Animals know what will happen to them.

The poor man was old and very indebted, so he accepted to be sold like an animal. What it did not imagine is that who would buy him would be a meat producer. It arrived at the slaughterhouse thin and weak, for weeks it has been kept confined and well-fed. Then it will be castrated to make it even fatter for a few more weeks and then shot down with a hammer.

Animals know what will happen to them. The day before, they already stick a thick plastic tube into your urethra and tied their balls and dick to interrupt circulation and facilitate castration. With these precautions, castration is a very quick, simple and almost painless intervention. Everything that is cut is mixed in the cattle feed the next day. It is not uncommon for castrated animals to find their parts in the middle of their food. No waste, nothing is lost.

The experienced veterinarian likes to look deeply into the animal's eyes and then quickly pulls out the penis and deftly cuts the balls first and then the base of the dick in two fast movements.
Some of them don't even notice what was extracted. They only cry and despair when the vet shows the parts in his hand.
