Well no one ever organized a horse fights, but bull fights were quite popular through-out the Europe. And even goats are far from friendly, unless they're accustomed to having a lot of people around. Pretty much any farm animal that's used to being handled by one or two people max, will be very shy and sometimes aggressive (especially when they have babies) about any new face. Smaller animals reaction will be to run away form you, but large ones will stand and fight. And when a cow lowers its head to show you the horns, it can get pretty tense, believe me :)
