Previously, at the slaughterhouses, so that the cows were not afraid to go to the cattle slaughter shop, a specially trained goat was released. The goat was walking in the workshop, and the cows, seeing that he was not afraid, followed him. Then the goats were taken away, and the herd was slaughtered.
The profession of a goat was such a goat provocator.
So you look at the advertisement of some shit, and there are always showing the goat of the provocator, who bleeds, like out like all the nuts, I use and normal. And the herd is kept, because the goat is known to all, and all so beautiful, well-maintained, so it needs us.
