Best Answer

A tagger, a tool that kinda looks like a singular paper hole puncher only with points on the end, is used. The main tag itself is put on one point, and the back part of the tag on the other point, with the ends of either parts pointing towards each other. On the ear of the cow is an area where there are no major blood vessels, which is always right in the middle of the cow's ear. The tagger points are put here, and the tagger squeezed together until the two parts of the ear tag connect. The tagger is released, and the ear tag is in place.

Placing plastic or metal tags into a cow's ear(s) allows the farmer/owner to identify the cow from a distance. It provides for reasonably stable individual identification of the animal.

Why are goat ears cropped?

As a rule, goats' ears are not cropped. Sometimes goats with floppy ears have their ears caught in a fence or pull the tags out, and that tears them.There is one breed of goats that has ears (the external, floppy part) that are very short or nonexistent, and that is the LaMancha.
