Here is an article about a dairy farmer who says his Holsteins produce 10 gallons a day each:

However, I suspect this is the high end of milk production and requires giving the cows hormones (BGH) to achieve those yields, because of the following description of a 1920s Holstein herd: http://content.cdlib.org/ark:/13030/tf109nb1qf/
It says, "High grade Holstein herd. F. E. Baxter Ranch. The production of these cows during the summer of 1921 averaged 80 gallons per day for 20 head." So, that would be 4 gallons a day per cow, during peak (summer) production back when BGH was not available. Of course, breeding has also probably increased milk productivity since then, as well.
Typically about 30 to 35 liters per day. Can be as high as 40 liters per day.

Holstein cows produce an average of 3.5% butterfat with an average of 17,000 pounds of fluid milk per year. That would be 595 pounds of butterfat per year. Holsteins are the highest total fluid milk producers, but are on the low side of percent butterfat and percent protein. Even so, if you compare Holsteins to breeds that produce higher butterfat (like Jerseys and Guernseys), the Holstein will produce more total butterfat in a year due to the higher volume of fluid milk that they produce.
5,000 Litres per year
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.
usually about anywhere from 50 to 60 pounds twice a day but if u have a good cow she will give 70 to 80
In India, a person can expect to pay between 35,000 and 40,000 Rupees for a Holstein cow. The price you pay will be determined by the heritage of the animal, usual milk output, and other factors.
No. Female humans do not have the capacity to produce that much milk. Humans are not cows.
Jerseys produce around an average of 20,000 to 30,000 litres of milk per year.
Friesians are black and white and produce lots of milk Herefords are brown, much furrier and are bred for meat
It requires 88 pounds of feed to produce 100 pounds of milk
Because their milk is in much higher demand than human milk.
A Belted Galloway cow can produce as much as 20,000 lbs. of milk per year or 9,000 liters of milk per lactation. The milk has very small fat globules which renders it partially homogenized.
