An ox (: oxen), also known as a bullock (in British, Australian, and Indian English), is a large bovine, trained and used as a draft animal. Oxen are commonly castrated adult male cattle, because castration inhibits testosterone and aggression, which makes the males docile and safer to work with. Cows (intact females) or bulls (intact males) may also be used in some areas.
