Due to the lack of a reliable source of data on worldwide cattle population, and the number of variables affecting how often an individual cow will give birth it is extremely hard to provide an accurate figure for births/minute.
Cows generally produce one calf each year, although they can sometimes have twins, or more rarely triplets.
This depends on the breed of the cow, her age, what breed or type of bull she was bred to, her condition, etc. Offspring of cattle are called calves, by the way.
they have three or maybe five
1 calf per year.
As often as possible and as often as there are cows that are needing his services. That said, a bull can breed as many as 2 to 10 cows (or more) per day, depending on how many cows are in heat on that day.

It depends, Many dairies have no bulls on the farm and all breeding is done by artificial insemination. Most small farms only need one bull, especially if the bull is with the cows all year round and you don't have a defined breeding season. Things you need to take into account though are the age of the bull and if the cows are synchronized. You also need to account for how much land the cow are out on. If the bull is two years old you want to give him about 20 cows. Three or four year olds could probably have up to 40 cows. You definitely don't want to go over 50 cows. If the bull is old you probably want to decrease cows too. If the cows are syncronized you need more bulls because the cows are all coming into heat about the same time. You probably want to have 10-15 cows per bull. If the cows are out on range and it is difficult for them to move around you need less cows per bull. You also want to have your bulls tested each year for venereal diseases, semen count and motility. Also watch for lameness and if they are in good shape going into the breeding season. If he can't get to the cows then he can't breed them. One last thing if you are on a small farm with only one bull make sure you don't breed him to his daughters or granddaughters! Try AI, or a new bull or sell all related heifers.

Many cows in the world will eat zero bushels per year per head. Cows in the states fed a supplement of corn may only consume five to ten bushels of corn a year per head. Still others that are in a intensive commercial operation may eat anywhere from 50 to 200 bushels of corn per year, if not more, and depending on the weight, class, age, breed and type of cows being fed, as well as what other feedstuffs are fed in addition to corn.
Any cow can have a calf per year, usually cows will be able to breed and produce calves until they are 7-10 years of age.
1 calf per year.
The Collared Lemming has about 4 young per litter. Information from a 15 year study by Olivier Gilg.

None. Cows are not plants: they do not need fertilizer.
Normally 2 per year but 3 can also be a normal for some pairs
