Ruling on cutting part of the ears of livestock to increase their price

What is the ruling on cutting part of the ears of livestock and goats on the grounds that their shape makes them desirable for sale and increases their price?
There is nothing wrong with that, provided that it does not cause them pain,Meaning: that the area from which one intends to cut is numbed so that they do not suffer pain. For this reason, it is permissible for us to brand animals with a mark to preserve them so that they do not get lost.
