> A cow couldn't have a calf if it hadn't become pregnant.

Not just that. A cow couldn't be a cow if she hadn't become pregnant.

I’m curious curious, what’s the English term for a female calf that lived more that two years and didn’t experience pregnancy? Never heard such a term in any language.

Heifer. Possibly freemartin under the right circumstances. Cattlebeast if you are looking for something more generic.
