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.
breed and and graze
Most bulls will be on the farm/ranch until they're around 4 or 5 years old. By that time they start getting ornery and aggressive and need to be shipped to slaughter. Some bulls, however, will not get this way and live to be still productive past 15 years of age.
Stud bulls can be referred to as follows: bulls leased out to another breeder, or bulls used in an AI (artificial insemination) program which these bulls' semen are stored to be used on many different cows in distant locations.
A female seal is referred to as a cow, similar to farm female cows. Bulls are male cows as with seals also.
One word: TESTOSTERONE. Bulls are dangerous and unpredictable because of one of two things: jealousy and protection over their girls (the cows), and because they really really want to eat. Bulls that can smell a cow in heat and are being herded through a corral can become quite exited, and do as best as he can to get to that cow that "needs" him. Bulls are also dangerous if they don't respect you, and if they realize they are bigger and stronger than you and constantly challenge you. Challenging bulls get a one-way ticket to the slaughterhouse on my farm.

Because.
Horses, ox, and sometimes domestic bulls.
To breed the cows. Bulls, when it is time to cull them, are then turned into beef.
In my own experence. Chickens!
