[QUOTE="Lucky_P, post: 1800930, member: 12607"] The very first case of tetanus in cattle that I ever saw (in my 3rd year in veterinary school at the time) was in one of my very own home-bred steers - which I 'cut', with a Newberry knife, at about 400 lbs. Found him 'sawhorsed' out in the pasture about 2 weeks later. So... knife castration is not without risk, but in my estimation, is less risky than banding without adequate protection. I have seen more than one 'trainwreck' with a large group of 5-7cwt bulls banded and a dose of tetanus toxoid administered at the time of banding, with fairly high morbidity/mortality rates, as the steers 'lost the race' between mounting an immune response and the production of tetanus toxin by C.tetani bacteria growing in the anaerobic devitalized tissue of scrotum and testicles. I do not recommend banding without prior vaccination and boosting at time of band application - or administering tetanus antitoxin (TAT) at the time of banding. I have seen a few cases of tetanus in baby calves banded with the little green Cheerio, but given the millions of those that have been applied over the decades, it's a low incidence. That said, a dead baby calf has a distressingly low carcass weight , just like a dead 800-pounder... you just don't have as much invested in the neonate. Tetanus toxoid (TT) as a stand-alone, or a 8- or 9-way Clostridial bacterin-toxoid containing TT... either way works. I always use Covexin-8 or Cavalry-9 on all calves, as several years back, we lost a 4-month old heifer to tetanus... and never knew what her exposure/infection route was - but we'd not been vaccinating against tetanus prior to that one.
