I've seen plenty of the Ketchum metal tags lost too Allfarmer. Biggest problem is the person applying them has to leave enough room for the ear to grow - if you don't they can tear out as the ear grows - at the same time if you leave too much room for growth the tags can move about and you finish up with them revolving in the ear. Quite often this gets infected and the hole enlarges. Other problems are pail bunter calves that suck on the others ears and also the tags wearing through at the outside edge of the ear - typically happens with cattle confined in barns with concrete walls or tie stall posts to rub on. Tends to be an old cow problem but it does happen!
I really like the EID type plastic tag installed inside the ear away from sucking, rubbing or catching on things. We have better retention on EIDs than we had on ketchums metal tags and they were the staple for decades in the UK.
