[QUOTE="regolith, post: 1616103, member: 9267"] I'm using allflex NAIT tags... can lose up to 10% annually several with ears ripped. NZ government claims they don't come out and aren't interested in animal welfare. At least, I conclude that they aren't interested in animal welfare on the evidence that they insist on every calf being tagged full-time with these things even though farmers keep telling them they're shredding ears. Two calves out of thirty born this spring have ripped ears, I know for a fact one did it on a bit of string hanging on a gate, because that's where I found the tag. edit to add: my whole herd had tags scanned at TB testing nearly a year ago... that's a thing now. Just 5 tags found missing, ears not ripped but I think four of those cows would have been born 2009 - 2011. Which strongly suggests to me that those things have a half-life of not more than nine years. Previous time the herd was scanned was just two years after they were all first tagged, and we put in 10% new RFID tags as the originals had been lost. [/QUOTE]
