A species is sometimes defined as a group of organisms capable of interbreeding and producing fertile offspring. Even though this definition is adequate, more precise or differing measures are often used, such as based on similarity of DNA or morphology.

So species might not be the best choice of words in this case, although anything is arguable :)

It refers to the male (bull) and female (cow) as a gender. In other words...

have no clue as to "why" :)
