What about nouns, instead of adjectives, for a particular animal species of a particular age and/or gender? For example, "horse" includes mare, stallion, colt, filly, and foal. There must be numerous others, beyond the obvious ones.

The subject inevitably involves animal husbandry, and so may prove stimulating.

(edit) My spouse points out that the above example notes only two genders; it ignores a third gender, exemplified by the term "gelding". (Draw no implications from the fact that it was my spouse who noted this.)
