Sow IS female/feminine. The male pig/swine is a boar.
The boar is a male pig; the female is called a sow
female
The sow is a female pig and a boar is the male.
That would be the sow, the female of the species.
There is no such thing. Pig is a word that describes an omnivorous mammal with a stout body, cloven hooves on each foot and a broad cylindrical snout, it does not describe the sex or gender of an animal.However, the male gender of a pig is a boar (intact male) or a barrow (castrated male), and the female is a sow(mature female) or gilt (immature female).

The opposite of he-bear would be 'she-bear' - but neither is necessarily correct. I think it should be male bear and sow.
