In this complete guide to CDT for goats, we answer the most common questions that farmers ask about CDT, including what it is, dosage amounts…and much more!
What is a CDT Shot for Goats?

“CDT” or “CD&T” is a commonly known vaccine for type C+D Clostridium perfringens and tetanus. It is a vaccine that should be used by farmers who are raising goats. These are widely available vaccines and are necessary to keep goats healthy. A bacterium knows as Clostridial found in the soil and this can cause sudden deaths due to which CDT vaccines have taken into account.
What are the Goat CDT Symptoms?

Clostridial diseases are repeatedly fatal and strike broody livestock and cause deaths without any symptoms. These bacteria are ubiquitous in surroundings and most commonly found in soil. They may also present in healthy animal’s tissues and in the digestive tract. Like Overeating or enterotoxaemia disease is the primary cause of death of kids and it originates from the bacteria known as clostridium perfringens.
The disease is characterized by the convulsions, acute indigestion and nervous systems signs such as sudden death or colic. Mostly, it affects the female goats nursing the kids, goats consuming high energy diets, and kids. Adequate feeding and management are essential to control the disease.
Another fatal disease known as ‘tetanus’ is common in goats. A bacterium knows as ‘Clostridium tetani’ is the leading cause of it. The main symptoms in this disease could be spasms and muscles stiffness, panic, inability to eat and drink and uncoordinated walking. This disease is deadly and it causes death of the goats after three or four days. Because of these issues, CDT vaccination is the best and most suitable way to prevent these diseases.
What is the CDT Vaccine Dosage for Goats?
Female goats (does) |
---|
CDT vaccinations should be given to does approximately 30 days before giving birth to a freshen. This early vaccine will provide a shield to the kids and will transfer the immunity to them through colostrum or the first milk.
The pre-kidding vaccination shot is of no use, if the two shots of priming booster is not given to the female goat with a gap of three to four weeks. Two shots of priming booster are delivered, preferably provided when the doe is young. However, the female goat can have these booster doses at any stage of their life. |
Kids |
---|
Kids should have the vaccination at the age of five to six weeks and must have a booster dose with an interval of three to four weeks. Vaccination of kids from a properly vaccinated female goat, before five weeks of age, may give undesired output like they have not gotten the vaccination, and the boosters doses may also become ineffective.
Furthermore, kids born with an uncertain background of vaccination or having doubtful colostrums ingestion should have the vaccine with seven to twenty-one days of the age. Administration of the booster dose should take place after a three to four weeks interval. |
Bucks (male goats) |
---|
Annual booster to the breeding bucks or the other adults should get 30 days before the breeding season starts or when the herd is about to get the booster vaccines. Moreover, if new bucks are there with unknown vaccination background, then those should get two doses in the beginning, with a gap of 3 to 6 weeks and later every year. Some of the researches showed that goats get benefits from the boosters vaccination when the boosters are given twice a year with six months difference. |

How Often Do Goats Need CDT Shots?

CDT shots protect goats from diseases like enterotoxemia, tetanus, and some other conditions. Mostly, for goats, CDT vaccines are required. Thus the dosage for CDT vaccine is fixed. For instance, female goats should have CDT vaccines during the fourth months of pregnancy. In contrast, the kids should get the vaccine when they become one month old and then the second dose one month later. Kids and female goats should have boosters every year.
Where to Give CDT Shots on Goats?
CDT shots are given by subcutaneously (under the skin) method, which means that it usually is given by pulling up some part of the skin. Insert the needle parallel to the long axis of the body into the base of the skin. The steps are:
- Prepare the skin and clean that area of skin before injecting the vaccine. The most preferred sites are behind the elbow or under the foreleg area, in the flank area, over the blade of the shoulder and side of the neck.
- The needle should be inserted in the angle facing downward toward the ground so there will be fewer chances of drug leakage after insertion of the needle.
- Observe the site of the animal to be sure that the needle doesn’t cross the blood vessel. Be sure that the needle is not in the blood vessel by pulling back the syringe and observe the blood in it. If blood came out, then remove the syringe and try again on another site, otherwise slowly depressed the plunger till the content disappeared.
- Massage that area and do not give medication more than 5 ml.
Where to Give CDT Shots to Baby Goats?
There is two most common method use for giving injections to the baby goats. One is intramuscular also indicated as ‘IM’ and subcutaneous (SQ) under the skin. Intramuscular, as its name suggests it, goes into the muscle and subcutaneous method just got under the skin.
CDT vaccinations are mostly subcutaneous type which means that these are given under the skin. The method of giving shots to the baby goat is quite similar to that of goats. ‘Tent’ method is used with the needle length of 1 and a gauge of 18 to 20.
At the site of the injection, pulled up the loose skin. The direction of needle and syringe held parallel to the body and needle is pushed inside the skin to enforce the vaccine.
The dose of the vaccine for baby goats is 2ml but it is not very common that a CDT injection site could develop for an abscess, so the region behind the base of front legs known as armpit is suitable for CDT vaccinations.
