History

The 1st goats were domesticated around 7000 B.C. in Iran, and cattle a little later, around 6000 B.C. in Greece. It is not certain when humans 1st started milking their domesticated animals. One of the earliest milking scenes in existence today, which shows a goat being milked, is on an Elamite seal from 2500 B.C. Milk, especially in its soured forms, as cheese, yogurt, etc., made a big difference in the life of Neolithic man, providing all-season, high-quality food that sustained him when the growing season was over, when he could no longer collect leaves and berries, and when food was scarce. Sanskrit records mentioned milk 6,000 years ago. The Bible describes the Promised Land as a land flowing with milk and honey. Some 2,300 years ago, the Greek physician Hippocrates recommended milk as a medicine. Christopher Columbus brought cattle to the New World on his second voyage. Fermented products such as cheeses were discovered by accident, but their history has also been documented for many centuries. Historically, the milking and the processing took place close together in space and time: on a dairy farm. People milked the animals by hand; on farms where only small numbers are kept, hand-milking may still be practiced. In 1937, it was found that bovine somatotropin (bST or bovine growth hormone) would increase the yield of milk. Monsanto Company developed a synthetic (recombinant) version of this hormone (rBST). In February 1994, rBST was approved by the Food and Drug Administration (FDA) for use in the U.S. It has become common in the U.S., but not elsewhere, to inject it into dairy cows to increase their production by up to 15%.

INTRODUCTION

A dairy is a facility for the extraction and processing of animal milk mostly from cows or goats, but also from buffalo, sheep, goat or camels for human consumption. Typically it is a farm (dairy farm) or section of a farm that is concerned with the production of milk, butter and cheese. Dairy farming is a class of agricultural, or an animal husbandry, enterprise, for long-term production of milk, usually from dairy cows but also from goats and sheep, which may be either processed on-site or transported to a dairy factory for processing and eventual retail sale. Most dairy farms sell the male calves born by their cows, usually for veal production, or breeding depending on quality of the bull calf, rather than raising non-milk-producing stock. The word dairy refers to milk-based products, derivatives and processes, and the animals and workers involved in their production: for example dairy cattle, dairy goat. A dairy farm produces milk and a dairy factory processes it into a variety of dairy products. These establishments constitute the dairy industry, a component of the food industry. India is the largest producer of milk producing more than 100 million tons of milk per annum. Yet, her per capita milk consumption is around 250 g per day. India has a population of more than 1 billion with diverse food habits, cultures, traditions and religions. Regional variations within the country can be mind boggling. On one hand, the country has plains with long tradition of milk production and consumption. On the other hand, there are forest and hilly regions with no tradition of dairying. Most of coastal belts also do not have much of dairy tradition. Cow is holy for Hindus who make up more than 80 per cent of the population of India. Buffalo enjoys no such holy status. Cow slaughter is banned in many states of India. There are no restrictions on buffalo culling. Technological advances have only come about very recently in the history of milk consumption, and our generations will be the ones credited for having turned milk processing from an art to a science. The availability and distribution of milk and milk products today in the modern world is a blend of the centuries old knowledge of traditional milk products with the application of modern science and technology. The role of milk in the traditional diet has varied greatly in different regions of the world.

The Bangalore Dairy, which began processing milk in 1965 with an initial capacity of 50,000 Litres Per Day(LPD), was inaugurated on 23.1.1965 by late Sri.Lal Bahadur Shastriji, the then Hon'ble Prime Minister of India. Later the capacity was enhanced to 3.50 Lakh Litres Per Day. Steady demand for quality milk, led the organization to break ground on its newest Mega Dairy, commissioned during the year 2000, which is a modern & fully automated dairy plant with a capacity of 6.00 Lakh Litres Per Day is expandable to 10 Lakh Litres Per Day. The operations in the Dairy are fully computerised and each operation is automated with controls for standardization, temperature & flow control, pasteurization and clearing-inplace (CIP) system. The system also gathers and distributes data for production, maintenance, breakdown, quality, CIP, along with utility and water supply system measurements for analysis & monitoring. The Union has Chilling Centres at Doddaballapur, Anekal, Hoskote, Vijayapura, Solur, Byrapatna and Kanakapura in Bangalore District with total chilling capacity of 5.5 Lakh Litres Per Day. There are 113 Bulk Milk Coolers & 479 Automatic Milk Collection Units in the Union. The Milk union is procuring an average of 8.59 Lakh Kgs. per day and selling 6.59 Lakh Litres everyday through Retailers, Franchisee Outlets and Day Counters. Bangalore Milk Union, Ltd. uses an integrated CIP and process control system to realize a savings of $444,000 annually in water and energy costs. Not all food and beverage applications lend themselves to automated clean-in-place (CIP) systems, but those that do can benefit in the savings of time, water, energy, chemicals and money.

Industrial Processing of Milk Hand milking Centralized dairy farming as we understand it primarily developed around villages and cities, where residents were unable to have cows of their own due to a lack of grazing land. Near the town, farmers could make some extra money on the side by having additional animals and selling the milk in town. The dairy farmers would fill barrels with milk in the morning and bring it to market on a wagon. Until the late 1800s, the milking of the cow was done by hand. In the United States, several large dairy operations existed in some northeastern states and in the west, that involved as many as several hundred cows, but an individual milker could not be expected to milk more than a dozen cows a day. Smaller operations predominated. Milking took place indoors with the cattle tied by the neck with ropes or held in place by stanchions. Feeding could occur simultaneously with milking in the barn, although most dairy cattle were pastured during the day between milkings. Vacuum bucket milking The first milking machines were an extension of the traditional milking pail. The early milker device fit on top of a regular milk pail and sat on the floor under the cow. Following each cow being milked, the bucket would be dumped into a holding tank. This developed into the Surge hanging milker. Prior to milking a cow, a large wide leather strap called a surcingle was put around the cow, across the cow's lower back. The milker device and collection tank hung underneath the cow from the strap. This innovation allowed the cow to move around naturally during the milking process rather than having to stand perfectly still over a bucket on the floor. With the availability of electric power and suction milking machines, the production levels that were possible in stanchion barns increased but the scale of the operations continued to be limited by the labor intensive nature of the milking process. Attaching and removing milking machines involved repeated heavy lifting of the machinery and its contents several times per cow and the pouring of the milk into milk cans. As a result, it was rare to find single-farmer operations of more than 50 head of cattle.

Step-Saver milk transport

As herd size began to increase, the bucket milker system became laborious. A vacuum milktransport system known as the Step-Saver was developed to transport milk to the storage tank. The system used a long vacuum hose coiled around a receiver cart, and connected to a vacuumbreaker device in the milkhouse, allowing farmers to milk many cows without the necessity of walking increasingly longer distances carrying heavy buckets of milk. Milking parlors Innovation in milking focused on mechanising the milking parlour to maximise throughput of cows per operator which streamlined the milking process to permit cows to be milked as if on an assembly line, and to reduce physical stresses on the farmer by putting the cows on a platform slightly above the person milking the cows to eliminate having to constantly bend over. Many older and smaller farms still have tie-stall or stanchion barns, but worldwide a majority of commercial farms have parlours. The milking parlor allowed a concentration of money into a small area, so that more technical monitoring and measuring equipment could be devoted to each milking station in the parlor. Rather than simply milking into a common pipeline for example, the parlor can be equipped with fixed measurement systems that monitor milk volume and record milking statistics for each animal. Tags on the animals allow the parlor system to automatically identify each animal as it enters the parlor. Fully automated robotic milking In the 1980s and 1990s, robotic milking systems were developed and introduced (principally in the EU). Thousands of these systems are now in routine operation. In these systems the cow has a high degree of autonomy to choose her time of milking within pre-defined windows. These systems are generally limited to intensively managed systems although research continues to match them to the requirements of grazing ca
