Ox emoji depicts the male representative of the same animal species as the Cow emoji does. The ox doesn't give milk so it is used in farming for other purposes like plowing or carrying heavy things. Also, ox is in no way an insult or anything like that - so this emoji is used quite rarely and always in its direct meaning of indicating a huge, strong domesticated animal. Also, it may be used in relations to mascots and logos.
