Faecal Egg Counts (FEC)

The high value of horses and the need for maximum performance means that it is essential to control worms adequately.  A severe worm infection can emaciate, debilitate and even cause death in horses.  Even a mild infection can seriously affect the development and performance of your horse.

To effectively manage worms, the decision to treat must be an informed one.  You may not need to de-worm at all, or you may find that you should have de-wormed earlier.  Faecal Egg Counts (FEC) are at present the only satisfactory way of deciding when to treat your horse.

The usual practice of dosing at regular intervals may therefore mean that you are worming your horse when no eggs are present.  Thus you may be encouraging the development of resistant worms and wasting time and money.  There is a wide variation in FECs between individual horses, however most owners worm as a group.

Widespread international prevalence of resistance to two of the three worming base drugs available leaves only one fully effective class of chemicals remaining.  Resistance occurs when worms are exposed to a drug repeatedly.  Over time they genetically alter to survive the drug.  Resistance can develop through importation, over-use, under-dosing and mis-timing of treatments.

Ross Anthony Livestock Services Ltd uses FECPAK to provide you with FEC's for your horse.  The FECPAK unit is a customised, purpose built product for calculating quick and accurate FEC.  The Equine testing system has been refined to be more sensitive, accurate and repeatable than other methods.

A good worm control programme is invaluable to maximise your horse's health and performance.  95% of all worms on your property are on the pasture, only 5% are within the animals.  So how do we minimise the worm larvae numbers on the ground?  FEC give an accurate indication of the contamination levels being produced by the animals, providing a method of managing pasture contamination and helping avoid further infection of other horses.

We can either come to you and collect samples or you may post or drop them off with us if this is more convenient.  We will then provide you with a prompt FEC and advise you of a suitable worming strategy.  Regular monitoring will allow you to develop unique management strategies and enable you to spend less time and money on worm control without compromising your horse's health.

Financial benefit (Information provided by Innovis).

Save on wormers:

  • Assume by using FEC that over the grazing season 2 whole doses per horse are avoided.
  • Assume average no. horses = 10
  • Assume the price per dose of wormer = £10 (based on average 500kg horse)
  • The cost saved = £200

CAUTION!!  FEC will not detect encysted stages of small strongyles or accurately portray tapeworm burden, therefore it is recommended to worm as directed for these species.  Please consult your vet for more information.

  • RALS Ltd recently carried out worm egg counts for a local livery yard, samples for 10 horses were looked at under the micrscope and whilst 2 horses had higher levels than the others, none were above the threshold level for needing worming at the present time. All owners have benefitted by saving money and the horses and environment have benefitted from not being subjected to unnecessary chemicals - everyone's a winner!

Equine Strongyle EggAll our worm egg count kits are supplied with comprehensive instructions and management tips.  Envelopes are all pre-paid making the process as easy as possible for you,  However if you are a local farmer or horse owner then we may be able to call in instead to collect the samples or you can drop them off with us.

We can also offer discounts for larger groups of horses and for those who wish to set up a programme to use our services regularly - let us take the guesswork out of worming and drenching for you and allow you to do so more objectively.
