WHY WORM COUNT ?

 

 

In Spring 2010, the British Veterinary Association (BVA ) issued new guidelines on the responsible use of anthelmintics  (wormers) for all grazing animals.

 

 

Resistance to anthelmintics (wormers) is serious and increasing and if left unchecked could have a catastrophic effect on animal welfare.

 

 

Every exposure to a worming dose increases the risk of resistant worms developing and we may ultimately be left with a situation where there are no effective drugs to treat infected animals.

 

 

One way of helping to avoid the build up of resistance is to change from the traditional interval dosing style worming programme and introduce a targeted worming programme using faecal worm egg counts.

 

 

Used effectively this will ensure only animals that need worming are wormed and you can safely target the relevant drugs (wormers) to any parasites identified.

 

 

 

What is a faecal worm egg count?

 

 

A faecal worm egg count is a method of determining how many internal parasite eggs are present in a particular dung sample; in addition it is also possible to determine the different types of worms & other parasites present.

 

 

The Information on both the number and type of parasite/worms found in the sample can determine whether or not treatment or worming is necessary.

How does a faecal worm egg count work?

 

 

 

A worm count is best carried out when worming is due or overdue in spring, summer, or autumn.

 

 

A good sample of fresh dung is collected from several places in the pile and sent off to the laboratory for examination.

 

 

After undergoing several tests the samples are analysed and the final egg count results are calculated and this is expressed as ‘eggs per gram’.

 

 

If the epg (eggs per gram) count is less than 50 epg this means there was no trace of worm eggs when the sample was tested and under normal circumstances a horse will not need to be wormed.

 

 

If the count is less than 200 epg this is considered a LOW count and suggests existing worming measures that are in place are working.

 

 

If the count is between 200 epg and 1200 epg it is considered a MEDIUM count and the Equine needs worming.

 

 

If the count is more than 1200 epg it is considered a HIGH count and the Equine needs worming and indicates the existing worming strategy may need some attention.

 

 

 

What a worm count can do.

 

It will give a snapshot of the likely parasite burden of the Equine at the time of the test, which is best taken when worming is due or overdue during spring, summer or autumn.

 

 

The test can be used to identify wormy horses in a herd, to check for resistance to a particular worming product and to replace routine worming doses in an annual worming programme.

 

 

It can show strongyle eggs laid by adult redworms – the most important equine parasite.

 

 

It will show ascarid eggs, roundworm, usually only found in foals and neglected youngsters.

 

 

 

What a worm count cannot do.

 

Worm counts cannot treat a worm problem but are useful in identifying and monitoring one.

 

 

It cannot show encysted stages of redworm as these are immature and non-egg laying. It is however fair to say that by no means do all redworms encyst in winter.

 

 

It is not a definitive test for tapeworm as these parasites can infect the horse without eggs appearing in the dung samples.

 

 

It will not usually show pinworm eggs, though pinworms are usually obvious when they occur.

 

 

Be aware most targeted worming programmes will still need to include treatment for encysted redworm and tapeworm as a minimum, even if routine worm count results are good for the rest of the year.
