I got told they can rip out but probably a low percentage
They must be above cartilage ridge line. Below and gravity will slowly do its thing.
We have had them in over a year (100 tags) and 2 tags have failed a been replaced as they are leased (would still be under warranty anyway) 1 has come out and is lost.
It was a fabdec heat time system. We had 300 cows and only like 200 collars so we’re always taking them off stale cows and putting them back on fresh calvers. The collars were just a pain in the arse to adjust to fit each cow properly especially once they’d become a bit worn and got full of dust and crap. This was nearly 15 years ago mind they might have moved on since. I haven’t had much experience recently been using scratch cards!! Did have auto ID on last parlour which relied on ear tags and can’t recall a cow losing one.
I wouldn’t be wanting to shift collars all the time, I’d be having the collar on the same cow until she’s gone. Save a bit of money mind you changing the collars !
You definitely want a head scoop on the crush if changing collars frequently
Absolute PITA without a collar a cow. Will go onto our third collar based system shortly, SCR the first couple of times, the second LD system has been superb, AFI the third time after being promised good things from Boumatic and then letting us and a few other farmers down.
You got monty’s?
Who is afi?
Used to have quite a few but moved farms
Iv heard nothing but good things, but the poor girls already have 3 tags in them already !
Israeli electronics firm. Make the meters for Fullwood and electronics for other firms.
. Would have to be a tag based system for me!
