The milking of cows was traditionally a labor-intensive operation and still is in less developed countries. Small farms need several people to milk and care for only a few dozen cows, though for many farms these employees have traditionally been the children of the farm family, giving rise to the term " family farm".

Milk preservation methods have improved starting with the arrival of refrigeration technology in the late 19th century, which included direct expansion refrigeration and the plate heat exchanger. These cooling methods allowed dairy farms to preserve milk by reducing spoiling due to bacterial growth and humidity.

Worldwide, leading dairy industries in many countries including India, the United States, China, and New Zealand serve as important producers, exporters, and importers of milk. Since the late 20th century, there has generally been an increase in total milk production worldwide, with around 827,884,000 tonnes of milk being produced in 2017 according to the FAO. 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 A portion of the population, [37] including vegans and many Jains, object to dairy production as unethical, cruel to animals, and environmentally deleterious. They do not consume dairy products. They state that cattle suffer under conditions employed by the dairy industry. [38] [39] The nutritional requirements of cattle are usually divided into maintenance requirements, which depend on the cow's weight; and milk production requirements, which in turn depend on the volume of milk the cow is producing. The nutritional contents of each available feed are used to formulate a diet that meets all nutritional needs in the most cost effective way. Notably, cattle must be fed a diet high in fiber to maintain a proper environment for the rumen microbes. Farmers typically grow their own forage for their cattle. Crops grown may include corn, alfalfa, timothy, wheat, oats, sorghum and clover. These plants are often processed after harvest to preserve or improve nutrient value and prevent spoiling. Corn, alfalfa, wheat, oats, and sorghum crops are often anaerobically fermented to create silage. Many crops such as alfalfa, timothy, oats, and clover are allowed to dry in the field after cutting before being baled into hay. Safeway milk free of bovine hormone".

Most dairy producers aim for a replacement heifer to give birth to her first calf, and thus join the milking herd, on her second birthday. As the cow's gestation period is a little over 9 months this means the cow must be inseminated by the age of 15 months. Because the breeding process is inefficient, most producers aim to first breed their heifers between 12 and 14 months. Before a heifer can be bred she must reach sexual maturity and attain the proper body condition to successfully bear a calf. Puberty in cattle depends largely on weight among other factors. [17] Holstein heifers reach puberty at an average body weight between 550 and 650 lbs. [17] Smaller breeds of cattle, such as Jerseys, usually reach puberty earlier at a lighter weight. [18] Under typical nutritional conditions, Holstein heifers will reach puberty at the age 9–10 months. Proper body condition for breeding is also largely judged by weight. At about 800lbs Holstein heifers will normally be able to carry a healthy calf and give birth with relative ease. [17] In this way, the heifers will be able to give birth and join the milking herd before their second birthday. [18] Estrous cycle [ edit ] Dairy cattle housing systems vary greatly throughout the world depending on the climate, dairy size, and feeding strategies. Housing must provide access to feed, water and protection from relevant environmental conditions. One issue for housing cattle is temperature extremes. Heat stress can decrease fertility and milk production in cattle. [11] Providing shade is a very common method for reducing heat stress. Barns may also incorporate fans or tunnel ventilation into the architecture of the barn structure. [12] Overly cold conditions, while rarely deadly for cattle, cause increases in maintenance energy requirements and thus increased feed intake and decreased milk production. [13] During the winter months, where temperatures are low enough, dairy cattle are often kept inside barns which are warmed by their collective body heat.Large quantitiescan be catered for and we are able to deliver to manufacturers, milkmen, coffee shops, hotels, farm shops, pubs and restaurants in York and the surrounding area. A consistent milking routine helps reduce the risk of mastitis spreading. Routines vary between farms, parlour types and different systems, but once cows are in the parlour, the main aim is to put clusters on clean, dry teats. Wash the teats, then wipe them dry with a clean dry cloth or towel. Only use single-use towels to avoid bacteria transferring between cows.
