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.
Here at Blue Cross we 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.
The results of the FWEC are provided as ‘eggs per gram’ (epg). We do our FWECs in March, June and September.
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
Limitations are that FWEC’s do not detect:
Tapeworm burdens - so we tapeworm test in April, this is a postal saliva test provided by Equisal and we worm according to the result
Encysted or immature strongyles therefore we worm once a year in mid-November with moxidectin
Benefits of using this program
Targeted treatment of worm burdens (rather than blanket worming)
Preserve the effectiveness of current wormers
Reduce costs by reducing wormers used
Less chemicals for the horse to process

We provide free pet advice as every pet deserves to be well looked after. We treated around 35,000 sick injured and homeless pets last year. We're so glad we've been able to help these pets who are unable to help themselves, but there are thousands of sick and lonely pets still in need, so we need to ask for a small favour.
All of our work is funded entirely through donations. People like you are essential to our work. If everyone who benefits from our articles is able to give a little back, we can reach thousands more pets. For as little as £1 you can make a difference - do you have one minute? Thank you.
