They don't, certainly not by choice. They are built to give their calves milk, not humans. It's us humans who have chosen to take advantage and manipulate cows so that they produce more milk than their calves need so that we can take it and drink it or make other food products from it.
All of them.
However, if you are referring specifically to those breeds that are bred and raised to produce milk, they would be Holstein, Jersey, Guernsey, Ayrshire, Milking Devon, Brown Swiss, Montbeliard, Canadienne, Dutch Belted, Milking Shorthorn and many others.
All girl cows not the boys though.
Dairy Cow
Jerseys.
The udder.
Holsteins.
Yes, there are plenty of Zebu-related breeds like those in India and Africa that are used for milk production. They can produce milk just as well as any other cow, even though they won't produce as much as the famous Holstein.
If you are refering to raw milk, different breeds of cows will produce different cream or fat content and this will vary cow to cow in a given breed. Processed milk has different fat content for consumer preference.
This depends on what is regarded as the most desirable trait. The Holstein cow is known for producing a large amount of milk. The Guernsey is known for producing milk with a rich flavor. The Jersey cows produce milk with a very high butterfat content. Some cows, such as the Ayrshire and Milking Shorthorn are more efficient in producing milk from the amount of feed they get. There are many other breeds with special advantages, such as Indian breeds that can live and produce milk in marginal dry and hot lands.

Answer: None. No milk can produce a cow. But, a cow can produce milk, and depending on the breed! A cow can produce anywhere from 10 to 20 pounds of milk per day (typical beef breeds) to over 40 pounds (typical dairy breeds like the Holstein).
Holstein Friesian cattle
A dairy cow. Holsteins are the largest milk producers of all dairy breeds.
They produce milk just like any other cow that is pregnant or not.
holstine
No
holstein cows are known for their high quantity of milk production although other breeds of dairy cattle produce a higher quality or butter fat content than the holstein. the jersey cow is one example of milk cow that produced a lot of cream in the milk.
Yes they do.
