What Is A Normal Egg Count For Horses?

Published by Clayton Newton on

Fecal egg count tests primarily identify small strongyles (redworms) and ascarids (roundworms).

Classification based on egg shedding Egg Count (per gram of feces) % of horse population
Low 0 – 200 50% to 75%
Moderate 200 – 500 5% to 15%
High >500 10% to 30%

What is a high faecal egg count in horses?

500 eggs per gram
A faecal egg count (FEC) is performed on each horse at intervals according to the egg reappearance period of the dewormer being used, and horses are categorised as high shedders (those with a FEC of greater than 500 eggs per gram [EPG]), moderate shedders (200-500 EPG) and low shedders (FEC of less than 200 EPG).

What is an acceptable worm count in horses?

200 eggs per gram
It is generally recommended that you worm your horse if the result is 200 eggs per gram or above. Your vet will be able to give you advice on a suitable wormer. If the result is under 200 eggs per gram, you will probably not need to worm your horse.

What is a high worm count in horses?

<200 EPG – negative or very low worm burden – no need to worm. 200-1200 EPG – moderate worm burden – suggest horses in this category are wormed. >1200 EPG – high worm burden – this level of worm burden will require a vet to discuss your worming programme and make changes/treat accordingly.

What is the normal acceptable parasite count in faeces?

You can classify your worm count as either low, moderate, or high. A faecal egg count of fewer than 100 eggs per gram of faeces is considered low. A count of between of 100 and 500 is considered in the moderate range and anything above 500 is considered high.

Can a horse live with EIA?

Horses that survive the acute phase of infection become lifelong carriers that pose a transmission risk to other horses. EIA-positive horses must be identified and isolated (at least 200 yards) from other horses or euthanized to prevent the spread of the virus.

What are some signs a horse may show when they have a severe internal parasite infestation?

The signs of parasitism are common among different parasites infecting the horse and include:

  • Weight loss.
  • Dull, rough hair coat.
  • Potbelly.
  • Decreased stamina or lethargy.
  • Coughing.
  • Diarrhea.
  • Colic.
  • Tail rubbing.

Which 3 parasites cause the most damage to the horse?

Probably the most important, in terms of health risk, are the first three: small strongyles, roundworms, and tapeworms. The lifecycle of most internal parasites involves eggs, larvae (immature worms), and adults (mature worms). Eggs or larvae are deposited onto the ground in the manure of an infected horse.

Can you worm horses too often?

Overuse of deworming products leads to resistance. Worms can develop genes that allow them to become resistant to the dewormers — making the medication ineffective. Resistance limits our ability to treat horses with worm problems. These issues can lead to severe colic and death in affected horses.

What is a worm egg count?

Using Worm Egg Counts
A faecal egg count (FEC) counts the number of worm eggs in faeces (dung) and is used to monitor the worm burden in sheep. The results are presented as ‘eggs per gram’ (epg) of faeces and the number of eggs is an indication of the number of adult worms in the gut of the sheep.

What horse wormer kills all worms?

The larvicidal dose of fenbendazole, Panacur® POWERPAC, is the only dewormer proven to treat all stages of encysted small strongyles, including the early third-stage that encyst.

Should you worm your horse every month?

Our Gillette vets recommend deworming most horses once or twice a year. Before having your horse dewormed in the spring, a fecal exam should be done in order to measure the number of worm eggs being shedding in your horse’s feces.

How many times a year should a horse be wormed?

How often should a horse be wormed? Traditionally, veterinarians recommend worming your horse every two months.

What can be mistaken for parasites in stool?

Yeast and other fungal elements are common in stool. Depending on the size and shape, they may be confused for a variety of helminth and protozoan species.

Why are faecal egg counts important?

Faecal worm egg counts (FEC) are very important indicators in assessing the intensity of helminth infections in animal hosts and inform decisions taken in parasite control programmes.

How accurate are stool tests for parasites?

These findings indicate that at least three stool specimens should be examined to confirm the presence of intestinal parasites. Even with such practice, it is not possible to guarantee that there is no infestation, but examination of fewer specimens would run a definite risk of false negative results.

What happens if a horse tests positive for EIA?

As there is no known treatment for EIA and infected horses become lifelong carriers posing a risk to other horses, any horse confirmed positive for EIA must be quarantined and isolated 200 yards away from all other horses. If appropriate isolation is not available, the owner may opt for humane euthanasia.

What happens if a horse tests positive for Coggins?

For this reason, horses that test positive for Equine Infectious Anemia must either be euthanized, branded and strictly quarantined more 200 yards away from other horses for life, or transferred to a research facility.

How contagious is EIA?

Key Points. Equine infectious anemia (EIA) is a noncontagious infectious disease of equids caused by a virus of the same name. It is not known to be transmissible to humans. The principal mode of natural transmission of EIA is on the mouth-parts of blood-feeding insects, especially horse flies and deer flies.

Should I worm my horse before or after food?

Tips for deworming:
Give the dewormer before feeding your horse their grain. Or, if the horse has a mouthful of hay or grain, remove them from food sources for a few minutes. If their mouth is full of food they will spit out the dewormer with the half-chewed food.

How long do worms live in horse manure?

The larvae will remain in the horse’s digestive system for around eight to ten months, before passing in the manure. They will then pupate in the soil for three to five weeks before emerging as adults, ready to start a new cycle.
