Fern Hollow Farm vaccinates our goats with an annual CDT vaccine. The CDT vaccine is effective against enterotoxemia (overeating disease) caused by Clostridium perfringens types C and D and tetanus.
Enterotoxemia caused by Clostridium perfringens type D is often known as overeating disease. The bacteria is naturally found in the soil and in the gastrointestinal tract of healthy sheep and goats. In specific conditions, the bacteria can flourish and produce large quantities of toxins (Hines - College of Veterinary Medicine - University of Georgia, 2013). The disease gets its common name of “overeating disease” because the bacteria flourishes if and animal overindulges in grain or other feeds
Goats are susceptible to the tetanus bacteria found in the soil and environment around them. The bacteria can enter the animal through open wounds including castration and disbudding.
We prefer the Durvet GoatVac C.D.-T brand of the vaccine. We have noticed minimal vaccine abscesses with the Durvet brand compared to others we have tried. Additionally, this brand is carried in both our local Tractor Supply Co. and Fleet Farm stores. The dosage size is 2 mL regardless of the animal age or size. A 10-dose bottle will cost approximately $8-$10 and any unused liquid should be disposed of after puncturing the seal.
When to vaccinate?
Does should be vaccinated approximately 30 days prior to their kidding date. Protection is provided to the kids through the does’ colostrum. Kids should receive their first CDT vaccine at about one month of age and a booster shot 4 weeks later (follow brand specific instructions). In following years, goats should receive one dose annually. We recommend giving any new animals brought onto the property two doses unless their vaccination history is shared by the previous owner.
How to vaccinate?
Giving a vaccine to a goat is a quick process. Ensure there is no air in the needle or syringe prior to administering the dose. Most vaccines are administered subcutaneously (SQ) under the skin. Create a tent of skin by pinching up an area of skin and inserting the needle into the base of the tent.
We prefer to administer CDT vaccines behind the elbow of front leg of the goat. Vaccines can often cause swellings or “knots” that recede over time. Giving a vaccine behind the elbow can prevent confusion with abscesses caused by caseous lymphadenitis (CL) that often appear in the neck or shoulder area.
Do not vaccinate animals within 21 days before slaughter.
