When and how to deworm your horse 


You will probably have read or heard in recent years about the resistance of equine worms to some of the active ingredients in equine wormers.

To make sure the active ingredients remain effective for as long as possible, wormers should only be used as necessary.

You could follow a worming flow chart and worm according to the horse or ponies Faecal Worm Egg Count (FWEC) results. A FWEC is a faecal sample which is sent to a laboratory to identify the content of worm eggs in the horse’s droppings. This gives a fairly accurate picture of the horses current worm burden.

To collect a faecal sample:

Collect the sample when the horses has been stabled or stood in an individual area so it can be accurately identified as their own dropping

Put a fresh faecal sample into a freezer bag for each individual horse

Samples should be less than 12 hours old

Ideally collect three nuggets of poo per horse

Label the bag with the horses name and the date and your surname

Take samples to the vets as soon as possible or send via a postal service specialising in this service

If your horse has worms, you will notice them in their faeces
