It is important that you do not over work the bull, usually in a period of 8 hours about 3-5 is a good number for older bulls.

For a better understanding, the ideal bull to cow ratio would be for yearling bulls 15-20 cows. 2 year old bulls 20-30 cows; and for 3 year old or older 30-40. This ratio is usually for pasture breeding, when the cows and bull are turned out for the summer months when the bull will then breed them as they cycle.

How often can a bull breed?

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.


How many times a day can a bull mate?

It all depends on how many cows a bull has to settle in one day and how much libido the bull has. It should be safe to say that a bull may mate with one or more cows at least 10 to 20 times a day. If a bull has a lot of cows to breed, there's no time for eating, but lots of time for courting.


What is the function of a bull?

The function of a bull is to operate as half of your entire cow herd. In other words, his job is to breed your cows and sire as many offspring as he can in his lifetime with the many cows and heifers he is offered to service and as many cows and heifers allow his services.


How many panda cows are left in the world?

None. Cows are female and every cow hopes to meet a handsome bull.


How many cows can one bull breed?

Maximum is 25 to 50 cows in one breeding season. Younger yearling bulls tend to service 15 to 30 cows/heifers in one season. Some farms can only afford to have a bull per 10 cows if the pastures are too large for one bull to cover 20 or 50 females in one breeding season.


How many cows do you need to keep a bull?

A producer should have at least 25 to 50 cows to want to consider owning a bull. A cow herd that is much smaller than that should be bred by a leased bull from a neighbor or breeder that is not too far away, or artificially inseminated.


How many years does it take for a cow to become a bull?

A cow will never become a bull because cows are female cattle and bulls are male cattle.


How do you separate a bull from his cows?

There are many different methods of how producers separate their bulls from their cows. For those who don't have a big ranch, horses or dogs, it may be best to run the cows and bull through a handling facility where you can easily separate the bull into one pen while you run the cows through another. Of course this all depends on how well that facility is set up and the handling knowledge of the producer. If you have some good herding dogs and a trailer, you can separate the bull from his cows that way, having the dogs herd the bull to the trailer and you hauling away the bull to his normal bull-pen area. Or, if you're on horse-back and have the dogs with you, you can also have the dogs to herd the bull back to his pen, with you helping guide the dogs to where you want the bull to go. But if you have wild bulls to separate from the cows, then you'll probably need more help than some dogs. Get some cowboys to help get the bull separated away from his cows (and most likely get him loaded up in the trailer to get sold at the auction mart).


Why do farmers use a champion bull to provide sperm?

Because that bull is the best sire, bar none, for improving the kind of cows that the bull is to be bred to. He is a top quality sire, both in temperament and in conformational quality, and one that should be used on as many cows as he can service in a breeding season.


How may cattle can one Dexter bull service?

How many bulls should you have on a farm?

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.


What are the instincts of a bull on a farm?

To mate with as many cows as he can before he succumbs to exhaustion or injury or until the farmer determines when the bull should be pulled from the cow herd.
