The difference between Tetanus Antitoxin
versus Tetanus Toxoid

Tetanus Toxoid:
Helps the body to develop permanent immunity against Tetanus.  The kids should be vaccinated within 1 month of age if the dam was not vaccinated 4-6 weeks prior to birth if kid.  If dam was vaccinated, then each kid is vaccinated again at 4 weeks of age (see CD & T below) then a booster given annually along with all adult goats and sheep.

Tetanus Antitoxin:
Gives temporary protection for about 2 weeks but does not give permanent immunity to tetanus.  It is used prior to surgery, disbudding, castrating or any open wounds.   It is also used for treating animals with tetanus but is not always successful once the animal has contracted tetanus.  

CD & T:
Vaccination called Clostridium perfringens Types C & D and Tetanus is used to prevent and treat enterotoxemia (over eating disease) and Tetanus.   The kid at birth is protected if the Dam was vaccinated 4-6 weeks prior to kidding.  The kid is vaccinated at 4-6 weeks of age.
