After seeing some serious problems with burning (by a vet)on my wether brush eaters, I was too afraid to have it done, so when I got a Jersey heifer, I used the paste, and it worked great. After a year, she looks polled with zero growth.Babsbag, Southern? How about the results? I'd be very interested at this point. I'm pretty sure the injection site is around the base of the bud. As that is the source of any new growth.
Further, i would guess that if it works with new kids, it may also work on scurs.
I disbud by burning.
I've tried both paste and burning and will NEVER, ever use paste on a bud again!
However, with advanced scur growth, I have found that I can put a little paste around a banded scur and the scur will come off MUCH faster with out the discomfort associated with pasting a kid's buds. I put the band on, then rub paste into a piece of gauze and wrap it tightly around the band with a piece of elastoband, so the goat can't rub it off. The scur comes off pretty quickly.
