Foal

because to farmers, 'cow' only refers to female cattle that have given birth! a heifer is a female that hasn't, a steer/ox is a castrated male, a freemartin is a female that was masculinized in the womb, a bull is an uncastrated male.... blablabla!

to add another layer, 'cow' and 'bull' arent labels exclusive to cattle! a female yak (that has had a calf) would be called a cow, while a(n uncastrated) male yak would be called a bull!

but those distinctions dont really matter if you're not the one keeping the animals. to the average person a bull would be considered a cow, because that's just the word a lot of people use for cattle! i dont think arguing over what 'cow' really means is useful because, just like all language, people use it differently!

thanks for coming to my ted talk. :3
