What Is Ergot Poisoning In Horses?

Ergotism is a worldwide disease of farm animals that results from ingestion of sclerotia of the parasitic fungus Claviceps purpurea, which replaces the grain or seed of rye and other small grains or forage plants, such as the bromes, bluegrasses, fescues, and ryegrasses.

What causes ergot on horses?

Ergot poisoning- The most frequent culprit that causes ergot alkaloid toxicity is the fungi in the Claviceps family. It is most often found in the form of Claviceps purpura (rye ergot fungus), which is parasitic to several types of grass and cereal, most notably rye grass.

What does Ergot poisoning do?

Early symptoms of poisoning include nausea, vomiting, muscle pain and weakness, numbness, itching, and rapid or slow heartbeat. Ergot poisoning can progress to gangrene, vision problems, confusion, spasms, convulsions, unconsciousness, and death.

Can Ergot poisoning be cured?

How Can Ergot Poisoning Be Treated? There is no antidote, so treatment involves removing the animals from the source of the ergot and alleviating the symptoms. If found early enough and before severe clinical signs develop, animals can recover, but once gangrene has started, there is little treatment.

What is ergot in grass?

Ergot is a plant disease caused by the fungus Claviceps purpurea, which infects the developing grains of cereals and grasses. Ergot symptoms become evident during kernel formation, when ergot bodies are formed in place of kernels.

How do you get rid of ergots on horses?

It is easier if you soak the area with water first to soften them up. The chestnut can often be peeled away by hand. The ergot can sometimes be peeled away, but more often, you might need a pocket knife. Be careful not to trim them to close.

In less wealthy countries, ergotism still occurs; an outbreak in Ethiopia occurred in mid-2001 from contaminated barley. Whenever there is a combination of moist weather, cool temperatures, delayed harvest in lowland crops and rye consumption, an outbreak is possible.

How common is Ergot poisoning?

Ergotism is rare in human populations but most likely is underdiagnosed in animals. The most logical approach to managing ergotism is the removal of animals from the source of ergopeptine alkaloids.

How can Ergot poisoning be prevented?

Prevention and Control of Ergot Poisoning
Prevention is based on feeding feed and forage that are free of ergot. For pastures, graze the infected fields before seed heads begin to flower. The ergot is contained in the ovary of the flower. Commercially prepared feeds will rarely contain ergot.
