Intentional notching isn't done on the ear tips by anyone that knows hogs. Ear notching was mainly done when hogs were "free ranged" then gathered later for slaughter...
Actually Brent, this is wrong. Ear notching can and is often done near the tips including removal of the tips. It is done for producing hogs and not just for "free ranged" hogs, by people who know what they are doing as well.

Ear notching isn't just to identify ownership of the pig, but particular litters and individuals within litters such that each pig can be properly identified as per status (age, sex, shots, medical treatments, etc.).
