Biting the tail
In Pacu Jawi (Indonesian cow race), coupled cows run along the muddy field about 20-30 meters long. Each couple is steered by a jockey with his hands on the cows’ tails and his feet on the wooden contraption that bind the cows together. The jockey bites one of the cows’ tip of the tail to make it run, automatically followed by the other one. The jockey often has to bite the tail again in the middle of the race to make the cows go faster.
