Pig milk 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. [1]
Pig milk contains 8.5% fat compared to 3.5% in cow's milk. [2] It has similar colostrum composition in terms of protein, fat, and lactose, when compared to cow's milk. [3] Pigs with high-protein diets produce more milk compared to those on low-protein diets. [4] It is also described as more gamy than goat's milk and seems more watery than cow's milk.
Pig milk is not considered suitable for commercial production for a number of reasons. Pigs are considered difficult to milk. The sow herself is reluctant to be milked, may be uncooperative or become spooked by human presence, and lactating pigs may be quite aggressive. [5] [6] [7] Sows have 8 to 16 small nipples, each giving little milk for a short duration. A pig's milking time can be around fifteen seconds compared to ten minutes for a cow. A sow may produce only 13 pounds of milk per day compared to a cow's production of 65 pounds. (Production has been estimated using a system of weighing piglets prior to and after suckling.) [8] In addition, no existing milking machine is designed to attach to around a dozen teats and extract milk for 15 seconds. Finally, pigs, unlike cows, cannot become pregnant while lactating, which makes a pig-milk operation even less viable. [2]
Compared to more conventional animals such as dairy cattle or goats, a main issue is their omnivorous diet. [9] Also, the flavor of pig milk has been described as "gamy", more so than goat's milk. [10] The milk is also considered more watery than cow's milk. [10] [7]
Cheese produced from pig milk has been described as having a concentrated and intensified flavor of pig milk. [5] Chef Edward Lee prepared a ricotta cheese from pig milk, which he described as "delicious". [6]
A Dutch farmer produced one of the first experimental pig milk cheeses. As many as ten people worked to milk the sows for dozens of hours. Several of the attempts to produce cheese failed. They finally managed to make a few kilograms. It was reported that it tasted "chalky and a little bit salty" [11] and compared to other cheeses "saltier and creamier, yet grainier". [12] The cheese was sold to an anonymous buyer at a children's charity for $2,300 per kilogram. The price fetched was higher than the most expensive variety known as pule cheese, which is made from the milk of the Serbian Balkan donkey.
Susanna Montgomerie, Countess of Eglinton used to wash her face with pig milk and then drink it. She recommended this treatment to others, as she believed it would help retain one's figure and complexion. [13]
Milk is a white liquid food produced by the mammary glands of mammals. It is the primary source of nutrition for young mammals before they are able to digest solid food. Immune factors and immune-modulating components in milk contribute to milk immunity. Early-lactation milk, which is called colostrum, contains antibodies that strengthen the immune system and thus reduce the risk of many diseases. Milk contains many nutrients, including calcium and protein, but also lactose and saturated fat.
A dairy is a place where milk is stored and where butter, cheese and other dairy products are made, or a place where those products are sold. It may be a room, a building or a larger establishment. In the United States, the word may also describe a dairy farm or the part of a mixed farm dedicated to milk for human consumption, whether from cows, buffaloes, goats, yaks, sheep, horses or camels.
Dairy farming is a class of agriculture for the long-term production of milk, which is processed for the eventual sale of a dairy product. Dairy farming has a history that goes back to the early Neolithic era, around the seventh millennium BC, in many regions of Europe and Africa. Before the 20th century, milking was done by hand on small farms. Beginning in the early 20th century, milking was done in large scale dairy farms with innovations including rotary parlors, the milking pipeline, and automatic milking systems that were commercially developed in the early 1990s.
Bovine somatotropin or bovine somatotrophin, or bovine growth hormone (BGH), is a peptide hormone produced by cows' pituitary glands. Like other hormones, it is produced in small quantities and is used in regulating metabolic processes. Scientists created a bacterium that produces the hormone somatotropin which is produced by the cow's body after giving birth and increases milk production by around 10 percent.
Ricotta is an Italian whey cheese made from sheep, cow, goat, or Italian water buffalo milk whey left over from the production of other cheeses. Like other whey cheeses, it is made by coagulating the proteins that remain after the casein has been used to make cheese, notably albumin and globulin.
Dairy cattle are cattle bred with the ability to produce large quantities of milk, from which dairy products are made. Dairy cattle generally are of the species Bos taurus.
Goat milk is the milk of domestic goats. Goats produce about 2% of the world's total annual milk supply. Some goats are bred specifically for milk. Goat milk naturally has small, well-emulsified fat globules, which means the cream will stay in suspension for a longer period of time than cow's milk; therefore, it does not need to be homogenized. Eventually, the cream will rise to the top over a period of a few days. If the milk is to be used to make cheese, homogenization is not recommended, as this changes the structure of the milk, affecting the culture's ability to coagulate the milk as well as the final quality and yield of cheese.
In animal husbandry, feed conversion ratio (FCR) or feed conversion rate is a ratio or rate measuring of the efficiency with which the bodies of livestock convert animal feed into the desired output. For dairy cows, for example, the output is milk, whereas in animals raised for meat the output is the flesh, that is, the body mass gained by the animal, represented either in the final mass of the animal or the mass of the dressed output. FCR is the mass of the input divided by the output. In some sectors, feed efficiency, which is the output divided by the input, is used. These concepts are also closely related to efficiency of conversion of ingested foods (ECI).
Camel milk is milk from female camels. It 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, especially in parts of the Middle East, North Africa and the Horn of Africa. 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.
Cheese is a type of dairy product produced in a range of flavors, textures, and forms by coagulation of the milk protein casein. It comprises proteins and fat from milk. During production, milk is usually acidified and either the enzymes of rennet or bacterial enzymes with similar activity are added to cause the casein to coagulate. The solid curds are then separated from the liquid whey and pressed into finished cheese. Some cheeses have aromatic molds on the rind, the outer layer, or throughout.
Moose milk, also known as elk milk, refers to milk produced by moose. Though it is most commonly consumed by moose calves, its production has also been commercialised in Russia and Sweden.
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), Pecorino romano (Italy), Roquefort (France) and Manchego (Spain).
The Alpine is a medium to large sized breed of domestic goat known for its very good milking ability. They have no set colours or markings. They have horns, a straight profile and erect ears.
The British Milksheep is a robust, dual-purpose sheep commonly known for its milking characteristics.
Bovine mastitis is the persistent, inflammatory reaction of the udder tissue due to physical trauma or microorganisms infections. Mastitis, a potentially fatal mammary gland infection, is the most common disease in dairy cattle in the United States and worldwide. It is also the most costly disease to the dairy industry. Milk from cows suffering from mastitis has an increased somatic cell count. Prevention and control of mastitis requires consistency in sanitizing the cow barn facilities, proper milking procedure and segregation of infected animals. Treatment of the disease is carried out by penicillin injection in combination with sulphar drug.
Porcine epidemic diarrhea is a condition caused by the porcine epidemic diarrhea virus that leads to severe gastrointestinal disease in pigs.
Chhena or chhana is a kind of acid-set cheese originating in the Indian subcontinent that is made from water buffalo or cow milk by adding food acids such as lemon juice and calcium lactate instead of rennet and straining out the whey.
Goat farming involves the raising and breeding of domestic goats as a branch of animal husbandry. People farm goats principally for their meat, milk, fibre and skins.
A dry cow refers to a dairy cow that is in a stage of their lactation cycle where milk production ceases prior to calving. This part of their lactation cycle is referred to as the cows dry period and typically last between 40 and 65 days. Dry cows are typically divided into two groups: far-off and close-up. Once the cow has entered this stage, producers will seal the cows teat while following a veterinarian recommended, dry cow therapy for their herd. This dry period is a critical part of their lactation cycle and is important for the cows health, the newborn calf and future milk production, as it allows the cow time to rest, eat and prepare for birth. During this time, the cow will produce colostrum for the newly born calf.
Dairy plays a significant part in numerous aspects of Indian society, including cuisine, religion, culture, and the economy.
