heifer

This term is a precise agricultural designation used to distinguish a young female bovine from a cow. The primary distinction is reproductive history; once a heifer has calved for the first time, she is reclassified as a cow.

In a social or colloquial context, the word is sometimes used as a derogatory slur to describe a woman as overweight or clumsy, though this usage is considered offensive and deviates from the technical livestock meaning.
