The etymology of the term "freemartin" is uncertain: speculations include that "free" may indicate "willing" (referring to the freemartin's willingness to work) or "exempt from reproduction" (referring to its sterility, or to a farmer's decision to not bother trying to breed a freemartin, or both), or that it may be derived from a Flemish word for a cow which gives no milk and/or has ceased to ...
It has been bred selectively to produce the highest yields of milk of any cow. The average in the UK is around 22 litres per day. [102] [103] Dairy is a large industry worldwide. In 2023, the 27 European Union countries produced 143 million tons of cow's milk; the United States 104.1 million tons; and India 99.5 million tons. [107]
Cow blowing, [1] Kuhblasen, [2] phooka, or doom dev [3] is a process in which a farmer forcefully blows air into a cow's vulva or anus to supposedly induce her to produce more milk. A tube may be used to provide some sanitary separation between the blower and the cow, although not every culture that practices cow blowing does so.

The milk is filtered and cooled before being added to a large bulk tank of milk for storage. [3] The average time of milking is 5–7 minutes and a cow can be milked with a machine 2–3 times a day. [4] The existing robotic milking has allowed cows to have the freedom to decide when to milk, but still needs to make contact with people. [5] [6]
During pregnancy, the udder begins to develop further. After calving, a cow will nurse its calf briefly and then typically be milked two to three times daily. Cows produce about 80 pounds of milk per day, though some can produce well over 100 pounds. After a cow becomes pregnant again, it will be "dried off"—meaning it will stop being milked ...
