Dairy products or milk products are a type of food produced from or containing the milk of mammals, most commonly cattle, water buffaloes, goats, sheep, and camels. Dairy products include food items such as yogurt, cheese and butter. A facility that produces dairy products is known as a dairy, or dairy factory. Dairy products are consumed worldwide, with the exception of most of East and Southeast Asia and parts of central Africa.
Milk is a nutrient-rich liquid food produced by the mammary glands of mammals. It is the primary source of nutrition for young mammals, including breastfed human infants before they are able to digest solid food. Early-lactation milk is called colostrum, which contains antibodies that strengthen the immune system and thus reduces the risk of many diseases. It holds many other nutrients, including protein and lactose. Interspecies consumption of milk is not uncommon - many human beings consume the milk of other mammals.
Rennet is a complex set of enzymes produced in the stomachs of ruminant mammals. Chymosin, its key component, is a protease enzyme that curdles the casein in milk. In addition to chymosin, rennet contains other enzymes, such as pepsin and a lipase.
The donkey or ass is a domestic animal in the horse family. It derives from the African wild ass, Equus africanus, and has been used as a working animal for at least 5000 years. There are more than 40 million donkeys in the world, mostly in underdeveloped countries, where they are used principally as draught or pack animals. Working donkeys are often associated with those living at or below subsistence levels. Small numbers of donkeys are kept for breeding or as pets in developed countries.
A dairy is a business enterprise established for the harvesting or processing of animal milk – mostly from cows or buffaloes, but also from goats, sheep, horses, or camels – for human consumption. A dairy is typically located on a dedicated dairy farm or in a section of a multi-purpose farm that is concerned with the harvesting of milk.
Whey is the liquid remaining after milk has been curdled and strained. It is a byproduct of the manufacture of cheese or casein and has several commercial uses. Sweet whey is a byproduct resulting from the manufacture of rennet types of hard cheese, like cheddar or Swiss cheese. Acid whey is a byproduct brought out during the making of acid types of dairy products, such as cottage cheese or strained yogurt.
Kumis Mongolian: айраг, ääryg) is a fermented dairy product traditionally made from mare's milk or donkey milk. The drink remains important to the peoples of the Central Asian steppes, of Turkic and Mongol origin: Kazakhs, Bashkirs, Kalmyks, Kyrgyz, Mongols, and Sakha. Kumis was historically consumed by the Khitan, Jurchen, Hungarians and Han Chinese of North China as well.
Colostrum is the first form of milk produced by the mammary glands of mammals immediately following delivery of the newborn. Most species will begin to generate colostrum just prior to giving birth. Colostrum has an especially high amount of bioactive compounds compared to mature milk to give the newborn the best possible start to life. Specifically, colostrum contains antibodies to protect the newborn against disease and infection, and immune and growth factors and other bioactives that help to activate a newborn’s immune system, jumpstart gut function, and seed a healthy gut microbiome in the first few days of life. The bioactives found in colostrum are essential for a newborn’s health, growth and vitality.
Bovine somatotropin or bovine somatotrophin, or bovine growth hormone (BGH), is a peptide hormone produced by cows' pituitary glands.
Raw milk or unpasteurized milk is milk that has not been pasteurized, a process of heating liquid foods to kill pathogens for safe consumption and extending the shelf life. Proponents of raw milk have stated that there are benefits to its consumption, including better flavor, better nutrition, and the building of a healthy immune system. However, the medical community has warned of the dangers, which include a risk of infection, and has not found any clear benefit. The combination of the lack of a clear benefit along with substantial evidence, dating back hundreds of years, to the potential infection risk has led to countries around the world either outright prohibiting its sale or requiring warning labels on the product.
A foal is an equine up to one year old; this term is used mainly for horses, but can be used for donkeys. More specific terms are colt for a male foal and filly for a female foal, and are used until the horse is three or four. When the foal is nursing from its dam (mother), it may also be called a "suckling". After it has been weaned from its dam, it may be called a "weanling". When a mare is pregnant, she is said to be "in foal". When the mare gives birth, she is "foaling", and the impending birth is usually stated as "to foal". A newborn horse is "foaled".
Whey protein is a mixture of proteins isolated from whey, the liquid material created as a by-product of cheese production. The proteins consist of α-lactalbumin, β-lactoglobulin, serum albumin and immunoglobulins. Whey protein is commonly marketed as a protein supplement, and various health claims have been attributed to it. A review published in 2010 in the European Food Safety Authority Journal concluded that the provided literature did not adequately support the proposed claims. For muscle growth, whey protein has been shown to be slightly better compared to other types of protein, such as casein or soy.
A mare is an adult female horse or other equine. In most cases, a mare is a female horse over the age of three, and a filly is a female horse three and younger. In Thoroughbred horse racing, a mare is defined as a female horse more than four years old. The word can also be used for other female equine animals, particularly mules and zebras, but a female donkey is usually called a "jenny". A broodmare is a mare used for breeding. A horse's female parent is known as its dam.
Goat milk is the milk of domestic goats.
Camel milk has supported nomad and pastoral cultures since the domestication of camels millennia ago. Herders may for periods survive solely on the milk when taking the camels on long distances to graze in desert and arid environments. The camel dairy farming industry has grown in Australia and the United States, as an environmentally-friendly alternative to cow dairy farming using a species well-adapted to arid regions.
Sheep's milk is the milk of domestic sheep. It is commonly used to make cultured dairy products such as cheese. Some of the most popular sheep cheeses include feta (Greece), ricotta (Italy), and Roquefort (France).
Donkey milk is the milk from the domesticated donkey (Equus asinus). It has been used since antiquity for cosmetic purposes as well as infant nutrition.
Pig milk is milk from pigs, and is typically consumed by piglets. It is similar in composition to cow's milk, though higher in fat and more watery. Pig milk is seldom obtained for human uses and is not considered to be a viable agricultural product. Several attempts have been made to produce pig milk cheese, some of which have been successful.
The Ohio Department of Agriculture (ODA) is the administrative department of the Ohio state government responsible for ensuring the safety of the food supply, to maintain the health of animals and plant life, to create economic opportunities for farmers, food processors and agribusinesses, and to inspect amusement park rides in the state of Ohio.
The dairy industry in the United States includes the farms, cooperatives, and companies that produce milk and cheese and related products, such as milking machines, and distribute them to the consumer. By 1925, the United States had 1.5-2 million dairy cows, each producing an average of 4200 lb of milk per year. By 2007, there were 9.1 million dairy cows but their average milk production was over 20,000 pounds per year, with eight pounds per gallon.
