Did You Know? Dairy Cows Have Four Stomach Compartments !
A cow's stomach is made up of four compartments: the rumen, reticulum, omasum, and abomasum. Together, they help digest feed by breaking down plant fibers and absorbing nutrients that are used to produce milk.

How Do Dairy Cows Stay Cool?
Cows don't sweat like people do, so they stay cool by drinking plenty of water, relaxing in shaded areas, and enjoying fans and sprinkler systems on warm days. Keeping cows comfortably cool helps them stay healthy and continue to produce high-quality milk.

How Do You Milk a Cow?
For thousands of years, cows were milked by hand. Today, most dairy farms use one of three modern milking systems that make the process more efficient while keeping cows comfortable.
Traditional Milking Parlor: Cows are milked in individual stalls while a milker gently attaches the milking equipment, called a claw, to the cow's udder. The machine collects milk in about 3–5 minutes before the cow returns to the barn.
Rotary (Carousel) Parlor: Cows step onto a slow-moving rotating platform where the milking equipment is attached. As the carousel turns, the cows are milked, and by the time they reach the end of the rotation, they simply step off and head back to the barn. The entire process takes about 7–10 minutes.
Robotic Milking System: In this system, cows choose when they want to be milked. A robotic milking unit identifies each cow, cleans the udder, attaches the milking equipment, and monitors the entire milking process before the cow returns to eat, drink, or rest. -
How Much Milk Does a Dairy Cow Produce?
The amount of milk a dairy cow produces depends on her breed, age, nutrition, health, and stage of lactation.
On average, a dairy cow produces 6–7 gallons of milk each day—about 96 glasses of milk. Dairy farmers work hard to ensure cows receive proper nutrition, fresh water, and excellent care to support their health and milk production. -
How Do Cows Make Milk?
A dairy cow's digestive system is specially designed to turn plants into nutritious milk. As a ruminant, she has four stomach compartments that work together to digest grasses, hay, corn, grains, and other feeds. During digestion, nutrients from the feed and water are absorbed into the bloodstream and transported to the udder, where specialized cells use them to produce milk.
On average, a dairy cow eats about 90–100 pounds of feed and drinks 25–50 gallons of water each day. With proper nutrition and care, one dairy cow can produce approximately 200,000 glasses of milk during her lifetime. -
What's in Milk?
Fresh milk naturally contains cream and skim (nonfat) milk. Before milk is homogenized, the lighter cream naturally rises to the top. That cream is used to make butter, whipped cream, and many other dairy products.
Milk is also one of the most nutrient-rich beverages available, providing 13 essential nutrients, including calcium, high-quality protein, potassium, phosphorus, and vitamins A, D, and B12. Together, these nutrients help support strong bones, healthy muscles, and overall health at every stage of life. -
What Foods Come from Milk?
Milk is the starting point for many of your favorite foods, including cheese, yogurt, butter, ice cream, cottage cheese, sour cream, whipped cream, and more! Because these foods are made from milk, they naturally provide many of the same essential nutrients, making them both nutritious and delicious. Whether enjoyed as a snack, ingredient, or dessert, dairy foods can be part of a healthy, balanced diet.
