Organic Milk

Milk and milk products that are labeled “USDA organic.” This is products deriving from milk that comes from farms that meet USDA’s National Organic Program standards. Organic milk is one of many options in the dairy case – and all pasteurized milk is safe, delicious and nutritious, no matter which variety people choose.

Milking Parlor

A specialized area on the dairy farm where cows are milked two or three times a day. Equipment delivers the milk directly from the cows to a refrigerated holding tank to preserve freshness and safety. The milk is then quickly transported to the dairy plant. Parlors come in many types, including flat barn, herringbone, parallel, swing, walk-through and rotary.

Livestock Veterinarian

Animal doctors who have earned a degree in veterinary medicine. Sometimes called “large animal veterinarians,” many specialize in the treatment of dairy cows and work directly with dairy farmers to ensure healthy herds.

Milking Machines

Machinery used on the farm to extract milk from cows. Electronic milking machines use a pulsating vacuum that simulates the effect of a suckling calf. The machines do not cause any harm or discomfort to the cows and they keep the milk safe from external contamination.

Methane Digester

Technology that converts cow manure into methane gas that is burned as fuel to generate electricity.

Nutrient Management Plan

A planning resource that defines the nutrient needs of crops and the amount, sources, placement, and timing of fertilizer applications to maximize nutrient uptake of crops and improve yields. Nutrient management plans help protect the environment and crop production.


A simple, effective method to kill harmful pathogens through heat treatment without affecting the taste or nutritional value of milk. Pasteurization is recognized around the world as an essential tool for protecting public health since it was first introduced in 1864. The process was named after French scientist Louis Pasteur.

Replacement Heifers

Female dairy animals that are raised with the intent of eventually replacing the cows currently in the milking herd.

rBGH or rBST

A synthetic version of bovine somatotropin that some farmers opt to use to increase milk production. rbST is a naturally-occurring protein hormone in cows. A trace amount of this hormone is present in all milk, including organic products, and is digested when humans eat it, just like other proteins. rbST has been in use for more than 20 years, and its safety has been affirmed and reaffirmed by government agencies in the United States and around the world.


The largest of the four compartments in a cows’ stomach. The rumen allows cows to regurgitate forage and re-chew their cud for further digestion.


Any hooved animal, such as a dairy cow, that digests its food by first eating the raw material and then regurgitating a semi-digested form known as cud. These animals then eat their cud, a process called ruminating. Other ruminants include goats, sheep, camels, llamas, giraffes, bison, buffalo, and deer.


Any substance created to prevent, destroy or repel insects, plant pathogens, weeds, nematodes, and microbes that destroy property, spread disease or are a nuisance.

Raw Milk

Milk that has not been pasteurized before consumption. The dairy industry has long endorsed pasteurization in killing potentially harmful microorganisms as a major public health protection. Pasteurization does not affect the nutritional value of milk in any meaningful way.

Processing Plant

A facility that pasteurizes, homogenizes and packages/bottles milk that comes directly from dairy farms. Once milk leaves the plant, it is available to the public through a variety of channels, including grocery stores, schools and restaurants.


Land at a dairy farm that is lush with grasses or legumes and is used for grazing dairy cows.


A bag-shaped part on the underside of a female cow in which milk is formed and stored.


The cow’s udder contains four teats that function as the exit for milk.

Ear Tag

A device similar to an earring that dairy farmers place in the ears of their animals to identify each member of the herd. Ear tags contain a number that is given to that particular cow and allows the dairy farmer to maintain accurate health and milk production records.


The partially digested food that is regurgitated from the first compartment of the cow’s stomach into the mouth to be chewed again. A cow may spend seven hours a day eating food and an additional 10 hours a day chewing her cud.


A young female dairy animal before she has matured. A young male is called a bull calf.


The dominant protein (80 percent) in cow’s milk. Casein is vital to cheesemaking and has a variety of uses in manufacturing.


Butter is produced by churning the fat from milk or cream until it solidifies. It may then be salted.


Also known as milkfat, the fatty portion of milk. Milk and cream are often sold according to the amount of butterfat they contain. In the United States, there are federal standards for butterfat content of dairy products.
