For milk derived from plants, see Plant milk. For other uses of the word, see Milk (disambiguation). Milk is a pale liquid produced by the mammary glands of mammals. It is the primary source of nutrition for infant mammals (including humans who breastfeed) before they are able to digest other types of food. Early- lactation milk contains colostrum, which carries the mother's antibodies to its young and can reduce the risk of many diseases. It contains many other nutrients. Dairy farms produced about 7. Over 7. 50 million people live in dairy farming households. The early milk from mammals is called colostrum. Colostrum contains antibodies that provide protection to the newborn baby as well as nutrients and growth factors. This introduces the risk of the child developing electrolyte imbalances, metabolic acidosis, megaloblastic anemia, and a host of allergic reactions. Initially, the ability to digest milk was limited to children as adults did not produce lactase, an enzyme necessary for digesting the lactose in milk. Milk was therefore converted to curd, cheese and other products to reduce the levels of lactose. Thousands of years ago, a chance mutation spread in human populations in Europe that enabled the production of lactase in adulthood. This allowed milk to be used as a new source of nutrition which could sustain populations when other food sources failed. Modern industrial processes use milk to produce casein, whey protein, lactose, condensed milk, powdered milk, and many other food- additives and industrial products. Whole milk, butter and cream have high levels of saturated fat. The enzyme needed to digest lactose, lactase, reaches its highest levels in the small intestine after birth and then begins a slow decline unless milk is consumed regularly. The largest producer and consumer of cattle and buffalo milk in the world is India. In addition, a substance secreted by pigeons to feed their young is called . Milk can be synthesized in a laboratory, from water, fatty acids and proteins. Much of the argument is based on monotremes (egg- laying mammals). This development occurred independently in several places around the world from as early as 9. Pastoral and pastoral nomadic economies, which rely predominantly or exclusively on domestic animals and their products rather than crop farming, were developed as European farmers moved into the Pontic- Caspian steppe in the fourth millennium BC, and subsequently spread across much of the Eurasian steppe. Milk consumption became common in these regions comparatively recently, as a consequence of European colonialism and political domination over much of the world in the last 5. In the Middle Ages, milk was called the . Individual railway firms began transporting milk from rural areas to London from the 1. Possibly the first such instance was in 1. St Thomas's Hospital in Southwark contracted with milk suppliers outside London to provide milk by rail. By 1. 90. 0, the company was transporting over 2. Over the last three decades of the 1. Legislation in 1. The proportion of rural imports by rail as a percentage of total milk consumption in London grew from under 5% in the 1. By that point, the supply system for milk was the most highly organized and integrated of any food product. The first company to do so may have been the New York Dairy Company in 1. The Express Dairy Company in England began glass bottle production in 1. In 1. 88. 4, Hervey Thatcher, an American inventor from New York, invented a glass milk bottle, called 'Thatcher's Common Sense Milk Jar', which was sealed with a waxed paper disk. Pasteurization was originally used as a way of preventing wine and beer from souring. Russia and China became self- sufficient and stopped importing milk. Canada has tried to restrict milk production by forcing new farmers/increased capacity to . Importing milk is prohibited. The European Union theoretically stopped subsidizing dairy farming in 2. Direct subsidies were replaced by . The United States has a voluntary insurance program that pays farmers depending upon the price of milk and the cost of feed. In 2. 01. 1, FAO estimates 8. Commercial dairy farming using automated milking equipment produces the vast majority of milk in developed countries. Dairy cattle such as the Holstein have been bred selectively for increased milk production. About 9. 0% of the dairy cows in the United States and 8. Great Britain are Holsteins. These animals include buffalo, goat, sheep, camel, donkey, horse, reindeer and yak. The first four respectively produced about 1. In turn, the opportunities presented by these growing markets have attracted investments by multinational dairy firms. Nevertheless, in many countries production remains on a small scale and presents significant opportunities for diversification of income sources by small farms. This survey over 2. ICAR (International Committee for Animal Recording. The survey found that the average herd size in these developed countries increased from 7. A dairy farm had an average of 1. Norway, and 3. 37 in New Zealand. Annual milk production in the same period increased from 7,7. The lowest average production was in New Zealand at 3,9. The milk yield per cow depended on production systems, nutrition of the cows, and only to a minor extent different genetic potential of the animals. What the cow ate made the most impact on the production obtained. New Zealand cows with the lowest yield per year grazed all year, in contrast to Israel with the highest yield where the cows ate in barns with an energy- rich mixed diet. The milk yield per cow in the United States, the world's largest cow milk producer, was 9,9. In contrast, the milk yields per cow in India and China . Particularly notable was the rapid increase of consumption of milk in China and the rise of the price of milk in the United States above the government subsidized price. The principal requirements are energy (lipids, lactose, and protein), biosynthesis of non- essential amino acids supplied by proteins (essential amino acids and amino groups), essential fatty acids, vitamins and inorganic elements, and water. Milk from other bovines and non- bovine mammals varies in composition, but has a similar p. H. Lipids. Initially milk fat is secreted in the form of a fat globule surrounded by a membrane. These act as emulsifiers which keep the individual globules from coalescing and protect the contents of these globules from various enzymes in the fluid portion of the milk. Unlike protein and carbohydrates, fat composition in milk varies widely in the composition due to genetic, lactational, and nutritional factor difference between different species. Diameter may also vary between animals within a species and at different times within a milking of a single animal. In unhomogenized cow's milk, the fat globules have an average diameter of two to four micrometers and with homogenization, average around 0. Total proteins in milk represent 3. Caseins. The largest structures in the fluid portion of the milk are . Each casein micelle is roughly spherical and about a tenth of a micrometer across. There are four different types of casein proteins: . Collectively, they make up around 7. Most of the casein proteins are bound into the micelles. There are several competing theories regarding the precise structure of the micelles, but they share one important feature: the outermost layer consists of strands of one type of protein, k- casein, reaching out from the body of the micelle into the surrounding fluid. These kappa- casein molecules all have a negative electrical charge and therefore repel each other, keeping the micelles separated under normal conditions and in a stable colloidalsuspension in the water- based surrounding fluid. These other proteins are more water- soluble than caseins and do not form larger structures. Because the proteins remain suspended in whey remaining when caseins coagulate into curds, they are collectively known as whey proteins. Whey proteins make up approximately 2. Lactoglobulin is the most common whey protein by a large margin. Calcium, phosphate, magnesium, sodium, potassium, citrate, and chlorine are all included as minerals and they typically occur at concentration of 5. The milk salts strongly interact with casein, most notably calcium phosphate. It is present in excess and often, much greater excess of solubility of solid calcium phosphate. Vitamins A, B6, B1. C, D, K, E, thiamine, niacin, biotin, riboflavin, folates, and pantothenic acid are all present in milk. Calcium phosphate structure. For many years the most accepted theory of the structure of a micelle was that it was composed of spherical casein aggregates, called submicelles, that were held together by calcium phosphate linkages. However, there are two recent models of the casein micelle that refute the distinct micellular structures within the micelle. The first theory attributed to de Kruif and Holt, proposes that nanoclusters of calcium phosphate and the phosphopeptide fraction of beta- casein are the centerpiece to micellular structure. Specifically in this view, unstructured proteins organize around the calcium phosphate giving rise to their structure and thus no specific structure is formed. The second theory proposed by Horne, the growth of calcium phosphate nanoclusters begins the process of micelle formation but is limited by binding phosphopeptide loop regions of the caseins. Once bound, protein- protein interactions are formed and polymerization occurs, in which K- casein is used as an end cap, to form micelles with trapped calcium phosphate nanoclusters. Some sources indicate that the trapped calcium phosphate is in the form of Ca. PO4)6; whereas, others say it is similar to the structure of the mineral brushite Ca. HPO4 - 2. H2. O. The lactose gives milk its sweet taste and contributes approximately 4. Lactose is a disaccharide composite of two simple sugars, glucose and galactose.
