Sorry, this blog isn’t about that time you and your friends went out and drank way too much and on a dare you all ended up getting a bunch of truly horrible tattoos that you really, really regretted the next morning, and now you’re desperate to get yours removed before your mom or your girlfriend sees it. If that’s what you’re looking for, you’ve come to the wrong place.
No, this is actually about domesticated hogs and the various ways a pig farmer can easily identify individual animals within a drove for later processing—specifically, by tattooing a series of numbers and/or letters on the pig’s ear or shoulder or back. For the ear, you use a special ear tattoo plier; and for the back or shoulder, you use a hog shoulder-slapper.
Both tools use special metal needlepoint alphanumeric characters, called dies, that can be slipped in and out of the applicator as needed. Last but not least, you need livestock tattoo ink, which comes in green or black colors.
