your adult cows and bulls for blackleg? If vaccinated will it pass some protection to the unborn calf?

The "closed herd" mentality doesn't set well with me. You have to bear in mind all the places around me run cattle and some bust fences.

Anything over two yrs old we do not vaccinate for blackleg. Only 3 months to 2 years get vaccinated for it. Never had any trouble doing it this way. It could perhaps put the blackleg antibodies in the colostrum if you vaccinate a bred cow. In my opinion vaccinating anything over two years of age is throwing your money away just like vaccinating newborn calves is throwing money away as the immune system is not developed yet. It is extremely rare for a cow over two years of age to get blackleg. At least I have never seen any that have.
