Registered brandings perhaps ? Cant fall off, cant have dodgy the dodger cut and replace tags in 10 seconds.....
It is not bad, only when it becomes law, cause then only the lawless are free....so do not get me wrong, it is a move that in principle, and maybe even a lot of practice, is a good thing. It is legislating stuff that irks me.
Think of if I graze a few hrs 3 times each day next door, and the owners cant be bothered being registered, or maybe they are, so I am a law breaker if I do this....and am I really going to make multiple records daily of hundreds of different animals. Like there is nothing else to do.
Point being, some things are great in theory if you sit in an office on the public teat....this system does not stop mr dodgy, not one bit, I could shoot holes through this everywhere...
What it is good for, is greasing the wheels for a few companies, the govt, yards and agents or interested parties.
