We have used Allflex Babe tags for several years, we have never had them ripped out of the ear with this brand, just one that pulled through a bit. However the fins have been breaking off, leaving the pins in the ear, and we are having to keep replacing them, Allflex claim to have improved the Babe tags now but last year we decided to change to Allflex bubblegum tags, these have the same pins which we have been happy with, as prior to using Allflex had had several torn ears (used Ritchey and Ketchum previously but now several years ago). We had no tag loses from last years lambs with the Bubblegum tags, over 100 lambs, and so are using these again this year and hoping they will last longer than the Babes, they are 75p a set of breeding tags and since we started ordering them direct they have arrived quickly. Have kept with Allflex as despite the problems with the fins on the Babe tags we are really pleased not to have any ripped ears from their tags over the last 6 to 7 years we have been using them.
nb if using their slaughter tags I would also recommend the bubblegum tags over the others with the thinner pins as these didn't stay in, better for using if you don't tag until they go for slaughter though due to the thin pin.
