are renowned for being incredibly efficient and productive milk producers. Jerseys are the second most popular breed of dairy cattle worldwide, behind the Holstein. Jerseys are cherished by homesteaders and small farms for their docile temperament and rich milk.

Why Raise a Jersey?

Homesteaders and Commercial Dairies both love Jerseys because of the butterfat content the cows tend to provide. In simple terms, the butterfat content means that dairies receive a better payout. The dairy industry milk bonuses are often priced on milk solids (like butterfat content and protein). For the homesteader, a higher butterfat content means more ice cream, butter, sour cream, and (certain) cheese potential. Butterfat is usually a key differentiator for Jerseys compared to breeds like Holsteins, which typically produce a higher volume of milk but tend to have lower butterfat levels.

Beyond milk quality, Jerseys require less barn space, less acreage per cow, and fewer feed inputs due to their smaller size. In fact, Jerseys can produce more milk per pound of feed compared to larger cows. Jerseys are efficient grazers. Depending on their genetics, Jerseys can thrive on a grass-based diet. Some Jerseys are great in grass-fed settings and never require grain. This can allow farmers and homesteaders to receive a premium price for the trending “Grass Fed” labeled product.

Our Experience with Jersey Cows

What experience do we have with dairy cows? When we were teenagers, both my husband and I worked on dairy farms. These farms predominantly milked Holstein cows, but they also added a few Jersey cows to increase the butterfat content in the bulk tank.

Outside of the commercial setting, we’ve personally owned multiple dairy cattle. They ranged from Ayrshire, Guernsey, and Red Holsteins to Brown Swiss, Normande, and Jerseys. 

While the colorful barnyard brought smiles to our faces, we did learn that we gravitated to the taste and creaminess of that delicious Jersey milk. The Ayrshire milk was great for baking, but we didn’t actually like the taste of it. The Guernsey milk was more golden in color, but wasn’t as creamy. Holstein milk did not have much of a cream line. The truth is, Jersey milk just tasted a little better to us. Milk from the Jersey cows tasted a bit sweeter (and if you know me, you know I have a sweet tooth), had a remarkable cream line, and poured a delectable glass of milk.

From Freshening to Peak: The Jersey Lactation Curve

So, what’s the truth about daily milk production for Jersey cows? How much milk do Jersey cows actually produce?

Let’s start at the very beginning of a cow’s lactation cycle. When a cow freshens (gives birth), she produces colostrum, or what my family refers to as “liquid gold”. This colostrum is the first milk that the cows (or any mammals, actually) make. Why is colostrum so important? It gives the calf a healthy start in life by creating passive immunity as the calf consumes the colostrum. Colostrum itself is loaded with rich nutrients and antibodies, specifically Immunoglobulin G (IgG). 

Midwest Dairy reports that Jersey cows can produce 7 gallons per day. 

To get a better understanding of milk production, it’s important to know that a cow’s production changes over time. This is called the Lactation Curve.

After the initial colostrum milking, the cow’s fluid milk production will gradually increase. They’ll reach their peak lactation at 4-8 weeks after freshening, after which production will start tapering off.

Measuring Jersey Productivity: Lactation Averages and Dry-Off

The US Jersey Journal has announced that  registered Jerseys are now averaging a milk yield of 20,710 pounds of milk per lactation. 

A gallon of milk weighs 8.6 pounds, which is 2,408 gallons of milk per a cow per lactation. If we divide that amount by the average 305 lactation period, the amount comes to more than 7 gallons a day in average. This calculation aligns with, and even slightly exceeds, the 7 gallons per day reported by Midwest Dairy, reinforcing their excellent daily output.

Understanding this full production cycle also means knowing about the dry-off period, which is a crucial phase. 

Many dairy farmers operate on a 305-day lactation cycle. That simply means that the cows are typically milked for 305 days. As it gets closer to the cow freshening, or calving, the farmers dry off the cows. The dryoff period is the time that the cows are not milked and are given a period of rest before their next calf is born. Personally, I like to allow my cows a generous 60-90 day dry-off period to ensure they’re well-rested and ready for their next cycle of producing that delicious Jersey milk.

Fluctuations in Milk Production

While it’s true that registered Jerseys in the United States average around 7 gallons of milk daily during their lactation, it may not always be a realistic expectation for hobby farms and homesteaders. We’ve personally observed this; cows we’ve purchased from commercial dairies often show a change in their production once they arrive at our home.

Let’s explore some of the major factors that influence the dairy animals’ output:

One of the significant reasons commercial dairies achieve such high volumes of raw milk (whether intended for direct human consumption or pasteurization) is their comprehensive feeding programs. They typically grain-feed their cows strategically and consistently provide high-quality roughages such as silage and haylage to maximize milk production.

Genetics also play a huge role. Commercial dairies use selective breeding for high milk production traits, as having high-producing animals is essential for their business viability.

Additionally, a first-time heifer will not produce as much milk the first time around compared to her second lactation and the following lactations.

Furthermore, these dairies regularly test for Somatic Cell Count (SCC) and sample the components of their bulk tank. SCC levels are a strong indicator of  animal health; high numbers can signal health problems such as a mastitis issue, sickness in the Jersey herd, or simply a cow being in milk for longer periods. Farmers aim to keep those SCC numbers low not only for herd health but also because low SCC levels can earn them a bonus on their monthly milk check.

Lastly, the quality of forage greatly impacts production. Fresh, lush grass and high-quality forage can significantly boost milk production. However, if cows don’t have consistent access to healthy pastures, their production levels may not reach their maximum genetic potential without supplementing with substantial amounts of grain. It’s important to note that cows relying solely on a grass-based diet generally do not produce as much milk as their grain-fed counterparts.

How Homesteaders Can Maximize Their Cow’s Potential

Often times, homesteads simply don’t have the resources compared to a large dairy operation. The truth about daily milk production for Jersey cows is that it takes work. 

Make sure your cow always has access to clean, fresh water. Monitor her body condition. A fat heifer or cow can cause metabolic issues, Fatty Liver Disease, and make it extremely difficult to get bred. However, an under-conditioned Jersey cow can also be a cause for health issues.

Provide the family milk cow with quality feed and hay. This will help her be healthier and add more milk to your pail. Your cow will need trace minerals, salt, and the occasional dewormer. 

A clean, safe environment will help your cow stay healthier and reduce stress, which improves production. Consistency is key with dairy animals. Regular and reliable milking times and techniques can increase the dairy yield and minimize issues with udder health. Cows like consistency. A happy cow will give more milk.

Work closely with your veterinarian or dairy mentor to do everything possible to keep your cow healthy.

Is a Dairy Cow Right for Your Homestead?

Honestly, owning a cow is expensive. The daily feed cost, fencing expenses, Veterinary bills, bedding, and hay all add up, let alone the time investment. A Dexter cow, miniature Jersey, or a heritage breed of cow (Milking Shorthorn, Devon, etc.) is not going to produce as much as a full sized Jersey, or large framed dairy cow. 

If you’re in the cow market, be sure to do your research before making a purchase. This blog post and free printable will help with that dairy purchase decision.

The Truth Is

When it comes to the fresh milk output, the truth about daily milk production for Jersey cows is that different factors contribute to the average production amounts.

Each cow is different. Each farm is different. A Jersey cow can produce over 7 gallons a day on average. If you’re getting started with a family cow, just remember that the amount of milk at your farm will be different compared to the large Jersey farmers’ operations. It’s more important to take proper care of your dairy cow than it is to try to break a milking output record. Enjoy those homemade dairy products (like yogurt, Quark, chocolate milk, Ice Cream, and firm cheeses) and always do your best to take care of your animal.
