What is the term for a male cattle that has been castrated?

Explanation

The correct term for a castrated male cattle is 'Bullock'. A 'Bull' refers to an intact male, while 'Steer' and 'Ox' can also denote castrated males, but 'Bullock' is the most specific term in this context. 'Burdizo' is a tool used for castration, not the animal itself.
