Animal health company Merial has introduced four simple rules to help horseowners plan an effective worming programme, with the aim to control worms with simple monitoring and tracking online at www.smartworming.co.uk.

Recent research has shown that allowing the horse to keep a low number of worms in their system can be beneficial. Keeping a low population of treatment-sensitive worms in the horse is called ‘refugia’, which simply means that this low level of worms will act as a reservoir.

A small number of treatment –sensitive worms helps to dilute the number of treatment-resistant worms that are developing, whereas worming too frequently will deplete the number of treatment -sensitive worms, leaving only resistant worms in the gut which cannot be eradicated with wormers.

Understanding Faecal Worm Egg Counts

The worming experts at Pfizer Animal Health and Westgate Laboratories have combined their expertise to help horse owners understand why Faecal Worm Egg Counts (FWECs) are one of the most important tools to help with summer worm control.

David Booth at Westgate explains: "A Faecal Worm Egg Count simply involves collecting a sample of fresh dung and sending it, in the special packaging provided, to a specialist laboratory. There it will be analysed and the number of worm eggs in the sample will be measured and reported back to you as eggs per gram. Results and worming can then be discussed with an experienced animal health advisor."

Ben Lacey at Pfizer agrees: "FWECs are invaluable during the grazing season as they will indicate how many eggs each horse is contributing to the contamination of your pasture. Eggs hatch into worm larvae, so the higher the egg count the more larvae will be on the grazing - increasing the risks of re-infecting all the horses with worms.

Conducting regular FWECs can help you to target your worming treatments by only dosing horses with a significant worm burden, which will stop them from re-infecting the pasture for a period after the treatment. The horses with low egg counts are less likely to need a treatment as they are not contributing as many new worms onto the pasture. The test can also give you an indication of whether your wormer is working, if you take a FWEC before and after administering a wormer.

"It is essential to remember though that a standard FWEC will not give a clear indication of tapeworm, encysted small redworm or bots. For these you will need to use a proven wormer on a strategic basis – usually in the autumn and spring for tapeworm and late autumn/early winter for encysted small redworm."
