Eric, I thought castrating with a knife went out with the ark. Not something I would attempt for reasons already mentioned.
Normally all our bull calves are rung by the time they are 3 weeks old but the odd one slips through for various reasons. At present I have one 7 month bull calf that the vet will be coming out to deal with on Thursday because he is now too big to get a ring on. He will still be rung with but what I think you call a Burdizzo. Most small farmers here don't own one as calves are rung with the usual small bands at a young age - and if they're not, they should be, my own included. I'm not about to take the risk of losing a beef animal that will be worth big dollars to a knife for the sake of spending $50.00 on a vet to do the job properly.
Cheers,
Ronnie
