Contact your local county Extension office through our County Office List. Print this fact sheet. Enterotoxemia is a frequently severe disease of sheep and goats of all ages. It is caused by two strains of bacteria called Clostridium perfringens — the strains are termed types C and D. These bacteria are normally found in low numbers in the gastrointestinal tract of all sheep and goats.

If that is so, when and why do they cause disease? What appears to trigger them to cause disease is a change in the diet of the animal. As the organism grows in number, it releases very potent toxins bacterial poisons that harm the animal.

These toxins can cause damage to the intestine as well as numerous other organs. This can result in fatalities, particularly in the non-vaccinated animal or in the newborn lamb or kid whose dam has not been vaccinated. This posture is caused by the effects of the toxins on the brain. Death commonly occurs within minutes to hours after this sign is seen. Treatment of enterotoxemia may not be successful in severe cases. More severe cases may require intravenous fluids, antibiotic therapy, and other types of supportive care, such as supplemental oxygen.

Prevention of enterotoxemia is far more likely to be successful than trying to treat the disease. Vaccination is the cornerstone to prevention of this disease. For sheep and goats, there are multiple vaccines available that induce immunity to the toxins generated by Clostridium perfringens types C and D. Because tetanus is also an important disease to prevent in sheep and goats, many veterinarians recommend that sheep and goats be vaccinated with a vaccine that also induces protection against tetanus.

Adult sheep and goats: These doses are usually administered 10 to14 days apart. Once each adult sheep or goat has received these two doses, repeat vaccination should occur at least once per year.


Many veterinarians recommend that ewes and does be vaccinated roughly one to two months ahead emterotoxemia the anticipated birthing date, in order to maximize the amount of antibody present in the colostrum first aplacas — this helps to protect the neonate against enterotoxemia. If immunization of pregnant animals during that time frame is not feasible for you, then vaccinating the ewes and does at other times of the year appears to be effective.

For juvenile and adult sheep or goats fed diets rich enteritoxemia grain or allowed to graze lush pasture, more frequent vaccination for enterotoxemia may be warranted; some producers immunize these higher-risk animals two to four times per year to achieve adequate protection.

Keeping the mothers well-vaccinated is the best way alpaacs protect newborn animals against this disease, as the antibodies to the bacterial toxins are transferred to the newborns in the colostrum first milk. Obviously, you need to ensure that newborns receive colostrum for this to work! Growing babies are typically vaccinated for the first time at six to 10 weeks of age, and one to two repeat booster vaccinations are typically given afterwards.

Consult your veterinarian to determine what wnterotoxemia strategy best suits your alpacs and feeding program. Smart feeding strategies will also enable you to limit the potential for this disease to affect your herd or flock. Since the causative bacteria proliferate in the intestine in response to ingestion of abnormally high levels of starch, sugar, or protein, you need to be careful how you feed certain feedstuffs that contain high levels enterotosemia these nutrients, such as grains, silage or haylage, lush pasture, milk or milk replacer, and protein supplements.

Complete feeds — such as pellets designed to be fed to induce gain in lambs or kids — can also trigger this disease if fed in excess. When feeding these high-risk feedstuffs, divide the daily allotment for each animal into as many small feedings as is feasible say, three to four feedingsrather than providing such feeds in a single, large meal.

It is also advisable to feed roughages such as hay before feeding these higher-risk feeds, simply to allow the animals to become full on hay beforehand.

Enterotoxemia (Overeating Disease) of Sheep and Goats – – ExtensionExtension

alpacqs This helps to limit the potential for overeating on high-risk feedstuffs, such as grain. Consult your veterinarian to determine what feeding strategy is optimal for your situation.


Always make feed changes slowly. If you plan to increase the amount of grain fed to a flock or herd, always do so in gradual increments over several days. This helps the bacteria in the stomach to accommodate to the diet, making it less likely that the troublesome bacteria will get access to the nutrients.

Make sure that you watch your animals for signs of dominance by one or more individuals — they can boss the others away from the grain and overeat; alternatively, the shy animals can hold back from feeding and become so hungry that they overeat.

Divide your herd or flock as necessary, and make sure to provide an adequate number of feeding sites or feeder space to enable all animals an equal chance to eat. For animals being turned out onto pasture after being fed hay or other stored feeds, a conservative thumb rule is to begin by allowing only about 10 minutes of grazing time on the first day.

Double this with each subsequent day — it will take about a week for them to work up to a full 24 hours on pasture.

Heavily milking dams may need to be fed more roughage and less concentrate to limit the excessive milk production that might endanger their offspring. Keep the feed schedule consistent to lactating does and ewes to limit fluctuations in milk volume for their nursing offspring.
