Ox:
* General term: An adult male castrated bovine.
* Used for work: Historically, oxen were primarily used for labor, pulling plows, carts, and other heavy loads.
* More mature: Oxen are typically older than bullocks and have been trained for work.
Bullock:
* Young, uncastrated male: A bullock is a young, uncastrated male bovine.
* Potential for breeding: A bullock can be raised to become a breeding bull.
* May be used for work: While not always the case, bullocks can be used for work, particularly in areas where oxen are not readily available.
In summary:
* Ox: Castrated, adult male, used primarily for work.
* Bullock: Uncastrated, young male, potential for breeding, may be used for work.
It's important to note that the terms can be used loosely depending on the context and region. In some areas, "bullock" might refer to any young male bovine, regardless of castration.
