Ellingson JL; Anderson JL; Koziczkowski JJ; etal. (May 2005). "Detection of viable Mycobacterium avium subsp. paratuberculosis in retail pasteurized whole milk by two culture methods and PCR". J. Food Prot. Journal of Food Protection, United States. 68 (5): 966–72. doi: 10.4315/0362-028x-68.5.966. PMID 15895728. While cattle were domesticated as early as 12,000 years ago as a food source and as beasts of burden, the earliest evidence of using domesticated cows for dairy production is from the seventh millennium BC – the early Neolithic era – in northwestern Anatolia. [2] Dairy farming developed elsewhere in the world in subsequent centuries: the sixth millennium BC in eastern Europe, the fifth millennium BC in Africa, and the fourth millennium BC in Britain and Northern Europe.

Milking machines are held in place automatically by a vacuum system that draws the ambient air pressure down from 15 to 21 pounds per square inch (100 to 140kPa) of vacuum. The vacuum is also used to lift milk vertically through small diameter hoses, into the receiving can. A milk lift pump draws the milk from the receiving can through large diameter stainless steel piping, through the plate cooler, then into a refrigerated bulk tank. Wash the parlour between rows, and don’t wash while cows are in the parlour unless all the units are attached to cows. Use running water and disinfectant solution to remove infected milk from gloves, liners and other equipment. A good milking routine In the United States a dairy can also be a place that processes, distributes and sells dairy products, or a room, building or establishment where milk is stored and processed into milk products, such as butter or cheese. In New Zealand English the singular use of the word dairy almost exclusively refers to a corner shop, or superette. This usage is historical as such shops were a common place for the public to buy milk products. Attach the cluster unit, ensuring the clusters are squarely attached, aligned and balanced centrally. If you have automatic cluster removers (ACRs), pull the cord , so it is not under tension. Never apply weights to clusters At 1pm daily you can see some of our cows being milked. Enjoy a short talk whilst watching the cows enter the abreast parlour. You have a great view from our viewing gallery and you can listen to our farmers explaining the process and how we have done it for the last 30 years. The farmer may even tell a few (bad!) jokes! This demonstration really is educational for all ages and we guarantee you will leave this area having learnt something new. Calf Feeding

Dairy farming has been part of agriculture for thousands of years. Historically it has been one part of small, diverse farms. In the last century or so larger farms concentrating on dairy production emerged. Large scale dairy farming is only viable where either a large amount of milk is required for production of more durable dairy products such as cheese, butter, etc. or there is a substantial market of people with cash to buy milk, but no cows of their own. Dairy farms were the best way to meet demand. Although any mammal can produce milk, commercial dairy farms are typically one-species enterprises. In developed countries, dairy farms typically consist of high producing dairy cows. Other species used in commercial dairy farming include goats, sheep, water buffaloes, and camels. In Italy, donkey dairies are growing in popularity to produce an alternative milk source for human infants. [1] History [ edit ] Milking cattle in ancient Egypt Cowpox is a virus that today is rarely found in either cows or humans. It is a historically important disease, as it led to the first vaccination against the now eradicated smallpox. Field, Thomas; Taylor, Robert (2008).

The production of milk requires that the cow be in lactation, which is a result of the cow having given birth to a calf. The cycle of insemination, pregnancy, parturition, and lactation, followed by a "dry" period of about two months of forty-five to fifty days, before calving which allows udder tissue to regenerate. A dry period that falls outside this time frame can result in decreased milk production in subsequent lactation. [36] Hermon-Taylor, John (14 July 2009).

PMID 19602288.The holding yard at the entrance of the shed is important as a means of keeping cows moving into the shed. Most yards have a powered gate that ensures that the cows are kept close to the shed.
