In past articles we’ve discussed the history of marking livestock for identification purposes, from branding to ear tags to RFID (radio frequency identification). Many of these methods, while effective, are also often permanent in nature, which may not be desirable. They may even involve minor injury to the animal or damage to the skin or coat. But what if you don’t want the I.D. to be permanent (much less cause any pain to the animal)? That is where Ketchum livestock markers prove their worth!
