Because their milk is in much higher demand than human milk.
No. Female humans do not have the capacity to produce that much milk. Humans are not cows.
Cows produce more milk in new zealand.
No, they generally both graze on grass. Cows produce whole milk; humans turn it into 2% by removing milkfat down to that level. It's healthier and the milkfat can then be used for other things, like butter.
Cows don't lay eggs, or milk duds. Cows have calves and produce milk. Bulls produce semen to fertilize the cows.
Dairy cows are bred to produce vast quantities of milk. They are also bred to be quite docile around humans.
Today, modern dairy cows are bred specifically to produce large quantities of milk. Like humans, cows only produce milk after they have given birth, and dairy cows must give birth to one calf per year in order to continue producing milk. Typically they are artificially inseminated within three months of giving birth.
Cows don't give nectar, they give milk. Cows are mammals, not plants or flowers. However, there is a particular insect that farms another insect for its nectar, and these would be ants farming aphids and milking them like humans milk cows. Once the aphids are done producing, the ants eat them, also just like what humans do with cows when they cannot produce milk anymore.

Yes, cows typically produce more milk than calves need, as they are bred to produce milk for human consumption as well.
No, male cows cannot produce milk. Milk production is a function of female cows, specifically those that have given birth and are lactating.

All cows (those female bovines that have had at least 1 calf) produce milk, whether it's for human consumption or not. However, "dry cows" are cows that do not produce milk, whether they are bred or open and don't have a calf at side.
