The astonishing animal skirmish was caught on camera by a shocked passer-by and has lit up the web after being posted online.
It begins showing two bulls and a goat standing in a sun-kissed field apparently minding their own business.
But suddenly tempers begin to flare between the two species and the bull charges towards the goat.
Not one to back down from a challenge, the goat responds by running towards its aggressor, head bowed and raging.
They connect with a fierce “crack” and both drop to the ground.
The bull looks to be completely unconscious – but the dazed goat quickly gets back to its feet having emerged the shock victor in the outrageous battle.
Thousands have seen the stunning face-off since it was posted on social media site Reddit earlier this week, although details about the location and time that the video was shot are unknown.
“That’s the funniest s*** I’ve seen all week,” wrote one viewer.
Another simply said: “Goats are awesome.”
