gateboy,
You didn't see that from ME!
I use a Burdizzo, almost exclusively, but do not cut them. No reason to cut anything if you're clamping with a Burdizzo.
Back in the day, when I used to cut them, I did just slice the bottom 1/3 or so off the scrotum and pull out testicles.
ttimber,
I switch around between Covexin-8, Cavalry-9... if I can get C-9, I do, 'cause it's a 2ml dose... but sometimes I'm in a hurry, and have to go with what I can get my hands on at the local Southern States, and that's usually C-8. It's not all that unusual for calves to be a little slow or achy-looking the next day or two after vaccination, but I don't really worry about it.
Anaphylactic reactions can happen; lost one calf to anaphylaxis 8-9 years ago after giving a 5-way Clostridial (not C-8 or C-9);
