A yearling bull, which is best used on heifers, can breed from 10 to 20 heifers in a breeding season.
Depends on the bull. Usually a bull can service up to 25 females in a single breeding period; others can breed 50 if they have high libido.
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.
At least ONE bull along with other cows and maybe some heifers. The herd of a cow can also be all cows or all heifers. A herd of cattle can comprise both those as well as all bulls or all steers. A cow herd does not have to have a bunch of cows with at least one bull in it.
Yes.
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.

Since yearling bulls are the best to use on heifers, and one yearling bull will breed from 15 to 20 heifers, you should have 4 bulls for your herd of 70 heifers.
Jerseys are one such breed.

There are a lot more reasons than one may realize. A bull may be a "crypto" bull, or have his testes up close to his body (they haven't completely descended) causing the testes to have too high a temperature and unable to produce fertile sperm. He can breed, he just will be "shooting blanks." Other reasons are as follows:Injury to the penis (most common injury is a broken penis)Genetic condition causing the bull to be sterile, such as crooked or corkscrew penis, abnormal sperm, erectile dysfunction, etc.Malnutrition decreasing fertility of the bullLeg/spinal/hoof injury, making the bull be unable to mount and breed cows and heifers successfullyIntense competition from other bulls, giving them no chance to settle any cows or heifers of their ownBull is too young to be breeding cows/heifersCompetition between bulls of same age, size, breed, status induces more fighting than breeding.Illness or disease can cause a bull to become infertileCastration. A bull that is castrated will no longer be able to breed cows.Other factors remain unsaid, but these are the most common.
They cannot breed with one another.
There are a few dog breeds that can be put under the term 'pit bull': American pit bull terrier American staffordshire terrier Staffordshire bull terrier and there is a breed called Irish staffordshire bull terrier People argue that the APBT and the Amstaff are one and the same breed, but others argue that the bloodlines have been apart too long for them to be considered the same breed.
A Crossbreed, neither one breed or another

One bull testicle (depending on the size and the breed of bull you are referring to) can weigh around 1 to 2 lbs.
