(Clarification) It seems like you are asking what terms refer to different categories of cows.
The term "chickens" can be used as a general term for all members of the chicken species, including chicks (baby chickens), hens (adult female chickens), and roosters (adult male chickens). Similarly, you are wondering about the terms that categorize different types of cows.
The term "cows" generally refers to adult female cattle, while "bulls" refer to adult male cattle. However, the term "calves" is used to describe young cattle of either sex, typically under one year old. So, to summarize, the terms "cows," "bulls," and "calves" are used to categorize different types of cattle.
