The term itself represents masculine in the gender class of different animals. Here in the case of deer, it is specific for the mature ones not for young ones. It is dependent on species of deer also.

The bull is a term used for male bovine animals. This term is not exactly used for male deer but for antelopes. Antelopes are deer-like animals. We can say this term is for naming males of deer-like animals but not exactly for deer.
