A bull is 51 when he stops breeding in bull years
The breeding male of a cow is called a bull.
Often a bull should stop breeding either if he's too old and not fertile enough any more to be used, or if he's become too aggressive and dominant with his handlers to be considered a keeper anymore. There really is no defined age when a bull should stop breeding.
Herd bull, stud bull, etc.
Generally, a bull should be at least 12-15 months old before breeding to a cow, as younger bulls may not have reached full maturity and could struggle with mating. Breeding a 6 month old bull to a cow could result in unsuccessful mating, injury to the animals, or health issues for the offspring. It is advisable to wait until the bull is older and has reached breeding maturity before attempting mating.
Just like with cows, a bull is culled based on conformation, temperament, fertility, health issues and breeding ability. A bull can be too old to breed when he's 5 yrs old or at least 15 years of age.
A bull can typically be used for breeding purposes until it is around 6 to 7 years old, although some can remain fertile into their early teens. Factors such as health, genetics, and management practices can influence a bull's breeding longevity. Regular health checks and monitoring of fertility are important to ensure effective breeding. After reaching a certain age or if fertility declines, it may be time to retire the bull from breeding duties.

Simmental bull calves will reach puberty when they get to be around 10 months of age, and are commonly used for breeding when they are past 12 months old.
A 20 month-old bull should be able to breed around 10 to 30 cows in a breeding season. The most may be 40, but that could be pushing it.
That breed is alive and breeding. The only bull breed extincted is the Cuban pit bull.
A bull can typically be used for breeding for about 5 to 7 years, although this can vary based on the bull's health, genetics, and breeding management practices. Some bulls may remain effective breeders for longer, but their fertility and overall performance may decline with age. Regular evaluation of the bull's reproductive capabilities is important to ensure optimal breeding success.
It is generally recommended to wait until a male pit bull is at least 18-24 months old before breeding. Breeding at 11 months old may not allow the dog to fully mature physically and behaviorally, leading to potential health risks for the dog and offspring. It is important to consult with a veterinarian or a professional breeder to determine the best age for breeding.
