We do not vaccinate at all. I can see the use of one vaccination when they are babies, but personally I do not feel or see the need to vaccinate on a regular schedule of a couple times a year. It seems unnecessary and a goat should have developed immunity to the disease after 1 or 2 shots. That is just my 2 cents. When my buck and wether got dehorned I had the vet give them the tetanus antitoxin just in case.
Even though we do not give vaccinations, it does not mean that we don't do anything at all. We give nosodes, which is the homeopathic version of a vaccination. We give nosodes for entero, tetanus, orf(soremouth) and E Coli. To safeguard against entero, we always keep baking soda out free choice, and if we have a goat that goes off feed or acts off, they get a shot of Fortified B Complex along with a dose of thiamin. We also give Milk of Magnesia and olive oil to encourage rumen function during the sick time.
As tetanus prevention, besides giving the nosode, anytime a goat gets cut or scratched, we immediatly clean the wound out with peroxide and put calendula and/or hypericum tincture on the wound. We also give the remedies Ledum(for open wounds and bites), Hypericum(for repair of damaged tissue and prevention of infection) and Arnica for pain.
We have never had a goat come down with tetanus or entero by doing these things.
