It depends on what you are using the bull for. If he's used for producing daughters, then he must have his dam's qualities for milking ability, mothering ability, calving ease, femininity (reflected by the bull's masculinity), good pelvic area, and high fertility.
If he's used as a terminal sire (for selling calves for slaughter as beefers), he must produce calves with heavy weaning and yearling weights, good feed convertability, good rate of gain, adequate rib-eye area, and marbling.
A stud bull is a male breeding bull that is chosen for its desirable genetic qualities, such as strength, size, and temperament, in order to produce offspring with similar positive traits. Stud bulls are used specifically for breeding purposes to improve the quality of a herd or population.

Size doesn't matter in this scenario. A bull will reach is terminal (or mature) weight by the time he reaches 3 to 4 years of age, and can continue to be used for breeding, as long as he's got good fertility and libido, and doesn't challenge the owner in any way, for up to 15 years of age.

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.
Herd bull, stud bull, etc.
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.
The preferred breeding combination is generally a male Boerboel and a female Bull Mastiff. This pairing is often favored because it can help mitigate health risks associated with breeding large breeds, as the female Bull Mastiff may be better equipped for carrying and delivering larger litters. Additionally, this combination can result in puppies that inherit desirable traits from both breeds, such as the Boerboel's protective nature and the Bull Mastiff's gentle temperament.
That breed is alive and breeding. The only bull breed extincted is the Cuban pit bull.
